AimQuality of bowel cleansing significantly increases the shorter the time between bowel solution intake and endoscopic examination. We tested the efficacy and patient tolerability following a modified polyethylene glycol electrolyte (PEG) splitting regimen.MethodsThis was a prospective, single-blind, randomized, study. Patients were assigned to receive either PEG 4 L the afternoon before colonoscopy or PEG 3 L the day before and 1 L 3 h before the procedure the day of colonoscopy.ResultsThe study population consisted of 336 patients, including 168 participants in each study arm. Although the bowel preparation quality was similarly quoted as excellent/good following the split and full regimen (95.2% vs 92.8%; p = 0.3), a significant (p < 0.0001) shift from good towards an excellent preparation (26.8% vs 68.4%) was observed following the split regimen as compared to the full regimen (55.4% vs 37.5%). The incidence of side-effects did not differ. When patients were asked about a future preparation if needed, 69% and 31% following the split and full regimen, respectively, declared to accept again the same preparation, the difference being statistically significant (p < 0.001).ConclusionsOur data found that an excellent bowel cleansing could be frequently achieved by simply modifying the split regimen from the standard PEG 2 plus 2 L to 3 plus 1 L.
