Bowel Preparation Colonoscopy

ClinConnect Summary

This clinical trial is focused on improving bowel preparation before colonoscopy procedures for patients with conditions like Crohn's disease and ulcerative colitis. The study aims to understand how bowel preparation is currently done in hospitals across China, especially after new guidelines were introduced in 2023. Researchers want to find out what factors lead to poor bowel preparation, so they can create better, personalized preparation plans for individual patients.

To participate in this trial, you must be over 18 years old and scheduled for a colonoscopy. It's important that you can give written consent and do not have certain health issues, such as severe heart or liver problems, or a history of certain cancers. Participants will help researchers learn more about how to improve colonoscopy preparation, which can ultimately lead to better outcomes for patients. If you’re interested, please talk with your healthcare provider to see if you meet the eligibility criteria and to learn more about what being part of this study involves.
