Core Tip
Core tip: Oral sodium phosphate (NaP) is used for bowel preparation before colonoscopy. It is desirable to reduce the dose of NaP due to the potential adverse events associated with NaP. In this study, we evaluated the efficacy of a colonoscopy preparation that utilized a reduced dose of NaP and an adjunct. This study demonstrated that 30 g NaP in combination with sodium picosulfate can be useful for bowel preparation prior to colonoscopy in Japanese populations. This report is the first to evaluate the efficacy of a bowel preparation using the minimally effective dose of NaP and an adjunct.
