【摘要】 本文分析２２５例肝外胆管梗阻病变患者ＰＴＣ表现。其中男１２６例，女９９例，其中胆石症１５３例、胆管肿瘤４０例、胰头癌８例、壶腹癌４例、胆管囊肿３例、胆管狭窄１３例、其它４例。２２５例均经手术、病理证实。ＰＴＣ表现病变部均有不同程度的梗阻及梗阻以上胆管扩张，梗阻端形态多样。良性病变多表现为不完全性梗阻，扩张胆管多为轻、中度，胆内末梢胆管充盈差，数目减少，梗阻端呈光滑的杯口状及狭窄段病变呈渐移性狭窄，范围较大，边缘较光滑、柔软；恶性病变多表现为完全性梗阻，梗阻端呈截断状、鸟嘴状、平削状、圆锥状、狭窄段胆管不规则、僵硬及与正常段分界截然，肝内胆管中、重度扩张至末梢胆管、呈“软藤状”更多还原

【Abstract】 PTC of 225 patients(126men,99women)with extrahepatic biliary obstructions proved by histopathology and operation were retrospectively reviewedof 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 othersPTC showed the location、shape and degress of obstruction and the dilatation proximal to obstructionDilated 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 natureMinor or mild degress of dilated intrahepatic bile ducts was usually found in benign diseases and marked or severe degress of dilatation in malignant lesions更多还原
