Summary

This study tests whether a pre-packaged low-residue nutrition formula (Maifu Changqing®) can improve bowel cleanliness and comfort during colonoscopy preparation for 1,000 adults with inflammatory bowel disease (IBD). Participants will be randomly assigned to receive either the special diet or standard preparation. The goal is to see if this approach makes the prep process more tolerable while still being effective.
