Colonoscopy Clinical Trial
Official title:
1L Morning-only Polyethylene Glycol Plus Ascorbic Acid With Prepackaged Low-residue Diet Versus 2L Polyethylene Glycol Plus Ascorbic Acid for Bowel Preparation: a Randomized Trial
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.
