Abstract
PURPOSE Biliary complications develop at a higher rate in living donor liver transplantation (LDLT) compared with cadaveric liver transplantation. Almost all studies about biliary complications after LDLT were made with the right lobe. The aim of this study was to determine the frequency of biliary complications developing after adult left lobe LDLT and to evaluate the efficacy of the algorithm followed in diagnosis and treatment, particularly percutaneous radiological treatment. METHODS A total of 2185 LDLT operations performed in our center between May 2009 and December 2019 were retrospectively reviewed and patients receiving left lobe LDLT were analyzed regarding biliary complications and treatments. Biliary complications were treated via percutaneous drainage under ultrasound (US) guidance, endoscopic retrograde cholangiopancreatography (ERCP), and percutaneous transhepatic cholangiography (PTC)/ percutaneous transhepatic biliary drainage (PTBD). Patient demographics, ERCP procedures before percutaneous treatment, and percutaneous treatment indications were analyzed. RESULTS A total of 69 adult patients received left lobe LDLT. Biliary complications requiring endoscopic and/or percutaneous treatment developed in 28 patients (40%). Of these patients, 4 had bile leakage (14%), 20 had anastomosis stricture (72%), and 4 had both leakage and anastomosis stricture (14%). External drainage treatment under ultrasound guidance was sufficient for 2 of 4 patients with bile leakage, and these cases were accepted as minor bile leakage (7%). Overall, 26 patients underwent ERCP; of these, 8 were referred for PTC/PTBD because the guidewire and/or balloon-stent could not pass the anastomosis stricture (n=7) and common bile duct cannulation could not be obtained because of duodenal diverticulum (n=1). Diagnostic PTC was performed in 10 patients, 8 were referred after inadequate/failed ERCP procedure and two were referred directly without ERCP. Anastomosis stricture was found in 7 patients and anastomosis stricture and bile leakage in 3. In 7 patients determined to have stricture, balloon dilatation was applied and then biliary drainage was performed. In 3 patients who had leakage and anastomosis stricture, balloon dilatation was applied for stricture; after dilatation, an IEBD catheter was placed through the leakage region in 2 patients, while a covered metallic stent passing through the leakage region was placed in one patient. CONCLUSION Generally, ERCP is the first preferred method in biliary complications of LDLT; however, in cases where a response cannot be obtained by endoscopic treatment or require complex and/or aggressive treatment, percutaneous radiological treatment should be the treatment of choice before surgery in left lobe LDLT.

Abstract
The field of organ preservation is filled with advancements that have yet to see widespread clinical translation, with some of the more notable strategies deriving their inspiration from nature. While static cold storage (SCS) at 2 °C to 4 °C is the current state-of-the-art, it contributes to the current shortage of transplantable organs due to the limited preservation times it affords combined with the limited ability of marginal grafts (i.e. those at risk for post-transplant dysfunction or primary non-function) to tolerate SCS. The era of storage solution optimization to minimize SCS-induced hypothermic injury has plateaued in its improvements, resulting in a shift towards the use of machine perfusion systems to oxygenate organs at normothermic, sub-normothermic, or hypothermic temperatures, as well as the use of sub-zero storage temperatures to leverage the protection brought forth by a reduction in metabolic demand. Many of the rigors that organs are subjected to at low sub-zero temperatures (-80 °C to -196 °C) commonly used for mammalian cell preservation have yet to be surmounted. Therefore, this article focuses on an intermediate temperature range (0 °C to -20 °C), where much success has been seen in the past two decades. The mechanisms leveraged by organisms capable of withstanding prolonged periods at these temperatures through either avoiding or tolerating the formation of ice has provided a foundation for some of the more promising efforts. This article therefore aims to contextualize the translation of these strategies into the realm of mammalian organ preservation.

Abstract
BACKGROUND Endoscopic biliary stenting (EBS) with a fully covered, self-expandable metallic stent (FC-SEMS) and plastic stent (PS) is safe and efficient for biliary anastomotic strictures (ASs) after a deceased donor liver transplantation. Limited studies have investigated the use of FC-SEMSs for biliary strictures post-living donor liver transplantation (LDLT). We compared the resolution rate of biliary ASs post-LDLT and the 12-month recurrence rates post-stent removal between EBS with an FC-SEMS, PS, and percutaneous transhepatic biliary drainage (PTBD). METHODS Patients with biliary ASs after an LDLT (mean age: 57.3 years, 76.1% men) hospitalized between 2014 and 2017 were enrolled. Endoscopic retrograde cholangiopancreatography (ERCP) was repeated every 3-4 months. Patients were followed-up for at least 1-year post-stent removal. RESULTS Of the 75 patients enrolled, 16, 20, and 39 underwent EBS with an FC-SEMS, PS, and PTBD, respectively. Median follow-up period was 39.2 months. Fewer ERCP procedures were needed in the FC-SEMS group than in the PS group (median, 2 vs. 3; P = 0.20). Median stent indwelling periods were 4.7, 9.3, and 5.4 months in the FC-SEMS, PS, and PTBD groups, respectively (P = 0.006). The functional resolution rate was lower in the PS group (16/20) than in the FC-SEMS (16/16) or PTBD (39/39) group (P = 0.005). The radiologic resolution rate was higher in the FC-SEMS group (16/16) than in the PS group (14/20) (P = 0.07). The 12-month recurrence rates showed no significant differences (FC-SEMS, 4/16; PS, 3/16; PTBD, 6/39; P = 0.66). The rates of complications during treatment differed significantly between the groups (P = 0.04). Stent migration occurred in 1 (6.3%) and 5 (25.0%) patients in the FC-SEMS and PS groups, respectively (P = 0.59). CONCLUSIONS EBS with an FC-SEMS is comparable with EBS with a PS or PTBD in terms of biliary stricture resolution and 12-month recurrence rates. The use of FC-SEMSs is potentially effective and safe for biliary AS resolution after LDLT.

Abstract
NODAT (new-onset diabetes after transplantation) is an important complication after liver transplant, however, there is variation in the reported incidence of NODAT. Therefore, a meta-analysis was performed to estimate the incidence of NODAT in liver transplant. Electronic databases were searched for articles regarding NODAT incidence after liver transplantation. Incidence of NODAT were analyzed at six different timepoints. Summary statistics were calculated using a generalized linear mixed model in random effects. 28 articles were included and out of a pooled population of 71,257 patients, overall incidence of NODAT was found to be 15.51%, 16.09%, 18.30%, 20.86%, 18.08%, 25.05% for three-months, six-months, one-year, three-year, five-year, and ten-year timepoints respectively. After a sensitivity analysis which only included articles with clear definitions of NODAT, the incidence of NODAT was found to be higher at three-year (21.79%), five-year (25.82%), and ten-year (44.95%) timepoints. Subgroup analysis according to ethnicity found no significant differences for all timepoints. However, studies with predominantly Asian participants generally had a higher incidence of NODAT. In conclusion, this meta-analysis provides a pooled estimate of the incidence of NODAT following liver transplantation. Further studies are required to provide a more comprehensive understanding on how ethnicity can affect the incidence of NODAT.

Liver Transplantation Following Yttrium-90 Radioembolization: 15-Year Experience in 207-Patient Cohort. Hepatology 2021; 73:998-1010.

Abstract
BACKGROUND AND AIMS Radioembolization (yttrium-90 [Y90]) is used in hepatocellular carcinoma (HCC) as a bridging as well as downstaging liver-directed therapy to curative liver transplantation (LT). In this study, we report long-term outcomes of LT for patients with HCC who were bridged/downstaged by Y90. APPROACH AND RESULTS Patients undergoing LT following Y90 between 2004 and 2018 were included, with staging by United Network for Organ Sharing (UNOS) tumor-node-metastasis criteria at baseline pre-Y90 and pre-LT. Post-Y90 toxicities were recorded. Histopathological data of HCC at explant were recorded. Long-term outcomes, including overall survival (OS), recurrence-free survival (RFS), disease-specific mortality (DSM), and time-to-recurrence, were reported. Time-to-endpoint analyses were estimated using Kaplan-Meier. Univariate and multivariate analyses were performed using a log-rank test and Cox proportional-hazards model, respectively. During the 15-year period, 207 patients underwent LT after Y90. OS from LT was 12.5 years, with a median time to LT of 7.5 months [interquartile range, 4.4-10.3]. A total of 169 patients were bridged, whereas 38 were downstaged to LT. Respectively, 94 (45%), 60 (29%), and 53 (26%) patients showed complete, extensive, and partial tumor necrosis on histopathology. Three-year, 5-year, and 10-year OS rates were 84%, 77%, and 60%, respectively. Twenty-four patients developed recurrence, with a median RFS of 120 (95% confidence interval, 69-150) months. DSM at 3, 5, and 10 years was 6%, 11%, and 16%, respectively. There were no differences in OS/RFS for patients who were bridged or downstaged. RFS was higher in patients with complete/extensive versus partial tumor necrosis (P < 0.0001). For patients with UNOS T2 treated during the study period, 5.2% dropped out because of disease progression. CONCLUSIONS Y90 is an effective treatment for HCC in the setting of bridging/downstaging to LT. Patients who achieved extensive or complete necrosis had better RFS, supporting the practice of neoadjuvant treatment before LT.

Abstract
Tacrolimus was discovered in 1984 and entered clinical use shortly thereafter, contributing to successful solid organ transplantation across the globe. In this review, we cover development of tacrolimus, its evolving clinical utility, and issues affecting its current usage. Since earliest use of this class of immunosuppressant, concerns for calcineurin-inhibitor toxicity have led to efforts to minimize or eliminate these agents in clinical regimens but with limited success. Current understanding of the role of tacrolimus focuses more on its efficacy in preventing graft rejection and graft loss. As we enter the fourth decade of tacrolimus use, newer studies utilizing novel combinations (as with the mammalian target of rapamycin inhibitor, everolimus, and T-cell costimulation blockade with belatacept) offer potential for enhanced benefits.

Abstract
Background Liver transplantation (LT) is a life-saving treatment for patients with end-stage liver disease and acute liver failure. However, in-hospital death cannot be avoided. We designed this study to analyze patients' in-hospital mortality rate after LT and the factors correlated with in-hospital death. Methods The data of patients who received LT in our hospital between January 11, 2015, and November 19, 2019, were obtained from the China Liver Transplant Registry and medical records. The in-hospital mortality rate was calculated, and factors related to mortality, cause of death, and factors related to cause of death were analyzed by reviewing patients' data. Results A total of 529 patients who underwent cadaveric LT were enrolled in this study. Modified piggyback orthotopic LT was performed for all patients. Seventy patients died in the hospital after LT, and the in-hospital mortality rate was 13.2%. Factors including model for end-stage liver disease (MELD) score, Child-Pugh grading, intraoperative blood loss, and anhepatic phase were correlated with in-hospital death. MELD score and intraoperative blood loss were determined as the two independent risk factors of in-hospital death. The first two causes of death were infection (34.3%) and primary non-function (15.7%). Pulmonary fungal infection was the main cause of infectious death. MELD score was the independent risk factor for infectious death, and both body mass index of donors and cold ischemic time were independent risk factors of primary non-function. Conclusions In-hospital death poses a threat to certain patients undergoing LT. Our study suggests that the main cause of in-hospital death is an infection, followed by primary non-function.

Abstract
BACKGROUND The liver transplant risk score (LTRS) was developed to stratify 90-day mortality of patients referred for liver transplantation (LT). We aimed to validate the LTRS using a new cohort of patients. METHODS The LTRS stratifies the risk of 90-day mortality of LT recipients based on their age, body mass index, diabetes, model for end-stage liver disease (MELD) score, and need for dialysis. We assessed the performance of the LTRS using a new cohort of patients transplanted in the United States between July 2013 and June 2017. Exclusion criteria were age <18 years, ABO incompatibility, redo or multivisceral transplants, partial grafts, malignancies other than hepatocellular carcinoma and fulminant hepatitis. RESULTS We found a linear correlation between the number of points of the LTRS and 90-day mortality. Among 18 635 recipients, 90-day mortality was 2.7%, 3.8%, 5.2%, 4.8%, 6.7%, and 9.3% for recipients with 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). The LTRS also stratified 1-year mortality that was 5.5%, 7.7%, 9.9%, 9.3%, 10.8%, and 15.4% for 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). An inverse correlation was found between the LTRS and 4-year survival that was 82%, 79%, 78%, 82%, 78%, and 66% for patients with 0, 1, 2, 3, 4, and ≥5 points (P < 0.001). The LTRS remained an independent predictor after accounting for recipient sex, ethnicity, cause of liver disease, donor age, cold ischemia time, and waiting time. CONCLUSIONS The LTRS can stratify the short- and long-term outcomes of LT recipients at the time of their evaluations irrespective of their gender, ethnicity, and primary cause of liver disease.

Abstract
Extended survival of liver transplant recipients has brought rejection management to the forefront of liver transplant research. This article discusses T-cell-mediated rejection, antibody-mediated rejection, and chronic rejection. We focus on the prevention and then discuss treatment options. Future directions of rejection management include biomarkers of rejection, which may allow for monitoring of patients who are considered high risk for rejection and detection of rejection before there is any clinical evidence to improve graft and patient survival. With improved graft life and survival of liver transplant recipients, the new frontier of rejection management focuses on immunosuppression minimization, withdrawal, and personalization.

Abstract
AIM This this study aimed to investigate the causes and prognoses of liver re-transplantation in patients referred to Imam Khomeini Hospital Liver Transplantation Center. BACKGROUND Organ shortage is a major problem in the world, a high demand for liver transplantation has exacerbated this problem. Thus, providing more information on the causes of liver re-transplantation, its prognosis, and other issues related to this procedure is of great importance. METHODS This study was conducted in 2018 as a historical cohort. In this study, the records of liver transplantation patients at Imam Khomeini Hospital Liver Transplantation Center between 2000 and 2016 were studied, and data was extracted from the records of patients undergoing liver transplantation. Patient data was entered into SPSS 20 software and analyzed. RESULTS In this study, 1030 patients with a mean age of 43.15 ± 14.57 years were studied. There were 426 women (41.4%) and 604 men (58.6%). The number of primary transplants was 966 with a mean age of 43.19 ± 14.72, and the number of re-transplants was 64 with a mean age of 42.56 ± 12.82. Significant differences were found between the two groups in terms of MELD and CHILD scores, cold ischemic time, total and direct bilirubin levels, liver function factors (ALT, AST, and alkaline phosphatase), hemoglobin, and WBC. There was no significant difference between the two groups in terms of age, sex, or platelets (> 0.05). The mortality rate was 241 (23.39%) in all patients and the mortality rate was 206 (21.32%) and in liver transplant patients was 35 (54.68%). The mortality rate in the transplant group was statistically higher (p<0.001). Secondary was primary non-functional graft (PNF) (37.5%) with 1-, 3, and 5-year survival rates of 82%, 81%, and 70% in primary group and 59%, 43% and 32% in re-transplantation, respectively. There was a significant difference in survival between the two groups (p <0.05). Hemoglobin and alkaline phosphatase were predictors of survival rates in transplant patients. CONCLUSION The results of this study showed that the survival rate of re-transplant patients was significantly lower than that of primary transplant patients, and the mortality rate in re-transplant patients was significantly higher.

Abstract
BACKGROUND Liver transplantation is the most suitable treatment option available for end-stage liver disease. However, some patients require retransplantation, despite medical advances that have led to improved survival. We aimed to compile a definitive, nationwide resource of liver retransplantation data in Japan, seeking to identify the predictors of patient survival posttransplantation. METHODS Questionnaires were sent to 32 institutions that had conducted 281 retransplantations before 2015. RESULTS Among the 265 patients included in this study (142 pediatric cases), the average age at primary transplantation was 23 years, and retransplantation was performed after an average of 1468 days. The main indication for retransplantation was graft rejection (95 patients). Living-donor liver transplantation accounted for 94.7% of primary transplantations and 73.2% of retransplantations. Patient survival at 1, 3, or 5 years did not differ by type of transplantation but was better for pediatric (70.8%, 68.3%, and 60.1%, respectively) than for adult (57.2%, 50.4%, and 45.2%, respectively) recipients (P = 0.0003). Small-for-size syndrome, retransplantation within 365 days, and inpatient status at retransplantation were significant predictors of poor survival in pediatric cases. Retransplantation within 365 days and conditions warranting retransplantation were significant predictors of poor survival in adult patients. CONCLUSIONS In Japan, where >70% of retransplantations are performed using living donors, the indications and timing are different from those in previous reports from other countries, while maintaining comparable survival rates. Considering technical challenges, graft failure within 365 days should be thoroughly restricted to justify the use of living donor.

Abstract
OBJECTIVE To evaluate factors related to liver graft survival with a focus on immunosuppressive schemes based on calcineurin inhibitors (tacrolimus or cyclosporine). METHODOLOGY This study was carried out through an open cohort constructed by deterministic and probabilistic matching through three databases of the SUS with assessment of liver graft survival from 2000 to 2015 in Brazil. From this first cohort, a second cohort was constructed by pairing 1: 1 to more precisely assess the effect of the immunosuppressive scheme on graft survival. The Kaplan-Meier method and was used to estimate the probability of survival. Cox's model of proportional risks was used to assess factors related to graft loss. RESULT We found 12,687 patients in the Full cohort and 470 patients in the Matched cohort. The overall graft survival rates at 1, 5, 10, and 16 years were 72.6, 63.3, 52.8, and 45.3%, respectively. Patients younger had a longer graft survival than older ones. In the Full cohort, male patients had a higher survival rate than female ones. Therapeutic schemes based on tacrolimus were more prevalent and had a better survival rate when compared to schemes that used cyclosporine. Tacrolimus without association with antiproliferative agents or rapamycin inhibitors was the therapeutic scheme associated with greater survival rate in both cohorts (HR = 0.81, 95% CI = 0.72-0.91), (HR = 0.50, 95% CI = 0.30-0.85). In addition, white-skinned patients had longer survival rate in both cohorts (HR = 0.55, 95% CI = 0.50-0.61 and HR = 0.50, 95% CI = 0.34-0.75). On the other hand, patients who a greater time ratio without using an immunosuppressant had lower graft survival rate (HR = 6.46, 95% CI = 5.05-8.27 and HR = 6.57, 95% CI = 2.66-16.22). CONCLUSION This 16-year cohort showed that the older age and the greater time ratio without using an immunosuppressant are risk factors for liver graft loss. White-skinned patients and tacrolimus-based regimens, especially tacrolimus without other immunosuppressants, are factors of better prognosis to the graft.

Abstract
PURPOSE To evaluate the effective doses received by donors and recipients, identify effective dose contributions, and make risk assessments. MATERIALS AND METHODS It was a retrospective study. 100 Donors and 100 recipients were enrolled with an operative day from March 2016 to August 2017. The dose was analyzed for all radiation-related examinations over a period of 2 years, 1 year before and 1 year after the LDLT procedure. The effective doses of plain X-rays, CT, fluoroscopy, and nuclear medicine per patient were simulated by a Monte Carlo software, evaluated by the dose-length product conversion factors, evaluated by the dose-area product conversion factors, and evaluated by the activity conversion factors, respectively. The risks of radiation-induced cancer were assessed on the basis of the ICRP risk model. RESULTS The median effective doses were 71 (range: 30-186) mSv for donors and 147 (32-423) mSv for recipients. The radiation examinations were mainly performed in the last three months of preoperative period to first month of postoperative period for recipients and donors. The HCC recipients received a higher effective dose, 195 (64-423) mSv, than those with other indications. The median radiation-induced cancer risk was 0.38 % in male and 0.48 % in female donors and was 0.50 % in male and 0.58 % in female recipients. CONCLUSION Donors and recipients received a large effective dose, mainly from the CT scans. To reduce effective doses should be included in future challenges in some living donor liver transplants centers that often use CT examinations.

Infrarenal versus supraceliac aorto-hepatic arterial revascularisation in adult liver transplantation: multicentre retrospective study. Updates Surg 2020; 72:659-669. [PMID: 32594369 DOI: 10.1007/s13304-020-00839-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Accepted: 06/21/2020] [Indexed: 10/24/2022]
Abstract
When the standard arterial reconstruction is not feasible during liver transplantation (LT), aorto-hepatic arterial reconstruction (AHAR) can be the only solution to save the graft. AHAR can be performed on the infrarenal (IR) or supraceliac (SC) tract of the aorta, but the possible effect on outcome of selecting SC versus IR reconstruction is still unclear. One hundred and twenty consecutive patients who underwent liver transplantation with AHAR in six European centres between January 2003 and December 2018 were retrospectively analysed to ascertain whether the incidence of hepatic artery thrombosis (HAT) was influenced by the type of AHAR (IR-AHAR vs. SC-AHAR). In 56/120 (46.6%) cases, an IR anastomosis was performed, always using an interposition arterial conduit. In the other 64/120 (53.4%) cases, an SC anastomosis was performed; an arterial conduit was used in 45/64 (70.3%) cases. Incidence of early (≤ 30 days) HAT was in 6.2% (4/64) in the SC-AHAR and 10.7% (6/56) IR-AHAR group (p = 0.512) whilst incidence of late HAT was significantly lower in the SC-AHAR group (4.7% (3/64) vs 19.6% (11/56) - p = 0.024). IR-AHAR was the only independent risk factor for HAT (exp[B] = 3.915; 95% CI 1.400-10.951; p = 0.009). When AHAR is necessary at liver transplantation, the use of the supraceliac aorta significantly reduces the incidence of hepatic artery thrombosis and should therefore be recommended whenever possible.

Protective Role of the Portocaval Shunt in Liver Transplantation. Transplant Proc 2020; 52:1455-1458.

Abstract
BACKGROUND Advances in medical management and surgical technique have resulted in stepwise improvements in early post-transplant survival rates. Modifications in the surgical technique, such as the realization of the portocaval shunt (PCS), could influence survival rates. The aim of this study was to evaluate the mortality rate for 12 months after liver transplantation, analyzing the causes and risk factors related to its development and assessing the impact that PCS could have on them. METHODS A total of 231 recipients were included in the retrospective, longitudinal, and nonrandomized study. RESULTS The overall survival of the transplant was 85.2% (197 patients). The most frequent cause of death was infection (38.2%), followed by the multiorgan failure of multiple etiology (23.5%). Most of the risk factors related to mortality correspond to variables of the postoperative period. The results of the multivariate analysis identified the main risk factors for death: the presence of surgical complications and the need for renal replacement therapy. In contrast, the performance of PCS exerted a protective effect, reducing the probability of death by 70%. CONCLUSIONS Despite the good results obtained in several studies, there is still debate regarding the benefit of its realization. In our study, PCS was a factor associated with a reduction in mortality, with a markedly lower probability of adverse events. However, we agree with other authors on the need for larger and randomized studies to adequately determine the validity of such results.

Abstract
BACKGROUND Liver retransplantation can be classified as urgent (when performed in the first week after the transplantation) or elective, which may be considered as early (first month post-transplantation) or late (after the first month). The time in which retransplantation takes place is determined by the cause that makes it necessary. The goal of this study is to analyze the causes and results of early retransplantation in our center. METHODS A retrospective analysis of liver retransplantations performed within the first month after the original transplantation in our center between 2007 and 2017 was carried out. The variables analyzed were demographic, causes of the first transplant and retransplantation, and the complications and mortality resulting from the latter. RESULTS A total of 698 liver transplants were performed, including 67 patients who required retransplantation (8.9%). Among these, 37 were late elective retransplantations and 30 were early retransplantations. Regarding the latter, the causes that led to the first transplant were hepatocellular carcinoma (46.7%) and noncholestatic cirrhosis (30%). On the other hand, the main precipitants of the retransplantation were hepatic artery thrombosis (60%) and primary graft failure (13.3%). The reoperation rate was 16.7%, and the perioperative mortality rate was 16.7%. The 1-, 2-, and 5-year survival rates were 83.3%, 76.7% and 59.9%, respectively. CONCLUSION Despite the high perioperative morbidity of liver retransplantation, its results in terms of survival are similar to those of the global series of liver transplantation.

Abstract
BACKGROUND The albumin-bilirubin (ALBI) grade, stratified from the ALBI score, may have prognostic value in patients with hepatocellular carcinoma. We aim to evaluate the prognostic abilities of the ALBI score/grade among living-donor liver transplantation patients. METHODS We retrospectively collected data of 81 patients who underwent living-donor liver transplant at Kobe University Hospital between June 2000 and October 2018. The efficacy of the ALBI score/grade as a prognostic factor was assessed and compared with that of the well-established Model for End-Stage Liver Disease (MELD) score. MAIN FINDINGS Multivariate analysis indicated that recipient age (P = .003), donor age (P = .003), ALBI score ≥ -1.28 (P = .002), and ALBI grade III (P = .004) were independently associated with post-transplant survival. A high MELD score was not associated with post-transplant survival in univariate or multivariate analyses. Although there was no significant difference in the overall survival rate relative to recipient and donor age, ALBI score/grade was significantly associated with the 1- and 5-year survival rates (P = .023, P = .005). ALBI scores specifically detected fatal complications of post-transplant graft dysfunction (P = .031) and infection (P = .020). CONCLUSION ALBI score/grade predicted patient survival more precisely than the MELD score did, suggesting that it is a more useful prognostic factor compared to the MELD score in living-donor liver transplantation cases.

Abstract
BACKGROUND Observed long-term outcomes no longer reflect the survival trajectory facing pediatric liver transplant (LT) recipients today. We aimed to use national registry data and parametric models to project 20- and 30-year post-transplant outcomes for recently transplanted pediatric LT recipients. METHODS We conducted a retrospective cohort study of 13,442 first-time pediatric (age <18) LT recipients using 1987 to 2018 Scientific Registry of Transplant Recipients data. We validated the proposed method (ie, to project long-term patient and graft survival using parametric survival models and short-term data) in 2 historic cohorts (1987-1996 and 1997-2006) and estimated long-term projections among patients transplanted between 2007 and 2018. Projections were stratified by raft type, recipient age, and indication for transplant. RESULTS Parsimonious parametric models with Weibull distribution can be applied to post-transplant data and used to project long-term outcomes for pediatric LT recipients beyond observed data. Projected 20-year patient survival for pediatric LT recipients transplanted in 2007 to 2018 was 84.0% (95% confidence interval 81.5-85.8), compared to observed 20-year survival of 72.8% and 63.6% among those transplanted in 1997 to 2006 and 1987 to 1996, respectively. Projected 30-year survival for pediatric LT recipients in 2007 to 2018 was 80.1% (75.2-82.7), compared to projected 30-year survival of 68.6% (66.1-70.9) in the 1997 to 2006 cohort and observed 30-year survival of 57.5% in the 1987 to 1996 cohort. Twenty- and 30-year patient and graft survival varied slightly by recipient age, graft type, and indication for transplant. CONCLUSIONS Projected long-term outcomes for recently transplanted pediatric LT recipients are excellent, reflective of substantial improvements in medical care, and informative for physician-patient education and decision making in the current era.

Abstract
BACKGROUND AND AIMS Liver transplantation has become an effective therapy for patients with end-stage liver disease. The risk of new-onset diabetes after transplantation (NODAT) and posttransplant metabolic syndrome (PTMS) is high among patients after liver transplantation. These are thought to be associated with increased risks of graft rejection, infection, cardiovascular disease, and death. Our study aimed to document the incidence of NODAT and PTMS and analyze pre and posttransplant predictive factors for their development in patients undergoing a liver transplant. METHODS This was a prospective comparative study on 51 patients who underwent live donor liver transplantation. They were evaluated at baseline, 3 and 6 months after transplantation with fasting glucose, lipids, serum insulin levels, C-peptide, and HbA1C. They were followed up at 5 years to document any cardiovascular events or rejection. RESULTS The incidence of preoperative diabetes mellitus (DM) in the study group was 25/51 (49%). The incidence of NODAT was 38.5% (10/26 patients) and PTMS 29% (10/35), respectively. Age (47.7 ± 5.4 vs 41.5 ± 12.7 years), HOMA2 - IR (2.3 ± 1.8 vs 2.1 ± 1.6), serum insulin (16.1 ± 12.0 vs 17.9 ± 14.5), and C-peptide (4.6 ± 0.5 vs 4.8 ± 0.7) were similar at baseline in the NODAT group compared to those who did not develop it. Mean tacrolimus levels were higher in PTMS group (6.8 ± 2.9 vs 5.0. ± 2.0 P value = 0.042). By the end of 5 years, 7 patients expired; 6 due to rejection and one due to cardiovascular disease. Moreover, 2 of these patients had preexisting DM and 2 had NODAT. CONCLUSIONS None of the baseline metabolic factors in patients undergoing liver transplant were predictive of the development of NODAT or PTMS. Mean tacrolimus levels were significantly higher in the PTMS group. A 5-year follow-up showed no excess risk of cardiovascular events or rejection in those with preexisting DM or in those who developed NODAT.

Abstract
End-stage liver disease is characterized by multiple and complex alterations of hemostasis that are associated with an increased risk of both bleeding and thrombosis. Liver transplantation further challenges the feeble hemostatic balance of patients with decompensated cirrhosis, and the management of antithrombotic treatment during and after transplant surgery, which is particularly difficult. Bleeding was traditionally considered the major concern during and early after surgery, but it is increasingly recognized that transplant recipients may also develop thrombotic complications. Pathophysiology of hemostatic complications during and after transplantation is multifactorial and includes pre-, intra-, and postoperative risk factors. Risk stratification is important, as it helps the identification of high-risk recipients in whom antithrombotic prophylaxis should be considered. In recipients who develop thrombosis during or after surgery, prompt treatment is indicated to prevent graft failure, retransplantation, and death.

Abstract
BACKGROUND Liver retransplantation (re-LT) accounts for up to 22% after primary liver transplantation (LT), and using donor livers for retransplantation can only be justified by successful outcomes. METHODS A total of 2,387 adult recipients with 2,778 LT, between 1979 and 2017, were analyzed to determine risk factors and outcome of re-LT in the Netherlands. RESULTS Of 2,778 LT, 336 (12.1%) were first, 43 (1.5%) were second, and 12 (0.5%) were third or fourth re-LT. The 5-year patient survival for primary LT, and first, second, and third or fourth re-LT were 74.0%, 70.8%, 63.3%, and 57.1%, respectively (P = 0.10). Recipient age (≤60 years) (OR 1.96, P < 0.001), era (1979-2006) (OR 1.56, P = 0.003), donor after circulatory death (DCD) (OR 1.96, P < 0.001), and cold ischemia time (CIT) (>9 h) (OR 1.42, P = 0.007) were significant risk factors for retransplantation after primary LT. CONCLUSIONS Recipient age, era, DCD, and prolonged CIT were identified as parameters for retransplantation. The outcome after the first re-LT was good, and comparable to those of primary transplants. Survival after multiple re-LT was not significantly different from the first retransplant group, legitimizing third and fourth re-LT to well-selected patients.

Abstract
Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections worldwide and is associated with precancerous lesions and cancers of the cervix, vulva, vagina, penis, anus, tonsils and base of the tongue. Several studies show an increased risk of HPV-associated cancers in solid organ transplant recipients (SOTR). The aims of this review are to investigate the evidence of efficacy for the HPV vaccination in transplant recipients and to discuss the known national guidelines. A systematic literature search has been conducted to identify studies where SOTR received the HPV vaccination to evaluate the efficacy of the HPV vaccine on this population. The primary outcome was antibody response against the HPV genotypes included in the vaccines and the secondary outcome was national guidelines recommending HPV vaccination of SOTR. Three cohort studies evaluated immunogenicity. Two studies found suboptimal effect of the HPV vaccine, while an early terminated study detected 100% seropositivity. We have identified four national guidelines in the following countries; United States of America, Canada, Australia and Ireland, along with a recommendation from the World Health Organization (WHO). The results from the three studies were inconclusive due to the small sample sizes and the diverging results. Recommendations of HPV vaccination of SOTR is based on the knowledge about safety and efficiency in the general population and the safety of other inactivated (not live) vaccines in SOTR. Theoretically, the nonavalent vaccine should be recommended as the first choice in SOTR without age- or sex restrictions.

Abstract
Introduction Over 19% of deceased organ donors are labeled increased risk for disease transmission (IRD) for viral blood‐borne disease transmission. Many potential organ recipients need to decide between accepting an IRD organ offer and waiting for a non–IRD organ. Methods Using machine learning and simulation, we built transplant and waitlist survival models and compared the survival for patients accepting IRD organ offers or waiting for non–IRD organs for the heart, liver, and lung. The simulation consisted of generating 20 000 different scenarios of a recipient either receiving an IRD organ or waiting and receiving a non–IRD organ. Results In the simulations, the 5‐year survival probabilities of heart, liver, and lung recipients who accepted IRD organ offers increased on average by 10.2%, 12.7%, and 7.2%, respectively, compared with receiving a non–IRD organ after average wait times (190, 228, and 223 days, respectively). When the estimated waitlist time was at least 5 days for the liver, and 1 day for the heart and lung, 50% or more of the simulations resulted in a higher chance of 5‐year survival when the patient received an IRD organ versus when the patient remained on the waitlist. We also developed a simple equation to estimate the benefits, in terms of 5‐year survival probabilities, of receiving an IRD organ versus waiting for a non–IRD organ, for a particular set of recipient/donor characteristics. Conclusion For all three organs, the majority of patients are predicted to have higher 5‐year survival accepting an IRD organ offer compared with waiting for a non–IRD organ.

Abstract
BACKGROUND AND AIMS The anastomotic biliary stricture is a clinically important complication after living donor liver transplantation (LDLT) with a duct-to-duct anastomosis. Although endoscopic management of post-LDLT biliary strictures using balloon dilation (BD) and plastic stents (PSs) has provided acceptable short-term outcomes, long-term outcomes and prognostic factors for treatment success remain unclear. METHODS We included 96 patients with post-LDLT biliary strictures who were endoscopically managed between 2003 and 2016. BD was utilized as a first-line treatment strategy, and PS placement was carried out for refractory cases. Potential prognostic factors for biliary stricture resolution were analysed using logistic regression analyses. RESULTS Endoscopic treatment was technically successful in 84 patients (87.5%). The overall rate of biliary stricture resolution was 44.8% (43 of 96 patients) with a median follow-up duration of 90.9 months (interquartile range, 30.9-122.3 months). Bile duct kinking was associated with a lower rate of biliary stricture resolution (odds ratio, 0.33; 95% confidence interval, 0.13-0.87). After successful endoscopic treatment, biliary strictures recurred in 22 patients (57.9%) after BD, and in one patient (4%) after PS treatment. CONCLUSIONS Despite a high technical success rate, endoscopic treatment only provided a low rate of resolution of anastomotic biliary strictures among LDLT patients and required prolonged treatment duration. Alternative strategies including the use of a covered metal stent should be evaluated to further improve the treatment outcomes of post-LDLT biliary strictures, particularly in those accompanied by the bile duct kinking.

Abstract
The need for liver transplantation (LT) among older patients is increasing, but the role of LT in the elderly (≥70 years) is not well defined. We retrospectively reviewed all primary LTs from 1998 through 2016 at our center. Survival and associated risk factors were analyzed with Cox regression and Kaplan-Meier methods for LT recipients in 3 age groups: <60, 60-69, and ≥70 years. Among 2281 LT recipients, the median age was 56 years (range, 15-80 years), and 162 were aged ≥70 years. The estimated 5- and 10-year patient survival probabilities for elderly LT recipients were lower (70.8% and 43.6%) than for recipients aged 60-69 years (77.2% and 64.6%) and <60 years (80.7% and 67.6%). Patient and graft survival rates associated with LT improved over time from the pre-Model for End-Stage Liver Disease era to Share 15, pre-Share 35, and Share 35 for the cohort overall (P < 0.001), but rates remained relatively stable in septuagenarians throughout the study periods (all P > 0.45). There was no incremental negative effect of age at LT among elderly patients aged 70-75 years (log-rank P = 0.32). Among elderly LT recipients, greater requirement for packed red blood cells and longer warm ischemia times were significantly associated with decreased survival (P < 0.05). Survival of LT recipients, regardless of age, markedly surpassed that of patients who were denied LT, but it was persistently 20%-30% lower than the expected survival of the general US population (P < 0.001). With the aging of the population, select older patients with end-stage liver diseases can benefit from LT, which largely restores their expected life spans.

Abstract
BACKGROUND Hepatocelluar cancer (HCC) is the leading cause of death among people with hepatitis C virus (HCV)-related cirrhosis. Our aim was to determine the optimal surveillance frequency for patients with HCV-related compensated cirrhosis. METHODS We developed a decision analytic Markov model and validated it against data from the Veterans Outcomes and Costs Associated with Liver Disease (VOCAL) study group and published epidemiologic studies. Four strategies of different surveillance intervals were compared: no surveillance and ultrasound surveillance every 12, 6, and 3 months. We estimated lifetime survival, life expectancy, quality adjusted life years (QALY), total costs associated with each strategy, and incremental cost effectiveness ratios. We applied a willingness to pay threshold of $100,000. Analysis was conducted for two scenarios: a scenario reflecting current HCV and HCC surveillance compliance rates and treatment use and an aspirational scenario. RESULTS In the current scenario the preferred strategy was 3-month surveillance with an incremental cost-effectiveness ratio (ICER) of $7,159/QALY. In the aspirational scenario, 6-month surveillance was preferred with an ICER of $82,807/QALY because treating more people with HCV led to a lower incidence of HCC. Sensitivity analyses suggested that surveillance every 12 months would suffice in the particular circumstance when patients are very likely to return regularly for testing and when appropriate HCV and HCC treatment is readily available. Compared with the current scenario, the aspirational scenario resulted in a 1.87 year gain in life expectancy for the cohort because of large reductions in decompensated cirrhosis and HCC incidence. CONCLUSIONS HCC surveillance has good value for money for patients with HCV-related compensated cirrhosis. Investments to improve adherence to surveillance should be made when rates are suboptimal. Surveillance every 12 months will suffice when patients are very likely to return regularly for testing and when appropriate HCV and HCC treatment is readily available.

Abstract
OBJECTIVE To investigate the influence of donor age on recipient outcome after living-donor partial liver transplantation (LDLT). BACKGROUND Donor age is a well-known prognostic factor in deceased donor liver transplantation; however, its role in LDLT remains unclear. METHODS We retrospectively analyzed 315 consecutive cases of primary adult-to-adult LDLT in our center between April 2006 and March 2014. Recipients were divided into 5 groups according to the donor age: D-20s (n = 60); D-30s (n = 72); D-40s (n = 57); D-50s (n = 94); and D-60s (n = 32). The recipient survival and the association with various clinical factors were investigated. RESULTS Recipient survival proportions were significantly higher in D-20s compared with all the other groups (P = 0.008, < 0.001, < 0.001, and = 0.006, vs D-30s, -40s, -50s, and -60s, respectively), whereas there was no association between recipient survival and their own age. There are 3 typical relationships between donors and recipients in adult-to-adult LDLT: from child-to-parent, between spouses/siblings, and from parent-to-child. The overall survival in child-to-parent was significantly higher than in spouses/siblings (P = 0.002) and in parent-to-child (P = 0.005), despite significantly higher recipient age in child-to-parent [59 (42-69) years, P < 0.001]. Contrastingly, parent-to-child exhibited the lowest survival, despite the youngest recipient age [26 (20-43) years, P < 0.001]. In addition, younger donor age exhibited significantly better recipient survival both in hepatitis C virus-related and in non-hepatitis C virus diseases. Univariate and multivariate analyses both demonstrated that donor age and graft-type (right-sided livers) are independent prognostic factors for recipient survival. CONCLUSIONS Donor age is an independent, strong prognostic factor in adult-to-adult LDLT.

Abstract
Background Incisional hernia repair is the most common procedure after orthotopic liver transplantation. Although enhanced recovery protocols are increasingly employed, the post–orthotopic liver transplantation patient may not benefit from all aspects of these models. The aim of the present study is to assess which perioperative interventions and patient factors affect hospital length of stay in a cohort of post–orthotopic liver transplantation patients undergoing incisional hernia repair. Methods We conducted a retrospective review of a series of adult patients undergoing incisional hernia repair after orthotopic liver transplantation. The primary endpoint was length of stay. Results were stratified by demographic, intraoperative, and postoperative variables. Results Eleven percent (172/1523) of patients who received orthotopic liver transplantation during the study period underwent subsequent incisional hernia repair. Median length of stay was 5 days (range 2–50). The strongest predictor of length of stay was postoperative renal function. Despite liberal intraoperative administration of volume (median 642 mL/h) and brisk intraoperative urine output (median 72 mL/h), postoperative acute kidney injury occurred in 48% of patients. Those that developed acute kidney injury received less intraoperative volume (6 vs 8.5 mL/kg/h; P = .031) and the severity of postoperative renal injury was inversely related to the amount intraoperative volume given. Conclusions In patients undergoing incisional hernia repair after orthotopic liver transplantation, postoperative renal function is frequently impaired. Although many aspects of current ERAS protocols may be applied to post-transplant patients, restrictive intraoperative fluid administration strategies should be employed with caution given a high propensity for the development of post-operative acute kidney injury in this complex population. Eleven percent (172/1523) of patients who received OLT during the years 2005 to 2016 underwent subsequent IHR. The strongest predictor of length of stay in this population was postoperative renal function. Despite liberal intraoperative administration of volume (median 642 mL/h; 7 mL/kg/h) and brisk intraoperative urine output (median 72 mL/h), postoperative acute kidney injury (AKI) occurred in 48% of patients. Those that developed AKI received less intraoperative volume (6 vs 8.5 mL/kg/h; P = .031) and the severity of postoperative renal injury was inversely related to intraoperative volume

Abstract
OBJECTIVES Although transplant teams understand the effects of donor characteristics on liver transplant outcomes, few studies have investigated the quality of livers obtained from poisoned donors. The aim of this study was to compare livers procured from poisoned donors with a matched control group. MATERIALS AND METHODS Liver transplant outcomes from poisoned donors and from donors with trauma-induced death (as the control group) were compared using data of an Organ Procurement Unit from 2000 to 2013. Procured livers were evaluated via histology findings before transplant. Recipient characteristics were assessed in both groups, and immediate and medium-term (up to 5 years after transplant) survival rates were compared with the use of Kaplan-Meier analyses and log-rank tests. RESULTS Over a 13-year organ donation program, 1485 livers from brain dead patients were donated. Among them, 115 poisoned donors were evaluated for liver grafts; of these, 74 successful liver transplants were performed. In the poisoned donors, the incidence of reversed cardiac arrest was 54.1%. Likewise, acute kidney injury was detected in 14.9% of the patients, and 16.2% needed urgent dialysis either for clearance of the toxic agents or for treatment of acute kidney injury. No significant differences were observed in 1- to 5-year survival rates, and log-rank test also showed a significance level of 0.83. CONCLUSIONS Proper case selection strategies can be implemented to expand the donor pool, including use of poisoned donors. Hence, poisoning is not a contra-indication for a referral, which could lead to decreased mortality for patients requiring a liver transplant.

Abstract
BACKGROUND & AIMS Both liver disease (LD) and pancreatitis pose substantial burdens. There have been no general population-based studies on frequency of LD after an episode of pancreatitis. The aim of this study was to investigate the occurrence of LD in a population-based cohort of patients following pancreatitis. METHODS Nationwide data on the general population of nearly 3 million people were used to identify retrospectively diagnoses of acute pancreatitis, chronic pancreatitis (CP), LD and cirrhosis from 1998 to 2016. Acute pancreatitis was categorised as first (FAP) or recurrent (RAP) episode. Number of pancreatitis recurrences prior to LD diagnosis was determined. RESULTS A total of 20,931 pancreatitis patients were included, of which 874 developed LD following pancreatitis. The incidence of LD in FAP was 115.59 (95% confidence interval 102.19-128.98), in RAP - 217.63 (95% confidence interval 173.31-261.94), and in CP - 539.43 (95% confidence interval 494.72-584.13) patients per 100,000 pancreatitis patients per year. There was a significant increase in the probability of LD with increasing number of pancreatitis recurrences and, for the same number of pancreatitis recurrences, LD was significantly more frequent after CP than RAP (hazard ratio 1.666 (95% confidence interval 1.322-2.098; p = <0.001)). CONCLUSIONS The frequency of LD increases from FAP to RAP to CP. While number of pancreatitis recurrences is a significant risk factor for development of LD, there is a higher probability of LD following CP than RAP even for the same number of recurrences. Interventions preventing pancreatitis and its progression may lower the burden of LD.

Abstract
BACKGROUND In an attempt to further improve liver allograft utilization and outcome in orthotopic liver transplantation (OLT), a variety of clinical scoring systems have been developed. Here we aimed to comparatively investigate the association of the Balance-of-Risk (BAR), Survival-Outcomes-Following-Liver-Transplant (SOFT), Preallocation-Survival-Outcomes-Following-Liver-Transplant (pSOFT), Donor-Risk-Index (DRI), and the Eurotransplant-Donor-Risk-Index (ET-DRI) scores with short- and long-term outcome following OLT. METHODS We included 338 consecutive patients, who underwent OLT in our institution between May 2010 and November 2017. For each prognostic model, the optimal cutoff values were determined with the help of the Youden-index and their diagnostic accuracy for 90-day post OLT-mortality and major postoperative complications was measured by the area under the receiver operating characteristic curve (AUROC). Patient- and graft survival were analyzed using the Kaplan-Meier method and the log-rank test. Morbidity was assessed using the Clavien-Dindo classification and the Comprehensive-Complication-Index. RESULTS BAR, SOFT, and pSOFT performed well above the conventional AUROC-threshold of 0.70 with good prediction of early mortality. Only BAR showed AUC>0.70 for both mortality and major morbidity. With the cutoffs of 14, 31, and 22 respectively for BAR, SOFT, and pSOFT, subgroup analysis showed significant differences (p<0.001) in morbidity and mortality, length of intensive care- and hospital-stay and early allograft dysfunction rates. Five-years patient survival was inferior in the high BAR, pSOFT, and SOFT groups. CONCLUSIONS Out of all scores tested, the BAR-score had the best value in predicting both 90-day morbidity and mortality after OLT showing the highest AUCs. The pSOFT and SOFT scores demonstrated an acceptable accuracy in predicting 90-day morbidity and mortality. The used BAR, SOFT, and pSOFT cutoffs allowed the identification of patients at risk in terms of five-year patient survival. The DRI and ET-DRI scores have failed to predict recipient outcomes in the present setting.

Abstract
BACKGROUND Incision and drainage of perianal sepsis has appreciable success in the immunocompetent population, but outcomes after incision and drainage in the immunosuppressed population are unknown. METHODS 13,666 patients (n = 930 immunosuppressed) undergoing incision and drainage of perianal sepsis between 2011 and 2015 in the American College of Surgeons National Surgical Quality Improvement Program were identified. The main outcomes were major morbidity, return to the operating room, and mortality. Multivariable analysis was performed for each outcome. RESULTS Sepsis was the most common postoperative complication. Preoperative immunosuppression was an independent risk factor for major morbidity (odds ratio [OR]: 1.6, p < 0.01), return to the operating room (OR: 1.9, p < 0.01), and mortality (OR: 2.6, p < 0.01). CONCLUSIONS Immunosuppression is an independent risk factor for major morbidity, return to the operating room, and mortality. With post-operative sepsis the most common complication, inpatient admission and extended duration antibiotic therapy is warranted in immunosuppressed patients.

Abstract
Among living donor liver transplantation recipients, the impact of educational levels on survival has rarely explored. Thus, the purpose of study is to analyze the survival rate differences across educational levels among recipients who underwent living donor liver transplantation.We retrospectively analyzed 2007 adult recipients who underwent living donor liver transplantation in a single large center. The educational level was divided into three categories: middle school or lower, high school, and college or higher. The primary outcome was all-cause mortality after living donor liver transplantation. Stratified log-rank test and Cox proportional hazard model were employed for statistical analysis.The incidence rates of all-cause mortality were 23.85, 20.19, and 18.75 per 1000 person-year in recipients with middle school or lower, high school, and college or higher education groups, respectively. However, the gender-stratified log-rank test has not shown a statistically significant difference (P = .3107). In the unadjusted model, hazard ratio (HR) was 1.02 [95% confidence interval (CI) = 0.79-1.33] in high school and 1.23 (95% CI = 0.93-1.64) and in middle school or lower educational level, respectively; In the full adjusted model, the HR of high school was 0.98 (95% CI = 0.75-1.28) and the HR of middle school or lower was 1.01 (95% CI = 0.74-1.37).Although study population of this study is large, we could not find significant survival rate differences by the levels of education. Social selection and high compliance rate might contribute to this result.

Abstract
Nonalcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic fatty liver disease. Our aim was to estimate the total economic burden of NASH and advanced NASH in the United States. We constructed lifetime Markov models for all stages of NASH and a separate model to specifically identify the increased burden of advanced NASH (fibrosis stage >3). The models comprised patients aged 18+, who moved through seven different health states. We used a lifetime horizon with 1-year cycles for each transition. Cohort size was estimated using US population data, and prevalence and incidence rates were obtained from the literature. Transition probabilities between states were derived from meta-analyses. Costs included inpatient, outpatient, professional services, emergency department, and drug costs, which were obtained from the Center for Medicare and Medicaid Services Fee Schedule 2017 and published data. All future costs were discounted at an annual rate of 3%. Our models estimated that there are 6.65 million adults (18+ years old) with NASH in the United States and that there were 232,000 incident cases in 2017. Lifetime costs of all NASH patients in the United States in 2017 will be $222.6 billion, and the cost of the advanced NASH population will be $95.4 billion. Conclusion: NASH, especially advanced NASH, is associated with high lifetime economic burden; in the absence of treatment, the total direct costs of illness for these patients will continue to grow, and these costs would be even greater if the societal costs are included.

Abstract
BACKGROUND Liver transplant is a potential cure for liver failure and hepatic malignancy but there are many techniques which have been described for vascular reconstruction. This study was to compare the prevalence of non-anastomotic biliary stricture and other surgical complications based on Clavien-Dindo scoring system, in initial portal reperfusion (sequential) versus simultaneous or initial artery reperfusion. DATA SOURCES Meta-analysis of published studies comparing the outcomes of both techniques was carried out. Data search was conducted across the major databases and studies were selected under the guidance of the Cochrane guidelines for systematic reviews and meta-analysis. RESULTS Seven studies were included to address the primary and the secondary outcomes. No statistical difference was found in the incidence of non-anastomotic biliary strictures (OR = 0.40; P = 0.14), regardless of reperfusion technique. The pooled estimate of the Clavien-Dindo grading of complications was not significantly different between the techniques, though Clavien-Dindo II complications were higher in the simultaneous or initial artery reperfusion group than the initial portal reperfusion group (OR = 2.73; P = 0.01). Similarly, there was no difference in the operative time, hospital stay and other outcomes addressed in this report. CONCLUSIONS The available evidence suggests that there is no significant difference demonstrated in the rate of non-anastomotic biliary strictures or other complications, between the two techniques, except for Clavien-Dindo II complications.

Abstract
In the face of a critical organ shortage in the Western world, various strategies are employed to expand the donor pool for orthotopic liver transplantation (OLT). Among them is the transplantation of organs from extended criteria donors, a valuable source of liver allografts, however, characterized by potential risks for post-OLT complications and inferior outcomes. In recent years, machine perfusion (MP) of the explanted donor liver as well as regional perfusion techniques has witnessed significant advancements. Here, we aim to discuss different modes of dynamic organ preservation in OLT. These include hypothermic and normothermic MP, hypothermic oxygenated machine perfusion (HOPE), controlled oxygenated rewarming as well as regional perfusion protocols. Over recent years, multiple feasibility trials have demonstrated the clinical prospects of MP. In the context of OLT using organs from extended criteria donors, MP has numerous advantages compared to conventional cold storage, some of which include the preservation and reconditioning of borderline transplantable organs and the viability assessment of high-risk donor allografts. This review aims to address the topic of liver allograft MP, highlighting particularly the current trends in clinical applications and future perspectives. Furthermore, different approaches of liver storage and reconditioning are reviewed in the context of ongoing research.

Abstract
Purpose The purpose of this study was to describe the long-term effects of stenting in patients with hepatic venous outflow obstruction (HVOO), who underwent living donor liver transplantation (LDLT). Methods Between January 2000 and December 2009, 622 adult patients underwent LDLT at our hospital, and of these patients, 21 (3.3%) were diagnosed with HVOO; among these patients, 17 underwent stenting. The patients were divided into early or late groups according to the time of their HVOO diagnoses (cutoff: 60 days after liver transplantation). Results The median follow-up period was 54.2 months (range, 0.5–192.4 months). Stent insertion was successful in 8 of 10 patients in the early group and 6 of 7 in the late group. The 5-year primary patency rates were 46% and 20%, respectively. In both groups, patients with recurrent HVOO at the beginning showed kinking confirmed by venography. Patients who carried their stents for more than 3 years maintained long-term patency. There was no significant difference in spleen size between groups; however, when the groups were compared according to whether they maintained patency, spleens tended to be smaller in the patency-maintained group. Conclusion Unlike stenosis, if kinking is confirmed on venography, stenting is not feasible in the long term for patients with LDLT.

BACKGROUND & AIMS Acute liver failure patients who meet poor prognostic criteria have high early mortality without emergency liver transplantation. A recent study however, reported that patients that survive spontaneously have a poorer outcome compared with patients undergoing transplantation. In this single centre study, we aimed to confirm or refute this observation. METHODS Early survivors (acute liver failure patients who survived 90 days after the ICU admission) were assessed for long-term outcomes in four distinctive cohorts, incorporating aetiology (Acetaminophen overdose or non-Acetaminophen overdose), and management strategy (conservative or liver transplantation). Chi Squared or Fisher test were used to compare outcomes among the four cohorts (P < 0.05) and Kaplan-Meier curve (Log Rank test) to represent cumulative survival. RESULTS Two hundred consecutive acute liver failure patients between 1990 and 2014 were included; mean age 38.3, ±12.8, male 70, 35%. 124/200 (62%) early survivors were identified; 13/124 (10.5%) acetaminophen patients underwent transplantation and 48/124 (38.7%) survived spontaneously; 36/124 (29.0%) non-acetaminophen underwent transplantation and 27/124 (21.8%) survived spontaneously. A total of 11/124 (8.9%) died subsequently (median survival 5.3± IQR 9.1), three spontaneous survivors and eight transplanted patients (P = 0.025); of the eight transplanted patients, six died of transplant related complications and two of suicide. CONCLUSION The results of this study suggest that although liver transplantation is a life-saving procedure for acute liver failure patients, they have a worse long-term outcome compared with spontaneous survivors. Novel therapies to increase the percentage of spontaneous survivors are urgently needed.

Abstract
Background Most liver transplant patients require Intensive Care Unit (ICU) care in the immediate postoperative period and some patients require readmission to the ICU before discharge from the hospital. A retrospective cohort study was conducted to identify risk factors for ICU readmission after liver transplantation. Material/Methods Adult patients who underwent living donor or deceased donor liver transplantation at Seoul National University Hospital between 2004 and 2015 were included. A retrospective review of baseline and perioperative factors that may be associated with ICU readmission was performed. Patients requiring ICU readmission during the hospitalization for LT (readmission group) were compared with patients who did not need ICU readmission (control group). A multivariable logistic regression analysis was performed to identify factors associated with ICU readmission after LT. Results Of the 1181 patients, 68 patients (5.8%) were readmitted to the ICU during the postoperative period after liver transplantation. Common causes of ICU readmission included postoperative bleeding, pulmonary complications, and sepsis. Multivariate analysis revealed that old age (OR 1.030 95%CI 1.002–1.059, p=0.035), pre-transplant chronic kidney disease (CKD) (OR 4.912 95%CI 2.556–9.439, p<0.001), intraoperative red blood cell (RBC) transfusion (OR 1.029 95%CI 1.008–1.050, p=0.007), new-onset atrial fibrillation in the ICU (OR 2.807 95%CI 1.087–7.249, p=0.033), and transplantation between 2011 and 2015 (vs. 2004–2010) were risk factors for ICU readmission after LT. Conclusions Old age, pre-transplant CKD, more intraoperative RBC transfusion, new-onset atrial fibrillation during ICU stay, and transplant period were identified as risk factors for ICU readmission.

Abstract
Purpose The aim of this study was to analyze survival outcomes in 1,000 consecutive liver transplantations (LTs) performed at a single institution from 1993 to April 2017. Methods The study population was divided into 2 groups based on donor type: deceased donor LT (DDLT; n = 181, 18.1%) and living donor LT (LDLT; n = 819; 81.9%), and into 3 periods based on the number of cases (first 300 cases, middle 300 cases, last 400 cases). Results Infection was the most common cause of death, accounting for 34.8% (95 of 273). Mortality due to hepatocellular carcinoma recurrence occurred most frequently between 1 and 5 years after transplantation. Mortality rate by graft rejection was highest between 5 and 10 years after transplantation. And mortality by de novo malignancy occurred most frequently after 10 years after transplantation. The patient survival rates for the entire population at 5 and 10 years were 74.7%, and 68.6%, respectively. There was no difference in survival rate between the LDLT and DDLT groups (P = 0.188). Cause of disease, disease severity, case period, and retransplantation had a significant association with patient survival (P = 0.002, P = 0.031, P = 0.003, and P = 0.024, respectively). Conclusion Surgical techniques and perioperative management for transplant patients have improved and undergone standardization. Controlling perioperative infection and managing patients with HCC as LT candidates will result in better outcomes.

Abstract
BACKGROUND Patients with non-resectable colorectal metastases are currently treated with chemotherapy. However, liver transplantation can increase the 5-year survival rate from 9 to 56 per cent if the cancer is confined to the liver. The aim of this study was to estimate the cost-effectiveness of liver transplantation for colorectal liver metastases. METHODS A Markov model with a lifetime perspective was developed to estimate the life-years, quality-adjusted life-years (QALYs), direct healthcare costs and cost-effectiveness for patients with non-resectable colorectal liver metastases who received liver transplantation or chemotherapy alone. RESULTS In non-selected cohorts, liver transplantation increased patients' life expectancy by 3·12 life-years (2·47 QALYs), at an additional cost of €209 143, giving an incremental cost-effectiveness ratio (ICER) of €67 140 per life-year (€84 667 per QALY) gained. In selected cohorts (selection based on tumour diameter, time since primary cancer, carcinoembryonic antigen levels and response to chemotherapy), the effect of liver transplantation increased to 4·23 life-years (3·41 QALYs), at a higher additional cost (€230 282), and the ICER decreased to €54 467 per life-year (€67 509 per QALY) gained. Given a willingness to pay of €70 500, the likelihood of transplantation being cost-effective was 0·66 and 0·94 (0·23 and 0·67 QALYs) for non-selected and selected cohorts respectively. CONCLUSION Liver transplantation was cost-effective but only for highly selected patients. This might be possible in countries with good access to grafts and low waiting list mortality.

Abstract
OBJECTIVES Newly developed, direct-acting antiviral therapy is effective in over 90% of cases to eradicate hepatitis C virus infection. Direct-acting antiviral therapy is also effective in liver transplant recipients with recurrent hepatitis C virus infection. However, hepatic function after sustained virologic response in transplant recipients is unknown. Here, we aimed to uncover the incidence of hepatic dysfunction in this patient group at our center. MATERIALS AND METHODS Our study included 40 consecutive (January 2014 to February 2016) and compliant posttransplant recipients who achieved sustained viral response from direct-acting antiviral therapy. Patients were investigated for incidence and causes of hepatic dysfunction. RESULTS In our patient group, 4 (10%) experienced hepatic dysfunction with stable baseline immunosuppression, with 2 having drastic increases in alanine aminotransferase at 15 and 32 weeks after direct-acting antiviral therapy. Biopsies showed hepatitis, and both patients were treated with hydrocortisone, which increased their baseline immunosuppression. The 3rd patient had an increase in bilirubin at 21 weeks posttherapy, with biopsy showing macrovascular steatosis. The 4th patient had a rapid increase in bilirubin at 7 weeks after direct-acting antiviral therapy, with biopsy showing significant duct loss. CONCLUSIONS During the study period, 10% of patients experienced hepatic dysfunction after sustained viral response. Presumed causative factors included partial immune reconstitution and nonalcoholic fatty liver disease.

Abstract
Background/Aims With improvements in the survival of liver transplantation (LT) recipients, the focus is shifting to patient quality of life (QOL), and employment is an important factor in aiding the social reintegration of LT patients. This study aims to evaluate the current employment status of liver graft recipients and various factors that may hinder reemployment. Methods Fifty patients above age 18 who underwent either living or deceased donor LT at a single center from March 2009 to July 2016 were interviewed during their visit to the outpatient clinic. The internally developed questionnaire consisted of 10 items. The Karnofsky Performance Scale and EQ-5D were used to evaluate patient function and QOL. Results A total of 25 (50%) patients returned to work after transplantation (the working group), and 21 (84%) patients in the working group returned to work within the first year after transplantation. In the non-working group (n=25), 17 (68%) answered that their health was the reason for unemployment. Fatigue and weakness were the most frequent symptoms. Conclusions The data shows that as many as 50% of total patients returned to work after receiving LT. Fatigue and weakness were the most common complaints of the unemployed group, and resolving the causes of these symptoms may help to increase the employment rate.

Abstract
BACKGROUND Liver transplantation (LT) in elderly recipients is controversially discussed in the literature with only little data on long-term outcome available. We aimed to evaluate the safety and efficiency of LT in elderly recipients (>65 years). METHODS Between 1989-2016, 139 patients >65 years-old were listed for liver transplantation, and 76 (55%) were transplanted. Patient outcome and characteristics were evaluated separately for the time period before (1989-2004) and after (2005-2016) MELD-implementation. Post-transplant outcome was compared between the elderly cohort and LT-recipients aged 18-65 years (n = 1395). RESULTS Overall survival of patients >65 years was better in the MELD-era compared to the earlier period (1- and 5-year-survival: 73%, 60% vs. 69%, 37%, respectively; p = 0.055). The main differences between the two groups included higher recipient age (p = 0.001) and BMI (p = 0.001), higher donor age (p < 0.001), less need of intraoperative red blood cells (p = 0.008) and a lower number of postoperative rejections (p = 0.03) after 2004. Comparing the overall survival of patients transplanted in the MELD-era aged 18-65 years vs. >65 years displayed comparable 1- and 5 year-survival rates (81%, 68% vs. 73% and 60%, respectively, p = 0.558). CONCLUSION In the modern era, outcome of patients receiving LT with >65 years is comparable to <65 year-old patients. After careful evaluation, patients >65 years old should be considered for LT.

Abstract
AIM To compare trends in donor/recipient characteristics and outcomes using four period cohorts of liver transplant recipients from 1990 to 2009. METHODS Seventy thousand three hundred and seventy-seven adult first-time recipients of whole-organ deceased-donor liver grafts from 1990 to 2009 were followed up until September 2013. Four periods based on transplantation dates were considered to account for developments in transplantation. Descriptive statistics were used to describe donor/recipient characteristics and transplant outcomes. Statistical comparisons between periods were performed using χ2/Fischer's exact test (categorical variables) and t-tests/Mann-Whitney U test (continuous variables). Univariate descriptive statistics/survival data were generated using Kaplan-Meier curves. Cox Proportional Hazards models were used for regression analyses of patient and graft survival. RESULTS Mean age (years), body mass index (kg/m2), and the proportion of males were, respectively, 39.1 (± 17.4), 25.9 (± 5.7) and 60.3 for donors, and 51.3 (± 10.5), 27.7 (± 5.6), and 64.4 for recipients. Donor and transplantation rates differed between racial/ethnic groups. Median (Q1-Q3) cold and warm ischemia, waitlist, and hospital stay times were 8 (6.0-10.0) h and 45 (35-59) min, 93 (21-278) d, and 12 (8-20) d. Total functional assistance was required by 8% of recipients at wait-listing and 13.4% at transplantation. Overall survival at 1, 3, 5, 10, 15, and 20 years was 87.3%, 79.4%, 73.6%, 59.8%, 46.7%, and 35.9%, respectively. The 2005-2009 cohort had better patient and graft survival than the 1990-1994 cohort overall [HR 0.67 (0.62-0.72) and 0.66 (0.62-0.71)] and at five years [HR 0.73 (0.66-0.80) and 0.71 (0.65-0.77)]. CONCLUSION Despite changes in donor quality, recipient characteristics, and declining functional status among transplant recipients, overall patient survival is superior and post-transplant outcomes continue to improve.

Abstract
Objective This study was performed to identify risk factors for acute cellular rejection after liver transplantation (LT). Methods Consecutive LT recipients who underwent surgery in our institution from 2002 to 2015 were retrospectively evaluated. Results In total, 176 patients were eligible for statistical analysis. During a mean observation period of 61.1 ± 36.3 months, 43 episodes of acute rejection were evident. Of these, 34 (79.0%) were responsive to methylprednisolone, 3 (7.0%) were treated by adjusting the dosage of immunosuppressive agents, and 6 (14.0%) were methylprednisolone-resistant and treated using anti-thymocyte globulin. Biliary complications (odds ratio [OR] = 4.89, 95% confidence interval [CI] = 2.00-11.98); donor-negative, recipient-positive CMV mismatch (OR = 9.88, 95% CI = 1.18-82.36); sex mismatch (OR = 3.16, 95% CI = 1.31-8.10); and sex mismatch with a female donor (OR = 3.00, 95% CI = 1.10-7.58) were identified as significant risk factors for acute graft rejection after LT. Conclusion In patients who develop acute cellular rejection after LT, biliary complications should be evaluated as a potential cause. Most acute rejections after LT respond to bolus corticosteroid therapy.
