title: Septum formation of the common hepatic duct associated with an anomalous junction of the pancreaticobiliary ductal system and gallbladder cancer: report of a case.
abstract: We herein describe a 48-year-old woman who developed a septum formation of the bile duct combined with an anomalous arrangement of the pancreaticobiliary ductal system in conjunction with gallbladder cancer. A preoperative endoscopic retrograde cholangiogram demonstrated a filling defect in the common hepatic duct which was misdiagnosed to be an elevated lesion. Further exploration revealed a septum formation of the bile duct along with gallbladder cancer. A resection of the dilated bile duct and gallbladder along with a dissection of the regional lymph nodes was performed. A histological evaluation showed the septum to consist of a normal bile duct wall while the tumor in the gallbladder was poorly differentiated adenocarcinoma. The patient made an uneventful recovery. The septum formation was presumed to be congenital in origin.
