A low-residue diet (LRD) is recommended as part of bowel preparation before a colonoscopy. However, the optimal duration of the LRD is unclear. A retrospective cross-sectional study was therefore conducted at E-Da Dachang Hospital. We compared bowel preparations using the Aronchick score and other quality metrics during two consecutive periods: May 2019 to December 2019 (3-day LRD) and January 2020 to August 2020 (1-day LRD). A total of 2823 patients were enrolled (1592 in the 3-day LRD group and 1231 in the 1-day LRD group). The most common bowel cleansing agent was sodium picosulfate and magnesium citrate (SPMC, 84.2%), followed by polyethylene glycol (PEG, 10.0%) and sodium phosphate (5.8%). Compared with patients in the 3-day LRD group, patients in the 1-day LRD group had higher SPMC use (88.1% vs 81.3%, P < .001) and supplemental laxative use (25.9% vs 19.3%, P < .001).The proportion of adequate bowel preparation (84.2% vs 85.1%, P = .563), cecal intubation rate, adenoma detection rate, and right-side adenoma detection rate were not significantly different between 1-day LRD and 3-day LRD groups. More advanced adenomas (5.9% vs 3.4%, P = .002) and sessile serrated lesions (8.9% vs 6.3%, P = .014) were observed in the 1-day LRD group. In addition, the types of laxatives (SPMC, sodium phosphate, and PEG) and the use of supplemental laxatives did not affect bowel preparation scores. In conclusion, a 1-day LRD led to bowel preparation similar to that achieved through a 3-day LRD regardless of the type of primary cleansing agent or the use of supplemental laxatives.

Background and AimAlthough studies have shown that the quality of bowel preparation with low‐residue diet (LRD) is as effective as that of clear fluid diet (CLD), there is currently no consensus on how long an LRD should last. The aim of this study was to compare a 1‐day versus 3‐day LRD on bowel preparation before colonoscopy.MethodsA systematic review search was conducted in MEDLINE/PubMed, EMBASE, Web of Science, and Cochrane database from inception to April 2023. We identified randomized controlled trials (RCTs) that compared 1‐day with 3‐day LRD bowel cleansing regiments for patients undergoing colonoscopy. The rate of adequate bowel preparation, polyp detection rate, adenoma detection rate, tolerability, willingness to repeat preparation, and adverse events were estimated using odds ratios (OR) and 95% confidence interval (CI). We also performed meta‐analysis to identify risk factors and predictors of inadequate preparation.ResultsFour studies published between 2019 and 2023 with 1927 participants were included. The present meta‐analysis suggested that 1‐day LRD was comparable with 3‐day LRD for adequate bowel preparation (OR 0.89; 95% CI, 0.65–1.21; P = 0.45; I2 = 0%; P = 0.52). The polyp detection rate (OR 0.94; 95% CI, 0.77–1.14; P = 0.52; I2 = 23%; P = 0.27) and adenoma detection rate (OR 0.87; 95% CI, 0.71–1.08; P = 0.21; I2 = 0%; P = 0.52) were similar between the groups. There were significantly higher odds of tolerability in patients consuming 1‐day LRD compared with 3‐day LRD (OR 1.64; 95% CI, 1.13–2.39; P < 0.01; I2 = 47%; P = 0.15). In addition, constipation was identified as the independent predictor of inadequate preparation (OR 1.98; 95% CI, 1.27–3.11; P < 0.01; I2 = 0%; P = 0.46).ConclusionThe present study demonstrated that a 1‐day LRD was as effective as a 3‐day CLD in the quality of bowel preparation before colonoscopy and significantly improved tolerability of patients. In addition, constipation is an independent risk factor of poor bowel preparation, and the duration of LRD in patients with constipation still needs further clinical trials.
