胶囊内镜在不明原因消化道出血中的临床应用

目的探讨胶囊内镜在不明原因消化道出血中的诊断价值、耐受性、并发症。方法对20例不明原因消化道出血患者行OMOM胶囊内镜检查。结果15例胶囊内镜下发现异常,12例明确为出血病灶,诊断率为60%（12/20）,包括克罗恩病5例,间质瘤4例,晚期肿瘤1例,新鲜出血1例,血管瘤1例。20例受检者均耐受良好,2例出现了胶囊滞留。结论胶囊内镜对不明原因消化道出血有较高的诊断率,易耐受,胶囊滞留是其主要并发症,易发生于克罗恩病患者。

The application of the capsule endoscopy in obscure gastrointestinal bleeding

Objective To investigate the diagnostic value, tolerance and complication of the capsule endoscopy in obscure gastrointestinal bleeding （OGB）. Methods Twenty patients with OGB were examined by OMOM capsule endoscopy. Results Fifteen patients were found abnormal under OMOM capsule endoscopy, 12 patients were identified the focus of bleeding. The diagnostic rate was 60% , including 5 Crohn＇ s disease patients, 4 interstitialoma patients, 1 angiodysplasia patient, 1 fresh bleeding patient and 1 tumour patient. The 20 patients were well tolerated with the capsule endoscopy, and delayed excretion of capsule endoscopy occurred in only 2 patients. Conclusion The capsule endoscopy is safe and well tolerated with a high diagnostic rate in diagnosis of OGB. Delayed excretion of the capsule is the main complication, which is prone to occur in patients with Crohn＇ s disease.
