Abstract
The purpose of the present study was to evaluate the resectability of the cases of bile duct carcinoma of the hepatic hilus. Among the cases experienced from July,1978 to December,1986, we evaluated 49 cases (34 resectable and 15 non-resectable) by the findings of cholangiography, arteriography and portography.
The results were as follows:
The resectability was mainly determined by the findings of arteriography and portography. Those cases which presented no abnormal arteriographic findings at the proper, right and left hepatic arteries, were all resectable, and 80% of the case, having unilateral tumor-invasive findings at the right or left heptic artery, could be resected. However, when there existed further more encasements at the proper, right and left hepatic arteries, no resection could be performed. By the findings of portography, those cases which had no invasive findings at the main trunk of the portal vein and bilateral portal branches were all resectable. However, if there were tumor-invasive findings at the main trunk of the portal vein, no cases were resectable. Seventythree percent of the cases which had only unilateral invasive findings at the right or left portal branch were resectable.
