结肠镜检查前肠道清洁效果及其影响因素分析

An Analysis on the Cleaning Status of Intestinal Tract before Coloscopy,and on Its Influence Factors

为调查结肠镜检查前肠道清洁状况,并分析其影响因素,回顾200例接受结肠镜检查的患者资料,统计结肠镜检查前肠道清洁状况,并根据肠道清洁效果分组,分析影响肠道清洁效果的因素。结果显示,200例患者中,肠道清洁程度Ⅰ级61例,Ⅱ级101例,Ⅲ级30例,Ⅳ级8例。肠道清洁合格率为81.0%(162/200)。多因素Logistic回归分析显示,男性、门诊检查、首次肠镜检查、末次口服药物至肠镜检查时间>7h、不良反应是导致结肠镜检查前肠道清洁效果差的独立危险因素,P<0.05。结果表明,结肠镜检查前肠道准备效果受多种因素影响,应重点关注男性、门诊肠道准备、首次肠镜检查、末次口服药物至肠镜检查时间>7h、口服药物后出现不良反应的患者。对于口服药物后出现不良反应者,可考虑分次口服;末次口服药物至肠镜检查时间建议控制在4~7h。

This study was to analyse the cleaning status of intestinal tract before coloscopy,and to investigate its influence factors,reviewed the data of 200 patients who had received coloscopy,based on their cleaning status before coloscopy divided them into four groups:Ⅰgrade,61 cases;Ⅱgrade,101 cases;Ⅲgrade,30 cases,andⅣgrade of 8 cases;and,analysed the factors influencing cleaning status of intestinal tract.As results,the pass ratio of cleaning status was 81.0%(162/200),and Logistic regression analysis showed the independent risk factors inducing clean efficacy worse were male,clinic inspection,first-time of coloscopy,the time from end-time oral administration of drugs to coloscopy>7 hrs.,and unward reaction(P<0.05).Results show that cleaning status before coloscopy is influenced by multi-factors,especially,male patients,clinic intestinal preparation,first-time of coloscopy,the time(from end-time oral administration of drugs to coloscopy)>7 hrs,as well unward reaction onstet after oral administration of drugs,which should be paid attention;for patients suffered from unward reaction it might be to consider oral administration fractionally,and to master the time within 4-7 hrs from end-time oral administration of drugs to coloscopy.
