Objective To analyze the reasons for failure in capsule endoscopy and to suggest countermeasures so as to improve the successful rate of the procedure. Methods We made a retrospective analysis on 64 cases of capsule endoscopy in Tongji Hospital from May 2008 to May 2012. Results The completion rate of the small intestines was 95% in 64 cases of capsule endoscopy. The endoscope could not pass through the esophagus of 1 patient (1. 5%) due to esophageal restenosis after e-sophageal dilatation;it was incarcerated in the small intestine of 1 patientd. 5%) ;it was retained in the stomach of 10 patients (15. 6%) ;it could not pass through the ileocecal valve of 1 patientd( 1.5%)before battery depletion. Besides,image was fuzzy in 6 cases9. 4 %)because of poor bowel preparation. Conclusion It is suggested that careful preoperative assessment and reasonable selection of patients,full bowel preparation, real-time monitoring and guidance for patients can improve the successful rate and diagnostic rate of capsule endoscopy.%目的 探讨胶囊内镜检查失败原因及对策,提高胶囊内镜检查的成功率.方法 回顾性分析同济医院2008年5月至2012年5月64例胶囊内镜检查病例.结果 64例胶囊内镜检查全小肠完成率为95％.食管扩张术后食管再狭窄胶囊内镜不能通过食管1例(1.5％),胶囊内镜小肠内嵌顿1例(1.5％),胶囊内镜胃内排出延迟10例(15.6％),电池耗竭前胶囊内镜没有通过回盲瓣1例(1.5％),肠道准备不佳致图像紊乱模糊6例(9.4％).结论 术前认真评估,合理选择患者,充分肠道准备,实时监测指导患者,可以提高胶囊内镜检查的成功率和诊断率.
