Outcome Measures

Primary Outcomes (1)

  • satisfactory bowel preparation

    The aim of this study was to test the quality of bowel preparation and tolerability of a low-volume (2 L) PEG regimen for colonoscopy compared to single (4 L) or split-dose (2 L + 2 L) treatments. The quality of colonic preparation was assessed by the Boston bowel preparation scale.Satisfactory colon preparation was considered when scores of the Boston bowel preparation scale were 2/3; otherwise, the procedure was considered unsatisfactory preparation.

    at the moment of colonoscopy

Secondary Outcomes (1)

  • tolerability with bowel preparation

    just before to start the colonoscopy and before any sedative be administered
