Core Tip
Core tip: Same day preparation with 4-L sulfa-free polyethylene glycol (4-L SF-PEG) for afternoon colonoscopy is more effective and better tolerated than consumption the day prior. However, no study has compared different bowel preparation solutions administered in their entirety in the morning of an afternoon colonoscopy. We compared the cleansing efficacy and patient satisfaction of same day ingestion of 4-L SF-PEG vs 2-L PEG solution with ascorbic acid (Asc) in patients undergoing afternoon colonoscopy. We found 4-L SF-PEG to provide superior cleansing with less bloating as compared to 2-L PEG + Asc.
