胶囊内镜在不明原因消化道出血疾病诊断中的应用

Application of capsule endoscopy to diagnosis of unclear alimentary tract hemorrhage diseases

目的探讨胶囊内镜在不明原因消化道出血中的诊断价值。方法对2008年8月～2011年2月64例不明原因消化道出血患者行胶囊内镜检查结果回顾性分析,评价其疾病诊断率和安全性、全小肠检查完成率及图像质量。结果 64例受检查患者中,成功完成胶囊内镜检查63例,1例因幽门溃疡、梗阻,内镜下送胶囊入十二指肠失败。胶囊在1～4 d内自然排出,胃内通过时间2～349 min,平均56 min;小肠内检查时间35～497 min,平均295 min。患者全小肠检查完成率为74.6%(47/63)。63例患者中,有52例检出病变,阳性率达82.5%(52/63)。所得图像较清晰。结论胶囊内镜安全性好,患者痛苦少,在不明原因消化道出血疾病诊断中有较好的诊断价值。

Objective To discuss the value of capsule endoscopy in the diagnosis of unclear gastrointestinal bleeding.Methods A retrospective analysis of examination results was made among 64 case of unclear gastrointestinal bleeding who underwent capsule endoscopy from August 2008 to February 2011.The diagnosis rate of disease,safety,the completion rate of whole small intestine examination and image quality were evaluated.Results Among the 64 patients,63 ones successfully completed the examination by capsule endoscopy.The capsule was failed to be sent to duodenum in 1 case because of pyloric ulcer and obstruction.The capsule was naturally excreted within 1-4 d.The transit time within the stomach was 2-349 min,and the average time was 56 min.The examination time within the small intestine was 35-497 min with the average time of 295 min.The completion rate of whole small intestine examination was 74.6%（47/63）.Among the 63 cases,pathological changes were detected in 52 ones with the positive rate of 82.5%（52/63）,and the obtained images were quite clear.Conclusion Capsule endoscopy has a great value in the diagnosis of unclear gastrointestinal bleeding with good safety and less pain for patients.
