Analysis of early relaparotomy following living donor liver transplantation

We retrospectively analyzed the causes, risk factors, and impact of early relaparotomy after adult-to-adult living donor liver transplantation (LDLT) on the posttransplant outcome. Adult recipients who underwent initial LDLT at our institution between August 1997 and August 2015 (n = 196) were included. Any patients who required early retransplantation were excluded. Early relaparotomy was defined as surgical treatment within 30 days after LDLT. Relaparotomy was performed 66 times in 52 recipients (a maximum of 4 times in 1 patient). The reasons for relaparotomy comprised postoperative bleeding (39.4%), vascular complications (27.3%), suspicion of abdominal sepsis or bile leakage (25.8%), and others (7.6%). A multivariate analysis revealed that previous upper abdominal surgery and prolonged operative time were independent risk factors for early relaparotomy. The overall survival rate in the relaparotomy group was worse than that in the nonrelaparotomy group (6 months, 67.3% versus 90.1%, P
