Abstract
BACKGROUND Living donor liver transplantation (LDLT) is an established treatment for advanced liver disease. Whether right lobe (RL) or left lobe (LL) LDLT provides the best outcomes for donors and recipients remains contentious. METHODS MedLine, Embase, PubMed, and Cochrane Central were searched to identify studies comparing RL- and LL-LDLT and reporting donor and/or recipient outcomes. Effect sizes were pooled using random-effect meta-analysis. Meta-regressions were used to explore heterogeneity. RESULTS Sixty-seven studies were included. RL donors were more likely to experience major complications (relative risk [RR] = 1.63; 95% confidence interval [CI] = 1.30-2.05; I2 = 19%) than LL donors; however, no difference was observed in the risk of any biliary complication (RR = 1.41; 95% CI = 0.91-2.20; I2 = 59%), bile leaks (RR = 1.56; 95% CI = 0.97-2.51; I2 = 52%), biliary strictures (RR = 0.99; 95% CI = 0.43-1.88; I2 = 27%), or postoperative death (RR = 0.51; 95% CI = 0.25-1.05; I2 = 0%). Among recipients, the incidence of major complications (RR = 0.85; 95% CI = 0.68-1.06; I2 = 21%), biliary complications (RR = 1.10; 95% CI = 0.91-1.33; I2 = 8%), and vascular complications (RR = 0.79; 95% CI = 0.44-1.43; I2 = 0%) was similar. Although the rate of small for size syndrome (RR = 0.47; 95% CI = 0.30-0.74; I2 = 0%) and postoperative deaths (RR = 0.62; 95% CI = 0.44-0.87; I2 = 0%) was lower among RL-LDLT recipients, no differences were observed in long-term graft (hazard ratio = 0.87; 95% CI = 0.55-1.38; I2 = 74%) and overall survival (hazard ratio = 0.86; 95% CI = 0.60-1.22; I2 = 44%). CONCLUSIONS LL donors experience fewer complications than RL donors, and LL-LDLT recipients had similar outcomes to RL-LDLT recipients. These findings suggest that LL-LDLT offers the best outcomes for living donors and similar outcomes for recipients when measures are taken to prevent small for size syndrome.

Abstract
The graft hepatic artery orifice is tiny in living donor liver transplantation, and therefore, it is more difficult to reconstruct the hepatic artery than in deceased donor liver transplantation. In situ, multi-vessel hepatic artery reconstruction in living donor liver transplantation is time-consuming, and reconstructions are often complicated if the hepatic graft has several stumps. We describe two living donor liver transplants using back-table microsurgical angioplasty to combine two hepatic artery stumps to create a single orifice, and sequential single-vessel hepatic artery reconstruction in the recipient. Briefly, we used double-needle interrupted sutures for the two hepatic artery stumps with a biangular stay-suture method in back-table microsurgical angioplasty. Each suture was placed from the inner side of the arterial wall to the outer side, which allowed for safe and reliable suturing. After placing the interrupted sutures in the anterior wall, we turned over the vessels in the cold storage on the back table and placed interrupted sutures in the posterior wall. In the recipient, the single stump of the graft was anastomosed to the recipient's hepatic artery using an interrupted pattern and a surgical microscope. The postoperative courses of the donors and recipients were uneventful. Back-table hepatic artery angioplasty is a feasible option to overcome the complexities of multi-vessel arterial reconstruction in living donor liver transplantation. We recommend performing secure multi-vessel hepatic arterial reconstruction adapted to the clinical scenario. Using simple appropriate anastomosis, back-table microsurgical angiography may provide good results in living donor liver transplantation.

Impact of middle hepatic artery reconstruction after living donor liver transplantation using the left lobe. Clin Transplant 2020; 34:e13850.

Abstract
INTRODUCTION The aim of this study was to clarify the impact of middle hepatic artery reconstruction on the outcomes of duct-to-duct biliary anastomosis after living donor liver transplantation (LDLT) using the left lobe. MATERIALS AND METHODS Among 258 patients who underwent LDLT using the left lobe, 216 patients who underwent hepatic artery reconstruction and one hepatic duct reconstruction with duct-to-duct interrupted anastomosis were divided into three groups: Group A (n = 123), one arterial stump with left hepatic artery reconstruction; Group B (n = 32), two arterial stumps with only left hepatic artery reconstruction; and Group C (n = 61), two arterial stumps with reconstruction of the left and middle hepatic arteries. The outcomes after LDLT were compared among the three groups. RESULTS No hepatic artery complications occurred. Group B had a significantly greater incidence of anastomotic biliary stricture than Group C. A multivariate analysis with Cox regression revealed that being in Group B was the only significant independent risk factor for postoperative anastomotic biliary stricture after LDLT. CONCLUSIONS Middle and left hepatic artery reconstruction is safe in LDLT and may prevent biliary stricture caused by dual hepatic artery reconstruction when the graft has left and middle hepatic artery stumps.

Abstract
Background Wisteria floribunda agglutinin positive human Mac-2 binding protein glycosylation isomer (M2BPGi) has recently developed as a noninvasive serum marker of liver fibrosis. Liver transplant candidates usually have high serum levels of M2BPGi due to advanced cirrhosis. The aim of the present study was to elucidate the kinetics of serum M2BPGi after liver transplantation and the relationships between the level of M2BPGi and graft function. Methods Fifteen recipients who underwent living donor liver transplantation (LDLT) between June 2015 and January 2016 and whose pretransplant, postoperative day (POD) 1, POD 3, and POD 7 sera were available for measuring M2BPGi were enrolled in this study. Small-for-size syndrome (SFSS) was defined as the presence of cholestasis (total bilirubin >10 mg/dL) on POD 7 and intractable ascites (>1 L/day on POD 14 or >500 ml/day on POD 28) without other specific causes. Results The median of pretransplant M2BPGi was 9.75 cutoff index (C.O.I.) (range, 3.04-24.49). There was neither any correlation between pretransplant M2BPGi and Model for End-Stage Liver Disease scores (r=0.416, P=0.123) nor Child-Turcotte-Pugh scores (r=-0.221, P=0.428). The levels of M2BPGi dramatically decreased after LDLT (median; 1.48 on POD 1, 1.47 on POD 3, 1.49 on POD 7). However, serum levels of M2BPGi rose again on POD 7 in some recipients and all 4 recipients with serum levels of M2BPGi exceeding 3.00 C.O.I. succumbed to SFSS later. When the cutoff of M2BPGi on POD 7 for predicting SFSS was determined to be 3.06 according to its receiver operating characteristic curve, both the sensitivity and the specificity for predicting later SFSS were 100%. Conclusions The levels of M2BPGi dramatically decreased after LDLT. A re-rise of M2BPGi predicted later development of SFSS.

Abstract
In living donor liver transplantation (LDLT), a left hepatic graft occasionally includes a replaced or accessory left hepatic artery (LHA). The procuring of such grafts requires extensive dissection along the lesser curvature of the stomach to elongate the replaced or accessory LHA on the donor side. On the recipient side, complicated arterial reconstruction is often necessary to use such grafts. We retrospectively reviewed the medical records of 206 adult recipients who underwent LDLT and their respective donors. The recipients and donors were divided into two groups according to the presence of the replaced or accessory LHA. Twenty-five grafts included a replaced or accessory LHA. Only one hepatic artery-related complication was observed in the current series, in which a pseudoaneurysm arose at the site of anastomosis between the donor accessory LHA and the recipient LHA. There was no increase in the incidence of postoperative complications in the donors with a replaced or accessory LHA in comparison with the donors without these arteries. The use of left hepatic grafts that included a replaced LHA or accessory LHA did not have any negative impact on the outcomes on either the donor or the recipient side.

Abstract
We conducted a retrospective investigation in order to clarify whether selecting the type of liver graft had an impact on outcomes of adult-to-adult living donor liver transplantation (AALDLT). Data from the medical records of the donors and the recipients of 321 consecutive cases of AALDLT performed between April 2004 and March 2014 were retrospectively analyzed. Our general criteria for selecting the type of liver graft was that a left graft was preferentially selected when the estimated volume of the left graft was ≥35% of the standard liver volume of the recipient, and that a right graft was selected only when the estimated remnant liver volume of the donor was ≥35% of the total liver volume. In this series, 177 left grafts, 136 right grafts, and 8 posterior grafts were used. The left grafts tended to have 2 or more arteries, whereas the right grafts tended to have 2 or more bile duct orifices. The graft survival curves and the incidences of severe complications were comparable between the AALDLT using right grafts and the AALDLT using left grafts. The preoperative estimation of graft size hardly enabled us to predict severe posttransplant complication. Moreover, small-for-size graft syndrome occurred regardless of the estimated graft volumes. Instead, donor age was a significant risk factor for small-for-size graft syndrome. In conclusion, left grafts should be more aggressively used for the sake of donors' safety. The use of hepatic grafts from older donors should be avoided if possible in order to circumvent troublesome posttransplant complications.
