胶囊内镜在小肠疾病中的临床诊断价值

目的：探讨胶囊内镜在小肠疾病中的诊断价值.方法：分析2009年9月-2012年5月114例行胶囊内镜检查患者的临床资料.结果：113例患者完成检查.胶囊内镜回盲瓣通过率为90.3%（102/113例）;胃内运行时间3～187 min,平均（55.6±26.0）min;小肠内运行时间为24～640 min,平均（303±106） min;胶囊平均排出体外的时间为9～96 h,平均（29±10）h.63例发现小肠病变（55.7%）,病变分别为非特异性炎症24例,血管畸形13例,小肠克罗恩病12例,小肠息肉7例,小肠肿瘤3例,小肠钩虫2例,小肠憩室1例.消化道出血患者小肠病因检出率最高,为80.8%（42/52例）,其次是腹痛45.2%（14/31例）,消瘦33.3%（1/3例）,腹泻20.0%（1/5例）,腹胀14.3%（1/7例）.结论：胶囊内镜对小肠疾病有较高的诊断价值.

Diagnostic value of capsule endoscopy in diagnosing small intestinal diseases

Objective：To investigate the diagnostic value of capsule endoscopy for small intestine diseases. Methods;The clinical data of 114 patients who underwent capsule endoscopy between September 2009 and May 2012 were retrospectively analyzed. Results. The inspection success rate was 90.3% （102/113 cases）. The average run： ning time of the capsule in stomach ranged from 3 to 187 minutes with average time of （55.6 ±26.0）minutes. The running time of capsule in the small intestine ranged from 24 to 640 minutes with average of （303 4-106） minutes. The time of ejection of the capsule ranged from 9 to 96 hours with an average of （294-10） hours. Small intestinal mucosa lesions were found in 63 among 113 patients （55.7%）, among them 24 patients showed non- specific inflammation,13 patients were found to have vascular malformation, 12 patients with Crohn＇s disease, 7 patients with polyps, 3 patients with tumor, 2 patients with ancylostomiasis, and 1 patient with diverticulum. The diagnostic positive rate was 80.8 % （42/52 cases）and it was highest in patients with bleeding. It was 45.2 % （14/ 31 cases） in abdominal pain group, 33.3%（1/3 cases） in weight reduction group, 20. 0%（1/5 cases） in diarrhea group, and 14.3 % （1/7 cases） in abdominal distension group. Conclusions.. Capsule endoscopy has a high value in diagnosing small intestinal diseases.
