超声内镜与CT诊断壶腹周围病变的价值比较

The comparison of diagnostic value between endoscopic ultrasonography and computer tomography in periampullary lesions

目的:探讨并比较超声内镜(EUS)与腹部CT在壶腹周围病变中的诊断价值。方法:收集2009-2013年在我院疑诊壶腹部周围病变的病例,入选病例同时行EUS及腹部CT检查。比较两种方法对壶腹周围不同病变的诊断准确率。结果:确诊为壶腹部周围病变的病例共计151例,包括:胆总管结石、壶腹部肿瘤、壶腹部炎症、胰头肿瘤、胰腺囊肿,超声内镜对上述病变的诊断准确率分别83.6%、90.6%、56.5%、100.0%、100.0%,腹部CT对上述病变的诊断准确率分别为52.2%、56.3%、43.5%、91.3%、100.0%。超声内镜对壶腹部病变总的诊断准确率为84.1%,明显高于腹部CT(59.6%)。结论:EUS对壶腹部周围病变具有很高的诊断价值,诊断准确率高于腹部CT。

Objective To investigate the value of endoscopic ultrasonography （EUS） and abdominal CT （CT） in diagnosis of periampullary lesions and to make comparison between the two procedures. Methods The patients suspected of surrounding lesions of ampullary from 2009 to 2013 in our hospital were included in this study. All the patients received both EUS and abdominal CT. The accuracy rate of these two examination methods was compared. Results 151 patients were confirmed as surrounding lesions of ampullary, including choledocholithiasis, ampullary tumors, ampullary inflammation, tumors of the pancreatic head and pancreatic cysts. The accuracy rate of these diseases was 83.6%, 90.6%, 6.5%, 100.0%, and 100.0%for EUS;while was 52.2%, 56.3%, 43.5%, 91.3%, and 100.0%for abdominal CT. The tatal accuracy rate for diagnosing periampullary lesions by EUS was significantly higher than that by abdominal CT （84.1% vs. 59.6%）. Conclusions Endoscopic ultrasonography has higher value in diagnosis of periampullary lesions, and its accurate rate was higher than that of abdominal CT.
