Double-barrel common bile duct: a rare cause of extrahepatic biliary obstruction.

ABSTRACT

Double-barrel common bile duct is rare. We report a 50-year-old woman with defective canalization of the common bile duct, presenting with extrahepatic biliary obstruction due to stones in one compartment. CT scan highlighted this anomaly. After failed attempts at stone extraction at ERCP, she was successfully operated on.
