胶囊内镜对不明原因消化道出血的诊断价值

Evaluating the value of capsule endoscopy in diagnosing obscure gastrointestinal bleeding

目的 比较胶囊内镜与传统小肠检查方法对不明原因消化道出血的诊断价值。方法 总结分析 6 7例胃镜、肠镜检查阴性的消化道出血患者中消化道钡餐、肠系膜动脉造影、推进式小肠镜、胶囊内镜及剖腹探查包括手术中肠镜结果。结果 不明原因消化道出血上、中消化道钡餐检查检出率为 1 7 6 % ,诊断率为 1 3 8% ;肠系膜动脉造影检查检出率和诊断率均为 1 3 4 % ;推进式小肠镜检查检出率、诊断率为 32 % ;剖腹探查及术中肠镜检出率和诊断率均为 83 3% ;胶囊内镜检查检出率为80 6 % ,诊断率为 6 7 7%结论 胶囊内镜检查对于不明原因消化道出血具有较高的检出率和诊断率 。

Objective To compare the detect abilities of obscure gastrointestinal bleeding by capsule endoscopies and conventional intestinal examinations.Methods To analyze the results of gastrointestinal barium meal examination, arteriography of superior mesenteric artery, push enteroscopy, capsule endoscopy, and enteroscopy during exploratory laparotomy in 67 patients with obscure gastrointestinal bleeding.Results Detectable rates of gastrointestinal barium meal examination, arteriography of superior mesenteric artery, push enteroscopy, capsule endoscopy, and enteroscopy during exploratory laparotomy are 17 6%, 13 4%, 32 0%, 80 6%, and 83 3% respectively, and their diagnostic rates are 13 8%, 13 4%, 32 0%, 67 7%, and 83 3% respectively. Conclusion Capsule endoscopy is superior to conventional methods of intestinal examinations having high detectable and diagnostic rates in obscure gastrointestinal bleeding; it should be the first choice in diagnosing obscure gastrointestinal bleeding.
