胆胰疾病的超声内镜与ERCP对比研究

A Comparative study between EUS and ERCP for diagnosing the choledochal and Pancreatic Diseases.

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;假阳性率ERCP为15％,EUS为8%;与病理结果的总符合率ERCP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联合检查使病理结果的总符合率提高到96％,诊断准确性达98%。作者认为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。

We reported a comparative study between EUS ant ERCP for diagnosing 100 cases of choledochal and pancreatic diseases. The results showed: The sensitivity, accuracy, specificity and false negative rate were 85%,86% , 98% and 15% in ERCP respectively,but 96% ,94% , 100% , and 8% in EUS respectively. There was no false positive rate in EUS. The total corresponding rate of ERCP was 83% and EUS was 96%. The diagnostic accuracy was as follows: lymph nodes metastases was 70% and portal vein infiltration was 80-100%. EUS was superior to ERCP in imaging the choledochal and pancreatic mass lessions and preoperat-ivc diagnosing the carcinoma.
