Summary

This study involves 1,000 adults with inflammatory bowel disease (IBD) who need a colonoscopy. Researchers want to see how well current bowel preparation methods work and what factors lead to poor preparation. The goal is to create a tool that predicts which patients might have trouble, so doctors can tailor the prep to each person.
