Background: In physically less fit patients and patients requiring repeated exams, adequate bowel preparation for colonoscopy remains problematic, particularly because patients need to drink large volumes of unpleasant-tasting fluids. A further concern is potential unwarranted fluid shifts.
Aims: This study aimed to compare the safety and burden of a small-volume sodium picosulphate/magnesium citrate preparation (SPS-MC) with a 2-l ascorbic-acid-enriched polyethylene glycol solution plus bisacodyl pretreatment (PEG-Asc+B).

Background: Because of its volume, adequate bowel preparation remains problematic in physically unfit patients.
Objective: This study aimed to compare a small-volume sodium picosulfate/magnesium citrate preparation with a 2-L ascorbic acid-enriched polyethylene glycol solution plus bisacodyl.
Design: This study has a noninferiority design, assuming that ascorbic acid-enriched polyethylene glycol solution plus bisacodyl is 70% efficacious in achieving an Ottawa score ≤7 and accepting a difference in success rate of <15% with a target enrollment of 146 patients per group.
