Donor morbidity including biliary complications in living-donor liver transplantation: a single center analysis of 283 cases.

BACKGROUND Because of the shortage of deceased-donor livers for transplantation, living-donor liver transplantation (LDLT) has become an indispensible treatment strategy for end-stage liver disease. The critical prerequisite for LDLT is the maximal safety of healthy donors. METHODS From June 1996 to November 2010, a total of 827 completed donor hepatectomies were performed in our center. We analyzed donor morbidity associated with LDLT. RESULTS There was no donor mortality. No complications were observed in 744 (90.0%) donors, and 83 (10.0%) donors experienced complications. Wound complications were most common, occurring in 48 (5.8%) patients. According to a modified Clavien classification, grade I, grade II, grade IIIa, and grade IIIb complications were experienced in 56 (67.5%), 2 (2.4%), 15 (18.1%), and 10 (12.0%) donors, respectively. Surgical or interventional management was successful in all grade IIIa and grade IIIb donors. The incidence of biliary complications was significantly higher in younger donors. Donor morbidity did not decrease below the attained level even after time had passed. CONCLUSIONS This study demonstrates the safety of donor hepatectomy. Complications were relatively minor and easily controlled. The incidence of biliary complications and donor age was inversely correlated. The procedural experience of the surgeons was not associated with the donor complication rate.
