本文报告１００例胆胰疾病的ＥＲＣＰ与超声内镜（ＥＵＳ）对比研究，结果显示：ＥＲＣＰ诊断胆胰疾病的敏感性与准确性分别为８５％和８６％；ＥＵＳ分别为９６％和９４％；特异性ＥＲＣＰ为９８％、ＥＵＳ为１００％；ＥＵＳ无假阳性；假阴性率ＥＲＣＰ为１５％、ＥＵＳ为８％；与病理结果的总符合率ＥＲＣＲ为８３％、ＥＵＳ为９６％。两种检查方法均无严重并发症。ＥＵＳ尚能判断胆胰恶性肿瘤的进展度，其中淋巴结转移及门脉浸润的判断正确率分别达７０％与８０～１００％，ＥＲＣＰ与ＥＵＳ联合检查与病理结果的总符合率提高到９６％，诊断准确性达９８％。认为ＥＵＳ对胆胰病变的显示及肿瘤进展度的判断优于ＥＲＣＰ，联合ＥＲＣＰ与ＥＵＳ检查能提高胆胰疾病的诊断率。
In this paper, a comparative study of ERCP and endoscopic ultrasonography (EUS) was performed in 100 cases of biliary and pancreatic diseases. The results showed that the sensitivity and accuracy of ERCP in the diagnosis of biliary and pancreatic diseases were 85% and 86%, respectively; EUS was 96% and 94% respectively; Specific ERCP was 98%, EUS was 100%; EUS had no false positive; false negative rate ERCP was 15% and EUS was 8%; The overall coincidence rate with the pathological results was 83%, EUS 96%. There are no serious complications between the two methods. EUS can still judge the progress of gallbladder and pancreas malignancies, in which the correct rate of lymph node metastasis and portal vein infiltration were 70% and 80 ~ 100%, the total coincidence rate of ERCP and EUS joint examination and pathological results increased to 96% Diagnostic accuracy of 98%. EUS of biliary and pancreatic lesions that the display of tumor progression and better than the ERCP, combined with ERCP and EUS examination can improve the diagnosis of biliary and pancreatic diseases.
