Abstract
OBJECTIVE To compare minimally invasive (MILR) and open liver resections (OLRs) for hepatocellular carcinoma (HCC) in patients with metabolic syndrome (MS). BACKGROUND Liver resections for HCC on MS are associated with high perioperative morbidity and mortality. No data on the minimally invasive approach in this setting exist. MATERIAL AND METHODS A multicenter study involving 24 institutions was conducted. Propensity scores were calculated, and inverse probability weighting was used to weight comparisons. Short-term and long-term outcomes were investigated. RESULTS A total of 996 patients were included: 580 in OLR and 416 in MILR. After weighing, groups were well matched. Blood loss was similar between groups (OLR 275.9±3.1 vs MILR 226±4.0, P =0.146). There were no significant differences in 90-day morbidity (38.9% vs 31.9% OLRs and MILRs, P =0.08) and mortality (2.4% vs 2.2% OLRs and MILRs, P =0.84). MILRs were associated with lower rates of major complications (9.3% vs 15.3%, P =0.015), posthepatectomy liver failure (0.6% vs 4.3%, P =0.008), and bile leaks (2.2% vs 6.4%, P =0.003); ascites was significantly lower at postoperative day 1 (2.7% vs 8.1%, P =0.002) and day 3 (3.1% vs 11.4%, P <0.001); hospital stay was significantly shorter (5.8±1.9 vs 7.5±1.7, P <0.001). There was no significant difference in overall survival and disease-free survival. CONCLUSIONS MILR for HCC on MS is associated with equivalent perioperative and oncological outcomes to OLRs. Fewer major complications, posthepatectomy liver failures, ascites, and bile leaks can be obtained, with a shorter hospital stay. The combination of lower short-term severe morbidity and equivalent oncologic outcomes favor MILR for MS when feasible.

Abstract
OBJECTIVE Living donor liver transplantation (LDLT) using small grafts, especially left lobe grafts (H1234-MHV) (LLG), continues to be a challenge due to small-for-size syndrome (SFSS). We herein demonstrate that with surgical modifications, outcomes with small grafts can be improved. METHODS Between 2012 and 2020, we performed 130 adult LDLT using 61 (47%) LLG (H1234-MHV) in a single Enterprise. The median graft-to-recipient weight ratio was 0.84%, with graft-to-recipient weight ratio <0.7% accounting for 22%. Splenectomy was performed in 72 (56%) patients for inflow modulation before (n=50) or after (n=22) graft reperfusion. In LLG-LDLT, venous outflow was achieved using all three recipient hepatic veins. In right lobe graft (H5678) (RLG)-LDLT, the augmented graft right hepatic vein was anastomosed to the recipient's cava with a large cavotomy. Outcome measures include SFSS, early allograft dysfunction (EAD), and survival. RESULTS Graft survival rates at 1, 3, and 5 years were 94%, 90%, and 83%, respectively, with no differences between LLG (H1234-MHV) and RLG (H5678). Splenectomy significantly reduced portal flow without increasing the complication rate. Despite the aggressive use of small grafts, SFSS and EAD developed in only 1 (0.8%) and 18 (13.8%) patients, respectively. Multivariable logistic regression revealed model for end-stage liver disease score and LLG (H1234-MHV) as independent risk factors for EAD and splenectomy as a protective factor (odds ratio: 0.09; P =0.03). For LLG (H1234-MHV)-LDLT, patients who underwent prereperfusion splenectomy tended to have better 1-year graft survival than those receiving postreperfusion splenectomy. CONCLUSIONS LLG (H1234-MHV) are feasible in adult LDLT with excellent outcomes comparable to RLG (H5678). Venous outflow augmentation and splenectomy help lower the threshold of using small-for-size grafts without compromising graft survival.

Abstract
Abstract
Background
The feasibility and learning curve of laparoscopic living donor right hepatectomy was assessed.
Methods
Donors who underwent right hepatectomy performed by a single surgeon were reviewed. Comparisons between open and laparoscopy regarding operative outcomes, including number of bile duct openings in the graft, were performed using propensity score matching.
Results
From 2014 to 2018, 103 and 96 donors underwent laparoscopic and open living donor right hepatectomy respectively, of whom 64 donors from each group were matched. Mean(s.d.) duration of operation (252·2(41·9) versus 304·4(66·5) min; P < 0·001) and median duration of hospital stay (8 versus 10 days; P = 0·002) were shorter in the laparoscopy group. There was no difference in complication rates of donors (P = 0·298) or recipients (P = 0·394) between the two groups. Total time for laparoscopy decreased linearly (R2 = 0·407, β = –0·914, P = 0·001), with the decrease starting after approximately 50 procedures when cases were divided into four quartiles (2nd versus 3rd quartile, P = 0·001; 3rd versus 4th quartile, P = 0·023). Although grafts with bile duct openings were more abundant in the laparoscopy group (P = 0·022), no difference was found in the last two quartiles (P = 0·207).
Conclusion
Laparoscopic living donor right hepatectomy is feasible and an experience of approximately 50 cases may surpass the learning curve.

Abstract
BACKGROUND AND AIMS: This study was designed to analyze the feasibility of laparoscopic right posterior sectionectomy compared to laparoscopic right hemihepatectomy in patients with hepatocellular carcinoma located in the posterior segments. MATERIAL AND METHODS: The study included patients who underwent either laparoscopic right posterior sectionectomy or laparoscopic right hemihepatectomy for hepatocellular carcinoma located in segment 6 or 7 from January 2009 to December 2016 at Samsung Medical Center. After 1:1 propensity score matching, patient baseline characteristics and operative and postoperative outcomes were compared between the two groups. Disease-free survival and overall survival were compared using Kaplan-Meier log-rank test. RESULTS: Among 61 patients with laparoscopic right posterior sectionectomy and 37 patients with laparoscopic right hemihepatectomy, 30 patients from each group were analyzed after propensity score matching. After matching, baseline characteristics of the two groups were similar including tumor size (3.4 ± 1.2 cm in laparoscopic right posterior sectionectomy vs 3.7 ± 2.1 cm in laparoscopic right hemihepatectomy, P = 0.483); differences were significant before matching (3.1 ± 1.3 cm in laparoscopic right posterior sectionectomy vs 4.3 ± 2.7 cm in laparoscopic right hemihepatectomy, P = 0.035). No significant differences were observed in operative and postoperative data except for free margin size (1.04 ± 0.71 cm in laparoscopic right posterior sectionectomy vs 2.95 ± 1.75 cm in laparoscopic right hemihepatectomy, P < 0.001). Disease-free survival (5-year survival: 38.0% in laparoscopic right posterior sectionectomy vs 47.0% in laparoscopic right hemihepatectomy, P = 0.510) and overall survival (5-year survival: 92.7% in laparoscopic right posterior sectionectomy vs 89.6% in laparoscopic right hemihepatectomy, P = 0.593) did not differ between the groups based on Kaplan-Meier log-rank test. CONCLUSION: For hepatocellular carcinoma in the posterior segments, laparoscopic right posterior sectionectomy was feasible compared to laparoscopic right hemihepatectomy when performed by experienced laparoscopic surgeons.

Abstract
BACKGROUND East Asia is a known endemic area for hepatitis B, and living donor liver transplantation is mainly performed. Liver retransplantation (ReLT) is expected to become an increasing problem because of a shortage of organs. This study aimed to compare early and late ReLT with consideration of specific circumstances and disease background of East Asians. METHODS Between October 1996 and January 2015, 51 patients underwent ReLT; we performed a retrospective analysis of data obtained from medical records of the patients. Clinical characteristics, indication, causes of death, survival rate, and prognostic factors were investigated. RESULT The survival rate for early ReLT (n = 18) was 51.5% and that for late ReLT (n = 33) was 50.1% at 1 year postoperatively. Continuous venovenous hemodialysis and the use of mechanical ventilators were more frequent, and pre-retransplant intensive care unit stay and prothrombin time was longer in early ReLT than in late ReLT. Operation time was longer and the amount of intraoperative blood loss was greater in late ReLT than in early ReLT. Multivariate analysis showed that a higher C-reactive protein level increased mortality in early ReLT (P = .045), whereas a higher total bilirubin level increased the risk of death in late ReLT (P = .03). CONCLUSION Patients with early ReLT are likely to be sicker pre-retransplantation and require adequate treatment of the pretransplant infectious disease. On the other hand, late ReLT is likely to be technically more difficult and should be decided before the total bilirubin level increases substantially.

Abstract
BACKGROUND Living-donor liver transplantation (LDLT) has been accepted as feasible treatment for fulminant hepatic failure (FHF), although it has generated several debatable issues. In this study, we investigated the prognostic factors predicting fatal outcome after LDLT for FHF. METHODS From April 1999 to April 2011, 60 patients underwent LT for acute liver failure, including 42 patients for FHF at Samsung Medical Center, Seoul, Korea. Among 42 patients, 30 patients underwent LDLT for FHF, and the database of these patients was analyzed retrospectively to investigate the prognostic factors after LDLT for FHF. RESULTS Among 30 patients, 7 patients (23%) died during the in-hospital period within 6 months, and 23 patients (77%) survived until recently. In univariate analyses, donor age (>35 years), graft volume (GV)/standard liver volume (SLV) (<50%), cold ischemic time (>120 minutes), hepatic encephalopathy (grade IV), hepato-renal syndrome (HRS), and history of ventilator care were associated with fatal outcome after LDLT for FHF. In multivariate analyses, HRS, GV/SLV (<50%), and donor age (>35 years) were significantly associated with fatal outcome. Although the statistical significance was not shown in this analysis (P = .059), hepatic encephalopathy grade IV also appears to be a risk factor predicting fatal outcome. CONCLUSIONS The survival of patients with FHF undergoing LDLT was comparable to that in published data. In this study, HRS, GV/SLV <50%, and donor age >35 years are the independent poor prognostic factors.

Abstract
BACKGROUND ABO-incompatible (ABO-I) living donor liver transplantation (LDLT) has a high success rate. There are few detailed comparisons regarding biliary complications, infective complications and patient survival between ABO-compatible (ABO-C) and ABO-I LDLT. The aim was to compare the outcomes of ABO-I LDLT with those of ABO-C LDLT using the matched-pairs method. METHODS Patients who underwent ABO-I LDLT procedures between 2010 and 2013 were studied. They were matched for significant variables with patients who had ABO-C LDLT (1:2 matching). RESULTS Forty-seven ABO-I LDLT procedures were included. Ninety-four patients who had ABO-C LDLT were selected as a comparator group. The incidence of cytomegalovirus, bacterial and fungal infections during the first 3 months was similar after ABO-I LDLT and ABO-C LDLT (85 versus 76 per cent, 28 versus 37 per cent, and 13 versus 20 per cent, respectively). Antibody-mediated rejection occurred after two procedures within 2 weeks of transplantation, but liver function improved with plasma exchange in both patients. There were no differences in the rate of acute rejection and biliary complications between ABO-I and ABO-C groups (P = 0.478 and P = 0.511 respectively). Three patients who had ABO-I LDLT developed diffuse intrahepatic biliary complications and progressed to graft failure. The 1-, 2- and 3-year patient survival rates after ABO-I LDLT and ABO-C LDLT were 89 versus 87 per cent, 85 versus 83 per cent, and 85 versus 79 per cent, respectively. CONCLUSION The short-term outcomes of ABO-I LDLT were comparable to those of ABO-C LDLT in this study. ABO-I LDLT is an effective and safe transplant option with the potential to expand the pool of live donors.

Abstract
Liver transplantation (LT) is one of the few effective treatment options for hepatocellular carcinoma (HCC). Our aim in this study was to evaluate the risk factors for HCC recurrence and propose new criteria for LT based on pretransplantation findings. One hundred eighty patients who underwent LT for HCC between 2002 and 2008 were reviewed retrospectively. Outcome measures included maximal tumor size and number of tumors revealed by radiological studies before transplantation, demographics, and tumor recurrence. Maximal tumor size >6 cm, >7 tumors, and alpha-fetoprotein (AFP) levels >1000 ng/mL were identified as independent prognostic factors of HCC recurrence in univariate and multivariate analysis. Disease-free survival rate in patients with a maximal tumor size ≤6 cm, ≤7 tumors, and/or AFP levels ≤1000 ng/mL at 1, 3, and 5 years was 97.9%, 91.5%, and 90.0%, respectively, but the 1-, 3-, and 5-year disease-free survival rate of patients who had a maximal tumor size >6 cm, >7 tumors, and/or AFP levels >1000 ng/mL was 61.9%, 47.6%, and 47.6%, respectively (P < .001). In conclusion, LT can improve the survival of patients with advanced HCC if they have a maximal tumor size ≤6 cm, tumor number ≤7, and/or AFP levels ≤1000 ng/mL.

Abstract
In patients with hepatocellular carcinoma (HCC), the presence of bile duct tumor thrombi (BDTT) in the major bile ducts indicates poor prognosis compared with that of HCC patients without BDTT. However, the prognostic significance of incidental microscopic BDTT in the peripheral bile ducts after curative liver resection is not known. We compared the outcomes of HCC patients with and without microscopic BDTT in the peripheral bile ducts who underwent hepatectomy.The electronic medical records of 31 patients with microscopic BDTT (BDTT group) were retrospectively reviewed. To compare the surgical outcomes, 62 patients (No BDTT group) were randomly chosen from the remaining HCC patients without BDTT based on age, sex, etiology of HCC, tumor size, tumor number, and modified Union for International Cancer Control T staging.The 1-year, 2-year, and 3-year disease-free survival rates and overall survival rates were 54.8%, 34.0%, 34.0% and 90.1%, 69.2%, 61.0% in the BDTT group and 66.8%, 59.2%, 42.3% and 86.4%, 84.4%, 84.4% in the No BDTT group (P = 0.089 and P = 0.014, respectively). The overall survival curve in the No BDTT group was higher than that in the BDTT group. Multivariate analysis revealed that predisposing factors for tumor recurrence after curative liver resection included increased levels of the protein induced by vitamin K antagonist-II (PIVKA-II), tumor grades 3 and 4, and the presence of BDTT.This study demonstrates that HCC prognosis is worse in patients with incidental microscopic BDTT in the peripheral bile ducts than it is in those without BDTT. The presence of BDTT should therefore be considered when evaluating a patient's HCC prognosis after curative hepatectomy.

Abstract
PURPOSE Advanced donor age is a well-known risk factor for poor graft function after living donor liver transplantation (LDLT). In addition, advanced recipient age has a significant impact because of the high prevalence of comorbidities. We investigated the relationship between donor-recipient age gradient (DRAG) and the posttransplant outcomes in LDLT. METHODS We included 821 consecutive adult recipients who underwent LDLT from June 1997 to May 2011. According to the value of DRAG, they were divided into 2 groups: Negative years (the donor was younger than the recipient) and positive years (the donor was older than the recipient). These groups were further divided into subgroups (≤-21, -20 to -1, 0 to 20, and ≥21 years). We collected retrospectively patient characteristics, laboratory results, medical and surgical complications, and graft loss. RESULTS The positive DRAG group had higher level of posttransplant alkaline phosphatase, but a lower incidence of biliary complications. The negative DRAG group, particularly DRAG ≤ -21 years was associated with the superior 1-, 3-, 5-, and 10-year graft survivals. Recipients with DRAG ≥ 21 showed persistently inferior graft survival during the observation period. In cases of young donors, transplants utilizing lower DRAG seen between young donors and older recipients showed more favorable graft survival than that of young-to-young transplants. CONCLUSION This study demonstrated that DRAG and a fixed donor age limit could be significant factors to predict graft survival after LDLT. Patients should carefully consider the worse graft survival if the donor is older than the recipient by ≥20.

Abstract
OBJECTIVE The treatment of choice for combined hepatocellular and cholangiocarcinoma (cHCC-CC) is surgical resection. However, the efficacy of liver transplantation is not clear. We compared the surgical outcome of hepatic resection and liver transplantation for cHCC-CC. PATIENTS AND METHODS From 1995 to 2012, 89 patients were diagnosed with cHCC-CC after hepatic resection and 8 patients diagnosed with cHCC-CC after liver transplantation. We excluded 21 patients who were American Joint Committee on Cancer Staging Stage III or IV and lost to follow-up. The outcomes were reviewed retrospectively. RESULTS The poor prognostic factors in cHCC-CC patients who underwent hepatectomy were large tumor size (>5 cm), small safety margin (<2 cm), and low preoperative albumin level. The disease-free survival (DFS) and overall survival (OS) between the hepatectomy group (n = 68) and the liver transplant group (n = 8) was not statistically different (5-year DFS: 26.2% vs 37.5%, P = .333; 5-year OS: 42.1% vs 50%, P = .591). In the small tumor subgroup (tumor size <5 cm), the DFS and OS between the 2 surgical procedures was not different, and in the adequate resection margin subgroup (safety margin >2 cm), survival was comparable. CONCLUSIONS In well-selected cases with small tumor size and with preserved liver function, liver resection should be considered when complete resection is possible.

Abstract
BACKGROUND Acute-on-chronic liver failure (AoCLF) occurs in lymphoma patients because of hepatitis B virus (HBV) reactivation. We aimed to identify characteristics of patients who underwent liver transplantation (OLT) because of AoCLF that occurred due to HBV reactivation in the setting of lymphoma and to compare these patients with AoCLF patients who did not have lymphoma. METHODS Twenty patients underwent OLT due to AoCLF between February 2009 and June 2011. Among these patients, five were diagnosed with lymphoma before OLT and assigned to group 1. The remaining patients (n = 15) were assigned to group 2. RESULTS Hospitalization after transplantation in group 2 was longer than in group 1 (P = .014). However, there were no differences in other variables between the two groups. The overall survival rate of group 1 was lower than that of group 2, but there was no difference between the two groups (P = .134). With the exception of one patient, the median time from complete remission to liver transplantation in group 1 was 4.5 months (range, 1-15) in group 1. Lymphoma recurrence occurred in one patient 8 months after transplantation. CONCLUSION Our study revealed that OLT is a feasible and effective approach in AoCLF due to HBV reactivation in select lymphoma patients.

Abstract
Liver transplantation is the only effective treatment for end-stage liver disease. Because of the limited donor availability, attention has been focused on the possibility to restore liver mass and function through cell transplantation. Stem cells are a promising source for liver repopulation after cell transplantation, but whether or not the adult liver contains hepatic stem cells is highly controversial. Several studies have suggested the presence of stem cells in the adult normal human liver. However, a population with stem cell properties has not yet been isolated. The purpose of this study was to identify and characterize progenitor cells in normal adult human liver. We isolated and expanded human liver stem cells (HLSCs) from a donated liver not suitable for liver transplantation or characterizing them by fluorescence-activated cell sorter, polymerase chain reaction, and immunofluorescence assay. HLSCs expressed the mesenchymal stem cell markers CD29, CD73, CD44, CD90, CD105, and CD166 but not the hematopoietic stem cell markers CD34, CD45, and CD117. HLSCs were also positive for vimentin and nestin, a stem cell marker. The absence of staining for cytokeratin-19, CD117, and CD34 indicated that HLSCs were not oval stem cells. In addition, HLSCs expressed CD26, and in a small percentage of cells, cytokeratin-8 and cytokeratin-18, indicating a partial commitment to hepatic cells. We concluded that HLSCs expressed several mesenchymal but not hematopoietic stem cell markers as well as CD26 and CK18, indicating a partial commitment to hepatic cells.

Abstract
Various extracorporeal bioartificial liver (BAL) systems have been developed. To treat fulminant hepatic failure (FHF) patients. Direct cell-cell interaction is one of the major factors influencing the functions of cultured hepatocytes, which increase with progressing of cell aggregation in this study, we investigated the effects of plasma viability and function single and spheroid pig hepatocytes in vitro. Hepatocytes were cultured as spheroids by suspension culture in spinner flasks. We obtained pig plasma from animals in hepatic failure. Immobilized single pig hepatocytes exposed to the toxic pig plasma lost viability and liver function. However, immobilized pig hepatocyte spheroids showed stable ammonia removal functions and urea synthesis and lower lactate dehydrogenase, glutamine oxaloacetate transaminase, and glutamine pyruvate transminase levels during BAL operation. At 5 hours, the ammonia concentration in plasma decreased to 370 and 150 μg/dL by immobilized single and spheroid hepatocytes, respectively, the concentrations at which they were maintained thereafter. The urea concentrations in plasma were 44 versus 72 μg/dL in immobilized single versus spheroid hepatocytes respectively, at 5 hours of operation. Spheroid hepatocytes not only showed in vivo structure, but also maintained high levels of liver-specific functions. The spheroid-based BAL system may be a good candidate to treat FHF patients.

Abstract
BACKGROUND Many patients are diagnosed with hepatocellular carcinoma (HCC) within the Milan criteria. In Korea, these patients are preferentially treated with locoregional therapy (LRT) instead of living donor liver transplantation. We investigated the effectiveness of LRT in liver transplant recipients who met the Milan criteria at the time of HCC diagnosis and investigated risk factors for HCC recurrence. METHODS We retrospectively reviewed the medical records of patients diagnosed with HCC who met the Milan criteria between 2002 and 2008. RESULTS We performed 101 liver transplants for HCC during the study period. Seventy-one patients (70%) underwent pretransplant LRT. The disease-free survival rates at 1, 3, and 5 years in patients who received LRT were 96.6%, 93.1%, and 93.1%, and in those who did not receive LRT, 94.2%, 83.4%, and 83.4%, respectively. There were no differences between the 2 groups. Multivariate analysis showed that a low Model for End-Stage Liver Disease (MELD) score and microvascular invasion were independent predictors of HCC recurrence after transplantation. The MELD scores and rate of microvascular invasion were not statistically different in patients with or without previous LRT. CONCLUSION Pretransplant LRT for patients with HCC who met the Milan criteria at the time of diagnosis did not provide a clear benefit with respect to HCC recurrence after transplantation. If patients have suitable living donors, those who meet the Milan criteria should undergo a liver transplantation as soon as possible.

Abstract
OBJECTIVE Salvage liver transplantation (LT) has been proposed for patients with a small hepatocellular carcinoma (HCC) and preserved liver function. Few reports have been issued on salvage LT in a living-donor (LD) LT setting. Therefore, we performed this study to evaluate differences in tumor invasiveness and other risk factors on survival after salvage versus primary LDLT. METHODS Between September 1996 and December 2008, 324 patients with HCC underwent LT. We excluded 138 patient from the analysis, leaving 186 HCC patients for analysis, including 17 (9.1%) who had undergone earlier resection, the salvage LDLT cohort. The other 169 patients underwent primary LDLT. RESULTS Intrahepatic metastasis, Edmonson-Steiner histologic grade, microscopic vascular invasion, and preoperative serum alpha-fetoprotein levels significantly influenced tumor recurrence. Microscopic vascular invasion, intrahepatic metastasis, Edmonson-Steiner histologic grade, and treatment by salvage LDLT were significantly associated with poor patient survival univariate analysis. However, only microscopic vascular invasion was significant on multivariate analysis. The treatment modality (primary or salvage LDLT) was not observed to affect overall or disease-free survival significantly on multivariate analysis. Disease-free survival was significantly better in the primary than in the salvage LDLT group. Furthermore, patients in the primary LDLT group tended to show better survival. However, when stratified by the presence or absence of microscopic vascular invasion, no significant group difference was found for overall or disease-free survival among those without versus with microscopic vascular invasion. CONCLUSIONS Five-year overall survival after primary versus salvage LDLT were similar when differences in tumor pathologic features, such as microscopic vascular invasion, were taken into account. Multivariate analysis showed that the treatment itself was not a significant prognostic factor for survival.

Abstract
INTRODUCTION Anatomic variants of the hepatic vasculature are common, so precise preoperative donor evaluation, including variations in the vasculature, is essential. We analyzed the anatomic similarity according to the donor-recipient relationship. METHODS Among the cases who underwent living donor liver transplantations from September 2008 to January 2011 we selected 104 cases with clearly defined hepatic artery and portal vein on preoperative computed tomography. They were classified according to Hiatt et al for the hepatic artery and Cheng for the portal vein. We categorized the 104 cases into three groups: parents-child (n=40), sibling (n=24) and no-relation (n=40), for analysis of the concordance of the hepatic artery and portal vein. RESULT Anatomic variations were observed in 25% of donors and 23.1% of recipients in the hepatic artery and 6.7% of donors and 10.6% of recipients in the portal vein. There was no significant difference in the distribution of the type of hepatic vasculature. Identical anatomic variations between donors and recipients were observed in 62.5% of the parent-child; 66.7% of the sibling and 52.5% of no-related group (P=.493) in the hepatic artery and 92.5%, 100%, and 77.5% (P=.014) in the portal vein respectively. CONCLUSION There was no similarity in the anatomic variations of the hepatic artery according to the donor-recipient relationship, but a similarity in portal venous anatomy according to the donor-recipient relationship.

Abstract
PURPOSE Prostaglandin E1 (PGE1) has been used to improve hepatic blood flow and to reduce ischemia reperfusion injuries of allografts in liver transplantation. However, PGE1 undergoes extensive metabolic clearance in the pulmonary and splanchnic circulation during intravenous administration. We analyzed the effect of intraportally administered PGE1. METHODS Sixty living-donor liver transplant recipients received continuous infusions of PGE1 for 10 days immediately after the reperfusion of the allografts. Of them, 40 recipients received PGE1 intravenously (IV group) via the internal jugular vein, and 20 recipients received PGE1 intraportally (IP group) through a catheter in the inferior mesenteric vein. Data were collected for 3 weeks postoperatively. RESULTS The IP group exhibited lower initial aspartate aminotransferase and alanine aminotransferase levels compared with the IV group. However, no apparent differences were recognized in the serum albumin, total bilirubin, alkaline phosphatase, r-glutamyl transpeptidase, or prothrombin time levels between the 2 groups. Chylorous ascites were observed more frequently in the IP group. There was no difference in portal venous flow measured by Doppler sonogram between the 2 groups during the first postoperative week. CONCLUSION This study demonstrated that intraportal administration of PGE1 had a better cytoprotective effect against hepatocellular damage than intravenous administration, although it did not have additional benefits for perihepatic hemodynamics.

Abstract
BACKGROUND End-stage renal disease is associated with severe abnormalities in reproductive function. However, the abnormalities are reversed by successful kidney transplantation. The aim of the present study was to compare hormonal levels between recipients with successful kidney transplantations and healthy women with the same gynecologic conditions. METHODS The study group consisted of 31 women of reproductive age with end-stage renal disease who underwent successful kidney transplantation. The ratio of the control group, composed of healthy woman, to the study group was 3:1 matched for age and symptoms. RESULTS Abnormal bleeding (n = 14) and infertility were the most common gynecologic conditions in kidney transplant recipients. The levels of estrogen (E2) and follicle-stimulating hormone (FSH) in the study group were higher than in the control group, but the levels of progesterone (P4) and luteinizing hormone (LH) were lower in the study group than in the control group. There were no significant differences in prolactin and thyroid-stimulating hormone between the two groups. The incidence of infertility in patients who receive steroid was higher than those with no steroid use (P = .007). CONCLUSIONS Compared with healthy age- and symptom-matched women, female kidney transplant recipients have increased levels of E2 and FSH and decreased levels of P4 and LH. These differences in hormone profiles may predispose kidney transplant recipients to increased risk of gynecologic pathologies.

Abstract
OBJECTIVE The best antithymocyte globulin (ATG) preparation for induction suppression in kidney transplant recipients is still not clear. The aim of this study was to identify short- and long-term outcomes in kidney transplant recipients who received thymoglobulin or ATGAM as an induction agent. METHODS We retrospectively reviewed patients who underwent kidney transplantation from 1996 to 2010. Recipients were classified according to the ATG preparation. RESULTS One hundred fifty-two patients (64.4%) received thymoglobulin and 84 (35.6%) received ATGAM. The occurrence of delayed graft function in patients receiving thymoglobulin was higher than in patients receiving ATGAM (P = .005), but serum creatinine levels and acute rejection after kidney transplantation were not different between the two groups. The death-censored graft survival curve in thymoglobulin recipients was higher than in ATGAM recipients (P = .027). Bacterial infection was a predisposing factor for graft survival (P = .008). CONCLUSION The efficacy of thymoglobulin induction is generally better than that of ATGAM induction, and prevention of bacterial infections was just as important as the use of ATG because bacterial infection was an important risk factor for graft failure.

Abstract
Although several studies have addressed the engraftment of stem cells into the liver, the exact mechanisms in vivo remain unclear. In this study, we investigated the effects of soluble factors on cell migration using purified, expanded human liver stem cells (HLSCs) obtained from a pediatric liver resection. Using a in vitro transwell migration assay, we evaluated the migratory capacity of HLSCs under the influence of the cytokines tumor necross factor- [TNF]-α, interleukin [IL]-6, and interferon (IFN)-γ or the growth factors vascular endothelial growth factor [VEGF], basic fibroblast growth factor [bFGF], and hepatocyte growth factor [HGF], which are known to be highly secreted during liver injury. We also evaluated the migratory capacity indirectly influenced by cryopreserved human hepatocytes. The migration across the transwell membrane was promoted by VEGF, bFGF, TNF-α, IFN-γ, or hepatocytes. The cryopreserved human hepatocytes especially induced significant migration. These results suggested the presence of unidentified soluble factors from hepatocytes. This experiment described a reliable system for quantitative migration studies to broaden our understanding of the directional nature of cell migration.

Abstract
Organ donation after cardiac death (DCD) has been suggested due to the shortage of allografts in Korea. We investigated the outcomes of 446 deceased donor kidney transplant recipients in our center between September 1, 1995, and December 31, 2009. Twenty-four (5.4%) of those patients received DCD kidney grafts. The DCD group had a long intensive care unit stay, frequent inotropics use (such as norepinephrine and dopamine), low mean blood pressure and estimated glomerular filtration rate, and high serum creatinine and deceased donor scores compared to the standard criteria donor (SCD) group and the expanded criteria donor (ECD) group. Mean true warm ischemic time of the DCD group was 59.7 minutes based on asystole time. The DCD group had a long hospital stay after transplantation, but there was no statistically significant difference in delayed graft function and primary nonfunction. Serum creatinine levels at 3 months after transplantation in the ECD and DCD group were significantly higher than the SCD group (P < .001) but lower in the DCD group than in the ECD group at 6 months and 9 months (P < .001 and P = .004) posttransplantation. There were no statistically significant differences in serum creatinine levels or in the graft survival rates between groups at 12 months (P = .160 and P = .737). The use of DCD attracted Korean surgeons because DCD allografts are equivalent to a heart-beating donor. Donors who die during the evaluation of brain death should not be abandoned for procurement, and we need to try to harvest allografts after cardiac death (type 4 DCD) to expand donor pools.

Abstract
BACKGROUNDS Steroids are the predominant immunosuppressive agent used after liver transplantation even though patients may experience steroid-related side effects. AIMS The objective of this study was to determine whether steroid use influenced the outcomes of liver transplantations. METHODS Three hundred forty-four adult patients underwent liver transplantation between May 2002 and December 2007. We reviewed the medical records of these patients, excluding those younger than 18 years old or those who died within the first month. The protocol withdrawal group (group 1) ceased steroid use within 5 months after transplantation, while the late withdrawal group (group 2) continued steroid use beyond this 5-month posttransplantation period. RESULTS All patients were classified according to the onset of steroid withdrawal (group 1: n = 243; group 2: n = 99). The incidences of biopsy-confirmed and treated acute rejection episodes (ARE) at 12 and 24 months posttransplantation were 7.8% and 12.3% in group 1, but 25.3% and 27.3% in group 2, respectively (P = .001). The incidence of hepatitis B virus (HBV) recurrence in group 2 was higher than that in group 1 (P = .007). The HBV-free survival rates at 1 and 2 years posttransplantation were 99.0% and 97.1% in group 1 and 96.1% and 92.1% in group 2, respectively. New-onset diabetes, avascular necrosis of the femoral head, corticosteroid-resistant ARE, hepatocellular carcinoma recurrence, as well as graft and patient survivals did not differ between the two groups. CONCLUSIONS Acute rejection episodes and HBV recurrence occurred less frequently when steroids were discontinued within 5 months after liver transplantation.

Abstract
There is some controversy regarding the exact cytomegalovirus (CMV) antigenemia titer that should be used as a guideline for preemptive anti-CMV therapy. We performed 634 consecutive kidney transplantations between January 2000 and June 2007. Preemptive therapy employed intravenous gancyclovir treatment when the CMV antigenemia titer was >or=50/4x10(5) leukocytes after kidney transplantation. The 634 recipients were allocated into 2 groups according to the peak CMV antegenemia: group A, CMV antigenemia titer<50/4x10(5) (n=550); and group B, >or=50/40x10(5) (n=84). Among the 634 recipients, 264 were positive for CMV antigenemia, and 61 developed symptomatic CMV infections. The incidence of symptomatic CMV infections in group B was significantly higher than in group A. Two cases in both groups developed tissue-proven CMV disease: group A CMV colitis and CMV nephritis, and group B, 2 cases of CMV colitis. Graft and patient survival rates in groups A and B at 5 years posttransplantation were not different. The authors concluded that a CMV antigenemia titer of >or=50/4x10(5) leukocytes can be considered an appropriate guideline for preemptive anti-CMV therapy.

Abstract
Patients with unresectable, beyond Milan criteria, hepatocellular carcinoma (HCC) invariably undergo palliative transarterial chemoembolization (TACE). The aim of this study was to compare the outcomes of conventional TACE versus liver transplantation (LT) in unresectable (beyond Milan criteria) HCC. Twelve patients underwent LT and 86 TACE for unresectable, beyond Milan criteria HCC. The inclusion criteria were a single tumor<or=6.5 cm or <or=5 tumors and all tumors<or=5 cm based on initial radiologic findings. We excluded patients with double primary cancers, age>60 years, vascular invasion, or extrahepatic spread. Survival rates were calculated using the Kaplan-Meier method. Multivariate analysis showed that TACE was a prognostic factor for survival (hazard ratio, 16.66, P=.000). The LT group showed significantly better survival than the TACE cohort. Two cases (16.7%) in the LT group recurred at a median time of 13.5 months. Survival rates at 1, 3, and 5 years were 100%, 88.9%, and 76.2% in the LT group, and 85.6%, 45.6%, and 21.4% in the TACE group, respectively. Patients with unresectable, beyond Milan criteria HCC should be given the option to receive LDLT, because LT offers a significantly better likelihood of survival than TACE.

Abstract
Budd-Chiari syndrome (BCS), which is characterized by hepatic venous outflow obstruction due to occlusion of the major hepatic vein and/or the inferior vena cava (IVC), is rare. Traditionally, a caval resection is advocated for these patients; however, such a maneuver renders living donor liver transplantation (LDLT) impossible. We encountered BCS in 4/377 LDLT patients during a 5-year period (January 2003 to December 2007). This report examine the various surgical modifications in these 4 patients, who underwent to LDLT for BCS. Resection of right hepatic vein (RHV) with an adjacent fibrotic part of the IVC with direct anastomosis of the graft RHV to the IVC was performed in 2 patients. One patient underwent retrohepatic IVC excision and reconstruction with a cryopreserved autologous IVC graft. The fourth patient, with a preexisting mesoatrial shunt for BCS, underwent conversion of this to a RHV atrial shunt. Graft and patient survivals were 100%. There were few complications in either donors or recipients. LDLT for BCS can be performed safely with adequate venous drainage techniques and with anticoagulant therapy and good follow-up for early diagnosis and treatment of recurrence leading to excellent long-term results.

Abstract
Epstein-Barr virus (EBV) infections, associated with posttransplant lymphoproliferative disorder (PTLD) are known to develop in cytomegalovirus (CMV)-infected transplant recipients due to the indirect effects of CMV. This study evaluated risk factors for PTLD among pediatric liver transplant recipients with CMV infections. We reviewed the medical records of 119 patients<or=18 years old who underwent liver transplantation between September 1996 and April 2009. Sixty-six subjects (55.5%) displayed CMV antigenemia during the study period; 15 (12.6%) developed PTLD. Of these, 10 developed PTLD after CMV antigenemia. The other patients (n=5) were excluded due to negative CMV antigenemia. The incidence of PTLD influenced by CMV infection was not significantly different from the incidence of PTLD without underlying CMV (P=.258). There were no differences in age, gender, antiviral prophylaxis, type of liver transplantation, or acute rejection episodes in the incidence of between patients with versus without PTLD. EBV but not CMV high-risk groups were a predictor for the development of PTLD (P=.035). CMV syndrome, tissue-invasive CMV disease, and CMV peak titer were not associated with an increased risk of PTLD. The primary risk factor for PTLD was EBV high-risk patients (donor positive/recipient negative). CMV disease was not associated with PTLD in pediatric liver transplant recipients with CMV infections.

Abstract
We compared postoperative hepatic and renal functions between the two inhalational anesthetics, desflurane and sevoflurane in living donors undergoing right hepatectomy. Seventy-four adult donors were randomly allocated into Des group (n = 37) and sevo group (n = 37). Before the induction of anesthesia, morphine sulfate 400 microg was injected intrathecally. Anesthesia was maintained with one minimum alveolar concentration (MAC) of deflurane or sevoflurane plus continuous intravenous remifentanil. Liver and renal function tests were performed and analysed at preoperative period, immediately after operation, and on 1st, 2nd, 3rd, 5th, 7th, and 30th postoperative days (PODs). Aspartate aminotransferase (AST) showed significant elevations from the day of surgery to POD 3 and alanine aminotransferase (ALT) was significantly elevated on POD 1 and POD 3 in the sevo group. Albumin level was significantly lower on POD 2 in the sevo group. Creatinine was significantly higher on POD 3 and POD 30 and estimated glomerular filtration ratio was significantly lower on POD 3 and POD 30 in the sevo group. No patient developed hepatic or renal failures. The results of our study showed better postoperative hepatic and renal function test with desflurane than sevoflurane at equivalent dose of 1 MAC in living donors undergoing right hepatectomy, but further study is required to evaluate clinical importance.

Abstract
Living donor liver transplantation (LDLT) is a widely accepted treatment for end-stage liver diseases. Renal dysfunction, a frequent complication after liver transplantation, has an unfavorable effect on the prognosis. Despite special characteristics of LDLT, such as small-for-size graft syndrome (SFS), the relations between graft size and postoperative renal dysfunction have not been evaluated. So we described the relevance of previously known risk factors with SFS (graft-recipient body weight ratio [GRWR] < 0.8%) and early postoperative renal dysfunction in LDLT. The study population consisted of adults who received LDLT from May 1996 to November 2005. The 284 patients who were followed to 3 months after LDLT were classified as group I (n = 201, creatinine < 1.5 mg/dL) versus group II (n = 83, creatinine > or = 1.5 mg/dL). Univariate analysis showed renal dysfunction in the early postoperative period was related to preoperative total bilirubin, blood urea nitrogen, creatinine, prothrombin time level, model for end-stage liver disease (MELD) score, GRWR, presence of preoperative renal dysfunction, transfusion of packed red blood cell, fresh frozen plasma, cryoprecipitate, reoperation, and the need for renal replacement therapy (RRT). Upon multivariate analysis, MELD score, GRWR, preoperative renal dysfunction, and need for RRT were related to early postoperative renal dysfunction. In conclusion, there was a significant relationship between SFS (GRWR < 0.8) and early postoperative renal dysfunction.

Abstract
In a few cases of hepatocellular carcinoma (HCC), jaundice results from obstructive causes, including tumor invasion or thrombi in the bile duct. We have reported herein our experience with liver transplantation (OLT) for HCC cares showing bile duct thrombi (BDT). From September 1996 to August 2004, 140 adult patients underwent OLT for HCC at our center. Four patients (2.9%) who had OLT performed for HCC had BDT and were included in this study. The patients were all men of mean age 57.0 years. The initial total bilirubin levels were in the range of 2.0 to 30.5 mg/dL. The sizes of the tumors ranged from 2.0 cm to 3.0 cm in diameter, all were single lesions. The median follow-up period was 20.6 months (range: 17.6 to 28.1 months). The only case in which the BDT was identified intraoperatively died 20 months after OLT due to multiple intrahepatic recurrences. The other three patients were alive, showing no evidence of recurrence at the end of follow-up. Although a series of four is too small to reach any conclusion, we suggest that OLT may be a treatment option for HCC with BDT in selected cases.

Abstract
Steatotic liver graft transplantation affect donor safety as well as recipient survival. We investigated safety of donors according to the extent of fatty change. We retrospectively reviewed donors who underwent right hepatectomy from September 1999 to April 2005, dividing them into three groups according to degree of macrovesicular fatty change upon intraoperative liver biopsy. Group 1 included patients with macrovesicular steatosis of 0 approximately 9%: group 2, 10 approximately 19% and group 3, at least 20%. Two hundred forty-five donors were enrolled with a male to female ratio of 2.02:1 and mean age of 31.8 years. There were 163 donors in group 1, 75 in group 2, and seven in group 3. There was no statistically significant difference in body mass index, operative time, blood loss, postoperative peak serum bilirubin, and aspartate transaminase levels among groups 1, 2, and 3. Overall complication rate, including reoperation, biliary stricture, wound infection, ileus, transfusion, bile leak and fluid collection were not different between the groups. Postoperative hospital stay was also not different. Peak alanine transaminase level was different between each group, and prothrombin time between group 1 and 3, but days until return to normal levels in all measured laboratory parameters were not different. Residual liver volume percent was significantly smaller among group 1 compared to others. In conclusion, fatty livers with less than 30% macrovesicular steatosis may be good donor candidates without significant complications as long as sufficient residual liver volume is left for the donor.

Abstract
The model for end-stage liver disease (MELD) has been an excellent predictor of 3-month mortality among cirrhotic patients awaiting orthotopic liver transplantation (OLT). The aim of this study was to evaluate whether the preoperative MELD score predicts short-term prognosis after OLT. We enrolled 98 adult liver transplant patients performed at our center from January 2001 to December 2002. In univariate analysis of risk factors for death within 3 and 6 months after liver transplantation, serum total bilirubin, creatinine, MELD score, hyponatremia with ascites, Child-Turcotte-Pugh (CTP) score were statistically significant parameters (P < .05). By logistic regression, none of the risk factors were subjected to multivariate analysis showed statistical significance. The odds ratios of the MELD score, hyponatremia with ascites, CTP score within 3 months were 0.997, 1.151, and 0.726 with 95% confidence intervals of [0.899, 1.105], [0.102, 12.959], and [0.389, 1.352], respectively. The odds ratio of MELD score, hyponatremia with ascites, CTP score within 6 months were 0.996, 0.914, and 0.764, with 95% confidence intervals of [0.901, 1.102], [0.089, 9.369], and [0.417, 1.401], respectively. Although MELD score has been a good predictor of short-term prognosis before OLT, MELD did not show an influence on the short-term prognosis after liver transplantation in this study.

Abstract
Liver transplantation (OLT) is the treatment of choice for patients with hepatic cirrhosis related hepatocellular carcinoma (HCC). Among 156 liver transplant patients for HCC from June 1996 to February 2005, 23 had recurrent HCC. To evaluate risk factors that affect early recurrence of HCC after OLT, we divided the 23 patients into two groups: early (< or =12 months) and late (>12 months) recurrences. Among them, 15 patients were dead and eight alive patients had been followed to 31 July 2005. The most common recurrence site was the grafted liver (n = 15), next was bone (n = 11), lung (n = 8), lymph node (n = 6), brain (n = 4), skin (n = 2), adrenal gland (n = 1). There were no significant differences between the two groups in age or tumor size, number of tumors, cell differentiation, alpha-feto protein levels, tumor staging, number of patients within Milan criteria, steroid pulse therapy, infectious diseases, and immunostaining of tumor. In our study, there were no risk factors that predict early tumor recurrence. We noticed that more patients in the early recurrence group were excluded by Milan criteria due to a more progressed tumor staging with higher mean levels of serum alpha-feto protein.

Abstract
The introduction of high doses of hepatitis B immune globulin (HBIG) and lamivudine for liver transplantation (OLT) prophylaxis has reduced the risk of hepatitis B recurrence and improved the survival of patients transplanted for hepatitis B virus (HBV)-related liver disease. But, posttransplant prophylaxis strategies to treat the recurrence of HBV have not yet been standardized. We analyzed 23 patients with HBV recurrence among 340 HBV-associated liver transplants performed from September 1996 to April 2004 (6.7%). Nine patients underwent deceased donor OLT and 14, living donor OLT. Mean follow-up was 37 months. Seroconversion after recurrence was observed in 6 of 23 patients (26%). Mean time to HBV recurrence tended to be shorter among the seroconversion (+) patients compared to seroconversion (-) patients (10 months vs 19.7 months; P = .062). Seroconversion rate after HBIG and lamivudine combination therapy for patients with HBV recurrence was 37.5% and time to seroconversion after HBV recurrence was 1.7 months. Seroconversion was best achieved when the pretransplant HBV DNA level was high and HBeAg was positive. Also, seroconversion rate was increased when HBV DNA level was low and the alanine transferase level high at the time of recurrence and when the time to recurrence after transplantation was short. Seroconversion after HBV recurrence, which was observed in 26%, may be increased in selected cases. Accordingly, aggressive treatment should be undertaken after HBV recurrence.
