Abstract

Bile duct way stenosis mimic malignant such as cholangiocellular carcinoma lesions and gall bladder carcinoma invasion. A 74-year-old woman a gallbladder (GB) polyp combined with common hepatic duct (CHD) stenosis was found in admitted for surgery to treat. Preoperative evaluation revealed to have a polypoid tumor 12 mm in diameter and relatively smooth CHD stenosis. Because the possibility of malignancy could not be excluded, she underwent open abdominal surgery. We conducted the usual cholecystectomy. The CHD was compressed by the cystic artery, so we thoroughly confirmed the absence of any suspicious CHD lesion by directly inspecting the inner side of the stricture by choledochotomy. The definitive diagnosis of the GB tumor was early GB carcinoma. Although CHD compression by the cystic artery is considered uncommon, we suggest that it should be included in the differential diagnosis of extrahepatic biliary stenosis, especially when biliary stenosis is relatively smooth.
