结肠镜检查两种饮食准备方法对肠道准备质量的比较

 目的 比较两种饮食准备方法对肠道准备质量的影响。方法 选取2018年1-12月在武警北京总队医院行结肠镜检查的门诊患者150例,随机分为预包装组和自备组,每组75例,预包装组检查前1 d三餐摄入预包装食物,自备组检查前1 d按照常规摄入自备低渣饮食,两组清肠液均采用复方聚乙二醇电解质散4 L,于检查当日晨4:00口服。观察两组息肉发现率、首次排便时间、排便次数、进镜时间、退镜时间。结果 预包装组息肉发现率为37.3%,自备组息肉发现率为32.0%,两组差异无统计学意义(P＞0.05);预包装组第1次排便时间明显少于自备组,两组差异有统计学意义(P＜0.05);预包装组排便次数少于自备组,两组差异有统计学意义(P＜0.05);预包装组进镜时间少于自备组,两组差异有统计学意义(P＜0.05)。结论 预包装饮食用于结肠镜检查饮食准备可以缩短首次排便时间,减少排便次数,缩短进镜时间,提高肠道准备质量。

A comparative study of effect of prepackaged diet and self made low-residue diet on quality of bowel preparation

Objective To compare the effect of two different dietary regimens on quality of bowel preparation among patients intended for colonoscopy.Methods In this study, 150 patients who underwent colonoscopy were selected as subjects, who were randomly divided into two groups: the pre-packaged group and the self-provided group, with 75 cases in each. Single-center, single-blind, prospective and controlled studies were conducted. The patients of the pre-packaged group(group of pre-packaged diet) took pre-packaged food for three meals a day before the examination, while the patients of the self-provided group(the low-residue diet group)took the low-residue diet provided by themselves one day before the examination. The intestine-rinsing fluid used by both groups was 3L sulfate-free polyethylene glycol electrolyte powder and patients took it orally at 4:00 a.m. on the day of examination.Results The detection rate of polypus was 37.3% for the pre-packaged group and 32.0% for the self-provided group. There was no significant difference between the two groups (P>0.05).In terms of the time for the first defecation, the pre-packaged group scored 46.25±28.23, which was significantly lower than that of the self-provided group(65.34±34.54)(P<0.05). In terms of insertion time, the pre-packaged group scored (5.35±1.63),which was lower than that of the self-provided group (8.24±2.26)(P<0.05).Conclusions The prepackaged diet can shorten the time interval before the first defecation, reduce the frequency of defecation,shorten the insertion time of, and improve the quality of colonoscopy.
