AIM
To evaluate the diagnostic value of double-balloon enteroscopy (DBE) for obscure gastrointestinal bleeding (OGIB).
METHODS
The data about 75 OGIB patients who underwent DBE in January 2007-June 2009 in our hospital were retrospectively analyzed.
RESULTS
DBE was successfully performed in all 75 patients without complication. Of the 75 patients, 44 (58.7%) had positive DBE findings, 22 had negative DBE findings but had potential bleeding at surgery and capsule endoscopy, etc. These 66 patients were finally diagnosed as OGIB which was most commonly caused by small bowel tumor (28.0%), angiodysplasia (18.7%) and Crohn's disease (10.7%). Lesions occurred more frequently in proximal small bowel than in distal small bowel (49.3% vs 33.3%, P = 0.047).
CONCLUSION
DBE is a safe, effective and accurate procedure for the diagnosis of OGIB.
目的
评估双气囊小肠镜（DBE）对不明原因胃肠道出血（OGIB）的诊断价值。
方法
回顾性分析我院 2007 年 1 月至 2009 年 6 月间 75 例 OGIB 患者接受 DBE 的资料。
结果
75 例患者均成功完成 DBE，无并发症。75 例患者中，44 例（58.7%）DBE 检查结果阳性，22 例 DBE 检查结果阴性，但手术及胶囊内镜等检查有潜在出血，66 例最终诊断为 OGIB，最常见病因是小肠肿瘤（28.0%）、血管发育不良（18.7%）和克罗恩病（10.7%）。病变更常发生于近端小肠而非远端小肠（49.3% vs 33.3%，P = 0.047）。
结论
DBE 是诊断 OGIB 的一种安全、有效、准确的方法。
