OMOM胶囊内镜检查疑诊小肠出血37例分析

Analysis of outcome in 37 patients suspected bleeding of small intestine undergoing capsule endoscopy

目的分析评价OMOM胶囊内镜对疑诊小肠出血的诊断价值。方法对37例考虑小肠出血的胶囊内镜检查结果进行统计分析。结果37例患者均顺利完成检查,平均通过小肠时间为284min,胶囊内镜检查有效时间内4例未通过回盲瓣。共检出小肠病变33例,结合临床明确小肠出血部位及病因31例,诊断率为83.78%。病因包括:毛细血管扩张表现4例,小肠静脉血管畸形11例,小肠多发溃疡3例,小肠黏膜炎性糜烂导致出血7例,小肠肿瘤4例,克罗恩病2例。结论患者对胶囊内镜耐受性好,胶囊内镜是小肠出血的安全、有效、舒适的检查手段,在小肠出血诊断中有着特殊优势。

Objective To assess the value of capsule endoscopy in diagnosis of obscure bleeding of small intestinal origin. Methods We evaluated the outcome in patients with obscure small intestinal bleeding undergoing capsule endoscopy. Results 37 patients were successfully examined. The mean time for capsule getting into the small intestinal duct was 284 minutes, with capsule in 4 patients failing to get through ileoceeal valve in the working time of capsule. Mueosa lesion were found in 33 patients and bleeding sites were identified in 31 patients, with the diagnosis rate being 83.73%. The etiology included： telangiectasis in 4 patients, veinous malformation in 11, multiple sites ulcer in 3, ileac erosion leading to bleeding in 7, small intestine tuma in 4, Crohn ＇ s disease in 2. Conclusion Capsule endoscopy is a safe, effective and well-tolerated modality in visualizing the small intestine in patients with undermined bleeding origin, reflecting the advantage in diagnosis for small intestinal bleeding.
