目的 比较磁共振胰胆管造影 (MRCP)、超声内镜 (EUS)与内镜逆行胰胆管造影 (ERCP)诊断阻塞性黄疸的价值。方法 39例阻塞性黄疸患者分别行MRCP、EUS和ERCP。MRCP采用重T2加权及超快速自旋回波水成像技术进行 ,EUS和ERCP按常规进行。结果 MRCP、EUS与ERCP诊断准确率分别为 87.2 % (34/39例 )、94.9% (37/39例 )和 97.4% (38/39例 ) ;对恶性狭窄的诊断准确率分别为 6 1.5 % (8/13例 )、84.6 % (11/13例 )和 92 .3 % (12 /13例 ) ;对胆总管结石的诊断准确率均为10 0 .0 % (2 1/2 1例 )。结论 MRCP为无创性检查 ,在明确阻塞性黄疸病因时可作为首选方法 ,目前尚不能取代ERCP。EUS作为诊断胆、胰系统疾病的重要方法 ,与MRCP和ERCP结合 ,能提高阻塞性黄疸诊断的准确率
Objective To compare the value of magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of obstructive jaundice. Methods 39 patients with obstructive jaundice were performed MRCP, EUS and ERCP respectively. MRCP was performed using a weighted T2-weighted and ultrafast spin echo water imaging technique, with EUS and ERCP routinely performed. Results The diagnostic accuracy of MRCP, EUS and ERCP were 87.2% (34/39 cases), 94.9% (37/39 cases) and 97.4% (38/39 cases), respectively. The diagnostic accuracy rates of MRCP, EUS and ERCP were 6 1.5% (8/13 cases), 84.6% (11/13 cases) and 92.3% (12/13 cases). The diagnostic accuracy of common bile duct stones was 100.0% (2 1/2 cases) . Conclusions MRCP is a noninvasive examination, which can be used as the first choice when the etiology of obstructive jaundice is clear. Currently, it can not replace ERCP. EUS as an important method of diagnosis of biliary and pancreatic diseases, combined with MRCP and ERCP, can improve the diagnostic accuracy of obstructive jaundice
