BACKGROUND: Biliary complications continue to be the "Achilles heel" of living-donor liver transplantation (LDLT). The use of biliary stents in LDLT to reduce biliary complications is a controversial issue. We performed a randomized trial to study the impact of intraductal biliary stents on postoperative biliary complications after LDLT. STUDY DESIGN: Of the 94 LDLTs that were performed during a period of 16 months, ABO-incompatible transplants, left lobe grafts, 3 or more bile ducts on the graft, and those requiring bilioenteric drainage were excluded. Eligible patients were randomized to either a study arm (intraductal stent, n = 31) or a control arm (no stent, n = 33) by block randomization. Stratification was done, based on the number of ducts on the graft requiring anastomosis, into single (n = 20) or 2 ducts (n = 44). Ureteric stents of 3F to 5F placed across the biliary anastomosis and exiting into the duodenum for later endoscopic removal at 3 months were used. The primary end point was postoperative bile leak. RESULTS:Bile leak occurred in 15 of 64 (23.4%), the incidence was higher in the stented group compared with the control group (35.5% vs 12.1%; p = 0.03). Multiplicity of bile ducts and stenting were identified as risk factors for bile leak on multivariate analysis (p = 0.031 and p = 0.032). During a median follow-up of 2 years, biliary stricture developed in 9 patients (14.1%). Postoperative bile leak is a significant risk factor for the development of biliary stricture (p = 0.003). CONCLUSIONS: Intraductal transanastomotic biliary stenting and multiplicity of graft ducts were identified as independent risk factors for the development of postoperative biliary complications.
