During the 13-year period from 1979 Jan. to 1992 Apr., 93 patients with carcinomas of the biliary tract including the ampulla of Vater and the pancreas were surgically treated at Kumiai General Hospital in the northern Hida district of Gifu Prefecture. In these 93 patients, 31 were diagnosed as suffering from carcinomas of the extrahepatic bile duct; 19, gallbladder carcinomas; 5, carcinomas of the ampulla of Vater and 38, pancreatic carcinomas. But the majority of these patients were classified into the far-advanced stages in accordance with the Japanese stage classification. Resectability was 58.1% in carcinoma of the extrahepatic bile duct, 42.1% in gallbladder carcinoma, 100% in periampullary carcinoma and 31.5% in pancreatic carcinoma and their survival rates were discouragingly low. To improve the postoperative results, it should be advocated that early diagnosis and treatment are most important for biliary tract carcinoma of m and fm in pathological depth, gallbladder carcinoma of m and pm in depth and small pancreatic carcinoma smaller than 2 cm.
