摘　　要：目的研究蹲厕行为对胶囊内镜检查胃转运时间(gastric transit time,GTT)和全小肠检查率(complete examination rate of small bowel,CER)的影响。方法随机纳入2019年1-12月于重庆医科大学附属第二医院行胶囊内镜检查的患者122例,采用随机数字表法将其分为试验组63例和对照组59例,试验组即吞服胶囊后随时可以蹲厕,对照组如需如厕采取坐便。比较2组患者GTT、小肠转运时间、CER和诊断率的区别。结果试验组和对照组患者在性别、年龄、住院情况等方面差异无统计学意义。试验组患者CER显著高于对照组(92.06%vs 79.66%),差异有统计学意义(P=0.048)。试验组患者中位GTT显著少于对照组(26.7 vs 45.6 min),差异有统计学意义(P=0.027)。两组患者在小肠转运时间和诊断率上差异无统计学意义。结论行胶囊内镜检查患者采用蹲厕行为能减少胶囊在胃内转运时间,增加全小肠检查率。Objective To study the effect of squatting toilet behavior on gastric transport time(GTT)and complete examination rate of small bowel(CER)during capsule endoscopy.Methods A total of 122 patients who underwent capsule endoscopy at the Second Affiliated Hospital of Chongqing Medical University from January to December 2019 were recruited and randomly divided into test group(n=63)and control group(n=59).The patients of the test group were asked to take squatting posture for toileting after swallowing the capsule,while those of the control group were asked to take sitting in defecation if needed.GTT,small bowel transit time(SBTT),CER and diagnostic yield(DY)were compared between the 2 groups.Results There were no significant differences in gender,age and conditions during hospitalization between the test group and the control group.The test group obtained obviously higher CER(92.06%vs 79.66%,P=0.048)and shorter GTT(26.7 vs 45.6 min,P=0.027)when compared with the control group.No statistical differences were seen in SBTT and DY between the 2 groups.Conclusion Squatting posture for toileting of patients accepted capsule endoscopy can reduce the transit time of capsules in the stomach and increase the CER.
