Background and Objectives : Living donor liver transplantation (LDLT) has been expanding to adult recipients by using right lobe grafts. However, the incidence of complications is more frequent than that involving left lobe grafts. Hence, we aimed to analyze postoperative complications in right lobe liver donors as a step to improve the results in the donors. Methods : Three hundred and eleven right lobe liver donors were retrospectively reviewed between February 1998 and December 2003. Results : The ages of the donors ranged from 19 to 64 years (median: 46 years). Their body mass index ranged from 16.6 to 34.3 (median: 22.1). The mean duration of the operation was 6.58 (1.25) hours and blood loss was 289 (254) mL. The estimated median donor residual liver volume was 42.2% (range: 20.6-60.3%) and the median hospital stay was 14.5 days (range: 6-267 days). One donor died of liver failure due to small residual liver volume (26%) and steatohepatitis. One hundred and twenty three complications occurred in 104 donors (33.4%). Donors experienced one or more complications. According to the Clavien classification, grade I complications occurred in 71 of the episodes (57.7%), grade II complications in 9 (7.3%), grade IIIa complications in 39 (31.7%), grade IIIb complications in 3 (2.5%), and grade V complications in 1 (0.8%). Biliary complications were the most common and occurred in 37 donors (12%). Conclusion : Right lobe liver donation is a widely accepted procedure that results in the expansion of the indication for LDLT to adults and large children. However, remnant liver size and anatomical variations in the biliary tree represent important risk factors for postoperative complications.
