单气囊小肠镜在诊断胶囊内镜检查阴性的可疑小肠疾病患者中的应用价值

目的：探讨单气囊小肠镜（single-balloonenteroscop，SBE）在胶囊内镜检查阴性的可疑小肠疾病患者中的应用价值。方法：选取在我院行胶囊内镜检查无异常发现，后行单气囊小肠镜检查的可疑小肠疾病患者24例，分析后者对胶囊内镜检查阴性可疑小肠疾病患者的阳性发现率和病因的分布特点。结果：24例行SBE检查者有22例（91．7％）获得成功，2例失败，10例被检出阳性病变，其中间质瘤5例，小肠息肉2例，过敏性紫癜1例，血管畸形2例，SBE对胶囊内镜检查阴性的患者小肠疾病的再检出率为41．7％。结论：胶囊内镜和SBE在小肠疾病的诊断上有着各自的优缺点，对于胶囊内镜检查阴性的可疑小肠疾病患者进一步行SBE检查有助于确诊。

The Application Value of Single-balloon Endoscopy in Small Intestinal Diseases Having no Diagnosis under Capsule Endoscopy

Objoetive： To study the application value of single-balloon endoscopy （SBE） in small intestinal diseases having no diagnosis under capsule endoscopy. Methods： 24 patients with suspected small intestinal diseases having no diagnosis under capsule endoscopy, and were accepted examination by SBE. The etiologic feature and significance of SBE was explored in these patients being positive. Results： SBE proceeded successfully in 22 （91.7%） of total 24 patients, 10 of them were diagnosed （41.7%）, including stromal tumor （5）, intestinal polys （2）, allergic purpura （1）, vascular malformation （2）. Conclusion： SBE and capsule endoscopy have their respective advantages and disadvantages, it is necessary to accept examination by SBE for patients who had no diagnosis under capsule endoscopy.
