摘要
本文对比分析了８２例恶性梗阻性黄疸（包括胆管癌４５例，转移性癌２６例，胰头癌６例及壶腹周围癌５例）的ＥＲＣＰ与ＣＴ表现，主要发现：恶性胆管梗阻部位多位于肝外胆管近侧段；肝外胆管近侧段梗阻所致的肝内胆管重度扩张的发生率，远多于远侧段阻塞，在反映肝内胆管扩张程度、扩张范围方面ＣＴ优于ＥＲＣＰ，而显示病灶肿块直接征象方面ＥＲＣＰ优于ＣＴ。
The CT and ERCP features were comparatively analysed in 82 cases of malignant obstructive jaundice caused by biliary primary carcinoma in 45 cases, metastatic carcinoma in 26 cases, and ampulla of Vater carcinoma in 5 cases,as well as pancreatic carcinoma in 6 cases. It was found that the biliary obstruction was mainly located in the proximal segment of extrahepatic bile tract; the incidence of intrahepatic duct dilatation with severe degree caused by obstruction of proximal extrahepatic tract was much higher than that in distal obstruction, On showing the widespread and degree of intrahepatic biliary dilatation,CT is better than ERCP. but on detecting the tumor mass imaging features,ERCP is superior to CT.
