Abstract:

Objective To understand the status of the bowel preparation quality of outpatients with colonoscopy. To analyze the effect of interval time from the completion of bowel preparation to the start of colonoscopy on the quality of bowel preparation. Methods Demographic and clinical data of outpatients undergoing colonoscopy at digestive endoscopy center of 3 general hospitals in Fuzhou from April 2019 to September 2019 were collected.Chi-square test was used to screen the factors with statistical significance on the bowel preparation quality(P<0.10). After statistical method of propensity value matching was used to eliminate the confounding factors,the differences in bowel preparation quality between different interval groups(divided into(2,3] h、(3,4] h、(4,5] h、(5,6] h、(6,7] h、(7,8] h、(8,∞) h) were compared by variance analysis. Results A total of 401 patients were enrolled in the study. After matching of 401 samples with propensity value matching,316 new samples were generated and the influence of confounding factors was excluded by test. Compared the data with analysis of variance,the quality of bowel preparation was different in different interval time groups.The quality of bowel preparation in group of(2,3] h was significantly better than groups of(4,5] h and(6,7] h. The quality of bowel preparation in group of(3,4] h was significantly greater than(6,7] h. There was no significant difference between 2 groups of(2,3] h and(3,4] h. There was no significant difference between any 2 groups in(4,5] h,(6,7] h,(7,8] h,(8,∞) h. Conclusion The quality of bowel preparation can be maintained at an optimal state of cleanliness within 2~4 hours between the completion of bowel preparation and the start of colonoscopy.

摘要:

目的 了解结肠镜检查患者肠道准备现状并分析其影响因素,评价肠道准备完成至结肠镜检查开始的间隔时间对肠道准备质量的影响。 方法 收集2019年4月—9月在福州市3所三级甲等医院消化内镜中心行结肠镜检查门诊患者的人口统计学与临床资料。采用卡方检验筛选对肠道准备质量影响显著的因素(P<0.10),应用倾向值匹配分析法消除混杂因素后,对比间隔时间(2,3] h、(3,4] h、(4,5] h、(5,6] h、(6,7] h、(7,8] h、(8,∞) h组的肠道准备质量差异。 结果 共有401例患者纳入研究,经匹配新生成316组样本数据,并检验证实已排除混杂因素影响。方差分析得出:不同间隔时间组之间的肠道准备质量存在差异,间隔(2,3] h肠道准备质量显著优于(4,5] h、(6,7] h,间隔(3,4] h肠道准备质量显著优于(6,7] h,(2,3] h与(3,4] h两组之间无显著差异,(4,5] h、(6,7] h、(7,8] h、(8,∞) h任意两组之间无显著差异。 结论 肠道准备完成至开始结肠镜检查间隔时间在2~4 h内,肠道准备质量可以保持在最佳清洁状态。
