Abstract
BACKGROUND: Although left-lobe donation is considered safer, right-sided donor hepatectomy predominates in adult living donor liver transplantation (LDLT). We hypothesized that bilateral proficiency with donor hepatectomy reduces overall donor complications. METHODS: A retrospective review of 834 adult LDLT donors (221 left lobes) from January 2004 to December 2014 was performed, dividing cases into two eras based on left-graft experience. Donor complications within 6 months were investigated, focusing on graft side and surgical era. RESULTS: The overall complication rate was 17.6%, and was higher in right-lobe donors. In Era 2, during which left-lobe donation rates were three times higher, total complications decreased (14.7% vs. 20.9%, P=0.02). A significant reduction in postoperative ascites accounted for the lower overall complication rate. The proportion of major biliary complications (BCs) was halved from 62.5% to 25.0%. Right-lobe donor complications also decreased significantly (15.8% vs. 22.9%, P=0.032), demonstrating that it was not only increased left-lobe donations leading to lowered complication rates, but also greater experience with donor hepatectomy in general. CONCLUSIONS: Accumulating experience with bilateral donor hepatectomy leads to decreased donor morbidity and comparable outcomes for right and left lobes, further enhancing the goal of donor safety while balancing recipient needs. 2019 Hepatobiliary Surgery and Nutrition.
