Surgical treatment of hilar bile duct carcinoma. Clinical and pathological studies.

Resection of the extrahepatic bile tract for hilar bile duct carcinoma was performed at the PLA General Hospital, with a resectability rate of 62% (31/50) and no operative mortality. Hepatic lobectomy was performed at the same time in 16 cases (51.6%). Reoperative resections were successfully done in 5 cases; 4 cases are still living 1-4 years after the second operation. The cause of late death was mainly biliary infection due to local recurrence and bile duct obstruction. The median survival period was 15 months. 32 cases were studied pathologically, of which 27 were resected surgical specimens and 5 autopsies. The tumors were histologically classified into 4 types: papillary adenocarcinoma (6 cases); well differentiated adenocarcinoma (21); poorly differentiated adenocarcinoma (3); and simple carcinoma (2). The importance of early diagnosis of hilar bile duct carcinoma at its subclinical stage before appearance of clinical jaundice is stressed.
