Özet

Duplicated common bile duct, often associated with conditions like lithiasis, biliary cysts and pancreatobiliary maljunction, could result in highly morbid and potentially fatal biliary injuries. Precise preoperative diagnosis and classification still remain a challenge. A female patient undergoing emergency laparoscopic cholecystectomy for acute calculous cholecystitis sustained iatrogenic bile duct injury. A drainage tube was placed into the injured duct for post-operative conservative management. Post-operative tube cholangiogram revealed a double common bile duct with cystic duct opening distally. This was identified as a new variant not previously reported or classified. However rare, duplicated common bile duct could result in serious iatrogenic bile duct injury if unidentified during surgery. Knowledge of its existence is essential to avoid such injuries as preoperative diagnosis still remains a challenge. A thorough clinical and morphological study of previously reported variants is needed for a comprehensive classification to encompass newly discovered variants.
