Pre-procedure Modle Predicts Bowel Preparation Quality Prior Colonoscopy

• Conditions: Bowel Preparation; Colonoscopy

• Registration Number: NCT04160104
• Lead Sponsor: Air Force Military Medical University, China

Brief Summary

Bowel preparation is closely llined to the quality of colonoscopy, inadequate bowel preparation (IBP) could lead to higher miss rate of adenomas, patients' discomfort and higher health expense. For the patients with possible IBP before the examination, it may be better to cancel the colonoscopy and repeat bowel preparation through modified or enhanced strategies. Thus, it is important to set up a model to predict the quality of bowel preparation individually.
