A Case of Bile Duct Carcinoma with Hemobilia

今回, 我々は胆道出血を伴った胆管癌のまれな症例を経験したので報告する.症例は70歳の男性で, 2003年10月上腹部痛が出現し肝胆道系酵素の上昇と画像診断で胆管拡張を認めたため内科にて経過観察中であった.2004年9月にUSで中部胆管内に中心を置く腫瘤像が認められ, 入院のうえERCPを施行した.血性胆汁を伴う胆管腫瘍の診断で2005年1月肝外胆管切除術を施行した.切除標本病理組織学的所見では中部胆管の低分化型腺癌と診断されstage II, fCurAであった. We report a rare case of cancer of the bile duct with hemobilia. The patient was a 70-year-old male who had been followed up for upper abdominal pain, abnormal biliary enzyme laboratory data, and bile duct dilatations since October 2003. ERCP on September 2004 for closer examination of a bile duct tumor detected by US revealed hemobilia. In January 2005 we performed extrahepatic bile duct resection of fCurA for a preoperative diagnosis of bile duct tumor. Histopathological examination revealed stage II poorly differentiated adenocarcinoma in the middle portion of the bile duct
