Abstract
Difficulties of cadaveric donation and serious donor shortage have led to the development and popularization of living-related donor liver graft transplantation (LRLT). Because the history of this procedure is rather short, important aspects specific to this procedure have not been sufficiently documented. The objective of this study was to analyze a single center’s 10-year experience with 110 LRLT in pediatric and adult patients with end-stage liver diseases. The medical records of 110 consecutive patients who underwent LRLT were reviewed. The recipients were comprised of 72 children and 38 adults. The graft volume corresponded to 26–192% of the recipient’s standard liver volume. The relationship between pretransplant covariates and patient and graft survival was analyzed. Actuarial patient/graft survival rates were determined at 1, 3, and 5 years. The type and incidence of posttransplant complications were analyzed, as was long-term graft function. The 1-, 3-, and 5-year actuarial patient and graft survival rates were 88%, 85%, and 85%, respectively. Log-rank test demonstrated that ABO-compatibility predicted patient survival rate, whereas patient age, underlying disease, patient’s clinical status, donor-recipient relation, donor age, and graft volume/standard liver volume ratio did not. Long-term liver function remains excellent. All the donors have returned to normal daily lives with an uneventful course. LRLT is an efficacious procedure that provides excellent short-term and long-term survival. The indication criteria for both recipient and donor were legitimate in this series, except for transplant across ABO-incompatibility. Cautious expansion of this procedure may be justified under the situation of serious shortage of cadaveric donor.
