    BACKGROUND: This study assesses the safety and efficacy of hepatocyte-like cell (HLC) infusion therapy derived from human embryonic stem cells as bridging therapy for neonatal-onset urea cycle disorders (UCD). The research includes both preclinical and clinical evaluations to determine the feasibility of HLC infusion as a therapeutic option for safer pediatric liver transplantation. METHODS: Preclinical studies were conducted to validate the safety, biodistribution, and ammonia metabolism capabilities of HLCs using SCID mice models of UCD and extensive animal studies. In the clinical trial, five neonates with UCD received HLC infusions, intending to maintain metabolic stability and exceed a target weight of over 6 kg, which is considered necessary for safer liver transplantation. RESULTS: Preclinical studies demonstrated that HLCs successfully engrafted in the liver without adverse migration or tumor formation and effectively elongated survival. Clinically, all five neonates exceeded the target weight of 6 kg while maintaining metabolic stability and successfully bridging to transplantation. Post-transplantation follow-up revealed stable growth, metabolic control, and no neurological complications. CONCLUSIONS: The combined preclinical and clinical findings support HLC infusion as a viable bridge therapy for neonates with UCD, providing metabolic support to achieve safer weight thresholds for transplantation. While promising, careful monitoring remains essential, particularly for potential complications such as thrombus formation. TRIAL REGISTRATION: jRCT, jRCT1090220412.

    INTRODUCTION: Biliary atresia (BA) is a progressive cholangiopathy in neonates that results in biliary cirrhosis and liver failure without early intervention. Hepatic portoenterostomy (Kasai operation) remains the standard treatment, significantly improving survival rates. However, postoperative cholangitis is a major determinant of prognosis. To prevent cholangitis, various surgical modifications, including anti-reflux procedures such as intussusception anti-reflux valves (IAV), have been introduced. Although IAV has been widely adopted, some reports suggest that long-term survivors may develop afferent jejunal limb stenosis, leading to complications such as cholangitis and intestinal obstruction. Herein, we report a case of afferent jejunal loop stricture caused by IAV, which became symptomatic after liver transplantation (LT). CASE PRESENTATION: A 34-year-old man with a history of BA underwent Kasai operation with IAV and spur valve at 77 days of age. Despite experiencing recurrent cholangitis in adulthood, he survived with his native liver until developing liver cirrhosis and porto-pulmonary hypertension, necessitating deceased donor LT. Preoperative imaging revealed portal vein obstruction and dilated collateral circulation. During LT, severe adhesions and afferent limb dilation were observed, requiring a 30 cm resection of the jejunal limb. Postoperatively, he developed cholangitis, and imaging on postoperative day 16 revealed an anastomotic leak with an intra-abdominal abscess. Retrospectively, CT image before LT demonstrated the dilatation of the afferent limb and the stricture due to IAV was highly suspected. Double-balloon endoscopy confirmed complete afferent limb obstruction due to IAV-related stenosis. Surgical reconstruction with resection of the obstructed Roux-en-Y limb and creation of a new hepatojejunal anastomosis was performed. The patient recovered well and was discharged on postoperative day 45 without further complications. CONCLUSIONS: This case highlights the possibility for late-onset afferent jejunal stricture due to IAV in BA patients undergoing LT. The narrowing likely results from long-term fibrotic changes after 34 years from BA operation. Given the increasing number of BA survivors receiving LT, awareness of IAV-related complications is crucial. In cases with suspected afferent limb stenosis, preoperative assessment and consideration of jejunal limb resection during LT may help prevent postoperative complications.

    INTRODUCTION: Intrahepatic cholangiocarcinoma (ICC) is the second most common liver malignant tumor with a poor prognosis. Lymph node (LN) metastasis is found in 15% of ICC at the time of initial diagnosis. However, the LN metastasis to the anterior mediastinum is extremely rare. Herein, we report a case of anterior mediastinal LN metastasis of ICC. CASE PRESENTATION: The patient is a 74-year-old man who had surgery for cervical esophageal cancer. During follow-up, a low-density hepatic tumor and swollen LNs in the anterior mediastinum were detected. The tumor of the liver was diagnosed as ICC by needle biopsy. Excisional biopsy of the LN was performed and the diagnosis was metastasis of ICC. Because the prognosis of the patient with ICC Stage IVB is poor, the patient received 8 courses of chemotherapy. Although the new lesion appeared next to the main tumor, these tumors were located in the left liver. In addition, it was difficult for the patient to continue the chemotherapy due to the renal dysfunction. Hepatectomy with lymphadenectomy was performed. The patient survives without recurrence for 9 months after surgery. This is the first report of anterior mediastinal metastasis of ICC without any other organ involvement. CONCLUSIONS: Metastasis to the anterior mediastinum of hepatic tumor can be explained by the system that lymphatic fluid running under the capsule of the liver drains to the anterior mediastinal LNs through the coronary ligament. Metastasis of ICC to mediastinal LNs can occur when the tumor is located at the surface of the liver. Excisional biopsy is effective in determining the accurate disease stage and the treatment strategy.

    INTRODUCTION: Hypercoagulability-related graft thrombosis is the leading cause of graft failure after simultaneous pancreas-kidney transplantation (SPK). Addressing this issue is crucial to improve the outcomes of SPK recipients. Thromboelastography (TEG) has been used to assess the coagulation profiles of SPK recipients. Recently, a new-generation TEG device, the TEG 6s Global Hemostasis System, was introduced. This device offers advantages over TEG 5000, including less frequent calibration requirements, ease of use, and reduced sensitivity to movement. We hypothesized that TEG 6s would enhance coagulation management in SPK. METHODS: We report two cases of Asian female SPK recipients in whom TEG 6s was used to assess coagulation status at six preset times during and after surgery. RESULTS: Preoperatively, both patients exhibited hypercoagulability on TEG 6s. Postoperative intravenous heparin was administered, and the dose was titrated based on the TEG 6s results. Vascular thrombosis was not observed in either patient. Detailed TEG 6s and standard laboratory test results are reported. This pilot study demonstrates that TEG 6s monitoring can effectively assess coagulation status in SPK recipients, aiding in optimal coagulation management and reducing the risk of thrombotic complications leading to graft loss. The TEG 6s facilitated real-time and accurate coagulation assessment, allowing for tailored anticoagulant therapy. CONCLUSIONS: This is the first observational study to use TEG 6s in SPK recipients, indicating its potential benefits in improving patient outcomes. Further studies with larger sample sizes are warranted to validate these findings and establish comprehensive guidelines for using TEG 6s in SPK procedures.

    Biliary atresia is an obliterative cholangiopathy of unknown etiology. Hepatic portoenterostomy, in which obliterated extrahepatic bile ducts are resected and bile flow is restored, known as Kasai operation, is performed within 3 months after birth. While this operation enhances long-term survival of patients, the occurrence of primary malignant hepatic tumors has been increasing. We report a case of small intestinal adenocarcinoma arising at the anastomotic site after Kasai operation. A 49-year-old man, who underwent Kasai operation for biliary atresia when he was 2 months old, experienced rapidly progressive jaundice and liver dysfunction. Deceased-donor liver transplantation was performed for liver failure. Macroscopically, there was a white-yellow tumor located at the anastomotic site of hepatic portoenterostomy of the resected liver. Pathological examination revealed a well-differentiated adenocarcinoma with some Paneth cells in the neoplastic lesion. Immunohistochemically, the tumor cells were negative for cytokeratin 7 (CK7) but positive for cytokeratin 20 (CK20) and a homeobox domain-containing transcription factor (CDX2). Mucin expression in tumor cells was negative for mucin 1 (MUC1) and mucin 6 (MUC6) and positive for mucin 2 (MUC2) and mucin 5AC (MUC5AC). The pathological diagnosis was small intestinal adenocarcinoma originating from the jejunum. The patient was discharged 48 days after the operation. The patient had not experienced recurrence at 10 months after the operation. This is the first report of small intestinal adenocarcinoma arising at the anastomotic site after Kasai operation for biliary atresia. Special care should be taken for the patients after Kasai operation with acute progressive jaundice and liver dysfunction because there is a possibility of malignancy in their native liver.

    Tumor-to-tumor metastasis is a rare phenomenon in which primary tumor cells metastasize to other tumors. Herein, we report an extremely rare case of tumor-to-tumor metastasis of medullary thyroid carcinoma to a paraganglioma in a patient with multiple endocrine neoplasia type 2B. Based on genetic examination, a 36-year-old woman was diagnosed with multiple endocrine neoplasia type 2B when she was 24 years old. She had a history of total thyroidectomy for medullary thyroid carcinoma and bilateral adrenalectomy for pheochromocytomas, which were performed when she was 15 years and 29 years old, respectively. Follow-up computed tomography demonstrated a retroperitoneal tumor of 30 mm in diameter beside the left kidney and a liver tumor of 16 mm in diameter located in segment 6. The retroperitoneal and liver tumors were surgically resected and examined by a pathologist. Histological examination revealed the classic Zellballen pattern in the retroperitoneal tumor, rendering the diagnosis of a paraganglioma recurrence. Inside the tumor, a white nodule positive for carcinoembryonic antigen, weakly positive for calcitonin, and negative for tyrosine hydroxylase, was identified and diagnosed as a metastatic medullary thyroid carcinoma with high malignant potential. The liver lesion was diagnosed as a metastasis of the medullary thyroid carcinoma. This is the first report of tumor-to-tumor metastasis of medullary thyroid carcinoma to paraganglioma in a patient with multiple endocrine neoplasia type 2B twenty years after total thyroidectomy.

    BACKGROUND: After pediatric liver transplantation, liver fibrosis may occur during long-term follow-up. Noninvasive markers for assessing this liver fibrosis are desired. Mac-2 binding protein glycosylated isomer (M2BPGi) has recently been reported as a useful biomarker for liver fibrosis. However, its usefulness in the pediatric population is yet to be established. This study investigated the clinical significance of M2BPGi levels as a surrogate marker of graft fibrosis after pediatric liver transplantation. METHODS: We retrospectively identified 96 patients who underwent pediatric liver transplantation at our institution between 1991 and 2015. The association between M2BPGi levels and other fibrosis markers was analyzed in 60 patients in whom fibrosis markers were measured. The association between fibrosis marker levels and graft fibrosis was assessed in 42 patients who underwent biopsies between 2016 and 2022. RESULTS: The M2BPGi levels were statistically correlated with the hyaluronic acid and type-IV collagen levels. None of the fibrosis markers were significantly associated with liver graft fibrosis, although the levels of these markers were slightly higher in patients with severe liver fibrosis than in those with mild fibrosis. CONCLUSIONS: The M2BPGi levels had a limited ability to assess liver graft fibrosis after pediatric liver transplantation, similar to other fibrosis markers. Further studies with larger cohorts are required to validate these findings externally.

    Posttransplant lymphoproliferative disorder (PTLD) is a complication of solid organ transplantation and is associated with Epstein-Barr virus (EBV). Recently, EBV-related PTLD was defined as probable PTLD or proven PTLD. Probable PTLD involves significant lymphadenopathy, hepatosplenomegaly, or other end-organ manifestations, without a histological diagnosis, together with significant EBV DNAemia. Proven PTLD is the detection of EBV-encoded proteins in a tissue specimen, together with symptoms and/or signs originating from the affected organ. Probable PTLD after pediatric liver transplantation has not been well documented. Therefore, here, we aimed to describe cases of five pediatric patients with probable PTLD after liver transplantation, who were successfully treated with preemptive immunosuppression reduction with or without rituximab. All five patients (age range, 1-4 years; two girls and three boys) had EBV DNAemia. Three patients developed probable PTLD within 12 months of transplantation. Further, three patients had a significantly high EBV viral load, but the other two patients with lymphadenopathy and end-organ manifestation had a relatively low EBV viral load. Early onset pediatric PTLD with significant EBV DNAemia is almost universally EBV-related. Biopsy was not performed in any patient due to the relative inaccessibility of the lesion and young age of the patients. If the patient's symptoms are too mild, if excisional biopsy is too difficult to perform, or if the patient is too sick to undergo an invasive procedure, initiating preemptive treatment without a histological diagnosis could be the treatment option.

    BACKGROUND: Perihilar cholangiocarcinoma (pCCA) is often unresectable, because it includes crucial blood vessels in portal area. The prognosis of locally advanced unresectable cholangiocarcinomas is extremely poor. Recently, there have been several reports of the prognosis improving drastically with transplantation and combined chemoradiation therapy. However, liver transplantation for pCCA has 2 big problems. The first is that pCCA is located at a lethal position and its progress is sometimes rapid; therefore, the optimal timing of transplantation is sometimes lost. The second is vascular complications associated with neoadjuvant radiation, especially in living donor liver transplantation (LDLT). To overcome these problems, we performed conversion surgery using LDLT with simultaneous resection of the hepatic artery and portal vein, instead of neoadjuvant radiation. Herein, we report our experience of interposition reconstruction. METHODS: A 31-year-old man with primary sclerosing cholangitis (PSC) was diagnosed with locally advanced unresectable pCCA. The patient underwent radical chemotherapy (gemcitabine/cisplatin/S-1) and avoided radiation because of PSC. After 6 months, positron emission tomography-computed tomography revealed no lymph node metastasis. There was no time to wait. We immediately performed LDLT with simultaneous resection of hepatic artery and portal vein, and microsurgical reconstruction using auto-vessel grafts. RESULTS: The recipient recovered and was discharged 31 days posttransplant. His liver function improved, and he has had no recurrence after LDLT. CONCLUSION: LDLT with neoadjuvant radiation is associated with high risk of vascular complications. In some cases, conversion surgery after radical chemotherapy using good timing LDLT without radiation may increase chances of transplantation for locally advanced pCCA.

    BACKGROUND: Undifferentiated embryonal sarcoma of the liver (UESL) primarily occurs in children; it is rarely seen in adults and appears to have a poor prognosis. However, in recent years, some cases indicated that long-term survival was possible due to a combination of multiple surgeries, chemotherapy, and liver transplantation. CASE PRESENTATION: A 33-year-old female patient presented with a complaint of epigastric pain, for which she underwent a medical examination. Computed tomography (CT) and magnetic resonance imaging showed a cystic tumor in the right hepatic lobe, approximately 10 cm in size. During observation, the abdominal pain worsened, and a contrast-enhanced CT revealed that the tumor's peripheral solid components increased in size and volume, suggesting a malignant tumor threatening hepatic rupture. Subsequently, transcatheter arterial embolization of the anterior and posterior segmental branches of the hepatic artery was performed, followed by right trisectionectomy. Histopathological and immunohistochemical examinations of the lesion revealed UESL. Two months after the surgery, we initiated sarcoma-directed chemotherapy with doxorubicin because of multiple metastases to the liver. After initiating the chemotherapy, she received another regimen using gemcitabine/docetaxel, eribulin, trabectedin, ifosfamide/mesna, pazopanib, and cisplatin. During the chemotherapy, she underwent palliative surgery twice due to the progressive disease. She lived for 49 months after the initial operation. CONCLUSIONS: Improved long-term survival was achieved in an adult patient with UESL after multidisciplinary therapy, involving a combination of three surgical procedures and several chemotherapies.

    OBJECTIVE: Approximately 50 years have passed since the Kasai operation announcement for biliary atresia. In adult liver failure cases, the so-called "the carryover cases after Kasai operation" have increased. These patients often underwent polysurgery. In such cases, adult living-donor liver transplantation (LDLT) is occasionally difficult. Many complications have been reported to be caused by severe cholangitis, hepatic portal regional inflammation, and adhesion. We investigated the complications of adult LDLT in post-Kasai biliary atresia cases with polysurgery. METHODS: Between 1991 and 2021, we performed 205 LDLT cases. We investigated the outcome of adult LDLT for post-Kasai biliary atresia cases (transplanted over 16 years old) (n = 20) and the risk factors for complications after LDLT. RESULTS: On 5 years overall survival, there were no significant differences between "adult LDLT for post-Kasai" group and the others (81.8% vs 81.2%). Adult LDLT for post-Kasai was not found to be a risk factor for complications. However, polysurgery before LDLT was an independent risk factor for biliary stenosis and portal stenosis, as identified in our univariate and multivariate analysis. We analyzed the relationship between biliary stenosis and the frequency of laparotomies using a receiver operating characteristic curve. The analysis showed that the cutoff point (maximum point of sensitivity plus specificity) was more than 3 times that of laparotomies before LDLT. CONCLUSIONS: In our study, adult LDLT for post-Kasai cases was not a risk factor for any complications. However, polysurgery before LDLT has been identified as a risk factor for biliary stenosis and portal vein stenosis.

    BACKGROUND: Liver transplantation from donors after cardiac death (DCD) resolves donor shortages. PURPOSE: We investigated the optimal time for subnormothermic oxygenated perfusion in DCD liver transplantation. METHODS: Ten F1 pigs (body weight: 27-32 kg) were allocated to 2 groups: the heart beating group (n = 6), from which livers were retrieved while the heart was beating, and the donation after cardiac death (DCD) group (n = 4), in which liver retrieval was performed on pigs under apnea-induced cardiac arrest for 20 minutes. In both groups, the livers were kept in cold storage for 2 hours after retrieval and perfused with a subnormothermic oxygenated Krebs-Henseleit buffer for 120 minutes. We used a novel perfusion device, which can set maximum perfusion pressures of arteries and portal vein, developed by Asahikawa Medical University and Chuo Seiko Co. Bile production, liver enzymes, and inflammatory cytokines were measured and the sinusoidal space, using tissue specimens taken from liver grafts, was measured at 30, 60, 90, and 120 minutes after the start of perfusion. RESULTS: Bile production peaked at 90 minutes. Significantly higher levels of liver enzymes and inflammatory cytokines were found in the DCD group (P < .05). The release of liver enzymes peaked at 60 minutes and that of inflammatory cytokines peaked at 90 minutes. The hepatic sinusoidal space was wide at 90 minutes and narrowed after 120 minutes. CONCLUSIONS: The results suggest that subnormothermic oxygenation perfusion may maintain optimal graft condition until around 90 minutes and perfusion for more than 120 minutes may be counterproductive.

    Cholesterol granuloma is a benign, tumor-like lesion with an accumulation of cholesterol crystals in the tissue and is a consequence of a chronic inflammatory reaction. It commonly occurs in the middle ear but rarely in the liver. There is only one previous case report of cholesterol granuloma of the liver, which was caused by cholesterol hepatolithiasis. We report a case of cholesterol granuloma of the liver in a patient with no intrahepatic cholesterol stones; it was difficult to rule out malignant liver tumor preoperatively. The patient was a 79-year-old woman in whom a lesion in the liver was detected on abdominal ultrasonography. She was referred to our hospital for detailed examination and treatment. Abdominal contrast-enhanced computed tomography showed a 20 mm lesion with ring enhancement in the lateral segment of the liver during the arterial and delayed phases. Since a malignant tumor could not be ruled out radiologically, laparoscopic lateral segment hepatectomy was performed for definitive diagnosis and treatment. The resection specimen showed a yellowish-white lesion measuring 15 mm in diameter. Pathological examination showed a granulomatous lesion with cholesterol crystals surrounded by foreign body giant cells. The lesion was diagnosed as cholesterol granuloma of the liver. The postoperative course was good, and the patient was discharged on postoperative day 5. She was healthy, and no recurrence of the cholesterol granuloma was detected at the 5-month follow-up. This is the first case report of cholesterol granuloma of the liver mimicking a malignant liver tumor in a patient with no intrahepatic cholesterol stones.

    BACKGROUND: Machine perfusion of marginal kidney grafts obtained from donors after cardiac death (DCD) has become a standard therapy worldwide. However, the use of grafts from DCD due to long-term low blood pressure is associated with a high incidence of primary graft nonfunction. Furthermore, the importance of oxygenation in machine perfusion remains unclear. We report the first case of a clinical trial of a kidney transplant obtained from a DCD using a Japanese oxygenated hypothermic perfusion system (CMX-08W, Chuo Seiko Co Ltd, Asahikawa, Japan). PATIENTS AND METHODS: The donor was a 61-year-old man with amyotrophic lateral sclerosis. His SpO2 decreased to 80% to 90%, his blood pressure remained consistently low for 4 hours and 30 minutes, and he suffered a cardiac arrest. Subsequently, we carried him to the operating room. The warm ischemic time was 12 minutes, and the cold ischemic time was 418 minutes. The recipient was a 58-year-old man who had been undergoing hemodialysis for 26 years. He was diagnosed with nephrosclerosis and multiple renal cysts. Oxygenated hypothermic machine perfusion was used on the kidney transplant obtained from the DCD. RESULTS: The recipient gradually recovered and was withdrawn from hemodialysis therapy 14 days post transplantation. His renal function improved, and he was discharged on postoperative day 36. Currently, his renal function remains good (phosphocreatine, 1.7). CONCLUSIONS: Oxygenated machine perfusion is used to preserve organs and determine if an organ is suitable for transplantation. This may provide the possibility of perfusion preservation and expand the criteria for cardiac arrest-associated renal transplantation.

    BACKGROUND: The number of brain-dead donors has been increasing; however, the opportunity for young surgeons to experience deceased donor surgeries is extremely limited, especially in many Asian countries including Japan. Deceased donor surgeries require unique surgical skills and knowledge; however, it is difficult to provide on-the-job guidance and education. Therefore, cadaver training is meaningful and suitable for the training of deceased donor surgeries. Thiel's embalming method (TEM) provides natural coloration, flexibility, and tissue plasticity, and is widely used for cadaver surgical training. In this study, we evaluated the usefulness of Thiel's embalmed cadaver training for organ procurement surgery. MATERIAL AND METHODS: Each trainee performed hepatectomy, pancreatectomy, and nephrectomy using conventional open techniques. Faculty experts of transplantation surgery and organ procurement took attendees through surgical steps. After the procedure, all participants were asked to complete a voluntary, anonymous survey, consisting of a 10-point satisfaction scale, to evaluate their perceptions of the training. RESULTS: A total of 33 gastrointestinal surgeons participated in the training program for procuring the liver, pancreas, and kidneys. In the questionnaire administered to the participants, the evaluation was generally satisfactory, with an average of 9.1 points on the 10-point scales. Some participants expressed that Thiel-embalmed cadavers are more suitable for training on organ procurement compared with animals used in wet-lab training. CONCLUSION: We conclude that organ procurement training in human cadavers preserved by TEM is useful and suitable for practicing deceased donor organ procurement, especially in countries where deceased donors are not common, as in Japan.

    INTRODUCTION: Patients with end-stage liver disease often have cardiac dysfunction, which can be worsened by hemodynamic instability in liver transplantation, causing congestive graft injury. PRESENTATION OF CASE: A 28-year-old male with Wilson's disease underwent liver transplantation. The patient's history included cirrhotic cardiomyopathy and a preoperative ejection fraction of 37% on echocardiography. After liver transplantation, massive transfusion and acute renal failure led to increased central venous pressure. Doppler ultrasonography (US) showed an increase in positive components of the hepatic vein triphasic wave, followed by pulsatile changes in the portal vein waveforms and an eventual to-and-fro pattern. Laboratory data showed severe elevations of hepatocellular transaminase levels. Based on Doppler US findings, we determined liver damage was due to passive congestion caused by heart failure. Immediate initiation of continuous hemodiafiltration (CHDF) and intra-aortic balloon pumping (IABP) led to the patient's recovery from severe heart failure and graft injury. DISCUSSION: In our case, changes in the hepatic and portal vein waveforms and marked elevation of hepatocellular transaminases implied exacerbation of heart failure caused by hepatic congestion and injury. Worsening heart failure, in turn, led to progressive liver damage as the result of hepatic passive congestion. The patient's condition was successfully managed with early initiation of CHDF and IABP. CONCLUSION: Doppler US can help diagnose congestive graft injury due to heart failure in liver transplant patients and should be performed during post-transplant management of patients with cardiac dysfunction.

    BACKGROUND: Endoscopic and PTB interventions are common nonsurgical interventions for biliary anastomotic strictures that occur after liver transplantation. When these nonsurgical interventions fail, surgical re-anastomosis is considered; however, this is quite invasive and can cause additional injury that may lead to graft loss. We report a case in which conventional nonsurgical interventions failed, but a new method that involve the use of a transseptal needle-a device to create a transseptal left-heart access during cardiac catheter interventions-was successfully used in recanalization of the hepaticojejunal anastomotic obstruction. CASE: A 21-year-old man, who had received living-donor liver transplantation for biliary atresia at the age of 23 months presented with recurrent cholangitis and liver dysfunction due to a biliary anastomotic stricture of the hepaticojejunostomy. Therapeutic interventions for biliary stricture, including the PTB approach, double-balloon enteroscopic approach, and rendezvous approach failed. We then performed needle puncture of the anastomotic obstruction using a transseptal needle and succeeded in recanalizing the complete anastomotic obstruction. To perform the procedures safely, we evaluated the organ and needle positions using biplane fluoroscopy and placed a balloon in the afferent jejunal limb as a target for puncture. The 12 Fr catheter via the biliary route was removed 7 months after the procedure, without using a catheter, there was no recurrent stricture or cholangitis for 26 months. CONCLUSION: Using a transseptal needle to manage hepaticojejunal anastomotic obstruction can reduce the number of patients who need surgical re-anastomosis.

    BACKGROUND: In living donor liver transplantation (LDLT) for patients with Budd‒Chiari syndrome (BCS), there are several concerns about reconstruction of the inferior vena cava (IVC) and hepatic veins. Herein, we report the case of a patient with BCS who underwent LDLT with right posterior segment graft (RPSG) and patch plasty for reconstruction of the hepatic venous outflow, using the patient's own superficial femoral vein (SFV). CASE PRESENTATION: A 19-year-old man, who was diagnosed with primary BCS, underwent LDLT. His main hepatic veins were totally obstructed, and membranous stenosis was seen in the IVC. The LDLT donor was his mother; however, liver volumetric analysis showed that only her RPSG was appropriate. In the recipient surgery, 16 cm of the left SFV was harvested and was cut longitudinally and opened. The right hepatic vein (RHV) of the RPSG was anastomosed to the sidewall of the SFV graft. After explantation of native diseased liver was completed, the stenotic and thickened wall of the IVC was widely resected, and a large anastomotic orifice was created. Patch cavoplasty was performed with the RHV‒SFV graft patch. After portal reperfusion started, hepatic venous outflow was satisfactory, and there was no venous graft congestion. Both his postoperative course and his long-term course after discharge were uneventful. CONCLUSIONS: In LDLT for BCS patients, ingenuity is required for the reconstruction of venous outflow. The SFV patch can be safely harvested from liver transplant recipients and is suitable for venous reconstruction. In addition, RPSG is an alternative type of liver graft for LDLT if a conventional right- or left-lobe graft cannot be used.

    Laparoscopic fenestration (LF) has recently been considered a standard procedure for nonparasitic symptomatic liver cysts. Here, we report a case of LF that was safely performed using real-time indocyanine green (ICG) fluorescence-guided surgery. A 74-year-old woman presented with right upper abdominal pain and poor dietary intake. The patient was diagnosed with symptomatic liver cysts and underwent LF. One hour before surgery, ICG (2.5 mg) was intravenously administered to the patient. ICG fluorescence imaging clearly showed the biliary ducts and distinguished the cysts from the liver parenchyma. We could resect only the cyst walls as wide as possible under the guidance of both white light and fluorescence imaging. There were no signs of postoperative symptom recurrence. Detection of ICG fluorescence in the liver parenchyma is as important as ICG cholangiography for fenestration. Laparoscopic liver cyst fenestration with real-time ICG fluorescence-guided surgery is safe and can be used as a standard procedure.

    BACKGROUND: Renoportal anastomosis is an option for the portal vein reconstruction of a liver transplantation with grade 4 portal vein thrombosis and a splenorenal shunt. Here, we report the case of gastrointestinal bleeding who underwent living donor liver transplantation (LDLT) with renoportal anastomosis. CASE PRESENTATION: Six-year-old female patient who underwent LDLT with renoportal anastomosis at 1 year of age had severe anemia with normal liver function during the follow-up period. The varices at the Roux-en-Y jejunum were considered the source of bleeding, and the compression of the left renal vein, which is known as a cause of Nutcracker syndrome, seemed to induce venous hypertension through the splenorenal shunt, which might induce the formation of the varices. She underwent percutaneous transhepatic sclerotherapy of the varices, and the anemia improved at her last follow-up, 6 months after sclerotherapy. This is the first reported case of Roux-en-Y jejunal varices bleeding related to the compression of the left renal vein after LDLT was performed with renoportal anastomosis. CONCLUSIONS: Although renoportal anastomosis should be cautiously performed when there are no options for severe portal vein thrombosis, the status of the left renal vein and new collateral formation should be observed carefully during the follow-up period in pediatric cases of renoportal anastomosis.

    Background: The human intestine is the site of absorption and first-pass metabolism for oral intake. Assessment of absorption, distribution, metabolism, excretion, and toxicity (ADMET) of xenobiotics has transformed the understanding of in vivo pharmacology. However, these processes are difficult torecapitulate in vitro. Objective: We have developed a simple protocol for the generation of mature functional intestinal organoids from human pluripotent stem cells (hPSCs)under xenogeneic-free conditions. We sought to characterize transcription level in drug transporters and metabolism and evaluate CYP3A4 catalytic function of the organoids. Methods: Human pluripotent stem cell-derived intestinal organoids were generated and evaluated the expression of drug transporters and metabolizing enzymes. We examined the induction of CYP3A4 and ABCB1 gene expression in the organoids. Furthermore, we analyzed the CYP3A4 enzyme activity of the organoids by the p450-Glo CYP3A4 assay kit with luciferin isopropyl acetal. Results: Stem cell-derived intestinal organoids had an outward polarized intestinal epithelial layer and showed similar expression levels of drug transporters and metabolism genes as the adult healthy intestine. They also exhibited CYP3A4 enzymatic function in vitro. Conclusion: This model provides a novel platform for pharmacological testing and can enhance human ADMET studies in drug development.

    Purpose: Enhanced recovery after surgery (ERAS) is beneficial to patients undergoing digestive surgery. However, its efficacy in patients undergoing open hepatectomy remains unclear. Methods: Consecutive patients scheduled for open hepatectomy were randomly assigned to undergo either ERAS or conventional postoperative management. The primary endpoint was the amount of time that elapsed before patients were considered medically fit for discharge (MFD) and length of hospital stay (LOHS). Secondary endpoints included morbidity, mortality, the time to first flatus, defecation, first walk, and freedom from infusion. Perioperative serum nutritional markers, insulin resistance, respiratory quotient (RQ), and resting energy expenditure (REE) were also assessed. Results: Between August 2014 and March 2017, 57 patients were randomized into 2 groups; ERAS group (n = 29) and conventional management (n = 28). The median MFD was not significantly different between the ERAS and conventional management groups (6.5 vs. 7 days; P = 0.381). Recovery from gastrointestinal paresis was significantly quicker in the ERAS group (1.8 vs. 2.4 days; P = 0.004). There were no significant differences in serum markers, insulin resistance, RQ, and REE. Conclusion: This trial did not demonstrate greater efficacy of the ERAS protocol following open hepatectomy in terms of the MFD and LOHS. However, the ERAS protocol was associated with better recovery from postoperative gastrointestinal paresis, suggesting that it is useful for patients undergoing open hepatectomy.

    Desensitization with RTX has been broadly introduced in adult LT across the ABO blood type barrier. For pediatric LT, the prophylactic use of RTX has not been standardized, especially for children under 2 years of age. A 20-month-old girl with BA underwent living donor LT from her ABO-I mother. On POD 6, she developed combined T cell-mediated and AMRs. Steroid bolus injection was immediately introduced, followed by antibody-depleting therapy with PE and IVIG. Based on a peripheral blood lymphocyte analysis by fluorescence-activated cell sorting, ATG and RTX were introduced for refractory rejection. Although she recovered from the combined rejections, IHBCs were inevitable as a consequence. We recommend extending the desensitization protocol to cover children under 2 years of age in order to prevent life-threatening complications.

    BACKGROUND: Despite reported associations between intrapulmonary vascular shunting (IPVS) and morbidity and mortality in pediatric liver transplantation (LT), there are no guidelines for screening. OBJECTIVE: To investigate IPVS before and after pediatric LT. METHODS: Retrospective records review of all pediatric LT (n = 370) from 2005 to 2015 at a single institute in Japan. All children with cirrhosis and clinical suspicion of IPVS without cardiac or pulmonary conditions were included. 99mTechnetium labelled macroaggregated albumin (99mTcMAA) scans were performed before and after LT. The severity of IPVS was graded using shunt ratios. RESULTS: Twenty-four children fulfilled inclusion criteria and underwent Tc99MAA scans. All revealed mild (<20%) to moderate (20%-40%) grades of IPVS. Following LT, the mean shunt ratio regressed from 20.69 ± 6.26% to 15.1 ± 3.4% (P = .06). The median (range) follow-up was 17 (4-85) months. Mortality was zero. The incidence of portal vein thrombosis (4.2%) biliary strictures (12.5%) and graft loss (4.1%) in the study group was not statistically significant compared to the remainder of the 370 transplants (3.2%, 9.4% and 3%, respectively). Sub-group analysis revealed hepatopulmonary syndrome (HPS) in 2 out of 24 children. The mean shunt ratios before and after LT were 39.2 ± 0.77% and 16.2 ± 8.5%, respectively (P = .08). There was 1 complication (intra-abdominal abscess). CONCLUSIONS: HPS is less likely in mild to moderate IPVS. LT may achieve comparable results when performed in the presence of mild to moderate IPVS.

    BACKGROUND: Excellent outcomes of the extreme procedure of liver resection (LR) for advanced hepatoblastoma (HB) have been achieved in recent reports. However, liver transplantation (LT) remains the only surgical treatment for patients with unresectable HB. The aim of this study was to evaluate our retrospective data for cases of advanced HB necessitating surgical intervention and analyze the prognostic factors of recurrence by comparing patients with tumors resected by LR and LT. PATIENTS AND METHODS: We retrospectively reviewed 24 children with PRETEXT II/III/IV tumors that required consideration for LT between August 2011 and September 2016. RESULT: The staging at the time of the diagnosis was PRETEXT II/III/IV in 1/13/10 patients, respectively, while the preoperative staging after neoadjuvant chemotherapy was POSTTEXT II/III/IV in 5/17/2 patients. Among those 24 patients, complete resection of the primary tumor was achieved with LT in 12 patients and LR in 12 patients. A high serum level of alpha-fetoprotein (AFP) at the time of surgery, no significant decrease in the rate of change of AFP, and low tumor shrinkage rate were related to the risk of tumor recurrence, and patients with tumors resected by LR with those risks had a higher recurrence rate than those without them. The overall survival was higher in patients with tumors resected by LT (100%) than in patients with tumors resected by LR. CONCLUSION: Patients with advanced HB with a poor response to chemotherapy should definitively be prioritized for primary LT, given the possibility of vascular invasion and microscopic residual tumor.

    PV hypoplasia may increase the risk of posttransplant complications, especially when it extends to near the SMV and SpV junction. We described our experience of 10 pediatric cases of PV hypoplasia/thrombus in which the pullout technique was required for PV reconstruction. There were five male and five female patients. The median age was 9 months, and the median weight was 8.1 kg. The indications for the pullout technique were PV hypoplasia in seven patients and PV thrombus in 3. The inflow sites of the enlarged LGV were as follows: the main PV trunk (n = 2), the SMV and SpV junction (n = 4), and the SpV (n = 4). The posterior face of the pancreas was tunneled along the PV, and the PV was returned to its original position with or without the use of an interposed vein graft. The pullout technique created a good operative field, which allowed for the complete removal of the hypoplastic PV or thrombectomy with the safe use of various interposed vein grafts.

    Reducing graft thickness is essential to prevent large-for-size graft problems in pediatric living donor liver transplantation (LDLT). However, long-term outcomes of LDLT using reduced-thickness left lateral segment (LLS) grafts are unclear. In 89 patients who underwent LDLT using reduced LLS grafts between 2005 and 2017, short-term and long-term outcomes were compared between a nonanatomically reduced LLS (NAR-LLS) graft group and a reduced-thickness LLS graft group. Estimated blood loss was lower and abdominal skin closure was less needed in the recipient operation in the reduced-thickness LLS graft group. Postoperatively, portal vein (PV) flow was significantly decreased in the NAR-LLS graft group, and there was shorter intensive care unit (ICU) stay and fewer postoperative complications, especially bacteremia, in the reduced-thickness LLS graft group. Graft survival at 1 and 3 years after LDLT using reduced-thickness LLS grafts was 95.2% and 92.4%, respectively, which was significantly better than for NAR-LLS grafts. Multivariate analysis revealed that fulminant liver failure, hepatofugal PV flow before LDLT, and NAR-LLS graft were associated with poor graft survival. In conclusion, LDLT using reduced-thickness LLS grafts is a safe and feasible option with better short- and long-term outcomes in comparison with NAR-LLS grafts.

    HVOO can be a critical complication in pediatric LDLT. The aim of this study was to evaluate a modified triangular technique of hepatic vein reconstruction for preventing HVOO in pediatric LDLT. A total of 298 pediatric LDLTs were performed using a left lateral segment graft by 2 methods for reconstruction of the hepatic vein. In 177 recipients, slit-shaped anastomosis was indicated with partial clamp of the IVC. A total of 121 recipients subjected to the modified triangular anastomosis with total clamp of the IVC. We compared the incidence of hepatic vein anastomotic complications between these 2 methods. Nine of the 177 cases (5.3%) treated with the conventional technique were diagnosed with outflow obstruction. All 9 cases underwent hepatic vein reconstruction with the slit-shaped hepatic vein anastomosis. In contrast, there were no cases of outflow obstruction in the 121 cases treated with the modified triangular anastomosis. The modified triangular technique of hepatic vein reconstruction with total clamping of the IVC was useful for preventing HVOO in pediatric LDLT.

    The shortage of deceased organs is still a serious issue in Japan. A proactive approach to using liver grafts from extended criteria donors (ECDs) may be one way of expanding the donor pool; however, if it is recklessly attempted, a recipient receiving such a marginal graft can be at risk of mortality due to primary non-function or delayed graft function. We herein report the successful outcome of a recipient receiving a severely cholestatic graft that was considered transplantable because it lacked features characteristic of a long duration of "cholestasis" according to the precise interpretation of a donor biopsy. Plasma exchange was intentionally introduced to prevent toxic insult by hyperbilirubinemia immediately after transplant. Despite transient acute kidney injury immediately after transplant, the patient's renal impairment was well managed with a renal-sparing immunosuppressive regimen consisting of basiliximab and mycophenolate mofetil. Although the use of liver grafts from ECDs still needs to be discussed, especially regarding graft selection and allocation policies, efforts not to discard valuable grafts should be undertaken in our country.

    NEC is an idiopathic intestinal mucosal injury that may progress to transmural bowel necrosis without mesenteric ischemia. NEC usually affects 7- to 10-day-old neonates following enteral feeding. A 10-month-old girl with no history of laparotomy underwent LDLT for acute liver failure. After starting enteral feeding on postoperative day 5, she developed abdominal distention. Diffuse PVG and PI were detected by radiologic modalities. Exploratory laparotomy revealed patchy necrosis of the intestine without perforation. The microscopic findings of a resected specimen revealed transmural coagulative necrosis with multiple small thromboses compatible with neonatal NEC features, and eosinophil infiltration was also observed. Subsequently, after the resumption of enteral feeding with cow's milk, she developed severe diarrhea, the symptoms of which were eliminated after the administration of cow's milk was stopped. These clinical and pathological findings support the speculation that NEC might have been induced by a CMA. Food allergies, which can be induced by immunosuppressive agents, should be considered as a potential cause of NEC in the setting of pediatric liver transplantation.

    The patient was a boy of 7 years and 5 months of age, who underwent LDLT for acute liver failure at 10 months of age. HV stent placement was performed 8 months after LDLT because of intractable HV stenosis. At 7 years of age, his liver function deteriorated due to chronic rejection. The patient therefore underwent living donor liver retransplantation from his father. The HV was transected with the stent in situ. The IVC was resected due to stenosis. The pericardial cavity was opened and detached around the IVC to elongate the IVC. The divided ends of the IVC were joined by suturing to the posterior wall of the IVC. A new triangular orifice was made by adding an incision on the anterior wall of the IVC. The graft HV was then anastomosed to the new orifice with continuous sutures in the posterior wall and interrupted sutures in the anterior wall using 5-0 non-absorbable sutures. Doppler ultrasound showed a triphasic waveform. We successfully performed HV reconstruction without a vascular graft. This is a feasible procedure for overcoming HV stenosis in LDLT patients with an indwelling stent.

    AIM: Our aim was to analyze serial changes in the predictive variables and a scoring system retrospectively adapted to evaluate outcomes in pediatric patients with acute liver failure (ALF). METHODS: We retrospectively collected data on 65 patients with ALF. The 65 patients were divided into two groups according to the need for liver transplantation (LT) as follows: LT group (n = 54) and non-LT group (n = 11). The early determination scoring system of the indications for LT proposed by the Intractable Hepato-Biliary Diseases Study Group of Japan (JIHBDSG) was used in our study. The area under the receiver operating characteristic curve (AUROC) was calculated for the JIHBDSG score between the LT group and non-LT group at the time of diagnosis (day 0) and day 3, and day 5 after the diagnosis. RESULTS: A JIHBDSG score of >3 at day 5 was found to identify the patients requiring LT with 83.7% sensitivity, 81.8% specificity, and 83.3% diagnostic accuracy. Based on a comparison of AUROC values, the JIHBDSG score on day 5 (AUROC 0.91) was higher than that on day 0 (AUROC 0.75) and day 3 (AUROC 0.84). CONCLUSION: We showed that a serial analysis of the JIHBDSG score might be useful for predicting outcomes of ALF in pediatric patients who fulfilled the criteria of LT indication in our center. However, further studies are needed to validate our results.

    After decades of dramatic surgical innovations in pediatric living donor liver transplantation (LDLT), LDLT for biliary atresia (BA) still poses various challenges. This study reviewed our experience with LDLT for children with post-Kasai BA and evaluated outcomes and prognostic factors. From 2005 to 2016, 168 post-Kasai BA LDLT patients were enrolled and divided into 3 groups by age. Patient characteristics and perioperative data were compared. Predictors of morbidity and mortality following LDLT were analyzed in 93 infants. Outcome was relatively worse in infants than older children, with overall survival at 1 and 5 years of 94.5% and 93.2%, respectively, and graft survival at 1 and 5 years of 91.1% each. Incidence of vascular complications was not significantly higher in infants. High Pediatric End-Stage Liver Disease (PELD) score (odds ratio [OR], 3.72; 95% confidence interval [CI], 1.30-10.67; P = 0.02) and portal vein (PV) hypoplasia (OR, 3.23; 95% CI, 1.10-9.52; P = 0.03) were independent risk factors for morbidity. Low weight-for-age z score (hazard ratio, 5.76; 95% CI, 1.05-31.47; P = 0.03) was identified as a significant risk factor for mortality after LDLT, but not age or absolute body weight (BW). Infants with BW deficit had a significantly smaller PV diameter (P = 0.005), greater blood loss (P = 0.001), and higher incidence of postoperative bacteremia (P = 0.01). In conclusion, high PELD score and PV hypoplasia were independent risk factors for morbidity, and BW deficit was associated with poor survival in infants with post-Kasai BA after LDLT. However, LDLT in these infants at the earliest possible time after referral is a feasible option with excellent patient survival in an experienced center.

    Living donor liver transplantation (LDLT) is now an established technique for treating children with end-stage liver disease. Few data exist about liver transplantation (LT) for exclusively young infants, especially infants of <3 months of age. We report our single-center experience with 12 patients in which LDLT was performed during the first 3 months of life and compare the results with those of older infants who underwent LT. All of the patients were treated at the National Center of Child Health and Development, Tokyo, Japan. Between November 2005 to November 2016, 436 children underwent LT. Twelve of these patients underwent LT in the first 3 months of life (median age, 41 days; median weight, 4.0 kg). The indications for transplantation were fulminant hepatic failure (n = 11) and metabolic liver disease (n = 1). All the patients received the left lateral segment (LLS) in situ to mitigate the problem of graft-to-recipient size discrepancy. A reduced LLS graft was used in 11 patients and a segment 2 monosegment graft was used in 1 patient. We compared the results with those of infants who were 4-6 months of age (n = 67) and 7-12 months of age (n = 110) who were treated in the same study period. There were significant differences in the Pediatric End-Stage Liver Disease score and the conversion rate of tacrolimus to cyclosporine in younger infants. Furthermore, the incidence of biliary complications, bloodstream infection, and cytomegalovirus infection tended to be higher, whereas the incidence of acute cellular rejection tended to be lower in younger infants. The overall cumulative 10-year patient and graft survival rates in recipients of <3 months of age were both 90.9%. LDLT during the first 3 months of life appears to be a feasible option with excellent patient and graft survival. Liver Transplantation 23 1051-1057 2017 AASLD.

    Children with ESRD in need of RRT are commonly managed by PD due to difficulty with vascular access for HD and the relatively large extracorporeal blood volume required. Major abdominal surgery may result in injury to the peritoneum and consequent adhesion, thereby resulting in a reduction in the anatomical capacity and transport capability across the peritoneal membrane. Here, we report successful resumption of PD after LDLT in two pediatric patients. The causes of ESRD were PH1 and juvenile nephronophthisis, respectively. Both patients were managed by PD prior to LDLT. PD was converted to HD starting three days before LDLT and was continued postoperatively until resumption of PD on days 13 and 28, respectively. The PD weekly Kt/V urea was maintained before and after LDLT. The patients continued to do well on PD without complications. Meticulous intra-operative techniques during LDLT allow postoperative PD resumption by preservation of peritoneal integrity with effective transport capability and without added risk of peritonitis.

    Ornithine transcarbamylase deficiency (OTCD) is a urea cycle disorder of X-linked inheritance, affecting the detoxification of excess nitrogen and leading to hyperammonemia (hyper-NH3 ). Living donor liver transplantation (LDLT) has been applied for the treatment of OTCD. This case series retrospectively reviewed two OTCD patients who experienced hyper-NH3 following LDLT. The first case was a 5-year-old girl who had onset of OTCD at 2 years of age. Ornithine transcarbamylase (OTC) enzyme activity was 62% for the donor and 15% for the recipient. The patient suffered from recurrence of hyper-NH3 within 2 months following LDLT. The second case was a 5-year-old girl who had onset of OTCD at 3 years of age. OTC enzyme activity was 42.6% for the donor and 9.7% for the recipient. The patient suffered hyper-NH3 for 12 days starting on the date of surgery. Both of the patients transiently required continuous veno-venous hemodialysis; however, they are currently doing well without intensive medical treatment. The use of asymptomatic OTCD heterozygous donors in LDLT has been accepted with careful examination. However, an OTCD heterozygous carrier donor should be avoided if there is another donor candidate, due to the potentially fatal condition of hyper-NH3 following LDLT.

    Functional intestines are composed of cell types from all 3 primary germ layers and are generated through a highly orchestrated and serial developmental process. Directed differentiation of human pluripotent stem cells (hPSCs) has been shown to yield gut-specific cell types; however, these structures do not reproduce critical functional interactions between cell types of different germ layers. Here, we developed a simple protocol for the generation of mature functional intestinal organoids from hPSCs under xenogeneic-free conditions. The stem cell-derived gut organoids produced here were found to contain distinct types of intestinal cells, including enterocytes, goblet cells, Paneth cells, and enteroendocrine cells, that were derived from all 3 germ layers; moreover, they demonstrated intestinal functions, including peptide absorption, and showed innervated bowel movements in response to stimulation with histamine and anticholinergic drugs. Importantly, the gut organoids obtained using this xenogeneic-free system could be stably maintained in culture for prolonged periods and were successfully engrafted in vivo. Our xenogeneic-free approach for generating gut organoids from hPSCs provides a platform for studying human intestinal diseases and for pharmacological testing.

    BACKGROUND: Hepatoblastoma (HB) is a highly malignant primary liver tumor in children. Although liver transplantation (LT) is an effective treatment for unresectable HB with good long-term outcomes, post-transplant survival is mainly affected by recurrence, despite adjuvant chemotherapy. Novel strategies are needed to improve the outcomes in patients undergoing LT for unresectable HB. PATIENTS AND METHODS: Twelve children received LT for unresectable HB. In 9 patients, we applied early exclusion of hepatic inflow (hepatic artery and portal vein) and creation of a temporary portocaval shunt during LT. RESULT: There were differences in the duration of and the blood loss during operation as compared with previously reports. The estimated glomerular filtration rate was well preserved at 3, 6, and 12months and the latest follow-up after LT, and the recurrence-free survival was 88.9%. CONCLUSION: Early inflow control during LT for unresectable HB may benefit recurrence-free survival by minimizing blood loss and tumor dissemination, preserving renal function and allowing early adjuvant chemotherapy.

    As the priority of LD-Domino LT is the safety of the first recipient, limitations and technical difficulties in the second recipient often occur. The most technically challenging part of LD-Domino LT is the reconstruction of the vessels. For the reconstruction of HVs, the native HVs were exteriorized as far as possible using a CUSA because longer extensive HVs are essential for facilitating the reconstruction. At the back table, the HVs of the domino graft were sutured together, and the single cuff of the HVs was anastomosed to the IVC by joining the orifices. The HAs, the presence of insufficient length, and multiple vessels in the whole liver rendered the reconstruction more difficult. We determined the dividing sites of the vessels according to the preoperative 3D-CT findings obtained in two institutions. This is the first case series using grafts in DLT obtained from LDLT for patients with MSUD between two institutions. In conclusion, LD-Domino LT is a safe and feasible therapeutic option to expand the donor pool by technical refinement in the reconstruction of the second recipient. Further studies with a greater accumulation of patients and a longer follow-up will be necessary to establish LD-Domino LT using an MSUD donor.

    LT from ABO-I donors requires preconditioning regimens to prevent postoperative catastrophic AMR. NAC for HBL is known to cause myelosuppression leading to a reduction in the number and function of lymphocytes. We investigated this chemotherapy-induced myelosuppression in HBL patients listed for LT from ABO-I donors with reference to the kinetics of B, T cells, and anti-ABO blood type isoagglutinin titers. Between 2005 and 2015, of the 319 patients who underwent LDLT at our institute, 12 were indicated for unresectable HBL. Three patients with unresectable HBL who underwent LDLT from ABO-I donors are included in this study. Immunosuppression consisted of a standard regime of tacrolimus and low-dose steroids as in ABO compatible/identical LDLT. No additional preoperative therapies for B-cell depletion were used. Absolute lymphocyte counts, lymphocyte subsets (including CD20+ B cells, CD3+CD4+ T cells and CD3+CD8+ T cells), and anti-ABO blood type isoagglutinin titers were measured before LDLT and postoperatively. The median age at diagnosis was 19 months (range, 3-31 months). The median follow-up was seven months (range, 6-15 months). The median interval from the last NAC to LDLT was 33 days (range, 25-52 days). The median interval from LDLT to adjuvant chemotherapy was 28 days (range, 22-36 days). The counts of CD20+ B cells before LDLT were depleted to median 5 cells/mm(3) (range, 0-6 cells/mm(3)). There was a transient rebound in the CD20+ B cell counts on day seven (maximum of 82 cells/mm(3)) followed by a decline starting at 14 days after LDLT that was sustained for the duration of adjuvant chemotherapy. Anti-ABO blood type isoagglutinin titers were lowered to between 1:1 and 1:16 before LDLT and remained low for the duration of follow-up in this study. All of the three patients remained in good health without either acute cellular or AMR after LDLT. The B-cell depletion that occurs after cisplatin-based chemotherapy for HBL may help accomplish safe ABO-I LDLT in children without the use of additional conditioning regimens for prevention of AMR.

    The management of LSRS is a crucial problem to ensure a sufficient PV flow during pediatric LT. Although several techniques have been indicated to solve this problem, a more appropriate approach to LSRS is still needed in pediatric LT. We herein present a modified surgical approach to the ligation of LSRS via the left side of the IVC for a nine-month-old boy with severe portal hypertension and a history of Kasai portoenterostomy. LSRS was identified and exposed through the left side of the IVC and the dorsal surface of the pancreas from the superior side of the body of the pancreas. The post-operative course was uneventful with an excellent PV flow. The central approach for the ligation of LSRS is worth considering as an alternative procedure for a patient with collateral vessels and a history of multiple laparotomies.

    PC is produced in the liver and inhibits blood coagulation by catalyzing active factors V and VIII. PC deficiency causes abnormal blood clotting that is difficult to regulate by anticoagulative treatments. Four reports of PC deficiency treated with LTx have been published; however, no report of DLT as a therapy for PC deficiency is available. We describe a case of a 23-month-old girl who received DLT for compound heterozygous PC deficiency. Her PC activity was below 5%. She developed intracranial lesion and frequent refractory purpura fulminans. Both her parents had heterozygous mutations of PC genes and were excluded as living donors. Furthermore, she was a low priority on the waiting list of deceased-donor transplantation. We performed living DLT using the liver from a patient with MSUD. Activated PC concentrate safely supported the perioperative period. After DLT, she maintained normal PC activities and BCAA levels. This is the first case of PC deficiency successfully treated by living DLT with MSUD. We propose that DLT using liver from patients with MSUD is a treatment option for PC deficiency.

    BACKGROUND/PURPOSE: Acoustic radiation focus impulse (ARFI) elastography is a new method for assessing the degree of tissue stiffness. We herein evaluated the degree of spleen stiffness (SS) using ARFI elastography in patients with biliary atresia (BA) after Kasai portoenterostomy (KPE). METHODS: We retrospectively collected the liver stiffness (LS) and SS values on ARFI elastography from 43 patients undergoing KPE between September 2010 and November 2013. We analyzed the correlations between these values and variables related to the severity of liver dysfunction and portal hypertension (PHT). The data were expressed as the standard deviation score (z-score) relative to the previously reported normal values for the patient's age. RESULTS: The SS value was significantly associated with the spleen diameter and development of collateral vessels, in comparison to the LS value. Interestingly, there was a significant correlation between SS value and the portal vein (PV) diameter. Thirty patients (69.8%) consequently underwent LT; these patients showed higher SS values and smaller PV diameters than the patients monitored without LT. CONCLUSIONS: The degree of SS measured on ARFI elastography can be used to predict the severity of PHT in BA patients after KPE.

    The immune function (ImmuKnow) assay is a measure of cell-mediated immunity based on the peripheral CD4+ T cell ATP activity. The efficacy of ImmuKnow in pediatric LDLT is not well documented. The aim of this study was to assess the correlations between the ImmuKnow and the clinical status in pediatric LDLT recipients. A total of 716 blood samples were obtained from 60 pediatric LDLT recipients (one month to 16 yr of age). The recipient's status was classified as follows: stable, infection, or rejection. The ImmuKnow values in the pediatric LDLT recipients with a clinically stable status had a lower immune response (IQR 85-297 ATP ng/mL) than that previously reported in adults. Meanwhile, the ImmuKnow values of the stable patients were not correlated with age. Furthermore, a significant difference was found in the ImmuKnow values between the bacterial or fungal infection and stable groups, but not between the CMV or EBV infection and stable groups. The ImmuKnow levels in the pediatric LDLT were lower than those observed in the adult LDLT. The proposed reference value is between 85 and 297 ATP ng/mL in pediatric LDLT recipients. We conclude that the ImmuKnow assay could be helpful for monitoring pediatric LDLT recipients with bacterial or fungal infections.

    Several transplant strategies for PH1 have been proposed, and LT is performed to correct the metabolic defects. The patients with PH1 often suffer from ESRD and require simultaneous LKT, which leads to a long wait due to the shortage of suitable organ donors. Five patients with PH1 underwent LDLT at our institute. Three of the five patients were under dialysis before LDLT, while the other two patients were categorized as CKD stage 3. An isolated LDLT was successfully performed in all but our first case, who had complicated postoperative courses and consequently died due to sepsis after retransplantation. The renal function of the patients with CKD stage 3 was preserved after LDLT. On the other hand, our second case with ESRD underwent successful LDKT six months after LDLT, and our infant case is waiting for the subsequent KT without any post-LDLT complications after the early establishment of PD. In conclusion, a two-step transplant strategy may be needed as a life-saving option for patients with PH1 and may be possible even in small infants with systemic oxalosis. While waiting for a subsequent KT, an early resumption of PD should be considered from the perspective of the long-term requirement of RRT.

    Hepatocyte transplantation (HT) is attractive option for urea cycle disorder and acute liver failure. HT has the benefit of non-invasive treatment, availability of hepatocyte isolated from marginal donors and cryopreserved hepatocytes at the time of need. On the other hand, the disadvantages of HT are injury of hepatocytes after thawing, difficulty of monitoring acute cellular rejection after HT, and limited donor source for HT. We experienced HT for neonatal ornithine transcarbamylase deficiency patient using hepatocytes from living donor for the fi rst case in the world. In our study, hepatocytes were isolated from the redundant liver of reduced left lateral segment graft from living donor. The quality of hepatocytes from living donor is better than that from deceased donor. The patient underwent living donor liver transplantation from his mother 5 months after HT.

    We present a case of a two-yr-old boy diagnosed with HBT with complete main PVTT. HBT was located in the bilateral lobe with PVTT involving the confluence of the SMV and the SpV. Cisplatin-based neoadjuvant chemotherapy was delivered; main tumor shrank and AFP levels decreased to below one hundredth. However, PVTT remained in the bilateral portal branches to the main trunk of PV. We describe the technical details of the portal venous tumor thrombectomy that was succeeded by a LDLT. The patient remained healthy 2.5 yr after LDLT, showing good patency of the PV with no evidence of recurrence of tumor.

    An IL-2 receptor antagonist, basiliximab, decreases the frequency of ACR in liver transplant (LT) recipients as induction therapy. The aim of this study was to evaluate the effectiveness of basiliximab against SRR as rescue therapy in pediatric LT patients with ALF. Forty pediatric ALF patients underwent LT between November 2005 and July 2013. Among them, seven patients suffering from SRR were enrolled in this study. The median age at LT was 10 months (6-12 months). SRR was defined as the occurrence of refractory rejection after more than two courses of steroid pulse therapy. Basiliximab was administered to all patients. The withdrawal of steroids without deterioration of the liver function was achieved in six patients treated with basiliximab therapy without patient mortality, although one patient developed graft loss and required retransplantation for veno-occlusive disease. The pathological examinations of liver biopsies in the patients suffering from SRR revealed severe centrilobular injuries, particularly fibrosis within one month after LT. We demonstrated the effectiveness and safety of rescue therapy consisting of basiliximab for SRR in pediatric LT recipients with ALF.

    BACKGROUND: The selection of an adequate graft to mitigate the problems associated with a large-for-size graft is essential to ensure the success of liver transplantation for smaller children. Reduced left lateral segment (LLS) grafts have been introduced to overcome this issue. METHODS: Five infants underwent living donor liver transplantation (LDLT) with segment 2 grafts. In the preoperative assessment, the graft-to-recipient weight ratio (GRWR) and the ratio of the thickness of the donor LLS were used as a reference index for graft size matching, and a 3-dimensional (3D) computer-generated model of the donor liver was used for the analysis of the intrahepatic vasculature. During the donor operation, the relevant portal vein branches feeding to the reduced part of segment 3 were first exposed and divided, and then the parenchymal transection was performed. RESULTS: Segment 2 grafts were selected in 3 cases and reduced segment 2 grafts were selected in the other 2 cases. The graft reduction was achieved with 46.6 ± 8.2% of the actual LLS, and thus the GRWR was reduced from 5.33 ± 2.09% to 2.70 ± 0.82%. The actual graft thickness was reduced by approximately half after the graft reduction. Primary abdominal closure was performed in all of the recipients. No surgical complications occurred in any of the donors or recipients. CONCLUSION: A segment 2 graft could be a valuable option for graft type selection in LDLT for smaller children. Precise planning using a 3D computer-generated model of the donor liver and meticulous operative procedures are necessary to obtain a viable graft.

    CACS is rare, although it has been reported to be a potential risk factor for hepatic artery thrombosis following LT. We herein present the case of a 14-yr-old male with stenosis of the origin of the celiac trunk. Preoperative CT and color ultrasonography showed narrowing of the proximal celiac artery. The patient underwent DDLT with standard arterial reconstruction without dividing the gastroduodenal artery. His postoperative course was uneventful, with an excellent hepatic artery flow on Doppler ultrasonography. Applying a meticulous preoperative evaluation and the appropriate surgical technique is crucial in patients with CACS.

    CPM is one of the most serious neurological complications that can occur after OLT and is characterized by symmetrical demyelinization in the basis pontis. The etiology of CPM remains unclear, although the rapid correction of the serum sodium and CNI concentrations may be associated with the development of CPM. With recent advances in MRI technology, early diagnosis of CPM has become possible. Here, we present the case of a five-yr-old female who developed CNI-associated CPM after undergoing LDLT. A decreased level of consciousness and dysphasia was noted one wk after LDLT, and MRI revealed findings compatible with a diagnosis of CPM. The patient fully recovered from the neurological deficits related to CPM following the switch from the CNI to sirolimus. We propose MRI to be promptly considered for patients with abnormal neurological findings, together with the substitution of CNI with an mTOR inhibitor as a management regimen for CNI-related CPM.

    PURPOSE: The aim of this study was to analyze the outcomes of children added to the waiting list for deceased donor liver transplantation (DDLT) and the results of DDLT in a single Japanese center. METHODS: Forty-seven children were listed on the organ allocation system for DDLT. The priority points related to the medical status of each patient were evaluated and stratified into four categories; 10, 8, 6, and 3 points. The clinical data were collected from the medical records, and the outcomes were analyzed. RESULTS: There were 10 priority points in 25 patients, 6 points in 13 and 3 points in 9. Ten recipients (21.3 %); 7 patients with 10 points and 3 patients with 6 points, underwent DDLT. Seven out of the 10 recipients received split/reduced liver grafts. The surgical complications consisted of biliary stricture, hepatic venous outflow obstruction, intraabdominal abscess and intraabdominal bleeding. Two recipients, who were critically-ill before DDLT, died due to sepsis. The one-year graft survival rate was 70.0 %, with a median follow-up period of 6.4 months. CONCLUSION: The initial experience with pediatric DDLT in our series was satisfactory. Split LT of deceased donor organs may have the potential to resolve the serious organ shortage in Japan.

    We report a first pediatric liver transplantation from a brain-dead donor under 6-year-old in Japan. A 9-month-old girl suffered from graft failure after living donor liver transplantation for biliary atresia. The deceased donor liver transplantation (DDLT) from under 6-year-old was performed. It was important to select appropriate surgical devices for the pediatric organ recovery based on the preoperative evaluation. Sufficient vessel grafts were procured because of difficult vascular reconstruction. She discharged on 172 days after DDLT. There have been few cases of pediatric organ donation in Japan. Therefore we should make careful preparation for both of donor and recipient.

    More details Close

    Bile acids are reabsorbed in the lower part of the small intestine, transported to the liver via the portal vein, chemically conjugated, and then secreted back into the small intestine for enterohepatic circulation. Progressive familial intrahepatic cholestasis type 1 (PFIC 1) is a heterozygous mutation of the membrane protein ATP8B1 gene that causes malabsorption by secondarily decreasing the expression of bile acid transporters such as SLC10A2. In this study, we succeeded in producing small intestinal organoids from PFIC1-iPS cells, and characterized them and constructed a model for visualizing bile acid absorption. Quantitative PCR analysis revealed decreased expression of SLC10A2, a bile acid transporter, and decreased bile acid absorption compared with controls.
