目的：评估单气囊小肠镜在小肠肿瘤诊疗中的临床应用价值。方法：回顾性分析我院内镜中心2009年2月至2014年12月期间进行单气囊小肠镜检查的354例患者的临床资料。结果：共有354例患者进行了532例次（378次经口,154次经肛）小肠镜检查,总诊断率为72.9%（258/354）,其中共发现小肠肿瘤46例（17.8%,46/258）。临床表现为不明原因消化道出血的159例患者中发现小肠肿瘤22例（13.8%,22/159）,表现为慢性腹痛的118例患者中发现小肠肿瘤15例（12.7%,15/118）。4例患者行小肠镜下腺瘤及息肉切除（共计97枚）,3例患者行小肠狭窄扩张术。本研究未观察到严重并发症。结论：单气囊小肠镜在小肠肿瘤诊断中具有重要地位,且镜下治疗安全有效。
