- Abstract: BACKGROUND/AIMS: In the present study, we evaluated the efficacy and tolerability between same-day bowel preparation protocols using 2 sachets of Picosulfate and a 4 L split-dose polyethylene glycol (PEG) bowel preparation for afternoon colonoscopy. METHODS: The study had a single-center, prospective, randomized, and investigator-blinded, non-inferiority design. We evaluated bowel preparation quality according to the Ottawa scale, patient tolerability, compliance, incidence of adverse events, sleep quality, and polyp/adenoma detection rate. RESULTS: Among the 196 patients analyzed (mean age, 55.3 years; 50.3% men), 97 received the same-day regimen of 2 sachets of picosulfate (group A) and 99 received the 4 L split-dose PEG regimen (group B). The Ottawa score of the total colon was 4.05+/-1.56 in group A and 3.80+/-1.55 in group B (P=0.255). The proportion of patients having adequate bowel preparation in the same-day picosulfate group (61.5%) was slightly less than the 4 L PEG group (71.3%); however, the difference was not statistically significant (P=0.133). Tolerability of the group A regimen was superior to that of the group B regimen (P<0.000). The same-day picosulfate regimen was associated with fewer adverse events, such as abdominal bloating (P=0.037) and better sleep quality (P<0.000). CONCLUSIONS: The same-day picosulfate regimen and the 4 L split-dose PEG regimen had similar efficacy in bowel preparation for afternoon colonoscopy. However, the same-day picosulfate regimen was easier to administer, produced fewer adverse events, and enabled better sleep quality.
