摘　　要：目的评价单气囊小肠镜对于不明原因消化道出血的诊断价值。方法应用单气囊小肠镜对72例不明原因消化道出血患者进行78次检查，其中经口进镜40次，经肛进镜38次。记录检查时间、深度、阳性率。结果40次单气囊小肠镜经口进镜检查用时15～110min，平均60min，插入深度为屈氏韧带远端30～240cm，平均195cm；38例次单气囊小肠镜经肛进镜检查用时30～120min，平均75min，插入深度为回盲瓣近端50—200cm，平均160em；62．5％的患者发现足以解释患者出血原因的小肠病变。结论单气囊小肠镜对于不明原因消化道出血是安全、有效的。Objective To investigate the diagnostic value of single balloon enteroscopy （SBE） for obscure gastrointestinal bleeding. Methods A total of 78 SBE procedures was conducted on 72 patients with obscure gastrointestinal bleeding, with 40 via oral route and 38 via anal route. The procedure time, insertion depth and rate of positive finding were recorded. Results For 40 SBE procedures performed via oral route, the mean procedure time was 60 minutes （ 15-110 minutes）, and the mean insertion depth was 195 cm at the distal end of Trentz ligament （30-240 cm）. For 38 SBE procedures performed via anus, the mean procedure time was 75 minuets （30-120 minutes）, and the mean insertion depth was 160 cm at the proximal end of ileocecal valve （50-200 cm ）. The whole diagnostic yield of obscure gastrointestinal bleeding was 62. 5%. Conclusion SBE is a safe and useful tool for the diagnosis of obscure gastrointestinal bleeding.
