胶囊内镜对不明原因消化道出血疾病的诊断及安全性研究

Diagnostic value and clinical safety of capsule endoscopy for obscure gastrointestinal bleeding

目的探讨胶囊内镜在不明原因消化道出血的诊断价值及其安全性。方法对52例疑诊为不明原因消化道出血患者行胶囊内镜检查并总结分析。结果 52例患者中,50例患者顺利完成胶囊内镜检查,检查成功率为96.2%。2例胶囊滞留,经外科手术取出。共发现小肠病变31例,阳性率59.6%。其中,可疑肿物2例、血管性出血2例、溃疡或多发黏膜糜烂14例、寄生虫6例、小肠淋巴滤泡增生3例、小肠憩室1例,新鲜出血影响视野观察3例。结论胶囊内镜对不明原因消化道出血的检出率高,安全性好,可作为不明原因消化道出血的重要检查手段。

Objective To evaluate the diagnostic value and clinical safety of capsule endoscopy for obscure gastrointestinal bleeding. Methods 52 patients suffering from obscure gastrointestinal bleeding were examined by capsule endoscopy. Results Among 52 patients,50 completed the examination of capsule endoscopy,with the successful rate of 96. 2%. Capsule retention occurred in 2 patients,which was removed by surgery. Pathological changes were detected in 31 ones,with the positive rate of 59. 6%. The findings included 2 cases of suspicious lesions,2 cases of vascular bleeding,14 cases of ulcer and inflammation,3 cases of lymphoid hyperplasia,1 case of diverticulum,and 3 cases of active bleeding influencing visual observation. Conclusion Capsule endoscopy is safe and valuable for the diagnos of the obscure gastrointestinal bleeding.
