Bile Leakage after Liver Transplantation

Abstract Objective To evaluate the risk factors and outcome of bile leak after liver transplantation. Methods We undertook a retrospective study of patients who underwent liver transplantation in our institution between January 2010 and January 2014. The characteristics and survival rate of patients with or without bile leak were compared. Results Bile leak was observed in sixteen patients after liver transplantation (2.7% of the total number of patients transplanted). Total operating time and bile duct reconstruction technique (duct-to-duct anastomosis or Rouxen-Y cholangiojejunostomy) were found to differ significantly between patients with and without bile leak in univariate (p = 0.001 and 0.024, respectively) and multivariate analyses (p = 0.012 and 0.026, respectively). There was no difference in the one-year patient survival rate between the two groups. However, two-year patient survival rate was significantly lower in the bile leak group (p = 0.003). Both one-year and two-year graft survival rates were significantly lower in the bile leak group (p = 0.049 and <0.001, respectively). Conclusions Cholangiojejunostomy and prolonged total operating time are risk factors for bile leak after deceased donor liver transplantation. Bile leak reduces graft and patient survival rates after deceased donor liver transplantation.
