MRCP与ERCP对胆胰系疾病诊断价值比较

目的评价磁共振胰胆管显影(MRCP)与经内镜逆行胰胆管造影(ERCP)对胆胰系疾病的诊断价值. 方法 40例疑有胆胰系疾病患者均行MRCP和ERCP检查,比较两者结果. 结果 40例MRCP、ERCP胰管、胆管均显影.MRCP敏感度87%(34/39),特异度100%(1/1),准确度88%(35/40);ERCP敏感度100%(39/39),特异度100%(1/1),准确度100%(40/40).两者相比较,统计学上无差异. 结论 ERCP和MRCP诊断胆胰系疾病准确率无差异,但在明确梗阻性黄疸病因方面,目前MRCP尚不能取代ERCP.

A comparison between endoscopic retrograde and magnetic resonance cholangiopancreatography for the diagnosis of pancreaticobiliary diseases

Objective To determine how endoscopic retrograde cholangiopancreatography (ERCP) compared with magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of pancreaticobiliary diseases. Methods A total of 40 patients with suspected pancreaticobiliary diseases underwent both MRCP and ERCP. Images obtained from ERCP and MRCP were compared. Results Pictures of both the examinations in the 40 patients had come out satisfactorily revealing the pancreatic duct and the biliary tree. The sensitivity, specificity and accuracy were 87% (34/39), 100% (1/1) and 88% (35/40) in MRCP and 100% (39/39), 100% (1/1) and 100% (40/40) in ERCP, respectively, without significant differences between the two examinations. Conclusions Although MRCP offers a diagnostic means equivalent to ERCP, it cannot take the place of the latter as regards identification of biliary obstruction.
