目的 :评价内窥镜逆行胆胰管造影的诊断价值。方法 :对 63例肝外胆管梗阻性疾病进行内窥镜逆行胆胰管造影 (ERCP)检查 ,取不同角度体位摄片与磁共振胆胰管造影资料( 1 ) (MRCP)进行对比。结果 :ERCP检查一次性成功率为 89% ,失败率 11% ,定位诊断准确率为 10 0 % ,对梗阻的原因诊断准确率为 89.3 %。MRCP检查 5 4例均一次成功 ,对肝外胆管梗阻的定位诊断和定性准确率分别为 10 0 %、88.9%。结论 :ERCP与MRCP在对肝外胆管梗阻的定位、定性诊断准确率大致相近。对肝外胆管梗阻检查为明确病因ERCP检查可作为首选 ,在ERCP检查失败或病情较重患者可行MRCP检查。
Objective: To evaluate the diagnostic value of endoscopic retrograde cholangiopancreatography. Methods: 63 cases of extrahepatic bile duct obstructive disease were examined by endoscopic retrograde cholangiopancreatography (ERCP). The radiography and magnetic resonance cholangiopancreatography data (1) were compared with MRCP. Results: The one-time success rate of ERCP was 89%, the failure rate was 11%, the accuracy of localization diagnosis was 100%, and the diagnosis accuracy of obstruction was 89.3%. MRCP examination of 54 cases were successful, the diagnosis and qualitative accuracy of the diagnosis of extrahepatic bile duct obstruction were 100%, 88.9%. Conclusion: The accuracy of ERCP and MRCP in diagnosing extrahepatic bile duct obstruction is similar. The diagnosis of extrahepatic bile duct obstruction as a clear cause of ERCP examination can be used as the first choice in patients with ERCP examination failed or serious MRCP examination.
