Living-donor liver transplantation has provided a solution to the severe lack of cadaveric grafts for the replacement of livers afflicted with end-stage cirrhosis, fulminant disease, or inborn errors of metabolism. The pioneering experience in Japan in the early 1990s helped open wide the avenues of a new branch of science that is technically demanding and whose benefits are clearly dramatic. The need for alternative sources of liver grafts was common to the entire Asian region and, fortunately, the option of obtaining partial liver grafts from live donors had already become tenable. By the second half of the past decade, living-donor liver transplant programs had been successfully established in Hong Kong, Taiwan, and Korea. More than 1,500 cases have been performed over a 12-year period. This report describes the cumulative experience in living-donor liver transplantation in Asia on the basis of data from five major liver transplant centers.

The aim of this study is to present our institutional experience in living donor liver transplantation (LDLT) as a treatment for end‐stage liver disease in children with biliary atresia (BA). A retrospective review of transplant records was performed. One hundred BA patients (52 males and 48 females) underwent LDLT. The mean follow‐up period was 85.5 months. The mean age was 2.4 years. The mean preoperative weight, height, and computed GFR were 12.2 kg, 82.5 cm, and 116.4 ml/min/1.73 m², respectively. Twenty‐seven patients were below 1 year of age, and 49 patients were below 10 kg at the time of transplantation. Ninety‐six had had previous Kasai operation prior to transplant. The mean recipient operative time was 628 min. The mean recipient intraoperative blood loss was 176 ml. Thirty‐five did not require blood or blood component transfusion. The left lateral segment (64) was the most common type of graft used. There were 27 operative complications which included 3 reoperations for postoperative bleeding, 9 portal vein, 4 hepatic vein, 4 hepatic artery, and 7 biliary complications. There was one in‐hospital mortality and one retransplantation. The overall rejection rate was 20%. The overall mortality rate was 3%. The 6‐month, 1‐year and 5‐year actual recipient survival rates were 99%, 98% and 98%, respectively.

Complications in a donor are a distressing but inevitable occurrence, since graft procurement is a major undertaking. Although the technique for procurement has some similarities to hepatic resection, a donor is very unlike a patient with malignancy. The risk factors identified in these patients cannot be extrapolated to donors. Donor hepatectomy carried out from June 1995 to March 2005 in Chang Gung Memorial Hospital, Kaohsiung Medical Center was reviewed with the aim of identifying risk factors for complications. There were 204 living donor liver transplants, with 205 donor hepatectomies, as 1 living donor liver transplantation was a dual graft. Ten donors (4.88%) suffered complications. There was no difference in terms of age, gender, body weight, operation, and parenchymal time between those who had complications and those who did not. There was also no difference in liver function tests between the 2 groups of donors, but the total bilirubin was significantly higher in donors with complications. The graft weight and remnant liver volume were also similar. The proportion of donors with fatty liver was the same between the 2 groups. The mean blood loss in donors with complications was 170 ± 79 mL, and that for donors without complications was 95 ± 77 mL. There was a statistically significant greater blood loss in donors with complications (P < 0.05). The number of segments removed in donors with complications was also higher compared to donors without complications (P < 0.03). Using multivariate analysis, intraoperative blood loss and the number of segments removed were found to be independent risk factors for donor complications. Intraoperative blood loss during graft procurement must be kept low to minimize complications in donors. Liver Transpl 12:950–957, 2006. © 2006 AASLD.

Background. Living donor liver transplantation (LDLT) demonstrates certain survival benefits over deceased donor liver transplantation for hepatocellular carcinoma (HCC) but there is no consensus on criteria for the use of LDLT for HCC for hepatocellular carcinoma (HCC) taking into account strategies to improve survival. Methods. Thirty-five patients (89% men) underwent LDLT for HCC. The mean age was 51 years (range, 22–61). The median disease severity scores were B, 11–20, and 2B for Child-Turcotte-Pugh, Model for End-stage Liver Disease, and United Network for Organ Sharing, respectively. The transplant records were retrospectively analyzed. Results. All were within Milan criteria at time of transplantation. A novel approach to downstaging tumors initially beyond the Milan criteria was evaluated using transarterial embolization or percutaneous ethanol injection. Our initial results were encouraging as recipients whose tumors had been downstaged had not had recurrence to date. Seven (20%) patients underwent hepatectomy for HCC before undergoing transplant. The overall mean posttransplant follow-up in this series was 40.3 months (range, 23–75). The overall posttransplant complication rate requiring intervention was 11%. There was only one malignancy recurrence for an overall recurrence rate of 3%. Vascular invasion and small- for-size transplants did not seem to influence tumor recurrence. The nonestimated recipient 1-year, 3-year, and 5-year survivals were 98%, 96%, and 90%, respectively. Conclusion. This review emphasizes the need for early disease recognition and prompt intervention when Milan criteria are met to improve survival from HCC after LDLT.
