目的 比较胶囊内镜阴性的潜在小肠出血患者发生再出血事件后,重复胶囊内镜或小肠镜的诊断价值.方法 回顾性分析郑州大学第一附属医院2011年1月至2013年12月胃镜、结肠镜、腹部CT及胶囊内镜检查均阴性的潜在小肠出血患者,此类患者再出血后,胶囊内镜与小肠镜的诊断价值.结果 共纳入胃镜、结肠镜及腹部CT检查阴性并顺利完成胶囊内镜的潜在小肠出血患者215例,其中胶囊内镜阴性并再出血患者41例,重复胶囊内镜检查19例,小肠镜检查22例,重复胶囊内镜检出率高于小肠镜检出率(73.68% vs 36.36%,P=0.017).结论 胶囊内镜阴性的潜在小肠出血患者再出血重复胶囊内镜检出率高于小肠镜检出率.%Objective To compare the diagnostic value of capsule endoscopy or enteroscopy for re-bleeding in poten-tial small-bowel bleeding patients who had negative findings in capsule endoscopy.Methods The patients with potential small-bowel bleeding whose endoscopy,colonoscopy,abdominal CT,and capsule endoscopy were all negative were col-lected in the First Affiliated Hospital of Zhengzhou University from Jan. 2011 to Dec. 2013,the diagnostic value of sec-ond-look capsule endoscopy and enteroscopy after re-bleeding occurred in such patients were analyzed.Results Two hundred and fifteen potential small-bowel bleeding patients whose endoscopy,colonoscopy and abdominal CT examination were negative were collected and successfully completed capsule endoscopy,among which 41 patients had negative findings in capsule endoscopy and re-bleeding,19 patients with second-look capsule endoscopy and 22 patients with enteroscopy. The positive rate of second-look capsule endoscopy was higher than that of balloon enteroscopy(73.68% vs 36.36%,P=0.017).Conclusion The detection rate of second-look capsule endoscopy is higher than enteroscopy in potential small-bowel bleeding patients with capsule endoscopy negative and re-bleeding.
