摘　　要：目的:探讨磁控胶囊内镜的临床诊断价值及影响磁控胶囊内镜操作效率的因素.方法:记录磁控胶囊内镜对胃内各部分结构观察情况,判断磁控胶囊内镜对胃部疾病诊断的可靠性.对比两种饮水方法对胃内清洁度的影响及体位变化对操作时间的影响,观察影响操作的因素.结果:212例患者中贲门、胃底、胃体、胃角、胃窦及幽门的图像采集比例分别为85.8%、89.6%、95.3%、88.2%、93.4%及91.1%,胃窦最容易采集到清晰的图像,为83.0%,胃底最差,只有48.6%.饮水1500 mL组胃内清洁满意度84.6%(44/52),而饮水500mL组仅75.6%(121/160),但两者差异却无统计学意义,提示并不是饮水量越大胃内清洁度就越高,体位变化组操作时间(15.4 min±9.5 min),与单纯操作组(25.1 min±7.4 min)相比操作时间明显缩短(P<0.05).结论:磁控胶囊内镜检查胃部疾病安全可靠,操作前饮水500 mL便可以得到较满意的胃内清洁度,如果配合患者的体位变化,有助于缩短操作时间.AIM：To investigate the reliability of magnetically guided capsule endoscopy（MGCE） and the factors influencing its performance.METHODS：The reliability of MGCE in diagnosing gastric diseases was judged by recording the pictures for different parts of the stomach.Factors influencing MGCE operation was assessed by comparing the cleaning degree of the stomach between two kinds of drinking way and the effect of body position change on operation time.RESULTS：The proportions of cardia,gastric fundus,gastric body,gastric angle,gastric antrum,and pylorus pictures taken in 212 patients were 85.8%,89.6%,95.3%,88.2%,93.4%and 91.1%,respectively.The rate of satisfactory pictures of the gastric antrum was highest（83.0%）,while that of the gastric fundus was lowest（48.6%）.The rates of satisfaction in patients drinking 1500 mL water and 500 mL water were84.6%（44/52） and 75.6%（121/160）,respectively,showing no statistical difference.The mean operative time（15.4 min ± 9.5 min） in the body position change group was significantly shorter than that（25.1 min ± 7.4 min） in the simple operating group（P 〈 0.05）.CONCLUSION：MGCE is reliable for detecting gastric diseases.Drinking 500 mL water before operation is associated with satisfactory cleanliness degree of the stomach.The mean operation time can be shortened by changing the patient’s body position.
