Biliary Complications in Recipients of Living-Donor Liver Transplant: A Single-Center Review of 120 Patients.

OBJECTIVES
Biliary complications are common after living-donor liver transplant. This retrospective study reviewed our experience with biliary complications in recipients of living-donor liver transplant.


MATERIALS AND METHODS
Over our 9-year study period, 120 patients underwent living-donor liver transplant. Patients were divided into 2 groups, with group A having biliary complications and group B without biliary complications. Both groups were compared, and different treatment modalities for biliary complications were evaluated.


RESULTS
Group A included 45 patients (37.5%), whereas group B included 75 patients (62.5%). Biliary complications included bile leak in 17 patients (14.2%), biliary stricture in 11 patients (9.2%), combined biliary stricture with bile leak in 15 patients (12.5%), and sphincter of Oddi dysfunction and cholangitis in 1 patient each (0.8%). Cold ischemia time was significantly longer in group A (P = .002). External biliary drainage was less frequently used in group A (P = .031). Technical success rates of endoscopic biliary drainage and percutaneous transhepatic biliary drainage were 68.3% and 41.7%. Survival rate following relaparotomy for biliary complications was 62.5%.


CONCLUSIONS
Graft ischemia is an important risk factor for biliary complications. Bile leaks can predispose to anastomotic strictures. The use of external biliary drainage seems to reduce the incidence of biliary complications. Endoscopic and percutaneous trans-hepatic approaches can successfully treat more than two-thirds of biliary complications. Relaparotomy can improve survival outcomes and is usually reserved for patients with intractable biliary complications.
