Brief Summary

High-quality colonoscopy is considered the gold standard for the detection and prevention of colorectal cancer, and its efficacy is predicated on optimal colon cleansing.However, about 18%-35% of patients were still reported to suffer inadequate bowel preparation. Although several predictive models exist, the current guideline indicates that there is insufficient evidence to recommend the use of a predictive model for clinical practice.

Outcome Measures

Primary Outcomes (2)

  • quality of bowel preparation

    The OBPS is a validated scoring system with scores between 0 and 14, where 0 is the best score. The score comprises a sub score 0-4 for each colon segment: right, transverse and rectosigmoid colon. In addition, a score 0-2 is added to indicate the total amount of luminal fluid. For all participants, OBPS score will be used when the colonscopy is inserting.

    A colonoscopy procedure

  • quality of bowel preparation

    The BBPS is another validated scoring system with scores between 0 and 9, where 9 is the best score. The score comprises a sub score 0-3 for each colon segment: right, transverse and left colon. For all participants, BBPS score will be used when colonscopy is withdrawing.
