Efficacy And Tolerability Of Asymmetric Split Regimen For Bowel Preparation

Summary

The investigators aimed to compare the efficacy for bowel cleansing of a split-dose regimen with a low morning dose of PEG solution (Asymmetric; 25% of the dose is given on the day of the procedure and 75% of the dose is given on the day before) with the standard split-dose regimen in patients undergoing screening and surveillance colonoscopy using a very low volume bowel preparation (1L PEG+Ascorbate). Consecutive outpatients undergoing screening and surveillance colonoscopy were enrolled in a randomized, single-blind, non-inferiority clinical trial. Patients were randomly assigned to: group A, asymmetric split dose regimen (0,75 L of PEG + ASC the day before and 0,25 L 2:30 hours before colonoscopy); group B, symmetric split dose regimen (0,5 L of PEG + ASC the day before and 0,5 L 3 hours before colonoscopy). Primary endpoint was the proportion of adequate bowel cleansing. Moreover, all patients filled in a validated, nurse-administered questionnaire assessing compliance, tolerability and safety of bowel preparation.
