Abstract:
Twenty-four cases of carcinoma of biliary duct, 6 of carcinoma of gallbladder and 19 of carcinoma of Vater's ampulla are reported. All of those 49 cases were con- firmed by operation and/or pathology.The diagnostic accuracy by endoscopic retragra-de cholangiopancreatography(ERCP)was 85.7%.The radiological appearances of carcinoma of biliary tract under ERCP were described and classified into 3 types, namely obstruction,stricture and polypoid types. The stricture type was further divided into 3 subtypes of occlusive,annular and diffuse stenosis.The obstruction type and occlusive stenosis type were more common. Carcinoma of gallbladder manifested as a constant filling defect with a wide base in the gallbladder, while carcinoma of ampulla as an irregularly bordered space occupying lesion in it, which could obstruct the biliary duct and/or pancreatic duct. The soft rattan-form change in intrahepatic biliary ducts was the characteristic manifestation of malignant tumor of biliary tract.
