Abstract
For end-stage liver disease in children, living donor liver transplantation (LDLT) is often the important standard curative treatment. However, there is a lack of research on early recovery of graft function after pediatric LDLT. This is a single-center, ambispective cohort study. We collected the demographic and clinicopathological data of donors and recipients, and determined the risk factors of postoperative delayed recovery of hepatic function (DRHF) by univariate and multivariate Logistic analyses. 181 cases were included in the retrospective cohort and 50 cases in the prospective cohort. The incidence of DRHF after LDLT in children was 29.4%, and DRHF could well evaluate the early recovery of graft function after LDLT. Through Logistic analyses and AIC score, preoperative liver function of donors, ischemia duration level of the liver graft, Ln (Cr of recipients before operation) and Ln (TB of recipients on the 3rd day after operation) were predictive indicators for DRHF after LDLT in children. Using the above factors, we constructed a predictive model to evaluate the incidence of postoperative DRHF. Self-verification and prospective internal verification showed that this prediction model had good accuracy and clinical applicability. In conclusion, we pointed many risk factors for early delayed recovery of graft function after LDLT in children, and developed a visual and personalized predictive model for them, offering valuable insights for clinical management.

Abstract
BACKGROUND Liver transplantation (LT) is typically performed at specialized, high-volume centers. However, some smaller centers also offer liver transplantation services, but their outcomes and safety have been a subject of debate. To overcome these difficulties, we tried to build a Catholic Medical Center (CMC) network to share our experiences and overcome the lack of volume. In this study, we reviewed the overall outcome of patients undergoing LT at a small-volume procedure center, with a focus on patient and graft survival rates. METHODS Between July 2014 and September 2021, 60 adults underwent LT at Bucheon Saint Mary's Hospital. The overall outcomes were analyzed in terms of perioperative outcomes, complications, and overall survival rate. In addition, the patients were divided into a benign end-stage liver disease (ESLD) group (n = 44) and a hepatocellular carcinoma (HCC) group (n = 16). The baseline characteristics, perioperative outcomes, complications, and overall survival rate were analyzed between the 2 groups. RESULTS Of a total of 60 LT, living donor liver transplantation (LDLT) was 26, and deceased donor liver transplantation was 34. LDLT was 14 (31.8%) in the ESLD group and 12 (75.0%) in the HCC group. The overall 1-year, 3-year, and 5-year survival rates were 86.7%, 79.7%, and 77.7%, respectively. The survival difference was not statistically significant (P = .214) between the 2 groups. CONCLUSION We suggest that with appropriate patient selection and adequate resources, LT can be safely performed at smaller centers with the assistance of the CMC network, thus expanding access to this life-saving procedure.

Abstract
We introduce and documentthe first case of dual-graft living donor liver transplant, at the King Fahad Specialist Hospital in Dammam, Kingdom of Saudi Arabia, in which both a full right lobe and a left lateral segment graft were used. Our patient, a 63-year-old male, was diagnosed with nonalcoholic steatohepatitis cirrhosis and hepatocellular carcinoma involving segment 7 and selected for living donor liver transplant. Donor selection, graft volume assessment, surgical planning, procurement, and implantation of the dual grafts were meticulously executed. The first donor had an estimated right lobe volume of 639 mL, yielding an estimated graft-to-recipient weight ratio of 0.68. A liver biopsy revealed 3% macrosteatosis.The second donor's contribution comprised a left lateral segment volume of 280 mL.The decision was made for dual-graft liver transplant. With both grafts, the volume totaled 919 mL, representing graft-torecipient weight ratio of 0.98. Surgical techniques involved anastomoses of hepatic veins, portal veins, arteries, and biliary reconstruction. Both donors and the recipient were closely monitored posttransplant. After the procedure, both donors recovered swiftly and were discharged 4 days postoperation. The recipient experienced a smooth postoperative course, spending 4 days in the intensive care unit and discharged on day 26 posttransplant. This pioneering dual-graft living donor liver transplant showed successful outcomes and highlighted the potential of this approach to expand the limited donor pool, particularly in regions relying predominantly on living donors, like Saudi Arabia. This innovative surgical technique offers a promising solution to address the growing demand for liver transplants while ensuring safety for individual donors and maintaining acceptable recipient outcomes. Further exploration and adoption of dual-graft liver transplant could significantly affectthe field of livertransplant globally.

Abstract
OBJECTIVE The aim of this study was to identify safety and risk factors of living donor after pure laparoscopic donor right hepatectomy in a Korean multicenter cohort study. BACKGROUND Pure laparoscopic donor right hepatectomy is not yet a standardized surgical procedure due to lack of data. METHODS This retrospective study included 543 patients undergoing PLRDH between 2010 and 2018 in 5 Korean transplantation centers. Complication rates were assessed and multivariate logistic regression analyses were performed to identify risk factors of open conversion, overall complications, major complications, and biliary complications. RESULTS Regarding open conversion, the incidence was 1.7% and the risk factor was body mass index >30 kg/m 2 [ P =0.001, odds ratio (OR)=22.72, 95% CI=3.56-146.39]. Rates of overall, major (Clavien-Dindo classification III-IV), and biliary complications were 9.2%, 4.4%, and 3.5%, respectively. For overall complications, risk factors were graft weight >700 g ( P =0.007, OR=2.66, 95% CI=1.31-5.41), estimated blood loss ( P <0.001, OR=4.84, 95% CI=2.50-9.38), and operation time >400 minutes ( P =0.01, OR=2.46, 95% CI=1.25-4.88). For major complications, risk factors were graft weight >700 g ( P =0.002, OR=4.01, 95% CI=1.67-9.62) and operation time >400 minutes ( P =0.003, OR=3.84, 95% CI=1.60-9.21). For biliary complications, risk factors were graft weight >700 g ( P =0.01, OR=4.34, 95% CI=1.40-13.45) and operation time >400 minutes ( P =0.01, OR=4.16, 95% CI=1.34-12.88). CONCLUSION Careful donor selection for PLRDH considering body mass index, graft weight, estimated blood loss, and operation time combined with skilled procedure can improve donor safety.

High-resolution MR imaging with gadoxetate disodium for the comprehensive evaluation of potential living liver donors. Liver Transpl 2023; 29:497-507. [PMID: 36738083 DOI: 10.1097/lvt.0000000000000099] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2022] [Accepted: 12/21/2022] [Indexed: 02/05/2023]
Abstract
OBJECTIVE Several major transplantation centers have used composite multimodality evaluation for the preoperative evaluation of potential living liver donors. This approach can be time-consuming and, although rare, can cause complications. We aimed to demonstrate the clinical feasibility of our comprehensive preoperative MR protocol for the preoperative assessment of living liver donor candidates instead of composite multimodality evaluation. MATERIALS AND METHODS Thirty-five consecutive living liver donor candidates underwent multiphasic liver CT and comprehensive donor protocol MR examinations for preoperative evaluation in a single large-volume liver transplantation (LT) center. Three blinded abdominal radiologists reviewed the CT and MR images for vascular and biliary variations. The strength of agreement between CT and MR angiography was assessed using the kappa index. The detection rate of biliary anatomical variations was calculated. The sensitivity and specificity for detecting significant steatosis (>5%) were calculated. The estimated total volume and right lobe volumes measured by MR volumetry were compared with the corresponding CT volumetry measurements using the intraclass correlation coefficient (ICC). RESULTS Among the 35 patients, 26 underwent LT. The measurement of agreement showed a moderate to substantial agreement between CT and MR angiography interpretations (kappa values, 0.47-0.79; p < 0.001). Combining T2-weighted and T1-weighted MR cholangiography techniques detected all biliary anatomical variations in 9 of the 26 patients. MR-proton density fat fraction showed a sensitivity of 100% (3/3) and a specificity of 91.3% (21/23) for detecting pathologically determined steatosis (>5%). MR volumetry reached an excellent agreement with CT volumetry (reviewers 1 and 2: ICC, 0.92; 95% CI, 0.84-0.96). CONCLUSION Our one-stop comprehensive liver donor MR imaging protocol can provide complete information regarding hepatic vascular and biliary anatomies, hepatic parenchymal quality, and liver volume for living liver donor candidates and can replace composite multimodality evaluation.

Abstract
BACKGROUND AND AIMS There are no established practice guidelines for treating hepatocellular carcinoma (HCC) in patients with Child-Turcotte-Pugh (CTP) class B liver function. To evaluate the impact of various initial treatment modalities on these patients, we conducted a nationwide registry study in Korea. MATERIALS AND METHODS Treatment patterns and overall survival (OS) of patients with HCC and CTP class B according to initial treatment modalities in each Barcelona Clinic Liver Cancer (BCLC) stage were analysed using data from the Korean Primary Liver Cancer Registry between 2008 and 2016. Initial treatment modalities were categorized as standard, alternative treatment and supportive care only, referring to the 2018 BCLC guidelines, irrespective of liver function. RESULTS Of the 2318 newly diagnosed Korean patients with HCC and CTP class B, 29.7%, 60.3% and 15.6% of patients in BCLC stages A, B and C, respectively, underwent standard treatment. Adjusted OS hazard ratios of alternative treatment referring to standard treatment were 1.55 (95% confidence interval [CI], 1.25-1.94; p < .001) in BCLC-A, 0.82 (95% CI, 0.43-1.56; p = .550) for curative alternative treatment, 1.89 (95% CI, 0.97-3.68; p = .059) for non-curative alternative treatment in BCLC-B, 0.40 (95% CI, 0.28-0.56; p < .001) for curative alternative treatment, 0.84 (95% CI, 0.69-1.02; p = .076) for non-curative alternative treatment for BCLC-C. CONCLUSION Regardless of BCLC stages, chemoembolization was conducted the most among patients with CTP class B. Treatment in line with the BCLC treatment algorithm resulted in favourable OS outcomes, except for those with BCLC stage C, as systemic therapy showed poor OS.

Abstract
The international practice of transplant in the pediatric population is heterogenous. Global trends in pediatric transplant activity are increasing, with diffusion of transplant activities into developing and emerging economies. There have been impacts of the COVID-19 pandemic which have in the earlier part of the pandemic caused a decrease in the number of transplants. While deceased donor programs are well established in advanced economies, emerging and developing countries rely heavily on live donor programs. Prioritization of organs for children exists in different forms throughout the world. Pediatric transplantation as a sub-specialty is young but growing around the world with a need to train surgeons and physicians in this discipline. Outreach efforts with multi-national and multi-institutional partnerships have enabled resource poor countries to establish new transplant programs for children. Further international collaboration, good quality data collection and audit, prospective research and ongoing mentorship and education are needed to further improve outcomes of all children receiving solid organ transplants.

Abstract
Living donor liver transplantation (LDLT) is a significant advancement for the treatment of children with end-stage liver disease given the shortage of deceased donors. The ultimate goal of pediatric LDLT is to achieve complete donor safety and zero recipient mortality. We conducted a retrospective, single-center assessment of the outcomes as well as the clinical factors that may influence graft and patient survival after primary LDLTs performed between 1994 and 2020. A Cox proportional hazards model was used for multivariate analyses. The trends for independent prognostic factors were analyzed according to the following treatment eras: 1, 1994 to 2002; 2, 2003 to 2011; and 3, 2012 to 2020. Primary LDLTs were performed on 287 children during the study period. Biliary atresia (BA; 52%), acute liver failure (ALF; 26%), and monogenic liver disease (11%) were the leading indications. There were 45 graft losses (16%) and 27 patient deaths (7%) in this population during the study period. During era 1 (n = 81), the cumulative survival rates at 1 and 5 years after LDLT were 90.1% and 81.5% for patients and 86.4% and 77.8% for grafts, respectively. During era 2 (n = 113), the corresponding rates were 92.9% and 92% for patients and 89.4% and 86.7% for grafts, respectively. During era 3 (n = 93), the corresponding rates were 100% and 98.6% for patients and 98.9% and 95.4% for grafts, respectively. In the multivariate analyses, primary diagnosis ALF, bloodstream infection, posttransplant lymphoproliferative disease, and chronic rejection were found to be negative prognostic indicators for patient survival. Based on generalized care guidelines and center-oriented experiences, comprehensive advances in appropriate donor selection, refinement of surgical techniques, and meticulous medical management may eventually realize a zero-mortality rate in pediatric LDLT.

Abstract
Liver transplantation is the only curative treatment for end-stage liver disease. Unfortunately, the scarcity of donor organs and the increasing pool of potential recipients limit access to this life-saving procedure. Allocation should account for medical and ethical factors, ensuring equal access to transplantation regardless of recipient's gender, race, religion, or income. Based on their short-term prognosis prediction, model for end-stage liver disease (MELD) and MELD sodium (MELDNa) have been widely used to prioritize patients on the waiting list for liver transplantation resulting in a significant decrease in waiting list mortality/removal. Recent concern has been raised regarding the prognostic accuracy of MELD and MELDNa due, in part, to changes in recipients' profile such as body mass index, comorbidities, and general condition, including nutritional status and cause of liver disease, among others. This review aims to provide a comprehensive view of the current state of MELD and MELDNa advantages and limitations and promising alternatives. Finally, it will explore future options to increase the donor pool and improve donor-recipient matching.

Abstract
BACKGROUND The effect of pretransplant hepatorenal syndrome (HRS) on the outcomes of living-donor liver transplantation (LDLT) recipients with special reference to the recovery of HRS before LDLT was investigated. METHODS The rate of HRS was 43.9% (125/285) among the cohort, and the subjects were divided into 3 groups: those without HRS (No-HRS group, n=160), those with HRS but recovered following pretransplant renal function restoration treatment (Responders group, n=55), and those with persistent HRS (Non-responders group, n=70). RESULTS While the 1-, 3-, and 5-year patient survival rates were comparable between those with and without HRS (89.6%, 84.7%, and 84.7% vs. 95.6%, 92.2%, and 87.5%), the cumulative incidence of the development of posttransplant chronic kidney disease (CKD) was significantly higher in those with HRS (p<0.001). In addition, there was a significant difference between Responders and Non-responders in the development of CKD (p=0.01). In the Cox regression model, Non-responders (p=0.032, HR 1.79 [95% C.I. 1.05-3.03]) and recipient age (p=0.014, HR 1.62 [95% C.I. 1.10-2.37]) were independent predictors for the development of CKD after LDLT. CONCLUSION LDLT is safe and effective for patients with HRS, and CKD progression could be reduced among those with HRS who responded to renal restoration treatment.

The Impact of Primary Liver Disease and Social Determinants in a Mixed Donor Liver Transplant Program: A Single-Center Analysis. Liver Transpl 2021; 27:1733-1746.

Abstract
Organ allocation in liver transplantation (LT) remains imperfect. Periodic center reviews ensure programs transparently evaluate the impact of practice on access to transplantation, reflecting, in particular, patient (primary disease, social determinants) and program (deceased versus live donation) factors. Adult Ontario residents waitlisted for first LT at Toronto General Hospital from November 2012 to May 2019 were reviewed. Analyses were performed between distance to transplant center, income, education level, population density and primary liver disease, with LT, deceased donor liver transplant (DDLT), living donor liver transplant (LDLT), and delisting. Of 1735 listed patients, 549 were delisted (32%), while 1071 were transplanted (62%), with 819 DDLT recipients (76%) and 252 LDLT recipients (24%), while 115 (7%) remained actively listed at data census. On univariate analysis, DDLT recipients lived 30% closer (median 39.7 versus 60.6 km; P < 0.001), lived in more populous areas (median 8501.0 versus 6868.5 people in a 1-km radius; P < 0.001), and resided in households that annually earned 10% less (median $92,643.17 versus $102,820.89 Canadian dollars; P < 0.001) compared with LDLT recipients. These findings with population density and income differences between DDLT versus LDLT receival remained significant on multivariate modeling even when accounting for primary liver disease. Primary liver disease was a statistically significant factor on multivariate analyses in LT receival (P = 0.001) as well as DDLT versus LDLT receival (P < 0.001). Of patients listed for end-stage liver disease, more patients with autoimmune cholestatic liver diseases received LDLT (34%-41%) than DDLT (27%-30%); this contrasted with patients with noncholestatic diseases LDLT (8%-19%) versus DDLT (37%-59%) receival (P < 0.001). Review of transplant allocation in a large mixed-donor North American liver transplant program demonstrates how patient social determinants and primary liver disease etiology continue to be significantly associated with ultimate transplantation.

Abstract
BACKGROUND The volume-outcome relation for complex surgical procedures such as living donor liver transplantation (LDLT) generally favors high volume (HV) centers. It is important for low to medium volume (MV) centers to evaluate their centers' performance against HV centers to allow early detection and correction of potential systemic issues. There is a dearth of national and international comprehensive registries for LDLT that may allow reasonable risk-adjusted comparisons for benchmarking. This study aims to evaluate the LDLT program by comparing our center's performance against HV centers of the Adult-to-Adult Living Donor Liver Transplantation cohort. STUDY DESIGN Patient outcomes from a MV transplant center were compared with 11 HV transplant centers from the Adult-to-Adult Living Donor Liver Transplantation cohort. Outcomes evaluated included length of hospital stay, same admission mortality, 90-day mortality, and overall survival. RESULTS A total of 1381 patients were analzyed. HV 1 to 4, 6, 8, 9, and 11 centers had a shorter median length of hospital stay compared with the MV center (All Dunnett corrected P values all less than .05). HV 9 and 11 centers had lower same admission mortality compared with the MV center (Dunnett corrected P = .023 and .015). After adjusting for other significant predictors, the MV center had comparable 90-day mortality rates and overall survival rates to all HV centers. CONCLUSION This benchmarking exercise has demonstrated that the limitation of low institutional case volume can be overcome with a protocol-based framework to implement a safe LDLT program. This framework presented can be adopted for developing programs.

Abstract
BACKGROUND Biliary complications, especially bile leaks, are an important cause of early postoperative morbidity and, rarely, mortality after liver transplant. The risk is higher in living donor liver transplant (LDLT) compared to deceased donor liver transplant (DDLT). Attempts to reduce bile leaks have included refinements in the biliary anastomosis technique and use of various external and internal stents, with inconsistent benefits. Recent availability and successful use of the absorbable Archimedes stent has prompted its intrabiliary placement across the anastomosis. METHODS In this retrospective study, we analyzed the data of 20 adult patients who underwent a liver transplant with duct-to-duct biliary anastomosis using the Archimedes stent. Both DDLT and LDLT were performed using cava-preserving hepatectomy followed by standard implantation methods. Duct-to-duct biliary anastomosis was performed in all cases using interrupted sutures with extracorporeal knots over an absorbable intrabiliary stent. In addition to standard postoperative care, patients were monitored for bile leak. RESULTS Nine DDLTs had a single anastomosis over a 10-Fr stent. Out of 11 LDLT patients, 7 had a single anastomosis and 4 patients had 2 anastomoses, all over a 6-Fr stent. Two patients died, 1 as a result of graft primary nonfunction and another because of multidrug-resistant pneumonia. One patient had ascending cholangitis owing to stent migration in the duodenum. This episode was treated with endoscopic stent removal and appropriate antibiotics, with good recovery. None of the other patients had bile leaks, biloma, or stent-related complications. CONCLUSIONS Archimedes internal absorbable biliary stents can be safely used in both living and deceased donor liver transplants to prevent bile leaks.

Abstract
BACKGROUND The aim of this study was to verify the safety and feasibility of our selection criteria for middle hepatic vein (MHV) reconstruction in living donor liver transplantation (LDLT) using right lobe grafts. METHODS A total of 153 LDLTs were performed using right lobe grafts in a tertiary hospital from 2006 to 2016. Among them, 52 cases without MHV reconstruction were compared with 101 recipients who underwent LDLT using right lobe graft with MHV reconstruction. Both groups were compared regarding indications for reconstruction, short-term and long-term complications, operative details, and outcomes. RESULTS The two groups differed only in cold ischemic time (108.19 ± 49.81 minutes vs 146.37 ± 58.74 minutes) preoperatively. Short-term posttransplant outcomes, long-term overall survival, and long-term disease-free survival showed no significant differences between the 2 groups. After propensity score matching for both groups with and without MHV reconstruction to eliminate selection bias, the 2 groups were comparable. CONCLUSIONS We found that our selection criteria for performing MHV reconstruction in LDLT using right lobe graft were feasible and safe. A routine MHV reconstruction is not necessary if the right lobe graft graft-to-recipient weight ratio is ≥1.0, right hepatic vein draining territory volume is ≥0.8, and recipient Model for End-Stage Liver Disease score is <20.

Abstract
Background/Aims Biliary complications including biliary strictures and bile leaks are the most common complications that occur after liver transplantation (LT). Endoscopic treatment with endoscopic retrograde cholangiography (ERC) is considered the first-line treatment, and percutaneous transhepatic cholangiography (PTC) can serve as an alternative or rescue therapy. However, nationwide clinical data on the frequency of ERC and PTC following LT have not yet been investigated. Methods Using the nationwide claims database, we investigated patients who underwent LT between 2012 and 2014 in Korea and followed them until 2015. We analyzed the prevalence and characteristics of patients and biliary procedures, including ERC and PTC implemented after LT. Results A total of 3,481 patients underwent LT during the 3-year study period. Among them, 3.0% of patients underwent biliary intervention postoperatively during the same hospitalization period, and 21.4% of patients received biliary intervention later on after initially being discharged from the hospital following LT. A total of 16.9% and 12.1% of patients underwent ERC and PTC after LT, respectively. The median period from LT to the first biliary intervention was 7.8 months (interquartile range, 3.5 to 14.6 months), and these patients underwent an average of 3.2±2.8 biliary procedures during the follow-up period. Patients undergoing living donor LT were more than twice as likely to undergo biliary procedures as those undergoing deceased donor LT (25.5% vs 12.1%). Conclusions Approximately one-fourth of patients in Korea who underwent LT subsequently underwent ERC or PTC. Compared with deceased donor LT patients, those undergoing living donor LT underwent more biliary interventions and were more difficult to treat.

Abstract
BACKGROUND/AIMS To analyze the incidence and risk factors of outcomes after liver transplantation (LT) in the Korean population. METHODS This study analyzed data from the liver cohort of Korean Organ Transplantation Registry (KOTRY) who had LT between May 2014 and December 2017. Study measures included the incidence of post-LT outcomes in recipients of living donor LT (LDLT) and deceased donor LT (DDLT). Cox multivariate proportional hazards model was used to determine the potential risk factors predicting the outcomes. RESULTS A total of 2,563 adult recipients with LT (LDLT, n=1,956; DDLT, n=607) were included, with mean±standard deviation age of 53.9±8.9 years, and 72.2% were male. The post-LT outcomes observed in each LDLT and DDLT recipients were death (4.0% and 14.7%), graft loss (5.0% and 16.1%), rejection (7.0% and 12.0%), renal failure (2.7% and 13.8%), new onset of diabetes (12.5% and 15.4%), and hepatocellular carcinoma (HCC) recurrence (both 6.7%). In both LDLT and DDLT recipients, the most common post-LT complications were renal dysfunction (33.6% and 51.4%), infection (26.7% and 48.4%), and surgical complication (22.5% and 23.9%). Incidence of these outcomes were generally higher among recipients of DDLT than LDLT. Multivariate analysis indicated recipient age and DDLT as significant risk factors associated with death and graft loss. DDLT and ABO incompatible transplant were prognostic factors for rejection, and HCC beyond Milan criteria at pre-transplant was a strong predictor of HCC recurrence. CONCLUSION This study is a good indicator of the post-LT prognosis in the Korean population and suggests a significant burden of post-LT complications.

Abstract
BACKGROUND Chronic hepatitis B is the most common cause of liver cirrhosis in South Korea. However, alcoholic liver disease has shown an increasing trend. Although the clinical implications surrounding liver cirrhosis have been changing over the years, few studies have recently examined cirrhosis epidemiology. Therefore, we aimed to investigate changes in liver cirrhosis etiology and severity in Korea. METHODS We retrospectively reviewed 16,888 records of cirrhotic patients from six tertiary hospitals in Korea from 2008 to 2017. Continuous and non-continuous variables were processed via linear and Poisson regression, expressed as beta (B) coefficients and as exponentiated values of coefficients (Exp[B]), respectively. RESULTS Chronic hepatitis B showed a decreasing trend (Exp[B] = 0.975, P < 0.001), whereas alcohol showed an increasing trend (Exp[B] = 1.013, P = 0.003), occupying the most common etiology in 2017. The Child-Turcotte-Pugh (CTP) score and decompensated liver cirrhosis prevalence did not change over the 10-year period. The incidence of variceal bleeding, severe ascites, hepatic encephalopathy, and spontaneous bacterial peritonitis significantly decreased from 12.3% to 7.7%, 7.8% to 4.1%, 1.0% to 0.5%, and 1.9% to 1.1%, respectively (P < 0.05 for all). In the subgroup analysis, the chronic hepatitis B group showed improving CTP scores (B = -0.025, P < 0.001) and decreasing decompensated liver cirrhosis rates (Exp[B] = 0.977, P = 0.016), whereas the alcohol group demonstrated increasing CTP class C (Exp[B] = 1.031, P = 0.005) and model for end-stage liver disease scores (B = 0.081, P = 0.005) over 10 years. CONCLUSION The chronic hepatitis B group exhibited improved results, whereas the alcohol group still presented poor liver functions and outcomes. Future national policies and systematic approaches addressing the incidence, prevention, and treatment of alcoholic liver cirrhosis are indispensable.

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
BACKGROUNDS/AIMS Simultaneous liver and kidney transplantation (SLKT) has been established as the treatment of choice for patients with concurrent end-stage liver and end-stage kidney diseases. The objective of this study was to analyze the nationwide incidence of SLKT in Korea and the outcomes of SLKT in a high-volume transplant center. METHODS Databases of the Korean Network for Organ Sharing (KONOS) and Asan Medical Center from 2000 to 2019 were retrospectively reviewed to determine the incidence of SLKT. RESULTS During 20 years from 2000 to 2019, deceased donor SLKT was performed for 38 cases in the KONOS database. The proportion of deceased donor SLKT was 0.6% (20 of 3333) before adoption of MELD score, which was significantly increased to 1.2% (18 of 1524) after the adoption of MELD score (p=0.034). In our institution, there were 11 cases of SLKT (2 cases with deceased donors and 9 cases with living donors). SLKT accounted for 0.2% (11 of 6468) of total liver transplantation volume. During follow-up, five patients died due to hepatocellular carcinoma recurrence (n=2), infection (n=2), or unknown cause (n=1). The 1-year and 10-year overall patient survival rates were 90.9% and 81.8%, respectively. CONCLUSIONS Results of this study revealed that the incidence of deceased donor SLKT was very low. An increase of such incidence is not anticipated unless the number of deceased donors is markedly increased. Currently, sequential living donor liver transplantation and kidney transplantation with deceased or living donors are mainstays of transplantation rather than SLKT in our institution.

Abstract
PURPOSE The aim of the study is to predict the rate of liver regeneration in recipients after living-donor liver transplantation using preoperative CT texture and shape analysis of the future graft. METHODS 102 donor-recipient pairs who underwent living-donor liver transplantation using right lobe grafts were retrospectively included. We semi-automatically segmented the future graft from preoperative CT. The volume of the future graft (LVpre) was measured, and texture and shape analyses were performed. The graft liver was segmented from postoperative follow-up CT and the volume of the graft (LVpost) was measured. The regeneration index was defined by the following equation: [(LVpost-LVpre)/LVpre] × 100(%). We performed a stepwise, multivariate linear regression analysis to investigate the association between clinical, texture and shape parameters and the RI and to make the best-fit predictive model. RESULTS The mean regeneration index was 47.5 ± 38.6%. In univariate analysis, the volume of the future graft, energy, effective diameter, surface area, sphericity, roundnessm, compactness1, and grey-level co-occurrence matrix contrast as well as several clinical parameters were significantly associated with the regeneration index (p < 0.05). The best-fit predictive model for the regeneration index made by multivariate analysis was as follows: Regeneration index (%) = 127.020-0.367 × effective diameter - 1.827 × roundnessm + 47.371 × recipient body surface area (m2) + 12.041 × log(recipient white blood cell count) (× 103/μL)+ 18.034 (if the donor was female). CONCLUSION The effective diameter and roundnessm of the future graft were associated with liver regeneration. Preoperative CT texture analysis of future grafts can be useful for predicting liver regeneration in recipients after living-donor liver transplantation.

Abstract
BACKGROUND Since the first success in an adult patient, living donor liver transplantation (LDLT) has become an universally used procedure. Small-for-size syndrome (SFSS) is a well-known complication after partial LT, especially in cases of adult-to-adult LDLT. The definition of SFSS slightly varies among transplant physicians. The use of a partial liver graft has risks of SFSS development. Persistent portal vein (PV) hypertension and PV hyper-perfusion after LT were identified as the main factors. Hence, various approaches were explored to modulate PV flow and decrease PV pressure in order to alleviate this syndrome. Herein, the definition, clinical symptoms, pathophysiology, basic research, as well as preventive and treatment strategies for SFSS are reviewed based on an extensive review of the literature and on our own experiences. DATA SOURCES The articles were collected through PubMed using search terms "liver transplantation", "living donor liver transplantation", "living liver donation", "partial graft", "small-for-size graft", "small-for-size syndrome", "graft volume", "remnant liver", "standard liver volume", "graft to recipient body weight ratio", "sarcopenia", "porcine", "swine", and "rat". English publications published before March 31, 2020 were included in this review. RESULTS Many transplant surgeons performed PV flow modulation, including portocaval shunt, splenic artery ligation and splenectomy. With these techniques, patient outcome has been improved even when using a "small" graft. Other factors, such as preoperative recipients' nutritional and skeletal muscle status, graft congestion, and donor factors, were also identified as risk factors which all have been addressed using various strategies. CONCLUSIONS The surgical approach controlling PV flow and pressure could help to prevent SFSS especially in severely ill recipients. In the absence of efficacious medications to resolve SFSS, conservative treatments, including aggressive fluid balance correction for massive ascites, anti-microbiological therapy to prevent or control sepsis and intensive nutritional therapy, are all required if SFSS could not be prevented.

Abstract
BACKGROUND To assess the appropriate energy expenditure requirement for liver transplant (LT) recipients in South Korea, 4 commonly used predictive equations were compared with indirect calorimetry (IC). METHODS A prospective observational study was conducted in the surgical intensive care unit (ICU) of an academic tertiary hospital between December 2017 and September 2018. The study population comprised LT recipients expected to remain in the ICU >48 hours postoperatively. Resting energy expenditure (REE) was measured 48 hours after ICU admission using open-circuit IC. Theoretical REE was estimated using 4 predictive equations (simple weight-based equation [25 kcal/kg/day], Harris-Benedict, Ireton-Jones [ventilated], and Penn State 1988). Derived and measured REE values were compared using an intraclass correlation coefficient (ICC) and Bland-Altman plots. RESULTS Of 50 patients screened, 46 were enrolled, were measured, and completed the study. The Penn State equation showed 65.0% agreement with IC (ICC, 0.65); the simple weight-based (25 kcal/kg/day), Harris-Benedict, and Ireton-Jones equations showed 62.0%, 56.0% and 39.0% agreement, respectively. Bland-Altman analysis showed that all 4 predictive equations had fixed bias, although the simple weight-based equation (25 kcal/kg/day) showed the least. CONCLUSION Although predicted REE calculated using the Penn State method agreed with the measured REE, all 4 equations showed fixed bias and appeared to be inaccurate for predicting REE in LT recipients. Precise measurement using IC may be necessary when treating LT recipients to avoid underestimating or overestimating their metabolic needs.

Abstract
Backgrounds/Aims Acute appendicitis is one of the most common emergent disease in the general population requiring surgical treatment. However, only a few cases of appendicitis after liver transplantation (LT) were reported. We described experiences of acute appendicitis after LT in single center. Methods From March 1988 to July 2019, we reviewed retrospectively all the patients who diagnosed with acute appendicitis after LT at the Seoul National University Hospital. We described and analyzed clinical outcomes of appendectomy after LT. Results A total of 12 patients out of 2,237 LT patients underwent appendectomy due to acute appendicitis. The mean age was 48±12 years. Nine patients (75%) underwent deceased donor liver transplantation (DDLT) and three patients (25%) underwent living donor liver transplantation (LDLT). The mean days from transplantation to the onset of acute appendicitis was 739 (range 57–4,496) days. Every patients underwent appropriate appendectomy within 1 days after visiting hospital. Leukocytosis was seen in three patients (25%). Seven patients (58%) underwent laparoscopic appendectomy and five patients (42%) underwent open appendectomy. The total operative time was 47.5 (range 25–135) minutes. The median postoperative hospitalization was 4 (range 2–11) days. There was no postoperative complications documented. There was no significant difference of clinical outcomes between laparoscopic appendectomy group and open appendectomy group. Conclusions Early surgical management achieved satisfactory postoperative results without graft dysfunction after LT. Laparoscopic appendectomy also could be applicable with safe and feasible outcomes even in post-LT recipients.

Abstract
Purpose Hepatorenal syndrome (HRS) is a fatal complication in patients with end-stage liver disease awaiting liver transplantation (LT). HRS often develops in patients with high model for end-stage liver disease (MELD) score. This study investigated the outcomes of peritransplant management of HRS in a high-volume LT center in Korea for 2 years. Methods A total of 157 recipients that deceased donor liver transplantation (DDLT) from January 2017 to December 2018 were included. In-hospital mortality (IHM) was analyzed in relation to pre- and posttransplant application of renal replacement therapy (RRT). Results Primary diagnoses for DDLT were alcoholic liver disease (n = 61), HBV-associated liver cirrhosis (n = 48), retransplantation for chronic graft failure (n = 24), and others (n = 24). Mean MELD score was 34.6 ± 6.2 with 72 patients at Korean Network for Organ Sharing MELD status 2 (45.9%), 43 at status 3 (27.4%), 36 at status 4 (22.9%), and 6 at status 5 (3.8%). Pretransplant RRT was performed in 16 patients (10.2%) that did not show IHM. Posttransplant RRT was performed in 69 patients (44.0%), for whom IHM incidence was 15.9%. In 53 patients that had undergone de novo posttransplant RRT, IHM incidence increased to 20.8%. IHM in the 88 patients not requiring RRT was 2.3%. Conclusion The majority of adult DDLT recipients in Korean MELD score-based allocation system have very high MELD scores, which is often associated with HRS. Pretransplant RRT appears to improve posttransplant survival outcomes. We thereby recommend that, if indicated, pretransplant RRT be performed while awaiting DDLT.

Liver diseases in the Asia-Pacific region: a Lancet Gastroenterology & Hepatology Commission. Lancet Gastroenterol Hepatol 2020; 5:167-228. [PMID: 31852635 PMCID: PMC7164809 DOI: 10.1016/s2468-1253(19)30342-5] [Citation(s) in RCA: 294] [Impact Index Per Article: 73.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2018] [Revised: 07/20/2019] [Accepted: 08/02/2019] [Indexed: 02/06/2023]
Abstract
The Asia-Pacific region is home to more than half of the global population and accounted for 62·6% of global deaths due to liver diseases in 2015. 54·3% of global deaths due to cirrhosis, 72·7% of global deaths due to hepatocellular carcinoma, and more than two-thirds of the global burden of acute viral hepatitis occurred in this region in 2015. Chronic hepatitis B virus (HBV) infection caused more than half of the deaths due to cirrhosis in the region, followed by alcohol consumption (20·8%), non-alcoholic fatty liver disease (NAFLD; 12·1%), and chronic infection with hepatitis C virus (HCV; 15·7%). In 2015, HBV accounted for about half the cases of hepatocellular carcinoma in the region. Preventive strategies for viral hepatitis-related liver disease include increasing access to clean drinking water and sanitation. HBV vaccination programmes for neonates have been implemented by all countries, although birth-dose coverage is extremely suboptimal in some. Availability of screening tests for blood and tissue, donor recall policies, and harm reduction strategies are in their initial stages in most countries. Many governments have put HBV and HCV drugs on their essential medicines lists and the availability of generic versions of these drugs has reduced costs. Efforts to eliminate viral hepatitis as a public health threat, together with the rapid increase in per-capita alcohol consumption in countries and the epidemic of obesity, are expected to change the spectrum of liver diseases in the Asia-Pacific region in the near future. The increasing burden of alcohol-related liver diseases can be contained through government policies to limit consumption and promote less harmful patterns of alcohol use, which are in place in some countries but need to be enforced more strictly. Steps are needed to control obesity and NAFLD, including policies to promote healthy lifestyles and regulate the food industry. Inadequate infrastructure and insufficient health-care personnel trained in liver diseases are issues that also need to be addressed in the Asia-Pacific region. The policy response of most governments to liver diseases has thus far been inadequate and poorly funded. There must be a renewed focus on prevention, early detection, timely referral, and research into the best means to introduce and improve health interventions to reduce the burden of liver diseases in the Asia-Pacific region.

Deceased donor liver transplantation under the Korean model for end-stage liver disease score-based liver allocation system: 2-year allocation results at a high-volume transplantation center. KOREAN JOURNAL OF TRANSPLANTATION 2019; 33:112-117. [PMID: 35769978 PMCID: PMC9188943 DOI: 10.4285/jkstn.2019.33.4.112] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Revised: 12/05/2019] [Accepted: 12/06/2019] [Indexed: 11/23/2022] Open
Abstract
Background The Korean model for end-stage liver disease (MELD) score-based liver allocation system was started in June 2016 in Korea. Methods This study analyzed the detailed allocation results of deceased donor liver transplantation (DDLT) during the first 2 years after the MELD score-based liver allocation system implementation at a high-volume liver transplantation (LT) center in Korea. Results This study included 174 patients with age above 12 years. The patient ABO blood groups were A (n=65, 37.4%), B (n=51, 29.3%), O (n=28, 16.1%), and AB (n=30, 17.2%). The LT types were primary LT in 141 patients (81.0%) and retransplantation in 33 (19.0%). The Korean Network for Organ Sharing status categories at LT were as follows: status 1 (n=11, 6.3%), status 2 (n=82, 47.1%), status 3 (n=63, 36.2%), and status 4 (n=18, 10.3%). The mean MELD score at LT and waiting period were 36.6±4.6 and 62.1±98.2 days in blood group A; 37.6±3.6 and 25.7±38.1 days in blood group B; 38.8±2.7 and 26.0±30.5 days in blood group O; and 34.8±5.5 and 68.4±110.5 days in blood group AB (P<0.001 and P=0.012), respectively. Patients with blood group O and AB had the highest and lowest mean MELD scores at LT allocation, respectively. Conclusions Serious deceased organ donor shortage resulted in very high MELD score cutoffs for DDLT allocation. Additionally, a significant inequality was observed in the possibility for DDLT according to blood group compatibility. Nationwide follow-up studies are necessary to precisely determine the allocation status of DDLT.

Abstract
BACKGROUND The relationship between institutional case volume and clinical outcomes after living donor liver transplantation is not clarified. METHODS We conducted a nationwide retrospective cohort study using the database of Korean National Healthcare Insurance Service. Between January 2007 and December 2016, 7073 adult living donor liver transplantations were performed at 50 centers in Korea. Centers were categorized according to the average annual number of liver transplantations: >50, 10 to 50, and <10. RESULTS In-hospital mortality rates in the high-, medium-, and low-volume centers were 2.8%, 4.1%, and 6.7%, respectively. After adjustment, in-hospital mortality was significantly higher in low-volume centers (adjusted odds ratio, 2.287; 95% confidence interval, 1.471-3.557; P < 0.001) and medium-volume centers (adjusted odds ratio, 1.676; 95% confidence interval, 1.089-2.578; P = 0.019) compared with high-volume centers. Long-term survival for up to 9 years was better, and intensive care unit and hospital length of stay were shorter in high-volume centers. CONCLUSIONS Centers with higher case volume (>50 liver transplantations/year) had better outcomes after living donor liver transplantation, including in-hospital mortality and long-term mortality compared with centers with lower case volume (≤50 liver transplantations/year).

Abstract
BACKGROUND & AIMS An optimal allocation system for scarce resources should simultaneously ensure maximal utility, but also equity. The most frequent principles for allocation policies in liver transplantation are therefore criteria that rely on pre-transplant survival (sickest first policy), post-transplant survival (utility), or on their combination (benefit). However, large differences exist between centers and countries for ethical and legislative reasons. The aim of this study was to report the current worldwide practice of liver graft allocation and discuss respective advantages and disadvantages. METHODS Countries around the world that perform 95 or more deceased donor liver transplantations per year were analyzed for donation and allocation policies, as well as recipient characteristics. RESULTS Most countries use the model for end-stage liver disease (MELD) score, or variations of it, for organ allocation, while some countries opt for center-based allocation systems based on their specific requirements, and some countries combine both a MELD and center-based approach. Both the MELD and center-specific allocation systems have inherent limitations. For example, most countries or allocation systems address the limitations of the MELD system by adding extra points to recipient's laboratory scores based on clinical information. It is also clear from this study that cancer, as an indication for liver transplantation, requires special attention. CONCLUSION The sickest first policy is the most reasonable basis for the allocation of liver grafts. While MELD is currently the standard for this model, many adjustments were implemented in most countries. A future globally applicable strategy should combine donor and recipient factors, predicting probability of death on the waiting list, post-transplant survival and morbidity, and perhaps costs. LAY SUMMARY An optimal allocation system for scarce resources should simultaneously ensure maximal utility, but also equity. While the model for end-stage liver disease is currently the standard for this model, many adjustments were implemented in most countries. A future globally applicable strategy should combine donor and recipient factors predicting probability of death on the waiting list, post-transplant survival and morbidity, and perhaps costs.

Abstract
Liver transplantation has been deemed the best choice for end-stage liver disease
patients but immune rejection after surgery is still a serious problem. Patients have to
take immunosuppressive drugs for a long time after liver transplantation, and this often
leads to many side effects. Mesenchymal stem cells (MSCs) gradually became of interest to
researchers because of their powerful immunomodulatory effects. In the past, a large
number of in vitro and in vivo studies have demonstrated the great potential of MSCs for
participation in posttransplant immunomodulation. In addition, MSCs also have properties
that may potentially benefit patients undergoing liver transplantation. This article aims
to provide an overview of the current understanding of the immunomodulation achieved by
the application of MSCs in liver transplantation, to discuss the problems that may be
encountered when using MSCs in clinical practice, and to describe some of the underlying
capabilities of MSCs in liver transplantation. Cell–cell contact, soluble molecules, and
exosomes have been suggested to be critical approaches to MSCs’ immunoregulation in vitro;
however, the exact mechanism, especially in vivo, is still unclear. In recent years, the
clinical safety of MSCs has been proven by a series of clinical trials. The obstacles to
the clinical application of MSCs are decreasing, but large sample clinical trials
involving MSCs are still needed to further study their clinical effects.

The 2016 ASE/EACVI recommendations may be able to more accurately identify patients at risk for diastolic dysfunction in living donor liver transplantation. PLoS One 2019; 14:e0215603. [PMID: 31013321 PMCID: PMC6478297 DOI: 10.1371/journal.pone.0215603] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Accepted: 04/05/2019] [Indexed: 12/20/2022] Open
Abstract
Background The aim of this study was to compare the prevalence of diastolic dysfunction between the 2016 American Society of Echocardiography (ASE)/European Association of Cardiovascular Imaging and 2009 ASE/European Association of Echocardiography recommendations in patients undergoing living-donor liver transplantation (LDLT). Patients and methods A total of 312 adult patients who underwent LDLT at our hospital from January 2010 to December 2017 were retrospectively analyzed. Exclusion criteria were systolic dysfunction, arrhythmia, myocardial ischemia, and mitral or aortic valvular insufficiency. Results The study population was largely male (68.3%), and the median age was 54 (49–59) years. The median model for end-stage liver disease score was 12 (6–22) points. A predominant difference in the prevalence rates of diastolic dysfunction was observed between the two recommendations. The prevalence rates of diastolic dysfunction and indeterminate diastolic function were lower according to the 2016 recommendations than the 2009 recommendations. The level of concordance between the two recommendations was poor. The proportion of patients with a high brain natriuretic peptide level (> 100 pg/mL) decreased significantly during surgery in the normal and indeterminate groups according to the 2009 recommendations; however, only the normal group showed an intraoperative decrease in the proportion according to the 2016 recommendations. Patients with diastolic dysfunction showed a poorer overall-survival rate than those with normal function according to both recommendations. However, there was a difference in the survival rate in the indeterminate group between the two recommendations. A significant difference in patient survival rate was observed between the dysfunction and indeterminate groups according to the 2009 recommendations; however, the difference was not significant in the 2016 recommendations. Conclusions The 2016 classification may be better able to identify patients with a risk for diastolic dysfunction. Particularly, patients in the 2016 indeterminate group seemed to require a cardiac diastolic functional evaluation more frequently during and after surgery than those in the 2009 indeterminate group.

Abstract
The concept of dual-graft liver transplantation was introduced to overcome the discrepancy between liver transplantation demand and liver donation. Dual-graft transplantation also mitigates cumulative family risk by decreasing individual donor risk through minimization of the resected liver volume from each donor. Here, we describe the first two cases performed in Saudi Arabia wherein a dual-graft living donor liver transplantation was facilitated by the use of one left lobe graft and one left lateral segment in both cases. These are the first two cases of dual-graft liver transplantation reported from Saudi Arabia and the Middle East. SIMILAR CASES PUBLISHED: Nine on the same subject in other parts of the world (Korea, Japan, Germany, China, and Brazil).

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
Liver disease accounts for approximately 2 million deaths per year worldwide, 1 million due to complications of cirrhosis and 1million due to viral hepatitis and hepatocellular carcinoma. Cirrhosis is currently the 11th most common cause of death globally and liver cancer is the 16th leading cause of death; combined, they account for 3.5% of all deaths worldwide. Cirrhosis is within the top 20 causes of disability-adjusted life years and years of life lost, accounting for 1.6% and 2.1% of the worldwide burden. About 2 billion people consume alcohol worldwide and upwards of 75 million are diagnosed with alcohol-use disorders and are at risk of alcohol-associated liver disease. Approximately 2 billion adults are obese or overweight and over 400 million have diabetes; both of which are risk factors for non-alcoholic fatty liver disease and hepatocellular carcinoma. The global prevalence of viral hepatitis remains high, while drug-induced liver injury continues to increase as a major cause of acute hepatitis. Liver transplantation is the second most common solid organ transplantation, yet less than 10% of global transplantation needs are met at current rates. Though these numbers are sobering, they highlight an important opportunity to improve public health given that most causes of liver diseases are preventable.

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
Although far advanced hepatocellular carcinoma (HCC) is generally considered a contraindication for liver transplantation (LT), biologically favorable tumors among them could show acceptable results. However, it is still unclear which tumors can be treated with LT. Data were collected on adult patients who underwent LT for HCC beyond the Milan criteria in 8 Korean LT centers between January 2000 and June 2013. Far advanced HCC was defined as HCC with the largest tumor ≥ 10 cm, 10 or more tumor nodules, or accompanying macrovascular invasion. A total of 688 patients, including 169 with far advanced HCC, were enrolled in this study. The 5-year overall and recurrence-free survival rates were 60.4% and 55.1%, respectively, for all patients but only 28.7% and 24.8%, respectively, for patients with far advanced HCC (P < 0.001). Both preoperative alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist II (PIVKA-II) were significant risk factors for HCC recurrence after LT. In particular, AFP + PIVKA-II combined was a better predictor than either marker alone. Of all far advanced HCC patients with available AFP and PIVKA-II levels, 45 (30.8%) had low AFP + PIVKA-II (≤300) and their 5-year overall and recurrence-free survival rate were 47.8% and 53.4%, respectively, which were acceptable and significantly superior to those of patients with AFP (ng/mL) + PIVKA-II (nAU/mL) > 300 (21.0% and 10.8%, respectively; P < 0.001). In conclusion, patients with favorable HCC had acceptable outcomes after LT even when their tumors were extremely advanced. AFP + PIVKA-II gave reliable information about the tumor biology of far advanced HCC. Liver Transplantation 00 000-000 2018 AASLD.

Single-Center Experience Using Marginal Liver Grafts in Korea. Transplant Proc 2018; 50:1147-1152.

Abstract
BACKGROUND Liver transplantation (LT) is an established therapeutic modality for patients with end-stage liver disease. The use of marginal donors has become more common worldwide due to the sharp increase in recipients, with a consequent shortage of suitable organs. We analyzed our single-center experience over the last 8 years in LT to evaluate the outcomes of using so-called "marginal donors." METHODS We retrospectively analyzed the database of all LTs performed at our institution from 2009 to 2017. Only patients undergoing deceased-donor LTs were analyzed. Marginal grafts were defined as livers from donors >60 years of age, livers from donors with serum sodium levels >155 mEq, graft steatosis >30%, livers with cold ischemia time ≥12 hours, livers from donors who were hepatitis B or C virus positive, livers recovered from donation after cardiac death, and livers split between 2 recipients. Patients receiving marginal grafts (marginal group) were compared with patients receiving standard grafts (standard group). RESULTS A total of 106 patients underwent deceased-donor LT. There were 55 patients in the standard group and 51 patients in the marginal group. There were no significant differences in terms of age, sex, Model for End-Stage Liver Disease score, underlying liver disease, presence of hepatocellular carcinoma, and hospital stay between the 2 groups. Although the incidence of acute cellular rejection, cytomegalovirus infection, and postoperative complications was similar between the 2 groups, the incidence of early allograft dysfunction was higher in the marginal group. With a median follow-up of 26 months, the 1-, 3-, and 5-year overall and graft (death-censored) survivals in the marginal group were 85.5%, 75%, and 69.2% and 85.9%, 83.6%, and 77.2%, respectively. Patient overall survival and graft survival (death-censored) were significantly lower in the marginal group (P = .023 and P = .048, respectively). On multivariate analysis, receiving a marginal graft (hazard ratio [HR], 4.862 [95% confidence interval (CI), 1.233-19.171]; P = .024) and occurrence of postoperative complications (HR, 4.547 [95% CI, 1.279-16.168]; P = .019) were significantly associated with worse patient overall survival. Also, when factors associated with marginal graft were analyzed separately, graft steatosis >30% was independently associated with survival (HR, 5.947 [95% CI, 1.481-23.886]; P = .012). CONCLUSIONS Patients receiving marginal grafts showed lower but acceptable overall survival and graft survival. However, because graft steatosis >30% was independently associated with worse survival, caution must be exercised when using this type of marginal graft by weighing the risk and benefits.

Abstract
Liver disease is a major cause of mortality worldwide. Liver transplantation (LT) is the most effective treatment for end stage liver disease. Available resources and social circumstances have led to different ways of implementing LT around the world. The experience with pediatric LT corroborates the hypothesis that a combination of surgical strategies can be beneficial. The goal of this manuscript is to describe the strategies used by LT centers in North America, Europe and Asia and how these strategies can be applied to reduce waitlist mortality and increase access to LT.

Demographic and Urbanization Disparities of Liver Transplantation in Taiwan. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15020177. [PMID: 29360736 PMCID: PMC5857045 DOI: 10.3390/ijerph15020177] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/13/2017] [Revised: 01/10/2018] [Accepted: 01/18/2018] [Indexed: 12/26/2022]
Abstract
Limited access to or receipt of liver transplantation (LT) may jeopardize survival of patients with end-stage liver diseases. Taiwan launched its National Health Insurance (NHI) program in 1995, which essentially removes financial barriers to health care. This study aims to investigate where there are still demographic and urbanization disparities of LT after 15 years of NHI program implementation. Data analyzed in this study were retrieved from Taiwan’s NHI inpatient claims. A total of 3020 people aged ≥18 years received LT between 2000 and 2013. We calculated crude and adjusted prevalence rate of LT according to secular year, age, sex, and urbanization. The multiple Poisson regression model was further employed to assess the independent effects of demographics and urbanization on prevalence of LT. The biennial number of people receiving LT substantially increased from 56 in 2000–2001 to 880 in 2012–2013, representing a prevalence rate of 1.63 and 18.58 per 106, respectively. Such increasing secular trend was independent of sex. The prevalence was consistently higher in men than in women. The prevalence also increased with age in people <65 years, but dropped sharply in the elderly (≥65 years) people. We noted a significant disparity of LT in areas with different levels of urbanization. Compared to urban areas, satellite (prevalence rate ratio (PRR), 0.63, 95% confidence interval (CI), 0.57–0.69) and rural (PRR, 0.76, 95% CI, 0.69–0.83) areas were both associated with a significantly lower prevalence of LT. There are still significant demographic and urbanization disparities in LT after 15 years of NHI program implementation. Given the predominance of living donor liver transplantation in Taiwan, further studies should be conducted to investigate factors associated with having a potential living donor for LT.

Abstract
Recurrence and metastasis are major challenges in the management of hepatocellular carcinoma (HCC) patients after resection. To identify a metastasis-associated gene signature, we performed comparative gene expression analysis with recurrent HCC tissues from HCC patients who underwent partial or total hepatectomy and from non-metastatic primary HCC tissues. From this, we were able to identify genes associated with HCC recurrence. TCIRG1 (T-Cell Immune Regulator 1) was one of the aberrantly overexpressed genes in patients with recurrent HCC who had undergone total hepatectomy. The significant overexpression of TCIRG1 was confirmed using the Liver Hepatocellular Carcinoma dataset from The Cancer Genome Atlas. High expression of TCIRG1 was significantly associated with poor 5-year disease-free and recurrence-free survival of HCC patients. TCIRG1 knockdown suppressed tumor cell growth and proliferation in HCC cell lines; caused a significant increase in the proportion of cells in the G1/S phase of cell cycle; induced cell death; suppressed the metastatic potential of HCC cells by selectively regulating the epithelial–mesenchymal transition (EMT) regulatory proteins E-cadherin, N-cadherin, Fibronectin, Snail and Slug; and significantly attenuated the metastatic potential of ras-transformed NIH-3T3 cells in vitro and in vivo. These findings suggest that TCIRG1 functions as a metastatic enhancer by modulating growth, death and EMT in HCC cells. TCIRG1 could be a therapeutic target for the treatment of liver malignancy and metastasis.

Abstract
Backgrounds/Aims Model for End-stage Liver Disease (MELD) score was adopted in June 2016 in Korea. Methods We analyzed changes in volumes and outcomes of deceased donor liver transplantation (DDLT) for 1 year before and after introduction of MELD scoring at Asan Medical Center. Results There were 64 cases of DDLT in 1 year before MELD introduction and 106 in 1 year after MELD introduction, an increase of 65%. The volume of DDLTs abruptly increased during first 3 months, but then returned to its usual level before MELD introduction, which indicated 3-month depletion of accumulated recipient pool with high MELD scores. The number of pediatric DDLT cases increased from 3 before MELD introduction to 11 after it, making up 21.4% and 47.8% of all cases of pediatric liver transplantation, respectively. The number of cases of retransplanted DDLTs increased from 4 to 27, representing 6.3% and 25.5% of all DDLT cases, respectively. The number of status 1 DDLT cases increased from 5 to 12, being 7.8% and 11.3% of all cases. Patient survival outcomes were similar before and after MELD introduction. Conclusions The number of DDLTs temporarily increased after adoption of MELD scoring due to accumulated recipient pool with high MELD scores. The numbers of retransplanted and pediatric DDLT cases significantly increased. Patient survival in adult and pediatric DDLT was comparable before and after adoption of MELD scoring. These results imply that Korean MELD score-based allocation system was successfully established within its first year.

Abstract
Abdominal solid-organ transplantation has revolutionized the life of children with end-stage organ failure. The international practice of transplant in the pediatric population is heterogeneous. Global trends in pediatric transplant activity are increasing, with diffusion of transplant activities into developing and emerging economies. The organization of deceased donor programs varies internationally (with strong association to a country's gross domestic product (GDP) per capita and health spending). While deceased donor programs are well established in advanced economies, emerging and developing countries rely heavily on living donor programs. There are efforts underway to increase availability of pediatric and neonatal donor organs. Prioritization of organs for children exists in different forms throughout the world. Pediatric transplantation as a subspecialty is young but growing around the world with a need to train surgeons and physicians in this discipline. Outreach efforts with multinational and multi-institutional partnerships have enabled resource poor countries to establish new transplant programs for children. Further international collaboration, good quality data collection and audit, prospective research and ongoing mentorship, and education are needed to further improve outcomes of all children receiving solid-organ transplants.

Abstract
Adult-to-adult living donor liver transplantation (A2ALDLT), outside of Asia, remains an important yet underutilized gift of life. For patients with end-stage liver disease, A2ALDLT is a proven transplantation option, with lower waiting list mortality and suffering, and equivalent or better allograft and patient survival than deceased-donor liver transplantation (DDLT). The risks to living donors and the benefit to their recipients have been carefully defined with long-term level 1 and 2 evidence-based study. An overview of the development and practice of living donor liver transplant (LDLT), including donor and recipient surgical allograft innovation, is provided. The issues of recipient selection, outcomes and morbidity, including disease-variable study and challenges past and present are presented in comparison with DDLT cohorts, and future insights are described. Central to practice is the careful and concise review of donor evaluation and selection and donor outcome, morbidity, quality of life and present and future strategies for donor advocacy and growth of the technique.

Abstract
Liver transplant (LT) is now an established indication for patients with chronic hepatitis B, mainly because of the development and use of hepatitis B immunoglobulin (HBIG) and oral antivirals for prophylaxis. The combination of low-dose HBIG and antivirals has been considered the standard prophylaxis regimen to prevent post-LT recurrence of hepatitis B. The important remaining issues are related to the long-term cost of HBIG and the risk of escape hepatitis B virus (HBV) mutants. Strategies for prevention of HBV after LT are constantly improving. With the availability of new nucleoside/nucleotide analogues, new post-LT strategies also should emerge.

Abstract
BACKGROUND Donor safety is the most important aspect in living-donor liver transplantation (LDLT). Gilbert syndrome is an autosomal recessive condition that is a common cause of isolated unconjugated hyperbilirubinemia, and its prevalence is not negligibly low in the general population. This study intended to assess donor safety and recipient liver function after LDLT with the use of right liver grafts from living donors with Gilbert syndrome. METHODS Among 2,140 right liver transplantations performed from January 2002 to December 20113 at our institution, we identified 12 living donors (0.6%) who showed a preoperative serum total bilirubin level of ≥2 mg/dL. These donors were clinically diagnosed with Gilbert syndrome. The clinical outcomes of these donors and their recipients were analyzed retrospectively. RESULTS The mean donor age was 24.6 ± 7.1 years, and 11 donors were male. All subjects met the preoperative evaluation conditions for right liver donation except for the level of unconjugated hyperbilirubinemia. The mean serum total bilirubin level of the donors was 2.23 ± 0.20 mg/dL before and 1.79 ± 0.61 mg/dL 1 year after right liver donation. The preoperative donor direct bilirubin level was 0.43 ± 0.19 mg/dL. The preoperative indocyanine green retention rate at 15 minutes was 8.2 ± 2.8%. All donors and recipients recovered uneventfully and were alive at the time of writing. The recipient serum total bilirubin level was 1.29 ± 0.47 mg/dL 1 year after LDLT. CONCLUSIONS We suggest that LDLT with living donors with Gilbert syndrome can be safely performed, but that a meticulous preoperative evaluation is vital to maximize donor safety.
