胆管癌的CT表现及诊断价值

Manifestations and Diagnostic Value of CT in Cholangiocarcinoma

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.
