Biliary complications are some of the most critical problems in liver transplantation. Despite various refinements in surgical technique, different types of liver transplantations are associated with significant numbers of biliary problems. In this study, we analyzed the results of biliary reconstructions in 127 liver transplant recipients at our center from April 2001 to May 2006. Through November 2004, we used different techniques for biliary reconstruction in 66 of these patients, including duct-to-duct (DD) anastomoses, Roux-en-Y hepaticojejunostomy (RYHJ), anastomoses over T tubes or stents, and anastomoses without stenting. During the first period, we used a DD anastomosis in 15 cadaveric whole liver grafts and in 25 right lobe and 12 left lobe or left lateral segment grafts from living-related donors. RYHJ was preferred in 2 cadaveric and 12 left lateral segment grafts. Beginning in November 2004, we employed intraoperative transhepatic biliary catheter insertion in 61 patients (29 children, 32 adults). In the most recent 61 cases of 13 liver grafts from cadavers and 48 from living-related donors, 14 patients (2 children and 12 adults) received whole-liver grafts, 22 (all adults) a right lobe, and 26 (all children) a left lateral or left lobe. Intraoperative transhepatic biliary catheter insertion was performed with DD anastomosis in 55 cases and with RYHJ in 6 cases. The mean complication rate decreased from 24% to 8.1% during the period using a new biliary reconstruction technique. Five biliary complications occurred in four patients. The new technique of biliary reconstruction using intraoperative biliary catheter insertion has significantly reduced the biliary complication rate. Transhepatic biliary stenting prevents biliary complications and maintains percutaneous access when problems arise. Intraoperative transhepatic biliary catheter insertion at the back table is a safe way to provide good biliary drainage after liver transplantation.
