Abstract
INTRODUCTION: 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. METHODS: 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. RESULTS: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%, P < 0.001) and more patients found PEG-Asc to be a more distressing preparation than SPS-Mg (15.1 vs. 4.7%, P = 0.043). However, there was no difference in the proportion of patients being able to complete bowel preparation (PEG-Asc vs. SPS-Mg, 92.4 vs. 93.8%, P = 0.520). There was no detectable difference between PEG-Asc and SPS-Mg in the quality of cleansing with a good or very good preparation being reported by the endoscopist in 46.9 and 54.5% of cases, respectively (P = 0.242). CONCLUSIONS: More patients find PEG-Asc to taste unpleasant and to be a more distressing preparation than SPS-Mg. However, there was no detectable difference between PEG-Asc and SPS-Mg in bowel cleansing prior to colonoscopy.
