消化道出血患者的胶囊内镜检查

Capsule Endoscopy in Diagnosing Gastrointestinal Bleeding

目的评价胶囊内镜在消化道出血患者中的诊断价值。方法对53例不明原因消化道出血患者、22例因心肺脑功能不全无法耐受常规胃肠镜检查的消化道出血患者,采用M2A胶囊内镜进行胃肠道检查。结果75例中有74例(98.6%)完成检查,发现消化道病变64例,检出率86.5%,包括胃部病变4例,小肠病变58例,结肠病变2例;41例(55.4%)检出出血病因。22例在胶囊内镜检查后,采用双气囊小肠镜对胶囊内镜检查结果予以验证,发现18例的病因诊断和定位相符。结论胶囊内镜对消化道出血,尤其是小肠源性出血具有较高的诊断价值。

Objective To evaluate the application of capsule endoscopy （CE） in diagnosing gastrointestinal （GI） bleeding. Methods Fifty-three patients with obscure GI bleeding and 22 patients with GI bleeding, who could not undergo the traditional endoscopies because of the organs dysfunction, were enrolled to this study and underwent capsule endoscopies. Capsule endoscopies were performed with GIVEN M2A video capsule system. Results Among the 75 patients, 74 completed the CE successfully which disclosed abnormal digestive tract findings in 64 out of 74 patients （86.5%）. The positive findings included stomach lesions in 4, intestinal lesions in 58 and colon lesions in 2 patients. Forty-one of 74 patients had significant pathological findings which could explain their clinical symptoms, so the diagnostic yield was 55.4%. Double-balloon enteroscopies were done in 22 patients after CE. In 18 patients, the diagnosis and pathological sites founded by double-balloon enteroscopy were similar to those by CE. Conclusion CE is an efficient tool in the diagnosis of GI bleeding, especially of the intestinal bleeding.
