单气囊小肠镜在小肠疾病诊断中的应用

目的评价单气囊小肠镜（SBE）在小肠疾病诊断中的安全性、检查范围及临床价值。方法对2009年6月至9月间行SBE检查的疑有小肠疾病患者的临床资料进行回顾性分析，总结检查完成情况、操作时间以及并发症发生情况等。结果30例患者共行35例次SBE检查。单纯经口检查15例；单纯经肛检查10例；经口＋经肛检查5例，均完成对接检查。共26例明确诊断，疾病检出率为86．7％（26／30）。经口进镜检查平均用时49．7min，经肛进镜检查平均用时48．6min。所有患者检查过程中生命体征处于安全范围，无心脑血管并发症发生，无剧烈腹痛及出血、穿孔等并发症出现。结论SBE是一种安全、可靠的检查手段，用于诊断小肠疾病具有较好的临床价值。

Single balloon enteroscopy for diagnosis of small bowel diseases

Objective To evaluate the safety, indications and clinical efficacy of single balloon enteroscopy (SBE) for diagnosis of small bowel diseases. Methods Data of 30 patients (21 males and 9 females) with suspected small bowel diseases, who underwent SBE from June to September 2009, were retrospectively studied to analyze the access, procedure time and complications of SBE. Results A total of 35 SBE procedures were performed on 30 patients. Procedures were performed via oral, anal and the combined routes in 15, 10 and 5 cases, respectively, and definite diagnosis was made in26 cases (86. 7% ). The average access times via oral and anal routes were 49.7 min and 48. 6 min, respectively. Patietns showed normal vital signs during the procedures. No such procedure-related complications as cadiovascular events, severe abdominal pain, bleeding or perforation, were observed. Conclusion SBE is a safe and reliable diagnostic modality of high clinical value for small bowel diseases.
