Carcinoma of the bile duct is classified into four types from the view point of surgical pathology: (1) diffuse infiltrating type, (2) intramural infiltrating type, (3) nodular type, (4) papillary type. Among them, the second type has some characteristics compared with others. Fifteen cases of this type were encountered at the First Department of Surgery, Gifu University Hospital since 1959. They were investigated both in clinical and pathological aspects and the following conclusions were obtained.
(1) Obstructed end of the bile duct by neoplastic involvement shows figure of pointed tip of the U-shape on percutaneous transhepatic cholangiogram. (2) Histologic study reveales tumor tissue is highly scirrhous with well differentiated tumor cells. (3) It is not infrequent that tumor cell extends beyond the margin of surgical specimen even when resection was performed in apparently normal portion. (4) Survivors more than two years is occasionally found in the case who had only decompression procedure as a palliative treatment. (5) Even in the case where resection is impossible, decompression of biliary tract by drainage through tumor tissue is feasible because of its biological behaviour.
