Biliary bypass for an "accessory" biliary duct. A case report

A case of accessory biliary duct draining segments V and VI of the liver, accidentally injured during cholecystectomy and repaired by biliary-enteric anastomosis, is reported. An accessory bile duct may occur in 15-20% of these patients. Ligation or repair is always recommended depending on the size and volume of bile flow. Roux-en-Y loop reconstruction is to be preferred as it provides the best results with the lowest risk of leakage, stenosis and cholangitis.
