目的探讨CT对恶性梗阻性黄疸的诊断价值。方法回顾性分析和总结本院经手术病理证实的45例恶性梗阻性黄疸的CT征象资料。结果本组中肝门胆管癌10例,胆囊癌10例,胆总管下段癌11例,壶腹癌1例,胰头癌7例,十二指肠乳头癌5例,肝尾叶癌1例。恶性胆道梗阻的CT表现有:肝内及肝门部胆管扩张、胆总管扩张,表现为"软藤征","截断征"等。结论CT是诊断梗阻性黄疸的重要方法之一,具有重要的临床价值。CT对梗阻性黄疸有极高的定位与定性诊断价值,但在具体病因确定上有一定局限性。

Objective To study the CT technique in the diagnosis of malignant obstructive jaundice. Mechods The CT signs of 45 cases of malignant obstructive jaundice were proved by surgery and pathology. Results The tumors included hilar cholangio-carcinoma （ n = 10 ）, carcinoma gallbladder （ n = 10 ）, common duct＇ s carcinoma （ n = 11 ）, ampullary adeno carcino- ma （ n = 1 ） , cancer of the head of pancreas （ n = 7 ） , mayor duodenual papilla carcinoma （ n = 5 ） , caudate lobe of liver carcinoma （ n = 1 ）. The CT characters of malignant obstructive jaundice were ：enlarged intrahepatie cholangio and hilar cholangio and en- larged common bile duct. Conclusion CT examination has important value in diagnosing malignant jaundice, and has high accuracy in the locative and qualitative diagnosis of obstructive jaundice. But there is some limitation in determining the specific disease.
