Predictors of Biliary Leakage After T-Tube Removal in Living Donor Liver Transplantation Recipients

•Biliary leakage developed in 9 (22.5%) patients after T-tube removal.•Number abdominal surgeries performed ≥2 and duration of T-tube placement <8 months were predictive of biliary leakage after T-tube removal in living donor liver transplantation recipients.•Biliary leakage after T-tube removal is associated with significant morbidity in LDLT recipients.

BackgroundBiliary leakage after T-tube removal is a frequent cause of morbidity in liver transplant recipients. The aim of this study was to determine the factors that predict the development of biliary leakage after T-tube removal in living donor liver transplantation (LDLT) recipients.MethodsOf the 144 patients who underwent LDLT with right-lobe liver grafts during the period January 2007 to May 2013 at a single medical center, 40 received biliary anastomosis with T-tube placement. Subjects were grouped into either a biliary leakage or non-biliary leakage group on the basis of the presence or absence of abdominal symptoms associated with signs of peritoneal irritation after T-tube removal. Recipient, graft, operative, and postoperative factors were included in a forward, stepwise multiple logistic regression model to identify the most important risk factors for biliary leakage after T-tube removal.ResultsBiliary leakage developed in 9 (22.5%) patients after T-tube removal. Risk factors associated with biliary leakage included the number of abdominal surgeries performed [odds ratio (OR) = 12.6, 95% confidence interval (CI): 2.1–20.4] and duration of T-tube placement (OR = 6.9, 95% CI: 1.2–10.7).ConclusionsBiliary leakage after T-tube removal is associated with significant morbidity in LDLT recipients. We suggest that T-tube placement be used sparingly in LDLT biliary reconstruction. When used, a T-tube should not be removed earlier than 8 months after placement, especially in recipients who have received primary abdominal surgery.
