End-to-end ductal anastomosis in biliary reconstruction: Indications and limitations

Abstract

End-to-end ductal anastomosis is a physiologic biliary reconstruction that is commonly used in liver transplantation and less frequently in the surgical treatment of iatrogenic bile duct injuries. Currently, end-to-end ductal anastomosis is the biliary reconstruction of choice for liver transplantation in most adult patients. In recent years, it has also been performed for liver transplantation in children and in select patients with primary sclerosing cholangitis. The procedure is also performed in some patients with iatrogenic bile duct injuries, as it establishes physiologic bile flow. Proper digestion and absorption as well as postoperative endoscopic access are possible in patients who undergo end-to-end ductal anastomosis. It allows endoscopic diagnostic and therapeutic procedures in patients following surgery. This anastomosis is technically simple and associated with fewer early postoperative complications than the Roux-en-Y hepaticojejunostomy; however, end-to-end ductal anastomosis is not possible to perform in all patients. This review discusses the indications for and limitations of this biliary reconstruction, the technique used in liver transplantation and surgical repair of injured bile ducts, suture types and use of a T-tube. © 2014 Canadian Medical Association.
