胶囊内镜对于不明原因消化系出血与小肠血管发育不良的诊断价值

Diagnostic value of capsule endoscopy for obscure gastrointestinal bleeding and intestinal angiodysplasia

目的:探讨胶囊内镜对小肠血管发育不良的临床诊断价值,为该类小肠血管病变的临床诊断提供参考手段.方法:选择2008-02/2013-11我院收治的不明原因消化系出血患者180例为研究对象,经胶囊内镜对其出血原因进行检查.对检出的血管发育不良患者进行单气囊小肠镜复检,以对小肠血管发育不良进一步确诊,并验证胶囊内镜对小肠血管发育不良的诊断率.结果:经胶囊内镜检查,180例患者的出现原因主要为小肠血管发育不良、克罗恩病、胃肠间质瘤等,检出小肠血管发育不良38例.小肠血管发育不良患者的单气囊复检结果与胶囊内镜结果一致,小肠血管发育不良的阳性检出一致率为97.37%.结论:胶囊内镜可有效查明不明消化系出血患者的病因,且对小肠血管发育不良具有较高的临床诊断价值,可与单气囊内镜相比拟.

AIM： To explore the clinical value of capsule endoscopy for the diagnosis of obscure gastrointestinal bleeding （OGIB） and intestinal angiodysplasia. METHODS： One hundred and eighty patients with OGIB treated at our hospital from February 2008 to November 2013 were included in the study. Causes of bleeding were analyzed by capsule endoscopy. The patients with intestinal angiodysplasia underwent single balloon enteroscopy to verify the accuracy of capsule endoscopy for the diagnosis of intestinal angiodysplasia. RESULTS： Causes of bleeding were small bowel angiodysplasia, Crohn＇s disease, and gastrointestinal stromal tumors. A total of 38 cases of intestinal angiodysplasia were diagnosed by capsule endoscopy. The concordance rate of diagnosis of intestinal angiodysplasia by capsule endoscopy and single balloon enteroscopy was 97.37%. CONCLUSION： Capsule endoscopy can effectively diagnose OGIB and has a highly diagnostic value for intestinal angiodysplasia, which is comparable to single balloon endoscopy.
