双气囊内镜对不明原因消化道出血病因的诊断价值

Double Balloon Endoscopy for Diagnosis of Obscure Gastrointestinal Bleeding

目的探讨双气囊内镜(DBE)在不明原因消化道出血(OGIB)病因诊断中的临床应用价值。方法对31例解黑便或血便且经过多次胃镜、肠镜检查不能确定出血病灶等怀疑为小肠出血者患进行双气囊内镜检查,分析其病因诊断率及其安全性。结果 31例行双气囊内镜检查,经口检查20例,经肛检查5例,经口+经肛6例,发现病灶25例,未发现病灶6例,病因诊断率80.6%(25/31)。未见操作相关严重不良反应和并发症。结论双气囊内镜检查安全、可靠,对不明原因消化道出血病因诊断率显著提高,是一种有效的检查手段。

Objective To evaluate the clinical value of double-balloon endoscopy（DBE） in the diagnosis of obscure gastrointestinal bleeding（OGIB）.Methods The DBE was performed in 31 patients with melena or bloody stools who had suspected small intestinal bleeding diagnosed by endoscopy and colonoscopy.The etiological diagnosis rate and the security were analyzed in all patients.Results Among the 31 patients,DBE was performed via oral route in 20,via anus route in 5,and via both oral route and anus route in 6.The DBE showed focus in 25 patients（80.6%）.No operation-related serious adverse reactions and complications occurred in all patients.Conclusion The DBE is safe,reliable and effective for the diagnosis of OGIB.
