影像学检查对恶性梗阻性黄疸的诊断价值

我院1985～1993年间收治的恶性梗阻性黄疸171例,所有病例均经B型超声（B-us）、内窥镜下逆行胰胆管造影（ERCP）、经皮肝穿刺胆管造形（PTC）及电子计算机断层扫描（CT）等影像学检查,并经手术证实。通过分析比较,详细地讨论了各种影像学检查的优缺点及特点。指出:入院前即完成肝功、B-us检查。对肝内胆管扩张者,采用PTC检查,对不扩张者采用ERCP检查,若ERCP失败,也可改用PTC方法,对于低张十二指肠造影不做为常规的检查方法。

Operation confirmed all diagnoses. Through analysis and contrast, the authors discussed the fea-tures of imagine examinations montioned above. The authors also indicates that examination of B-scan ultrasound and liver function should be finished before admission. If intrahepatic bile duct is dilated, PTC is used; if not dilated, ERCP is selected.
