Diagnostic value of the cholangiography was studied for carcinoma of the biliary tract involving the hepatic hilus, and special attention was paid on the cholangiogram of the bile duct branches (B1) of the caudate lobe. Cholangiograms of BI were compared with pathologic findings in 42 (27 bile duct carcinomas, 15 gallbladder carcinomas) of 43 cases of biliary tract carcinomas. Sixty-four of B1 in the 42 cases could be studied radiologically and histopathologically.
The findings of the root of B1 were classified into 4 groups: group A, not stenotic; group B, short segmental stenosis; group C, long segmental stenosis and group D, poorly imaged. Carcinoma invasion was found in 6 of 18 of group B, and in 9 of 16 of group C. Carcinoma was confirmed near the root of B1 in the remaining 7 of the 16 of group C. Carcinoma invasion was found in 20 of 21 of group D, and invasion was suspected in the remaining one.
Carcinomas were found in the root of B1 in all cases of poorly imaged or long segmental stenosis of B1, and in 33% of short segmental stenosis of B1. Therefore caudate lobe resection should be performed for carcinoma of the biliary tract involving the hepatic hilus.
