The characteristics of the infiltration of bile duct carcinoma along the wall were studied from 25 cases with resection. The histologic mode of the spread of carcinoma was the mucosal infiltration in 1 case, mucosal and transmural infiltration in 2 cases, transmural infiltration in 22 cases. The average distance from the gross margin of the tumor to the margin of spread of growth in the bile duct as determined microscopically was 19.1mm in the direction of the liver (the longest was 85mm), and 5.8mm toward the duodenum (the longest was 20mm).
The distance of the polypoid or nodular type of the gross appearance of the tumor is shorter than that of the infiltrating type. The polypoid type showed inverted U-type in obstructive or stenotic feature of bile duct radiologically and the infiltrating type showed U-type, V-type or constricted type.
The distance of the tubular adenocarcinoma in histological cellular type tended to be longer than that of papillary or undifferentiated type. The severer the invasiorl of the carcinoma to the lymphatic vessels was, the longer the distance was.
