Adequate bowel cleansing which is acceptable to the patient is a prerequisite for safe and effective colonoscopy. A 2-L polyethylene glycol solution containing ascorbic acid and electrolytes (PEG-Asc) is an alternative to sodium picosulphate + magnesium citrate (SPS-Mg) for bowel preparation. The aim of the current study is to compare PEG-Asc to SPS-Mg in terms of tolerability and efficacy.This was a single blind, randomized controlled trial. A blinded assessment of bowel cleansing was made by the attending endoscopist. Patients completed a questionnaire on the acceptability of the preparation.One hundred and thirty (130) consecutive patients attending for day case colonoscopy were randomly allocated to bowel preparation with PEG-Asc (n = 66) or SPS-Mg (n = 64). More patients found PEG-Asc to taste unpleasant (37.9 vs. 10.9
