Abstract
We report a very rare case of cancer of the remnant cystic duct after cholecystectomy. A 60s-years-old woman was admitted for the stone in the common bile duct who was followed for diabetus mellitus and chronic hepatitis C. She underwent cholecystectomy for gallbladder stone at thirty-four years old. ERCP showed that there is no stone in the common bile duct and the remnant cystic duct was detected and a filling defect of right side of the upper bile duct. Biopsy specimen of the wall of the upper bile duct was adenocarcinoma. Abdominal angiography revealed the cystic artery from the right hepatic artery and tumor stain. We diagnosed cancer of the remnant cystic duct and extrahepatic bile duct resection was performed. The resected specimen revealed tumor was located in the remnant cystic duct and invaded the upper bile duct. The tumor consisted of moderately differentiated adenocarcinoma. We diagnosed cancer of the remnant cystic duct finally. The patient is alive nine months after surgery without recurrence.
