1-liter polyethilene glycol (1l-peg) bowel preparation vs. 4l- peg for colon cleansing among inpatients: a propensity score matching analysis from a large multicenter prospective cohort

Aims The inpatient status is one of the strongest independent predictors for inadequate colon cleansing. The best strategy for bowel preparation among inpatients is yet unknown. Based on experts’ opinion, high-volume, 4L polyethilene glycol (PEG) solution should be the standard-of-care in this setting. We aimed to determine whether the novel 1L-PEG plus ascorbate prep is associated with increased colon cleansing among inpatients.
