目的 评价磁共振胰胆管成像（MRCP）与经内镜胰胆管造影（ERCP）对梗阻性黄疸的诊断价值。方法 对32例梗阻性黄疸患者先后进行MRCP与ERCP检查,所有诊断均经手术或病理证实。结果 MRCP与 ERCP对梗阻的定位准确率分别为 90.6％（29/32）及 82.8％（24/29）,两者差异无统计学意义（P=0.5960）,合并两者检查的准确率为96.9％（31/32）,与单项 MRCP（P=0.3010）、ERCP（P=0.0643）准确率差异无显著性意义。MRCP与ERCP对梗阻的定性诊断准确性分别为75.0％（24/32）及72.4％（21/29）,两者间差异无显著意义（P=0.9503）,合并两者检查的准确率为 93.8％（30/32）,高于 MRCP（P=0.0387）或ERCP（P=0.0245）单项检查。结论MRCP与ERCP都是有效、安全的诊断梗阻性黄疸的方法,MRCP与ERCP相结合诊断准确率可进一步提高。
Objective To evaluate the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) and endoscopic cholangiopancreatography (ERCP) for obstructive jaundice. Methods Thirty-two patients with obstructive jaundice were examined by MRCP and ERCP successively, and all the diagnoses were confirmed by surgery or pathology. Results The accuracy of location of MRCP and ERCP on obstruction was 90.6% (29/32) and 82.8% (24/29) respectively, with no significant difference (P = 0.5960). The accuracy of MRCP and ERCP was 96.9 % (31/32). There was no significant difference between single MRCP (P = 0.3010) and ERCP (P = 0.0643). The diagnostic accuracy of MRCP and ERCP for obstruction was 75.0% (24/32) and 72.4% (21/29) respectively, with no significant difference between the two (P = 0.9503). The accuracy of the combined diagnosis of MRCP and ERCP was 93.8 % (30/32), higher than MRCP (P = 0.0387) or ERCP (P = 0.0245) single check. Conclusion Both MRCP and ERCP are effective and safe methods to diagnose obstructive jaundice. The diagnostic accuracy of MRCP and ERCP can be further improved.
