High-quality bowel cleansing is critical to effective colonoscopy. Studies in the past decade have demonstrated that many clinical practices continue to have rates of adequate preparation as low as 60% to 80%.~Low-volume preparations for colonoscopy are designed to improve patient tolerability, another important aspect of bowel preparation. In addition, low-volume preparations should ideally not sacrifice efficacy. There are few data comparing the efficacy of available low-volume bowel preparations.~In this study, we describe a prospective, single-blind, randomized, controlled trial comparing oral sulfate solution (OSS) (SUPREP, Braintree Laboratories, Braintree, Mass) with low-dose polyethylene glycol plus ascorbic acid (2-L PEG/Asc).
The aims of the present study is to compare oral sulfate solution (OSS) with low-dose polyethylene glycol plus ascorbic acid (2-L PEG/Asc) for bowel cleansing efficacy.
