Abstract
Despite advancements in early diagnosis and medico-surgical treatment, hepatocellular carcinoma (HCC) is still a major cancer that causes substantial mortality in Asian countries. Liver transplantation (LT) has been accepted worldwide as the most effective treatment modality for patients with HCC; however, with the high incidence of HCC and low organ donation rate, Asia has developed distinctive features of indications and strategies for the application of LT. Unlike Western countries, living donor liver transplantation (LDLT) accounts for most LT cases for HCC in Asian countries, and most major transplantation centers perform LDLT for HCC patients with extended criteria. This article reviewed the current practice and outcome of LDLT for HCC from an Asian perspective and summarized the strategies that the high-volume LT centers in Asia use to obtain satisfactory oncologic results.

Abstract
OBJECTIVES Our goal was to investigate the correlation between indocyanine green test results and imaging parameters in living liver donor candidates. MATERIALS AND METHODS Our study included 219 healthy donor candidates who were evaluated with Doppler ultrasonography (portal vein time average flow), computed tomography (liver volume), liver biopsy (fat fraction), and indocyanine green retention rate at 15 minutes. RESULTS Portal vein time average flow (r= -0.375), fat-free liver volume/body weight ratio (r = -0.239), and portal vein time average flow × fat-free liver volume/body weight ratio (r = -0.424) showed significant correlations with indocyanine green retention rate at 15 minutes (all P < .001). CONCLUSIONS Imaging parameters were significantly correlated with indocyanine green retention rate at 15 minutes in living liver donor candidates.

Abstract
Simultaneous splenectomy (SSPX) in adult living donor liver transplantation (ALDLT) has definitely beneficial roles such as portal flow modulation in small-for-size graft and correction of hypersplenism-related pancytopenia, and so on, but disastrous complications after SSPX often occur. For the first time, we devised unique and innovative splenic devascularization (SDV) procedure to alleviated untoward effects of SSPX but to maintain its benefits for the indicated patients. From April 2013 to December 2014, 520 recipients underwent ALDLT, and the SSPX and SDV were simultaneously performed in 62 (11.9%) and 61 (11.7%) patients, respectively. The most common indication was hypersplenism-related pancytopenia (n = 101), small-for-size graft (n = 14), hepatitis C virus (HCV) (n = 7), and splenic artery aneurysm (n = 1). Postoperative small-for-size graft syndrome (SFSS) was absent in both SSPX and SDV, and preoperative pancytopenia was improved in both groups since postoperative 1 week, although SSPX was more substantial than SDV. Preoperative splenic volume (706.2 ± 282.9 ml) after SDV significantly decreased to 425.5 ± 204.4 ml on 1 month, respectively. In contrast to SDV, SSPX resulted in longer operation time and higher incidence of postoperative complications including mortality. In conclusion, SDV can replace SSPX during ALDLT without hampering its beneficial roles seriously, but get rid of splenectomy-related lethal complication.

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
BACKGROUND The outcomes of living donor liver transplantation (LDLT) versus deceased donor liver transplantation (DDLT) for HCC patients were not well defined and it was necessary to reassess. METHODS A comprehensive literature search was conducted in PubMed, Embase, Cochrane Library, Google Scholar and WanFang database for eligible studies. Perioperative and survival outcomes of HCC patients underwent LDLT were pooled and compared to those underwent DDLT. RESULTS Twenty-nine studies with 5376 HCC patients were included. For HCC patients underwent LDLT and DDLT, there were comparable rates of overall survival (OS) (1-year, RR = 1.04, 95%CI = 1.00-1.09, P = 0.03; 3-year, RR = 1.03, 95%CI = 0.96-1.11, P = 0.39; 5-year, RR = 1.04, 95%CI = 0.95-1.13, P = 0.43), disease free survival (DFS) (1-year, RR = 1.00, 95%CI = 0.95-1.05, P = 0.99; 3-year, RR = 1.00, 95%CI = 0.94-1.08, P = 0.89; 5-year, RR = 1.01, 95%CI = 0.93-1.09, P = 0.85), recurrence (1-year, RR = 1.41, 95%CI = 0.72-2.77, P = 0.32; 3-year, RR = 0.89, 95%CI = 0.57-1.39, P = 0.60; and 5-year, RR = 0.85, 95%CI = 0.56-1.31, P = 0.47), perioperative mortality within 3 months (RR = 0.89, 95%CI = 0.50-1.59, p = 0.70) and postoperative complication (RR = 0.99, 95%CI = 0.70-1.39, P = 0.94). LDLT was associated with better 5-year intention-to-treat patient survival (ITT-OS) than DDLT (RR = 1.11, 95% CI = 1.01-1.22, P = 0.04). CONCLUSION This meta-analysis suggested that LDLT was not inferior to DDLT in consideration of comparable perioperative and survival outcomes. However, in terms of 5-year ITT-OS, LDLT was a possibly better choice for HCC patients.

Abstract
Rationale: Adult-to-adult right lobe living donor liver transplantation is a viable alternative to whole liver transplantation from a deceased donor. The key aspect of the surgical procedure is the restoration of adequate graft blood flow and maintenance of sufficient volume of well vascularized parenchyma in the donor. Specific features of vascular anatomy in the donor and the recipient can be eventual cause for significant technical difficulties during transplantation. They can also increase the risk of complications and deteriorate graft functioning.Aim: To identify the incidence of various types of afferent and efferent vascularization of right lobe of the liver, potential techniques of vascular reconstructive procedures, rates and types of postoperative complications, as well as immediate surgical results.Materials and methods: We retrospectively analyzed the data on 220 right lobe liver transplantations adult patients, consecutively performed from 2010 to 2017 in one center. Specific characteristics of liver vascularization in donors and recipients were determined by pre-operative computed tomography and intra-operatively. The information on the types of vascular reconstruction, complications and results of surgical procedures was obtained from patients' medical files.Results: The following variants of blood supply to the right liver lobe were seen most frequently: portal vein trifurcation 22%, shortened trunk of the right portal vein branch 13%, supplementary v. hepatica from SgVIII with a diameter of > 5 mm 22%, supplementary lower right v. hepatica 17%, isolated venous outflow from all right lobe segments 2%, two arteries 2%. In addition, 17% of the recipients had portal vein thrombosis and 1% portal vein fibrosis. During the follow-up all donors remained alive. The rate of surgical complications was 12.5%, among them bile pocket or biloma 8.5%, intra-abdominal bleeding 2.5%, wound complications 1.5%. The rate of early post-operative complications in the recipients was 31.5%, with 4.5% of them being vascular and 15.5% biliary. The 6-months and 4-years survival of the recipients (Kaplan-Meier) was 98% and 95%, respectively.Conclusion: Immediate and longterm survival of the recipients of living donor right lobe live grafts, as well as absence of fatalities among their donors, confirm high effectiveness and expedience of this type of intervention. The observed anatomic variety of blood supply to the right liver lobe stipulates stringent requirements to the quality of preoperative diagnostics, deliberate donor selection, thorough planning of the procedure and high qualification of the surgical team. A relatively high rate of postoperative complications warrants the necessity of an intensive diagnostic monitoring in the early post-operative period and active strategies of their correction.

Abstract
BACKGROUND Early allograft dysfunction (EAD) defined by serum total bilirubin (TB) of 10 mg/dL or greater or prothrombin time-international normalized ratio (PT-INR) of 1.6 or greater on postoperative day 7 (POD 7) or aminotransferase greater than 2000 IU/L within the first week, is associated with early graft loss after deceased-donor liver transplantation. We aimed to determine the prognostic impact of the EAD definition in living-donor liver transplantation (LDLT). METHODS We analyzed the validity of the EAD definition and its impact on early graft survival in 260 adult recipients who underwent primary LDLT. RESULTS Eighty-four (32.3%) patients met the EAD criteria; 59 (22.7%) and 46 (17.7%) patients had TB of 10 mg/dL or greater and PT-INR of 1.6 or greater on POD 7, respectively, and 22 (8.5%) patients satisfied both criteria. Graft survival differed significantly when stratified according to TB of 10 mg/dL or greater and PT-INR of 1.6 or greater (P < 0.0001). PT-INR of 1.6 or greater resulted in higher graft mortality (risk ratio [RR], 3.87; P < 0.0001 at 90 days; RR, 2.97; P < 0.0001 at 180 days), as did TB of 10 mg/dL or greater (RR, 1.89; P = 0.027 at 90 days; RR, 1.91; P = 0.006 at 180 days). Coexistence of TB of 10 mg/dL or greater and PT-INR of 1.6 or greater was strongly associated with early graft loss (59.1%, RR, 6.97 at 90 days; 68.2%; RR, 5.75 at 180 days). In Cox regression analysis, PT-INR of 1.6 or greater and TB of 10 mg/dL or greater on POD 7 were significant risk factors for early graft loss (hazard ratio, 4.10; 95% confidence interval, 2.35-7.18; P < 0.0001, and hazard ratio, 2.43; 95% confidence interval, 1.39-4.24; P = 0.0018, respectively). CONCLUSIONS TB of 10 mg/dL or greater and/or PT-INR of 1.6 or greater on POD 7 predicted early graft loss after LDLT, and their coexistence worsened patient outcomes.

Abstract
BACKGROUND We assessed the prognostic impact of donor age on the outcome of adult living donor liver transplantation (LDLT). MATERIAL AND METHODS The study population comprised adult donor and recipients of right lobe grafts for LDLT performed from January 2005 to December 2016. There were 35 living donors aged ≥50 years (old-age donor group). As a control group, donors in their 20s (young-age donor group) were selected after one-to-one propensity score matching based on sex, model for end-stage liver disease (MELD) score, and primary diagnosis. RESULTS Donor age was 52.5±1.5 years versus 25.4±3.1 years in the old- and young-age donor groups, respectively. Remnant volumes of the 2 groups were 38.9±3.0% versus 38.1±2.9%, respectively (p=0.98). One-month regeneration rate of the remnant liver was 101.1±10.6% versus 104.5±11.8%, respectively (p=0.08), and there was no significant difference in the incidences of donor complications. Mean MELD score was 15 versus 14, respectively (p=0.82). Graft-to-recipient weight ratio was 1.02±0.43 versus 0.91±0.63, respectively (p=0.28). In the recipients, biliary complication occurred in 11.4% versus 8.6%, respectively (p=0.12), and there was no difference in 5-year survival rates of both groups (p=0.15). The 1-week and 1-month regeneration rates of the remnant left liver were 71.6±9.9% and 100.1±10.6% in the old-age group, respectively, whereas those were 80.2±12.1% and 104.5±11.8% in the young-age group, respectively (p=0.08). CONCLUSIONS Right lobe grafts from donors aged ≥50 years showed the usual recovery of graft function but rather delayed liver regeneration. Thus, old-aged donors should be selected prudently after consideration of hepatic resection rate, graft size, and hepatic steatosis.

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

Abstract
Background: Although many previous studies have confirmed that perioperative blood transfusion is associated with poor outcomes after liver transplantation (LT), few studies described the influence of single-donor platelet apheresis transfusion in living donor LT (LDLT). This study aimed to assess the effect of blood products on outcomes for LDLT recipients, focusing on apheresis platelets. Methods: This retrospective study included 126 recipients who underwent their first adult-to-adult LDLT. Twenty-four variables including consumption of blood products of 126 LDLT recipients were assessed for their link to short-term outcomes and overall survival. Kaplan-Meier survival curve and the log-rank test were used for recipient survival analysis. A multivariate Cox proportional-hazard model and a propensity score analysis were applied to adjust confounders after potential risk factors were identified by a univariate Cox analysis. Results: Patients who received apheresis platelet transfusion had a lower 90-day cumulative survival (78.9% vs. 94.2%, P = 0.009), but had no significant difference in overall survival in the Cox model, compared with those without apheresis platelet transfusion. Units of apheresis platelet transfusion (hazard ratio [HR] = 3.103, 95% confidence interval [CI]: 1.720–5.600, P < 0.001) and preoperative platelet count (HR = 0.170, 95% CI: 0.040–0.730, P = 0.017) impacted 90-day survival independently. Multivariate Cox regression analysis also found that units of red blood cell (RBC) transfusion (HR = 1.036, 95% CI: 1.006–1.067, P = 0.018), recipient's age (HR = 1.045, 95% CI: 1.005–1.086, P = 0.025), and ABO blood group comparison (HR = 2.990, 95% CI: 1.341–6.669, P = 0.007) were independent risk factors for overall survival after LDLT. Conclusions: This study suggested that apheresis platelets were only associated with early mortality but had no impact on overall survival in LDLT. Units of RBC, recipient's age, and ABO group comparison were independent predictors of long-term outcomes.

Abstract
INTRODUCTION Although the revised cardiac risk index (RCRI) is a useful tool for estimating the risk of postoperative cardiac events, whether it improves the prediction of cardiac events in patients undergoing liver transplantation (LT) has not been sufficiently demonstrated. METHODS We retrospectively analyzed 1429 patients who underwent LT. Cardiac events were defined as myocardial infarction, death, or combined events within 30 days after surgery. The RCRI was defined as the number of independent predictors including high-risk surgery, ischemic heart disease, congestive heart failure, cerebrovascular disease, insulin treatment, and creatinine level >2 mg/dL. Multivariate logistic regression analysis was performed to identify factors independently associated with cardiac events. The additive predictability of RCRI for the Model for End-Stage Liver Disease (MELD) score was assessed using receiver operating characteristic curve analysis. RESULTS Forty-four (3.1%) cardiac events occurred within 30 days after surgery. Both the MELD score (adjusted odds ratio [aOR], 1.05; P = .005) and RCRI (aOR, 4.35; P < .001 for RCRI score 2; aOR, 6.27; P = .009 for RCRI score 3 compared with RCRI score 1) independently predicted postoperative 30-day cardiac events. The model with MELD score plus RCRI was significantly more predictive for postoperative 30-day cardiac events than the model with MELD score alone (C-statistics 0.800 vs 0.757; P = .030). CONCLUSIONS For preoperative risk stratification, RCRI showed additive value to MELD score in predicting postoperative 30-day cardiac events after LT.

Abstract
Patency of the right hepatic vein (RHV) of the liver graft is essential for successful living-donor liver transplant (LDLT). We developed a simple technique for RHV reconstruction that does not require the use of cadaveric veins or additional time to prevent stenosis.Of 159 patients who underwent LDLT at our institution between May 2010 and April 2016, we included 152 in this study. Conventional RHV reconstruction was performed in 100 patients, while the diamond-shaped patch (D-patch) technique was performed in 53. For the D-patch technique, the posterior aspect of the RHV needs to be dissected from the liver parenchyma during donor hepatectomy, which prevents stenosis due to liver rotation after graft regeneration. A D-patch obtained from the hepatic vein of the recipient liver was used on the anterior aspect of the RHV for reconstruction. The Student's t test and χ test were used for statistical analysis.Rates of intervention for RHV stenosis during the first month were significantly different between the conventional reconstruction and D-patch groups (19.2% vs 3.8%; P = .01). The time taken to perform the D-patch technique was similar to that for conventional reconstruction (anhepatic period, 104.9 ± 47.3 minutes vs 106.7 ± 42.0 minutes; P = .82).The D-patch technique for RHV reconstruction in LDLT is a simple, fast, and feasible surgical technique that can be performed without using cadaveric or saphenous veins.

Abstract
BACKGROUND AND AIMS Acute liver failure (ALF) is a severe syndrome with an elevated mortality rate, ranging from 40 to 80 %. Currently, liver transplantation is the only definitive treatment for these patients and new therapies aiming to treat ALF include artificial organs implant and stem cells therapy, for example. However, a major limitation of liver donors exists. Living donor liver transplantation (LDLT), split liver transplantation (SLT), and domino liver transplantation (DLT) are some of the available alternatives to treat ALF patients, but these do not reduce the number of patients on waiting lists. Herein, we discuss domino hepatocyte transplantation (DHT) using livers that would not meet transplantation criteria. METHODS We conducted a literature search on PubMed/Medline using acute liver failure, liver transplantation, hepatocyte transplantation, and domino liver transplantation as key words. RESULTS New sources of biochemically functional hepatocytes and therapeutic treatments, in parallel to organ transplantation, may improve liver injury recovery and decrease mortality rates. Moreover, the literature reports hepatocyte transplantation as a therapeutic alternative for organ shortage. However, a major challenge remains for a wide clinical application of hepatocytes therapy, i.e., the availability of sufficient amounts of cells for transplantation. Ideally, hepatocytes isolated from livers rejected for transplantation may be a promising alternative for this problem. CONCLUSION Our review suggests that DHT may be an excellent strategy to increase cell supplies for hepatocyte transplantation.

Abstract
BACKGROUND Segment 5 (S5) sparing liver resection for cases that require an anatomic left trisectionectomy has not been reported yet. The authors intended to verify the outcome of S5-sparing extended left hepatectomy (ELH) in respect to venous outflow. METHODS All adult patients who underwent S5-sparing ELH between 2012 and 2017 in authors' institute have been enrolled in this study. S5-sparring ELH was defined as resection of S2, S3, S4, and S8 with or without S1. The surgery planning was based on the images from two-dimensional triphasic computed tomography and/or magnetic resonance imaging. A three-dimensional image reconstruction and liver volumetric study were performed retrospectively. RESULTS Out of 177 cases of major hepatic resection, only seven non-hilar cholangiocarcinoma patients underwent ELH during the study period. S5-sparing ELH was performed to five patients, in whom no tumor involvement in S5. The venous outflow of S5 has been maintained intraoperative, and S5 congestion has not been observed in all patients. Tailored management of the S5 venous outflow ensured an increase in functional remnant liver volume by 52.8% (range, 25.6 to 66.9%) by sparing of S5. A negative resection margin was achieved in all patients. One patient had postoperative bile leak requiring reoperation. No posthepatectomy liver failure (PHLF) has been observed. CONCLUSION S5-sparing ELH is technically feasible. Under the tailored management of S5 venous outflow, the functional future liver remnant can be increased. Further studies with larger sample size are needed to evaluate which circumstances the liver segment 5 could be preserved without venous reconstruction during the left extended hepatectomy.

Abstract
Liver transplantation (LT) is one of the most effective treatments for end-stage liver disease caused by related risk factors when liver resection is contraindicated. Additionally, despite the decrease in the prevalence of hepatitis B virus (HBV) over the past two decades, the absolute number of HBsAg-positive people has increased, leading to an increase in HBV-related liver cirrhosis and hepatocellular carcinoma. Consequently, a large demand exists for LT. While the wait time for patients on the donor list is, to some degree, shorter due to the development of living donor liver transplantation (LDLT), there is still a shortage of liver grafts. Furthermore, recipients often suffer from emergent conditions, such as liver dysfunction or even hepatic encephalopathy, which can lead to a limited choice in grafts. To expand the pool of available liver grafts, one option is the use of organs that were previously considered “unusable” by many, which are often labeled “marginal” organs. Many previous studies have reported on the possibilities of using marginal grafts in orthotopic LT; however, there is still a lack of discussion on this topic, especially regarding the feasibility of using marginal grafts in LDLT. Therefore, the present review aimed to summarize the feasibility of using marginal liver grafts for LDLT and discuss the possibility of expanding the application of these grafts.

Abstract
OBJECTIVE To investigate the value of Doppler ultrasound (US) in recipients of living donor liver transplantation (LDLT) using modified right-lobe grafts (mRLGs) with obstruction of the middle hepatic vein tributaries (MHVTs)-interposition vessel graft (IVG). METHODS This study included 240 consecutive LDLT recipients in whom 564 MHVTs (>5 mm) were reconstructed using IVG. Regular follow-up Doppler US was performed to assess the patency of the MHVTs-IVG and, if there was an obstruction, to evaluate for the establishment of collateral drainage. MHVTs with obstruction were subdivided into those with and without intrahepatic veno-venous collaterals on Doppler US and were correlated with CT scans. RESULTS MHVTs-IVG obstruction was identified in 137 patients with 227 MHVTs on follow-up Doppler US (6.2 ± 4.7 months). 90 patients with 149 MHVTs in whom the time interval between Doppler US and contrast-enhanced dynamic CT scans was <1 week were classified into either collateral (68 patients with 121 MHVTs) or non-collateral (22 patients with 28 MHVTs) groups. The presence of intrahepatic veno-venous collaterals on Doppler US were significantly related to no remarkable hepatic venous congestion on CT by both per-patient and per-vein analyses (66 of 68 patients (97.1%) and 118 of 121 MHVTs (97.5%), p < 0.001 and p < 0.001, respectively). CONCLUSION On Doppler US follow-up of LDLT recipients using mRLGs, identification of intrahepatic veno-venous collaterals associated with obstruction of MHVTs-IVG suggests no remarkable hepatic venous congestion. Advances in knowledge: When an obstruction of a MHVTs-IVG is encountered on Doppler US follow-up of LDLT recipients using mRLGs, no further evaluation with CT is warranted if intrahepatic veno-venous collaterals are observed on Doppler US, as this finding suggests no remarkable hepatic congestion.

Outcome of ABO-incompatible adult living-donor liver transplantation for patients with hepatocellular carcinoma. J Hepatol 2018; 68:1153-1162. [PMID: 29452208 DOI: 10.1016/j.jhep.2018.02.002] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2017] [Revised: 02/01/2018] [Accepted: 02/04/2018] [Indexed: 01/10/2023]
Abstract
BACKGROUND & AIMS Living-donor liver transplantation (LDLT) can simultaneously cure hepatocellular carcinoma (HCC) and underlying liver cirrhosis, improving long-term results in patients with HCC. ABO-incompatible LDLT could expand the living-donor pool, reduce waiting times for deceased-donor liver transplantation, and improve long-term survival for some patients with HCC. METHODS We retrospectively reviewed the medical records of patients undergoing LDLT for HCC from November 2008 to December 2015 at a single institution in Korea. In total, 165 patients underwent ABO-incompatible and 753 patients underwent ABO-compatible LDLT for HCC. ABO-incompatible recipients underwent desensitization to overcome the ABO blood group barrier, including pretransplant plasma exchange and rituximab administration (300-375 mg/m2 /body surface area). RESULTS We performed 1:1 propensity score matching and included 165 patients in each group. 82.4% of ABO-incompatible and 83.0% of -compatible LDLT groups had HCC within conventional Milan criteria, respectively, and 92.1% and 92.7% of patients in each group had a Child-Pugh score of A or B. ABO-incompatible and -compatible LDLT groups were followed up for 48.0 and 48.7 months, respectively, with both groups showing comparable recurrence-free survival rates (hazard ratio [HR] 1.14; 95% CI 0.68-1.90; p = 0.630) and overall patient-survival outcomes (HR 1.10; 95% CI 0.60-2.00; p = 0.763). CONCLUSIONS These findings suggested that ABO-incompatible liver transplantation is a feasible option for patients with HCC, especially for those with compensated cirrhosis with HCC within conventional Milan criteria. LAY SUMMARY Despite hypothetical immunological concerns that the desensitization protocol for breaking through the ABO blood group barrier might have a negative impact on the recurrence of hepatocellular carcinoma, our experience demonstrated no significant differences in the long-term overall survival and recurrence-free survival rates between patients receiving ABO-compatible or ABO-incompatible liver transplantation. In conclusion, results from our institution indicated that ABO-incompatible living-donor liver transplantation constitutes a potentially feasible option for patients with hepatocellular carcinoma, especially those with compensated cirrhosis with hepatocellular carcinoma within conventional Milan criteria.

Abstract
Living donor liver transplantation (LDLT) has found a place to serve the end-stage liver disease community as the donor safety and recipient suitability has been elucidated. Donor safety is of paramount importance and transplant programs must continue endeavors to maintain the highest possible standards. At the same time, adequacy of grafts based on recipient clinical status via their model for end-stage liver disease (MELD) score and volumetric studies to achieve a GRBWR >0.8, along with special attention to anatomic tailoring and portal venous flow optimization are necessary for successful transplantation. Technical innovations have improved sequentially the utility and availability of LDLT.

Abstract
Because of the shortfall between the number of patients listed for liver transplantation (LT) and the available grafts, strategies to expand the donor pool have been developed. Donation after circulatory death (DCD) and living donor (LD) grafts are not universally used because of the concerns of graft failure, biliary complications, and donor risks. In order to overcome the barriers for the implementation of using all 3 types of grafts, we compared outcomes after LT of DCD, LD, and donation after brain death (DBD) grafts. Patients who received a LD, DCD, or DBD liver graft at the University of Toronto were included. Between January 2009 through April 2017, 1054 patients received a LT at our center. Of these, 77 patients received a DCD graft (DCD group); 271 received a LD graft (LD group); and 706 received a DBD graft (DBD group). Overall biliary complications were higher in the LD group (11.8%) compared with the DCD group (5.2%) and the DBD group (4.8%; P < 0.001). The 1-, 3-, and 5-year graft survival rates were similar between the groups with 88.3%, 83.2%, and 69.2% in the DCD group versus 92.6%, 85.4%, and 84.7% in the LD group versus 90.2%, 84.2%, and 79.9% in the DBD group (P = 0.24). Furthermore, the 1-, 3-, and 5-year patient survival was comparable, with 92.2%, 85.4%, and 71.6% in the DCD group versus 95.2%, 88.8%, and 88.8% in the LD group versus 93.1%, 87.5%, and 83% in the DBD group (P = 0.14). Multivariate Cox regression analysis revealed that the type of graft did not impact graft survival. In conclusion, DCD, LD, and DBD grafts have similar longterm graft survival rates. Increasing the use of LD and DCD grafts may improve access to LT without affecting graft survival rates. Liver Transplantation 24 779-789 2018 AASLD.

Abstract
Desensitisation with therapeutic plasma exchange (TPE) is essential for ABO-incompatible (ABO-I) liver transplants (LTs). However, excessive citrate load and coagulation disturbances after TPE have been poorly studied, in particular in cirrhotic patients with hypocapnic alkalosis, metabolic compensation and electrolyte imbalances. We retrospectively evaluated 1123 consecutive LT recipients (923 ABO-compatible [ABO-C], 200 ABO-I) from November 2008 to May 2015. TPE was generally performed a day before LT and blood sampling was performed before anaesthesia induction. We performed propensity score matching (PSM) and inverse probability treatment weighting (IPTW) analyses. In 199 PSM pairs, metabolic alkalosis was prevalent in ABO-I LT recipients (expectedly due to citrate conversion) with higher pH ≥ 7.50 (IPTW-adjusted odds ratio [aOR] = 2.23) than in ABO-C LT recipients. With increasing cirrhosis severity, the arterial pH and bicarbonate levels showed dose-dependent relationships, whereas mild hypoxaemia was more prevalent in ABO-I LT recipients. ABO-I LT recipients exhibited worsened hypokalaemia ≤3.0 mmol/l (17.6%, aOR = 1.44), hypomagnesaemia ≤1.7 mg/dl (27.6%, aOR = 3.43) and thrombocytopenia <30,000/µl (19.1%, aOR = 2.26) confirmed by lower maximal clot firmness (P = 0.001) in rotational thromboelastometry (EXTEM), which necessitated platelet transfusions. Preoperative identification of these change may prevent worsening of severe electrolyte disturbances and thrombocytopenia for optimal LT anaesthesia.

Dual-graft adult living donor liver transplantation with ABO-incompatible graft: short-term and long-term outcomes. Am J Transplant 2018; 18:424-433.

Abstract
ABO-incompatible (ABOi) dual-graft (DG) adult living donor liver transplantation (ALDLT) is not commonly performed due to its inherently intricate surgical technique and immunological complexity. Therefore, data are lacking on the short- and long-term clinical outcomes of ABOi DG ALDLT. We performed a retrospective study by reviewing the medical records of patients who underwent ABOi DG ALDLT between 2008 and 2014. Additionally, computed tomography volumetric analysis was conducted to assess the graft regeneration rate. The mean age of a total of 28 recipients was 50.2 ± 8.5 years, and the mean model for end-stage liver disease score was 12.2 ± 4.6. The 1-, 3-, and 5-year patient survival rate was 96.4% during the mean follow-up period of 57.0 ± 22.4 months. The 1-, 3-, and 5-year graft survival rate was 96.4%, 94.2%, and 92.0%, respectively, and no significant differences were observed between ABO-compatible (ABOc) and ABOi grafts (P = .145). The biliary complication rate showed no significant difference (P = .195) between ABOc and ABOi grafts. Regeneration rates of ABOi grafts were not significantly different from those of ABOc grafts. DG ALDLT with ABOi and ABOc graft combination seems to be a feasible option for expanding the donor pool without additional donor risks.

Abstract
Living donor liver transplantation (LDLT) is a technically demanding endeavor, requiring command of the complex anatomy of partial liver grafts. We examined the influence of anatomic variation and reconstruction techniques on surgical outcomes and graft survival in the 9-center Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL). Data from 272 adult LDLT recipients (2011-2015) included details on anatomic characteristics and types of intraoperative biliary reconstruction. Associations were tested between reconstruction technique and complications, which included first biliary complication (BC; leak, stricture, or biloma) and first vascular complication (VC; hepatic artery thrombosis [HAT] or portal vein thrombosis [PVT]). Time to patient death, graft failure, and complications were estimated using Kaplan-Meier curves and tested with log-rank tests. Median posttransplant follow-up was 1.2 years. Associations were found between the type of biliary reconstruction and the incidence of VC (P = 0.03) and BC (P = 0.05). Recipients with Roux-en-Y hepaticojejunostomy had the highest probability of VC. Recipients with biliary reconstruction involving the use of high biliary radicals on the recipient duct had the highest likelihood of developing BC (56% by 1 year) compared with duct-to-duct (42% by 1 year). In conclusion, the varied surgical approaches in the A2ALL centers offer a novel opportunity to compare disparate LDLT approaches. The choice to use higher biliary radicals on the recipient duct for reconstruction was associated with more BC, possibly secondary to devascularization and ischemia. The use of Roux-en-Y biliary reconstruction was associated with VCs (HAT and PVT). These results can be used to guide biliary reconstruction decisions in the setting of anatomic variants and inform further improvements in LDLT reconstructions. Ultimately, this information may contribute to a lower incidence of technical complications after LDLT. Liver Transplantation 23 1519-1530 2017 AASLD.

Abstract
Purpose There is no consensus regarding the difference in outcomes of HCV in patients who receive living donor liver transplantation (LDLT) or compared to deceased donor liver transplantation (DDLT). The aims of this study were to compare characteristics between LDLT and DDLT groups and to identify risk factors affecting patient survival. Methods We retrospectively reviewed the multicenter records of 192 HCV RNA-positive patients who underwent liver transplantation. Results Thirty-five patients underwent DDLT, and 146 underwent LDLT. The 1-, 3-, and 5-year patient survival rates were 66.7%, 63.0%, and 63.0% in the DDLT group and 86.1%, 82.3%, and 79.5% in the LDLT group (P = 0.024), respectively. After propensity matching, the patient survival curve of the LDLT group was higher than that of the DDLT group. However, there was no statistically significant difference in patient survival between the 2 groups (P = 0.061). Recipient age ≥ 60 years, LDLT, and use of tacrolimus were positively associated with patient survival in multivariate analyses. Conclusion LDLT appears to be suitable for HCV-infected patients if appropriate living donor is available.

Abstract
Over the past two decades, the age of liver transplantation (LT) recipients has been increasing. We reviewed our experience with LT for patients aged ≥70 years (range: 70-78 years) and investigated the feasibility of performing LT, especially living donor LT (LDLT), for older patients. We retrospectively reviewed the medical records of 25 patients (15 LDLT recipients, 10 deceased donor LT recipients) aged ≥70 years who underwent LT from January 2000 to April 2016. Their perioperative morbidity rate was 28.0%, and the in-hospital mortality rate was 16.0%; these results were comparable to those of matched patients in their 60s (n = 73; morbidity, p = 0.726; mortality, p = 0.816). For patients in their 70s, the 1- and 5-year patient survival rates were 84.0% and 69.8%, and the 1- and 5-year graft survival rates were 83.5% and 75.1%, respectively. Comparisons of patient and graft survival rates between matched patients in their 60s and 70s showed no statistically significant differences (patient survival, p = 0.372; graft survival, p = 0.183). Our experience suggests that patients aged ≥70 years should not be excluded from LT, or even LDLT, based solely on age and implies that careful selection of recipients and donors as well as meticulous surgical technique are necessary for successful results.

Abstract
Liver transplantation has become the best way to cure patients with end-stage liver disease. Due to the shortage of donor organs worldwide and being unable to obtain matched donor liver, most patients with severe hepatic failure lose the chance of operation or even die. As a result, ABO incompatible (ABO-I) liver transplantation has become a choice to save the endangered life. However, compared with ABO compatible liver transplantation, ABO-I liver transplantation is more prone to cause severe antibody mediated rejection (AMR), biliary complications, infection, thrombotic microangiopathy, and acute kidney injury. Consequently, its clinical application is limited. In recent years, with the progress of AMR prevention strategies such as immunoabsorption, plasmapheresis, rituximab, splenectomy, intravenous immunoglobulin, and graft perfusion, the clinical efficacy of ABO-I liver transplantation has been significantly improved, although it still faces the challenge of how to prevent and control AMR and postoperative complications.

Abstract
BACKGROUND Only a limited number of centers have performed laparoscopic living donor hepatectomy to date. In particular, laparoscopic right hepatectomy is rarely performed because the procedure can only be performed by surgeons with significant experience in both laparoscopic liver surgery and liver transplantation with living donor liver grafts. METHODS Between November 2014 and February 2015, in a pure laparoscopic approach program for living right lobe donors at Asan Medical Center, 92 living donors underwent right hepatectomy for adult living donor liver transplantation. Among these, 3 pure laparoscopic living donor right hepatectomies were performed in 3 young female donors. RESULTS The intraoperative and postoperative courses for all 3 donors and recipients were uneventful without any complications. Laparoscopic living donor hepatectomy has definite advantages over conventional open surgery, including decreased wound morbidity and faster recovery. CONCLUSIONS According to the data of the present report, pure laparoscopic living donor right hepatectomy in properly selected living donors (only 4% of potential donors in this cohort) appears to be a safe and feasible procedure in adult living donor liver transplantation.

Abstract
Living donor liver transplantation (LDLT) has been increasingly embraced around the world as an important strategy to address the shortage of deceased donor livers. The aim of this guideline, approved by the International Liver Transplantation Society (ILTS), is to provide a collection of expert opinions, consensus, and best practices surrounding LDLT. Recommendations were developed from an analysis of the National Library of Medicine living donor transplantation indexed literature using the Grading of Recommendations Assessment, Development and Evaluation methodology. Writing was guided by the ILTS Policy on the Development and Use of Practice Guidelines (www.ilts.org). Intended for use by physicians, these recommendations support specific approaches to the diagnostic, therapeutic, and preventive aspects of care of living donor liver transplant recipients. Compared to cadaveric liver transplantation, live donor LT (LDLT) is challenged by ethical, medical and surgical considerations, many of which are still unresolved. The aim of this guideline is to provide a collection of expert opinions, consensus, and best practices surrounding LDLT.

Abstract
Background T lymphocytes are an essential component of allograft rejection and tolerance. The aim of the present study was to analyze and compare the characteristics of T cell subsets in patients who underwent deceased donor liver transplantation (DDLT) versus living donor liver transplantation (LDLT). Material/Methods Between April 2013 and June 2014, 64 patients underwent adult liver transplantation. The distribution of peripheral blood T lymphocyte subsets before transplantation and at 4, 8, 12, and 24 weeks post-transplantation were monitored serially. Results In the serial peripheral blood samples, the absolute CD3+ T cell counts in the LDLT group were higher than those in the DDLT group (p=0.037). The CD4+, CD8+, CD4/CD8, Vδ1, Vδ2, and γδ T cell counts did not change significantly over time in either group. The Vδ1/Vδ2 ratio was higher in patients with cytomegalovirus (CMV) infection than in patients without CMV infection (0.12 versus 0.26; p=0.033). The median absolute CD3+ and CD8+ T cell counts in patients with biopsy-proven acute rejection (BPAR) were 884 (range, 305–1,320) and 316 (range, 271–1,077), respectively, whereas they were 320 (range, 8–1,167) and 257 (range, 58–1,472) in patients without BPAR. The absolute CD3+ and CD8 T cell counts were higher in patients with BPAR than in patients without BPAR (p=0.007 and p=0.039, respectively). Conclusions With the exception of CD3+ T cells, T cell populations did not differ significantly between patients who received DDLT versus LDLT. In liver transplantation patients, CMV infection and BPAR were closely associated with T cell population changes.

Abstract
The large volume of adult living donor liver transplantations (ALDLTs) at our center affords a unique opportunity to examine the impact of acute-on-chronic liver failure (ACLF) among high-Model for End-Stage Liver Disease MELD score patients. From February 1998 to March 2010, 1958 cirrhotic recipients were analyzed to study the relationship between MELD scores and ALDLT outcomes. A total of 327 high-MELD score recipients were categorized into ACLF and non-ACLF groups, and their outcomes were compared. The 5-year graft and patient survival in the high-MELD group were 75.2% and 76.4%, respectively, which were significantly worse than the low and intermediate MELD groups. The presence of ACLF associated with higher MELD scores appeared to be the dominant factor responsible for the inferior results of patients with MELD score of 30-34 points. The 5-year graft survivals in the ACLF group was 70.5% and in the non-ACLF group it was 81.0% (p = 0.035). Therefore, ALDLT should be performed as soon as possible in high-MELD score patients prior to ACLF development. Moreover, ACLF patients should be separately categorized when analyzing the outcomes of ALDLT. ALDLT for ACLF patients should not be discouraged because favorable outcomes can be expected through timely ALDLT and comprehensive management.

Abstract
RATIONALE The shortage of available donor organs limits the development of liver transplantation. This case-serial study presents a novel way to expand the donor pool by using the other-wise discarded partial liver resection graft with hepatic benign tumor. PATIENT CONCERNS From 2012 to 2016, 15 patients with hepatic lesions were admitted to our hospital. 12 patients suffered from right epigastric discomfort and 3 patients worried about uncertain diagnosis. INTERVENTIONS Regular hepatic lobectomy was performed for all patients and after back-table management the resected partial liver grafts were used for patients with end-stage liver disease for liver transplantation. OUTCOMES All patients had improved liver function within 1 week of transplantation. Patients had no serious small-for-size syndrome despite graft-to-recipient weight ratio less than 0.8%. Back-table hepatic venous reconstruction with prosthetic vascular grafts was performed without serious early complications, and late thrombosis in vessel graft did not affect liver function. Postoperative computed tomography scans demonstrated a remarkable growth in graft volume and a continuous decrease in hemangioma in recipients using the grafts with hemangioma. One patient died from pulmonary embolism on day 7 after transplant, and the rest of 14 recipients had been surviving well, especially recipient 1 for more than 4 years, although 3 recipients had tumor recurrence and had been treated with sorafenib. DIAGNOSES The postoperative pathological diagnosis reported cavernous hemangioma (n = 11), perivascular epithelioid cell tumor (n = 2), inflammatory pseudotumor for (n = 1), and focal nodular hyperplasia (n = 1). LESSONS The partial liver grafts with hepatic benign tumors are safe for liver transplantation. In addition, prosthetic vascular grafts can be used for hepatic venous outflow reconstruction, especially in right lobe liver transplantation.

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
Auxiliary liver transplantation (ALT) for hepatitis B virus (HBV)-related liver cirrhosis previously showed poor results, because the native liver was a significant source of HBV recurrence and the graft could be rapidly destroyed by HBV infection in an immunosuppressive condition. Four patients with HBV-related liver cirrhosis were unable to undergo orthotopic liver transplantation because the only available grafts of left lobe were too small. Under entecavir-based anti-HBV treatment, they underwent ALT in which the recipient left liver was removed and the small left lobe graft was implanted in the corresponding space. The mean graft weight/recipient weight was 0.49% (range, 0.38%-0.55%). One year after transplantation, the graft sizes were increased to 273% and the remnant livers were decreased to 44%. Serum HBV DNA was persistently undetectable. Periodic graft biopsy showed no signs of tissue injury and negative immunostaining for hepatitis B surface antigen and hepatitis B core antigen. After a mean follow-up period of 21 months, all patients live well with normal graft function. Our study suggests that ALT for HBV-related liver cirrhosis is feasible under entecavir-based anti-HBV treatment. Successful application of small left livers in end-stage liver cirrhosis may significantly increase the pool of left liver grafts for adult patients.

Abstract
OBJECTIVE To measure and define the best achievable outcome after major hepatectomy. BACKGROUND No reference values are available on outcomes after major hepatectomies. Analysis in living liver donors, with safety as the highest priority, offers the opportunity to define outcome benchmarks as the best possible results. METHODS Outcome analyses of 5202 hemi-hepatectomies from living donors (LDs) from 12 high-volume centers worldwide were performed for a 10-year period. Endpoints, calculated at discharge, 3 and 6 months postoperatively, included postoperative morbidity measured by the Clavien-Dindo classification, the Comprehensive Complication Index (CCI), and liver failure according to different definitions. Benchmark values were defined as the 75th percentile of median morbidity values to represent the best achievable results at 3 month postoperatively. RESULTS Patients were young (34 ± [9] years), predominantly male (65%) and healthy. Surgery lasted 7 ± [2] hours; 2% needed blood transfusions. Mean hospital stay was 11.7± [5] days. 12% of patients developed at least 1 complication, of which 3.8% were major events (≥grade III, including 1 death), mostly related to biliary/bleeding events, and were twice higher after right hepatectomy. The incidence of postoperative liver failure was low. Within 3-month follow-up, benchmark values for overall complication were ≤31 %, for minor/major complications ≤23% and ≤9%, respectively, and a CCI ≤33 in LDs with complications. Centers having performed ≥100 hepatectomies had significantly lower rates for overall (10.2% vs 35.9%, P < 0.001) and major (3% vs 12.1%, P < 0.001) complications and overall CCI (2.1 vs 8.5, P < 0.001). CONCLUSIONS The thorough outcome analysis of healthy LDs may serve as a reference for evaluating surgical performance in patients undergoing major liver resection across centers and different patient populations. Further benchmark studies are needed to develop risk-adjusted comparisons of surgical outcomes.

Abstract
Even though auxiliary partial orthotopic liver transplantation (APOLT) as a technique was popularized in the late 80s, its role in metabolic liver disease remains controversial. The slow progress in gene therapy research, high incidence of technical complications, and the problem of long term graft atrophy have been roadblocks to its wider application. Better understanding of reciprocal dynamics of portal flow and regeneration between the graft and native liver along with multiple refinements in surgical technique have improved the outcomes of this operation, making it a safe alternative to orthotopic liver transplantation for patients with a wide range of noncirrhotic metabolic liver diseases (NCMLD). The ability to perform APOLT safely has also opened up a range of exciting indications in the setting of NCMLD. This article reviews the current status of APOLT for NCMLD, technical refinements which have improved outcomes and novel indications, which have rekindled fresh interest in this procedure.

Abstract
Background The decision to become a living liver donor is a stressful event. Ambivalence in decision making may result in psychological distress. Thus, the purpose of this study was to provide a description of the ambivalence of potential living liver donors, to examine the predictors of ambivalence, and to compare the ambivalence of potential living liver donors with that of actual living liver donors. Methods This descriptive and correlational study was conducted in a medical center from August 2013 to December 2015. Self-reported questionnaires were used to collect data. A total of 263 potential living liver donors who were assessed for donation to their parents were included in this study. Results The mean age of the total sample was 30.7 years (SD = 6.39, range = 20–47), and males comprised 53.6% of the sample. The majority of the potential donors had a college education (70.8%) and were single (63.5%). Of the total sample, the mean score for ambivalence was 4.27 (SD = 1.87, range = 0–7). Multivariate analysis revealed that the Mental Component Summary (MCS) of quality of life (β = -0.24, p < 0.01), family support (β = -0.17, p = 0.007), and intimacy (β = -0.13, p = 0.04) were significant protective predictors of ambivalence. Actual living liver donors had significantly lower ambivalence (3.82 versus 4.60), higher intimacy with recipients (3.55 versus 3.34), higher MCS (45.26 versus 42.80), and higher family support (34.39 versus 29.79) than did the remaining potential living liver donors. Conclusion Ambivalence is common in potential living liver donors. The MCS of quality of life, family support, and intimacy were protective predictors in terms of ambivalence. Future research should explore other factors and design interventions targeted toward reducing ambivalence, promoting family support, and enhancing the mental dimensions of quality of life in potential living liver donors.

Abstract
BACKGROUND Preoperative donor liver biopsy is the criterion standard to verify the quality of a liver. However, it can cause some complications, thus this study was designed to know whether selective liver biopsy is possible or not, and to find a subgroup that does not require preoperative biopsy. METHODS We reviewed preoperative images and postoperative outcome in 118 donors from September 2013 to January 2014. Visual grading of steatosis on plain computed tomography (CT) was performed and compared steatosis on preoperative liver biopsy was done within 7 days from the CT scan. RESULTS Visual grades of plain CT were 1 (n = 50, 42.4%), 2 (n = 47, 39.8%), 3 (n = 13, 11.0%), 4 (n = 7, 5.9%), and 1 (n = 1, 0.8%). Macrovesicular steatosis on liver biopsy according to visual grades were 1 (0.67 ± 1.3%), 2 (1.67 ± 1.8%), 3 (6.23 ± 6.4%), 4 (14.7 ± 16.6), and 5 (30%). Right liver grafts including right lobe, modified right lobe, and extended right lobe were procured in 106 (89.9%) donors, and 16% (17/106) of the donors were visual grades 3, 4, and 5. Eleven donors (64.7%) were accepted for right liver donation after liver biopsy, whereas 6 (35.3%) donors were deemed possible to donate right liver after weight reduction and reevaluation of steatosis. Transient hepatic dysfunction after right hepatectomy was significantly increased according to the increment of visual grade. CONCLUSIONS Preoperative liver biopsy may not be necessary in visual grade 1 or 2 donors, but should be performed for grade 3 and 4 donors based on recipient's urgency so as to decide whether to proceed with right hepatectomy or not.
