Summary
Brief summary (as posted)
This randomized controlled trial aims to evaluate the effects of different ratios of electrolyte beverage and water combined with polyethylene glycol (PEG) on bowel preparation quality before colonoscopy. Participants undergoing elective colonoscopy will be randomly assigned to one of three bowel preparation regimens: PEG prepared with water only, PEG prepared with a low ratio of electrolyte beverage and water, or PEG prepared with a medium ratio of electrolyte beverage and water. The primary outcome is adequate bowel preparation assessed by the Boston Bowel Preparation Scale (BBPS). Secondary outcomes include bowel preparation completion rate, tolerability, adverse events, repeat colonoscopy rate, adenoma detection rate, and ingestion rhythm characteristics during bowel preparation. This study also aims to explore whether electrolyte beverage-assisted bowel preparation may improve bowel cleansing quality by influencing participants' ingestion rhythm and adherence during PEG intake.
