双气囊小肠镜与胶囊内镜对不明原因消化道出血诊断价值的研究

Comparative study of double-balloon enteroscopy and capsule endoscopy in diagnosis of obscure gastrointestinal bleeding

目的比较双气囊小肠镜与胶囊内镜对不明原因消化道出血检出率、诊断率和实用价值。方法对2006年10月至2007年10月第三军医大学新桥医院收治的不明原因消化道出血73例患者行双气囊小肠镜检查,经口腔或肛门进镜检查未发现病灶者,改换进镜方式再行检查。另66例行胶囊内镜检查。对比两种检查方式的临床效果。结果双气囊小肠镜组检出率为94.5%,诊断率为80.8%;胶囊内镜组检出率81.8%、诊断率为50.0%。两组患者均能耐受检查。结论双气囊小肠镜组的检出率及诊断率均显著高于胶囊内镜组。而胶囊内镜检查更为简便易行。

Objective To evaluate the diagnostic yield and the etiological accuracy of double balloon endoscopy and capsule endoscopy in patients with. Methods Seventy-three patients with OGIB received double balloon endoscopy. The route of enteroscopy could be either via mouth or via anus. Negative result of initial route was required afterwards for another via mouth or via anus examination. Sixty-one patients with OGIB received capsule endoscopy. Results The overall diagnostic yield for double balloon enteroscopy was 94. 5% ,and for capsule endoscopy it was 81.8%. The etiological diagnostic accuracy of double-balloon enteroscopy was 80. 8% , and for capsule endoscopy ,50. 0%. Double-balloon enteroscopy and capsule endoscopy were both well tolerated. Conclusion Double balloon enteroscopy is superior to capsule endoscopy in the diagnostic yield and the etiological diagnosis of obscure gastrointestinal bleeding.
