title: Angiographic changes in the hepatic artery after skeletonization resection for biliary tract cancer.
abstract: Using preoperative and postoperative arteriography, angiographic changes in the hepatic artery were studied after skeletonization of the hepatoduodenal ligament and hepatic resection for biliary tract carcinoma. Of 52 patients evaluated (32 with carcinoma of the bile duct, 20 with gallbladder cancer), no angiographic changes were apparent after operation in 30 (58 per cent) and there were pathological findings in 22 (42 per cent; smooth stenosis in five patients, irregular stenosis in seven, a beaded appearance in four, dilatation in two, obstruction in four). Based on angiographic findings, patients were classified into three subgroups (no change, 30 patients; irregular form, 18; obstructed, four). Postoperative liver function was also evaluated. No definite correlation was evident between angiographic findings and the incidence of hepatic failure or liver dysfunction in the first month after operation. Given that connective tissue and lymph node dissection in the hepatoduodenal ligament is essential for curative resection of biliary tract carcinoma, these findings suggest that skeletonization is an acceptable operative procedure.
