ERCP与MRCP对胆胰疾病诊断的比较研究

目的评价磁共振胰胆管成像(MRCP)与经内镜胰胆管造影(ERCP)对胰胆疾病的诊断价值。方法对85例胰胆管疾病患者均进行ERCP和MRCP检查,并经手术和病理证实。结果85例MRCP与ERCP均获成功,其中两者诊断一致53例,不一致32例(37.6%,32/85),诊断一致的胆总管结石36例,肿瘤9例,其他8例。不一致32例中,MRCP诊断为肿瘤、结石32例,而ERCP诊断为结石或未见异常。结论MRCP诊断胆总管扩张的敏感性、准确性较高,对扩张的病因诊断尚不够理想,对胆总管较小结石的诊断不如ERCP敏感及准确,而且不能治疗,因此MRCP不能替代ERCP。

COMPARISON BETWEEN ERCP AND MRCP IN THE DIAGNOSIS OF BILE DUCT AND PANCREATIC DUCT DISEASES

Objective To evaluate magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography in the diagnosis of bile duct and pancreatic tract disease.Method 85 patients confirmed by operation or pathology received MRCP and ERCP.Result All the 85 patients by MRCP and ERCP were successful.The same diagnosis based on MRCP and ERCP was 53 patients.The different diagnosis was 32 patients(37.6%,32/85).Vnsame result 32 cases,MRCP was tumor and stone,ERCP was stone and normal.Conclusion MRCP has a noninvasive diagnostic modality capable of producing high quality imagines of bile duct and pancreatic tract.MRCP has a high sensitivity and specificity in the evaluation of the bile duct and pancreatic tract.The efficacy of MRCP is sufficient to justify its use in the diagnosis of bile duct and pancreatic tract diseases,but not to replace ERCP.
