Extended criteria donors (ECDs) have an impact on early allograft dysfunction (EAD), biliary complications, relapse of hepatitis C virus (HCV), and survivals. Early allograft dysfunction was frequently seen in grafts with moderate and severe steatosis. Donors after cardiac death (DCD) have been associated with higher rates of graft failure and biliary complications compared to donors after brain death. Extended warm ischemia, reperfusion injury and endothelial activation trigger a cascade, leading to microvascular thrombosis, resulting in biliary necrosis, cholangitis, and graft failure. The risk of HCV recurrence increased by donor age, and associated with using moderately and severely steatotic grafts. With the administration of protease inhibitors sustained virological response was achieved in majority of the patients. Donor risk index and EC donor scores (DS) are reported to be useful, to assess the outcome. The 1-year survival rates were 87% and 40% respectively, for donors with a DS of 0 and 3. Graft survival was excellent up to a DS of 2, however a DS >2 should be avoided in higher-risk recipients. The 1, 3 and 5-year survival of DCD recipients was comparable to optimal donors. However ECDs had minor survival means of 85%, 78.6%, and 72.3%. The graft survival of split liver transplantation (SLT) was comparable to that of whole liver orthotopic liver transplantation. SLT was not regarded as an ECD factor in the MELD era any more. Full-right-full-left split liver transplantation has a significant advantage to extend the high quality donor pool. Hypothermic oxygenated machine perfusion can be applied clinically in DCD liver grafts. Feasibility and safety were confirmed. Reperfusion injury was also rare in machine perfused DCD livers. I) IntroductionAs discussed earlier, extended criteria donors are used widely. In this chapter a review is given about the impact of ECD on the outcome. Living related liver transplantation is discussed shortly, whether the partial grafts can still be regarded as ECD or not. Machine perfusion, as a possible management was also reviewed briefly. Outcome parameters are divided as possible complications, and survival results. Complications are listed as early graft dysfunction, biliary complications, HCV recurrence. Survival rates are summarized separately. Split, and living related LT discussed briefly, and finally the machine perfusion, as a possible future aspect is summarized. Silberhummer et al figured out the recipients' condition by the delta-MELD: as the difference between the MELD at transplantation and the MELD at listing. Patients with a both delta-MELD>1 and an ECD>2 together had a higher chance to develop EAD, and also significantly higher risk for mortality [3]. Others report a similar incidence of EAD, PNF, acute rejection, biliary complication and also that ECD had no significant effect on either ICU stay or duration of postOLT ventilation, and also the postOLT laboratory test, bleeding, biliary and vascular complication rates were similar in ECD and non-...

We retrospectively analyzed the causes, risk factors, and impact of early relaparotomy after adult-to-adult living donor liver transplantation (LDLT) on the posttransplant outcome. Adult recipients who underwent initial LDLT at our institution between August 1997 and August 2015 (n = 196) were included. Any patients who required early retransplantation were excluded. Early relaparotomy was defined as surgical treatment within 30 days after LDLT. Relaparotomy was performed 66 times in 52 recipients (a maximum of 4 times in 1 patient). The reasons for relaparotomy comprised postoperative bleeding (39.4%), vascular complications (27.3%), suspicion of abdominal sepsis or bile leakage (25.8%), and others (7.6%). A multivariate analysis revealed that previous upper abdominal surgery and prolonged operative time were independent risk factors for early relaparotomy. The overall survival rate in the relaparotomy group was worse than that in the nonrelaparotomy group (6 months, 67.3% versus 90.1%, P < 0.001; 1 year, 67.3% versus 88.6%, P < 0.001; and 5 years, 62.6% versus 70.6%, P = 0.06). The outcome of patients who underwent 2 or more relaparotomies was worse compared with patients who underwent only 1 relaparotomy. In a subgroup analysis according to the cause of initial relaparotomy, the survival rate of the postoperative bleeding group was comparable with the nonrelaparotomy group (P = 0.96). On the other hand, the survival rate of the vascular complication group was significantly worse than that of the nonrelaparotomy group (P = 0.001). Previous upper abdominal surgery is a risk factor for early relaparotomy after LDLT. A favorable longterm outcome is expected in patients who undergo early relaparotomy due to postoperative bleeding.

The aim of this study was to analyze the outcomes of the most updated version and largest group of our standardized hybrid (laparoscopic mobilization and hepatectomy through midline incision) living donor (LD) hemihepatectomy compared with those from a conventional laparotomy in adult-to-adult living donor liver transplantation (LDLT). Of 237 adult-to-adult LDLTs from August 1997 to March 2017, 110 LDs underwent the hybrid procedure. Preoperative and operative factors were analyzed and compared with conventional laparotomy (n = 126). The median duration of laparoscopic usage was 26 minutes in the hybrid group. Although there was improvement in applying this procedure over time from the beginning of the series of cases studied, blood loss and operative duration were still smaller and shorter in the hybrid group. There was no significant difference between the groups in the incidence of postoperative complications greater than or equal to Clavien-Dindo class III. There was no difference in recipient outcome between the groups. Our standardized procedure of hybrid LD hepatectomy is applicable and safe for all types of LD hepatectomies, and it enables the benefit of both the laparoscopic and the open approach in a transplant center without a laparoscopic expert.

These results demonstrate basic profiles of atherosclerosis markers in young and elderly Japanese adults. Further study is needed to evaluate measures developed for application in early adulthood to prevent atherosclerosis.
