One-day vs two-day low-residue diets for bowel preparation: A randomized controlled trial assessing colonoscopy quality indicators

Öz

Background and Aims: Adequate bowel preparation is critical for high-quality colonoscopy. Although low-residue diets are recommended over clear liquid diets, the optimal duration of low-residue diets remains uncertain. This study aimed to compare the effectiveness of 1-day versus 2-day low-residue diets regimens in terms of bowel preparation quality and colonoscopy performance. Materials and Method: In this single-blind, randomized controlled trial, 179 patients scheduled for elective colonoscopy were assigned to either a 1-day (n = 89) or 2-day (n = 90) low-residue diets regimen, followed by a split-dose magnesium citrate with sodium picosulfate preparation. The primary outcome was bowel cleanliness assessed using the Boston Bowel Preparation Scale. Secondary outcomes included insertion and withdrawal times, cecal and ileal intubation rates, polyp detection rate, and adenoma detection rate. Results: Boston Bowel Preparation Scale total and segmental scores were similar between groups, except for significantly higher left colon scores in the 1-day low-residue diets group (p = 0.02). Insertion time was shorter in the 1-day group (4.61 vs. 4.83 minutes, p = 0.03), while withdrawal time, polyp detection rate, and adenoma detection rate were comparable (adenoma detection rate: 42.6% vs. 44.4%, p=0.48). No patient-related factors were significantly associated with bowel preparation quality. Conclusion: A 1-day low-residue diets regimen is as effective as a 2-day regimen for bowel cleansing and does not compromise colonoscopy performance. Shorter dietary restriction may enhance patient comfort without affecting procedure quality. Colonoscopy, bowel preparation, low-residue diet, adenoma detection rate, dietary duration
