摘要
目的:提高胆管癌CT诊断的正确率,探讨CT及超声对胆管癌的诊断价值。材料和方法:回顾经手术病理证实的64例胆管癌资料,包括CT64例、B超49例。分析病变的CT表现,评价CT和超声对胆管癌的诊断准确率。结果:按胆管癌的发生部位将其分为三类:(1)肝内胆管癌;(2)肝门区胆管癌;(3)胆总管癌。三种类型各有其CT特征。CT确诊率为84%,超声确诊率为86%,CT和超声作为互补的检查方法,其确诊率可达96%。结论:CT和超声互补,可作为胆管癌尤其是肝门区胆管癌和胆总管癌术前可靠的诊断方法。
Purpose: This study was to promote the CT diagnostic accuracy of cholangiocarcinoma and to investigate the usefulness of CT and US in detecting cholangiocarcinoma. Materials and Methods:The records of 64 patients with surgically and pathologically proved cholangiocar cinoma including CT(64 patients)and B-type ultrasonography(49 patients) were reviewed retrospectively. CT manifestations and diagnostic accuracy of both CT combined with US were analysed. Results: The cholangiocarcinomas were classified into three types according to anatomic locations: (1)intrahepatic cholangiocarcinoma;(2)hilar cholangiocarcinoma; (3)common bile duct cholangiocarcinoma. Some CT patterns were quite characteritic in each of the three types. The tumors were correctly revealed by CT in 84% of patients,by US in 86% and by CT together with US in 96%. Conclusion: CT and US used as complementacy procedures were proved to be reliably preoperative examination methods in detecting cholangiocarcinoma especially the hilar and common bile duct cholangiocarcinomas.
