胶囊内镜对小肠疾病的诊断价值

Diagnosis Value of Capsule Endoscopy in Intestinal Diseases

目的 研究M2A胶囊内镜对胃肠道特别是小肠病变的检出率及病变类型 ,探讨胶囊内镜对小肠疾病的诊断价值。方法 运用M2A胶囊内镜对 3 7例疑诊小肠疾病和体检者进行检查。结果 疑诊小肠疾病组发现小肠病变 18处 ,包括克罗恩病、小肠寄生虫、回肠淋巴瘤、回肠Mechel憩室、小肠海绵状血管瘤、小肠息肉样病变、小肠糜烂、回肠末端炎、十二指肠炎或溃疡、十二指肠囊肿 ,病变检出率为 81 8% ,诊断阳性率为 68 2 % (15 /2 2 ) ;高于体检组。两组病例M2A胶囊内镜在消化道不同部位的运行时间比较无显著差异 ,胶囊内镜平均工作时间 ,获取照片数量无显著差异 ,胶囊内镜图片质量佳 ,病人耐受性好。结论 胶囊内镜对疑诊小肠疾病的病变检出率较高 ,而且安全无创 ,可以作为小肠疾病检查的首选方法。

Objective To investigate the detective rate of M2A capsule endoscopy for gastrointestinal diseases, especially small intestinal diseases and its categories of pathological changes, so as to explore its diagnosis value in small intestinal diseases. Methods Case group with suspicious small intestinal diseases and healthy group were examined by M2A capsule endoscopy in total 37 individuals.Results There were 18 locations of pathological changes in small intestine found in case group, including Crohns disease, small intestinal parasite, ileum leukoma, Mechel diverticula of ileum, small intestine cavernous hemangioma, polyposis shape pathological change of small intestine, erosion, terminal ileitis, duodenitis or ulcer, duodenum cyst. The detective rate in this group was 81 8%, and the positive rate was 68 2%, which were both higher than that in healthy group. Among these two groups, no significant difference was found in travel time of capsule endoscopy in different region of alimentary tract and the photo quantity. The quality of the photos was good, and the patients had a well tolerance. Conclusions Capsule endoscopy can be regarded as a preferred method in diagnosis of small intestinal diseases, due to its high detective rate and non invasion.
