预包装低渣饮食与常规饮食在结肠镜检查前肠道准备中的应用效果比较

Comparison of efficacy between prepackaged low-residue diet and conventional diet for bowel preparation before colonoscopy

目的评价预包装低渣饮食与常规饮食在结肠镜检查前肠道准备中的应用效果。方法检索Cochrane Library、Ovid、Pub Med、Web of Science、中国知网、中国生物医学文献数据库、维普数据库、万方数据库,纳入有关预包装低渣饮食与常规饮食应用于结肠镜检查前肠道准备的随机对照试验,筛选文献并评价文献质量后,应用Rev Man 5. 3软件进行Meta分析。结果纳入文献5篇,共512例研究对象。Meta分析结果显示,预包装低渣饮食组的肠道清洁有效率、依从饮食准备的患者比例、愿意再次接受肠道准备的患者比例均高于常规饮食组(均P <0. 05);两组不良反应发生率比较,差异无统计学意义(P> 0. 05)。结论预包装低渣饮食有助于患者改善肠道清洁效果及饮食准备依从性,并且不会增加不良反应发生率。

Objective To evaluate the efficacy between prepackaged low-residue diet and conventional diet for bowel preparation before colonoscope.Methods The databases of computer retrieval included Cochrane Library,Ovid,Pub Med,Web of Science,CNKI,CBM,VIP and Wanfang Databases.The randomized controlled trials about prepackaged low-residue diet and conventional diet applied to bowel preparation before colonoscopy were collected.After literature screening and quality assessment,a Meta-analysis was conducted using Rev Man5.3software.Results Five trials consisting of512subjects were enrolled.The results of Meta-analysis showed that prepackaged low-residue diet obtained higher bowel cleaning rate and higher proportion of cases with dietary preparation compliance or the willingness to choose same preparation again compared to the conventional diet group(all P0.05);there was no statistically significant difference in the incidence rate of adverse reactions between the two groups(P0.05).Conclusion The prepackaged low-residue diet is helpful to improve efficacy of intestinal cleaning and patients'compliance for diet preparation,and does not increase the incidence rate of adverse reactions.
