Impact of Prepackaged Low-Residue Diet on Bowel Preparation for Colonoscopy

Abstract

This meta-analysis aimed to evaluate the impact of prepackaged low-residue diet (PLRD) on bowel preparation for colonoscopy. We searched PubMed, Web of Science, EMBASE, and Cochrane Library databases from inception to August 2020. Randomized controlled trials (RCTs) comparing PLRD with clear liquid diet (CLD) or self-prepared LRD were considered for inclusion. The analysis calculated the odds ratio (OR) for the rate of adequate bowel preparation, patient tolerance, willingness to repeat bowel preparation, tolerability of bowel preparation, and overall adverse effects. Five RCTs published between 2006 and 2019 (N = 561) were included in our meta-analysis. Compared with the traditional CLD or self-prepared LRD, PLRD showed significantly higher rates of adequate bowel preparation (OR, 2.16; 95% confidence interval [CI], 1.18–3.98; p = .01), patient tolerance (OR, 1.99; 95% CI, 1.30–3.07; p = .002), and willingness to repeat the bowel preparation (OR, 1.68; 95% CI, 1.05–2.70; p = .03), with no differences in adverse events (OR, 0.93; 95% CI, 0.59–1.46; p = .75). Prepackaged low-residue diet improved bowel preparation quality, patient tolerance, and willingness to repeat bowel preparations. Importantly, PLRD does not increase the incidence of adverse events. This suggests that it is effective and safe to use PLRD for bowel preparation before colonoscopy.

A Systematic Review of Exercise Therapy for Bowel Preparation

“…However, inadequate bowel preparation is a common problem in gastroenterological practice worldwide. Inadequate bowel cleansing adversely affects various aspects of the colonoscopy procedure, such as prolonging CIT and reducing ADRs (Alvi et al, 2019; Zhang et al, 2021). Poor preparation quality may also increase the risk of procedural-related complications (e.g., perforation, bleeding), as well as increase healthcare costs and patient discomfort due to the need for reexamination (Hotta, 2022; Murphy et al, 2019).…”

An abdominal vibration combined with walking exercise (AVCWE) program for older patients with constipation: Development and feasibility study

“…Adequate bowel preparation is crucial for a successful colonoscopy. [ 10 11 ] However, chronic constipation has been identified as an important independent risk factor for inadequate bowel preparation. [ 12 13 ] Studies have shown that more than 30% of older patients with constipation experience inadequate bowel preparation, leading to a series of adverse consequences, including higher rates of missed adenomas and failed cecal intubation, extended procedure durations, and increased medical costs.…”
