Development and Validation for Predicting Inadequate Bowel Preparation

Completed

• Conditions: Colonoscopy; Polyethylene Glycol; Cathartics
• Interventions: Other: no intervention

• Registration Number: NCT04290715
• Lead Sponsor: Ningbo No. 1 Hospital

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.
