磁共振胰胆管造影与内镜逆行胰胆管造影在胆道梗阻病变中的对比研究

A comparison between endoscopic retrograde and magnetic resonance cholangiopanc.reatography for the diagnosis of biliary obstruction diseases

目的评价磁共振胰胆管造影（MRCP）与内镜逆行胰胆管造影（ERCP）在胆系梗阻性病变中的应用价值。方法收集经手术病理证实的胆系梗阻性病变36例，以其手术病理结果为标准，回顾性阅读MRCP及ERCP的影像资料，对照其诊断结果的差异，分析MRCP及ERCP在胆系梗阻性病变诊治中的作用。结果36例胆系梗阻性病例中，胆系肿瘤16例，胆系结石15例，其他胆系病变5例。MRCP与ERCP对胆系梗阻病因诊断的准确性分别为86．1％及91．7％，两者之间差异无统计学意义（P〉0．05）；ERCP检查显示不佳的病例，MRCP检查获得了较为满意的诊断信息。结论MRCP对胆系梗阻性病变能进行准确的定位和相对准确的定性诊断，可作为胆系梗阻性病变病因诊断的首选检查方法。

Objective To evaluate the value of magnetic resonance cholangiopancreatography（MRCP） in the diagnosis of biliary obstruction diseases by comparison with endoscopic retrograde cholangiopancreatography （ERCP）. Methods A total of 36 patients with biliary obstruction diseases underwent both MRCP and ERCP. To review the images obtained from ERCP and MRCP, the diagnosis were compared according to pathology. MRCP and ERCP in the diagnosis and treatment of biliary obstruction disease were analysed. Results 36 patients including 16 biliary tumors, 15 cholelithiases,and five other diseases were analysed. The diagnosis accuracy of MRCP and ERCP for biliary obstruction diseases were 86.1% and 91.7 %, there was no significant difference（P 〉 0.05）. Conclusion MRCP can accurately define the obstructively sites, identify the obstructive causes and is a noninvasive and reliable examination for biliary obstruction diseases.
