NaviCam遥控胶囊内镜临床应用初探（含视频）

Application of NaviCam magnetic-controlled capsule endoscopy system （ with video）

目的探讨NaviCam遥控胶囊内镜在上消化道检查中的应用价值。方法纳入39例健康志愿者，使用NaviCam遥控胶囊内镜完成胃部主动式检查，评价其安全性、受检者舒适度及对食管、胃黏膜的观察情况。结果在食管齿状线、贲门、胃底、胃体、胃角、胃窦、幽门部主动观察能观察到75％以上黏膜者分别为19例（48．71％）、37例（94．87％）、25例（64．10％）、30例（76．92％）、39例（100．00％）、39例（100．00％）、39例（100．00％），以上部位平均主动观察时间分别为1．5min、3．0min、8．0min、17．0min、3．0min、3．0min、5．0min。主动控制胶囊进入十二指肠者25例（64．10％），平均所需时间8．0min；7例主动控制进入十二指肠失败；7例发生胶囊内镜非自主进入小肠，其中1例未能完成1次有效主动观察，胶囊完成1次主动有效观察率为97．43％（38／39）。检查过程中仅1例出现异物感。受检者均于检查后7d内排出胶囊。结论NaviCam遥控胶囊内镜行上消化道检查安全可行，效果好，且患者舒适，无交叉感染风险，具有良好的临床应用前景。

Objective To investigate the clinical significance of NaviCam magnetic-controlled capsule endoscopy （NMCE） system in the examination of upper gastrointestinal tract. Methods A total of 39 healthy volunteers were enrolled in the present study. NMCE system was used to examine upper gastrointestinal tract. The safety, gastric preparation, visualization and comfort of the subjects were evaluated. Results Visualization of the Z-line, gastric cardia, fundus, body, angulus, antrum and pylorus was subjectively assessed as more than 75% mueosa in 19 （48.71%）, 37 （ 94. 87% ）, 25 （ 64. 10% ）, 30 （ 76. 92% ）, 39 （ 100.00% ） ,39 （ 100.00% ）, and 39 （ 100. 00% ）, respectively. The observation time was 1.5,3.0,8.0, 17. 0,3.0,3.0,5.0 min respectively. The capsule was driven into duodenum positively in 25 （64. 10% ）. Seven subjects went into small bowel without control. The one-time visualization efficacy was 97. 43% （38/39）. Only one subject felt foreign body sensation. All subjects extracted the capsule within 7 days. Conclusion Our study provides a preliminary assessment of the NMCE on its feasibility and safety. It is comfortable with no chance of cross-infection. NMCE system is a useful tool for upper GI examination and will have a good future.
