Biliary reconstruction following right adult living donor liver transplantation end-to-end or end-to-side duct-to-duct anastomosis

BACKGROUND AND AIMS: Bile duct complications are the modern Achilles' heel of adult-to-adult living donor liver transplantation. A duct-to-duct anastomosis is currently performed in the presence of single graft ducts, while cholangiojejunostomy is used to drain multiple ducts. Our aim is to describe the feasibility of duct-to-duct anastomoses independent of the presence of one or multiple graft bile ducts. METHODS: The probe technique for right bile duct dissection in donors and a proximal hilar bile duct division in recipients are illustrated. The BARIGA LDLT (biliary anastomosis in right graft for adult living donor liver transplantation recipients) with end-to-side or end-to-end hepatico-hepaticostomy was used in five recipients of right grafts (segments 5-8). RESULTS: All donors and recipients are doing well; all grafts are functional at 13 months. Duct-to-duct anastomoses to single, double, or triple graft ducts have been performed. Two early anastomotic stenoses at 5 and 10 weeks were successfully treated endoscopically. CONCLUSION: The duct-to-duct anastomosis represents a valid alternative to the standard hepaticojejunostomy for right living donor liver grafts. Using this method, biliary complications can be treated endoscopically. End-to-side or end-to-end BARIGA LDLT has the potential to become a standard method in segmental transplantation, including split liver.
