About

Background 2L polyethylene glycol plus ascorbic acid (PEGA) is known to be as effective as standard 4L polyethylene glycol for bowel preparation. However, the volume of this regimen is still large. Therefore, the present investigators evaluated the potential of 1L PEGA with prepackaged low-residue diet (PLD) for an alternative to 2L PEGA. Aim: To evaluate efficacy of 1L PEG with ascorbic acid combined with prepackaged low-residue diet as bowel preparation for colonoscopy. Methods: The subjects were randomly assigned to either groups. PEGA group received 2L PEGA split regimen. PLD group received PLD on the day preceding colonoscopy and 1L PEGA on the morning of colonoscopy. One blinded physician performed colonoscopy and evaluated the degree of bowel preparation using Boston bowel preparation score (BBPS). A questionnaire regarding tolerability and safety were also gathered.
