摘　　要：目的评价双气囊小肠镜在小肠出血诊断中的应用价值。方法对该院2005年4月～2008年12月期间拟诊为小肠出血的患者22例行双气囊电子小肠镜检查,检查前所有患者均经常规电子胃镜、电子结肠镜等相关检查未发现可解释临床症状的确切病灶,9例患者经口进镜检查,5例患者经肛进镜检查,8例患者先后分别进行了经口和经肛进镜检查,对所得检查结果进行统计学和临床分析。结果22例患者21例发现异常,19例发现了能明确解释小肠出血的病因,检出率为95.45%(21/22),诊断率为86.36%(19/22)。其中小肠血管畸形的6例,炎症性肠病6例,小肠溃疡的3例,小肠寄生虫感染2例,小肠肿瘤的1例,小肠多发性憩室并出血的1例。结论双气囊小肠镜能安全迅速地检查全小肠,具有直视、可控性好、能活检及进行镜下治疗等优点,为小肠出血患者提供了全新的检查手段。[ Objective ] To investigate the diagnostic value of double-balloon enteroscopy in small intestinal bleeding. [Methods] From April 2005 to December 2008, 22 patients with suspected small intestinal bleeding in our hospital underwent double-balloon enteroscopy. In every patient who was inspected by the conventional electron gastroscopy and colonoscopy and other related inspection, positive lesion was not found before under-going double-balloon enteroscopy. Antegrade and retrograde approaches were performed in 9 and 5 patients respectively, and 8 patients had a combination of both routes. The results were analyzed statistically and clinically. [Results] Abnormality in small bowel was detected in 21 out of 22 patients（95.45%）, but exact lesions for small intestinal bleeding were only found in 19 out of 22 patients （86.36%）. That is to say the detected rate was 95.45% and the diagnostic yield was 86.36%. These disorders included vascular malformation of small intestine （n=6）, inflammatory bowel diseases （n=6）, small bowel ulcer （n=3）, small intestinal parasitic infections （n=2）, small bowel tumor （n=1）, and small intestine multiple diverticula and hemorrhage （n=1）. [ Conclusion] The double-baUoon push enteroscopy has the advantage of allowing direct visualization, taking biopsy specimens easily and treating lesions directly, and it is a new diagnostic method for small intestinal bleeding.
