The study will include 70 adults at 3 Canadian hospitals: 60 people with ulcerative colitis or Crohn's disease affecting the colon, and 10 people without IBD who are having colonoscopy for routine colorectal cancer screening or surveillance. During the colonoscopy, participants will receive intravenous fluorescein, and the imaging system will record fluorescence in the colon as the scope is withdrawn. The main goal is to find out whether this method can be used safely during routine colonoscopy and whether it can produce usable measurements of mucosal permeability. The study will also examine whether these measurements are related to standard measures of inflammation seen during endoscopy, in biopsy samples, and in ex vivo Ussing chamber testing at the McMaster site. The control group will help define what normal fluorescence and permeability look like. This study is intended to provide early data on whether this approach could become a useful new way to assess barrier dysfunction in IBD.",[23,24],"Inflammatory Bowel Disease (Crohn's Disease; Ulcerative Colitis)","NON-IBD",[26,27],"IBD, CD, UC","Non-IBD","NOT_YET_RECRUITING","2026-04-17",{"date":31,"type":32},"2026-04-23","ACTUAL",{"date":34,"type":19},"2026-04-01",{"date":36,"type":19},"2027-02-01",{"name":38,"class":39},"Hamilton Health Sciences Corporation","OTHER"]
