Seventy-seven-year-old man presented with painless jaundice and work-up revealed mid bile duct stricture. Biliary stent was placed, and bile cytology confirmed the diagnosis of cholangiocarcinoma. The suspected tumor extension was from the hepatic duct confluence down to the pancreatic boarder. He was taken to the OR with the plan for left hepatectomy with caudate lobe and extra-hepatic bile duct resection with/without pancreaticoduodenectomy (PD). With distal bile duct margin by frozen section confirmed negative for cancer, PD was not performed. The operation was completed uneventfully with blood loss of 1200 cc without need for transfusion. His postoperative course was uncomplicated, and he was discharged home. The histological examination showed cholangiocarcinoma involving the confluence down to the distal bile duct. The distal margin was positive for carcinoma in situ. His final pathologic stage was pT2N0M0 and no adjuvant chemotherapy was given.
