PTC of 225 patients(126men,99women)with extrahepatic biliary obstructions proved by histopathology and operation were retrospectively reviewedof 225 patients there were 153 cholangiolethiasises、40 biliary tumors、8 carcinomas of the pancreatic head、4 carcinomas of the Ampulla、3 biliary cysts、13 biliary stenosis and 4 othersPTC showed the location、shape and degress of obstruction and the dilatation proximal to obstructionDilated extrahepatic bile duct ending abruptly or narrowing sharply with mass at the obstructed portion was typical of malignancy where gradual tapering of common bile at the obstructed level usually indicates benign natureMinor or mild degress of dilated intrahepatic bile ducts was usually found in benign diseases and marked or severe degress of dilatation in malignant lesions
