MRCPERCP对胆道梗阻疾病的对比研究

A Comparative Study on MRCP and ERCP in the Diagnosis of Biliary Obstruction

目的:探讨磁共振胰胆管成像(MRCP)及内镜逆行胰胆管造影(ERCP)对胆道梗阻的诊断价值。方法:回顾性分析50例临床怀疑胆道梗阻患者的MRCP资料,并与ERCP相比较,所有病例均经手术病理证实。结果:MRCP对胆道梗阻疾病诊断准确性、敏感性、特异性分别为88%、85.7%、100%,ERCP为100%,两者图像极为相似,具有良好的一致性。结论:MRCP在诊断胆胰管疾病方面简便、安全、无创伤性、无需造影剂,而且具有与ERCP相同的诊断价值,在很多方面可取代ERCP的诊断作用。

Objective To detect the diagnostic values of pancreatobiliary obstructive disease with MRCP and MRCP. Methods The MRCP data of 50 cases suspected biliary obstruction were studied and compared with ERCP. All cases were confirmed by operation and pathology. Results The diagnostic accuracy and sensitivity and specificity rate of M RCP was 88% ,85.7 %, 100 %, that of ERCP was 100%, and the images of MRCP were similar to those of ERCP. The same diagnosis was made based on MRCP. Conclusion MRCP not only is simple, safe,noninvasive and not require contrast material in evaluating the biliary and pancreatic duct but also offers a diagnostic value equivalent to that of ERCP. It is like lytore place ERCP in many diagnostic fields.
