Virtual versus dye-based colonoscopy for bowel disease surveillance
Part of Cancer, Digestive system clinical trials.
This study compares two ways to examine your colon during a surveillance colonoscopy for IBD: a virtual method using standard light and a dye-based method that sprays a blue dye to highlight abnormal areas. The goal is to see which method is better at finding precancerous changes to help prevent colon cancer.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be at least 18 years old.
- You must have had inflammatory bowel disease for at least 8 years, or have PSC, or have a first-degree relative with colorectal cancer.
- You must have extensive colitis or Crohn's affecting a third or more of your colon (if you have IBD).
- You must not have had colorectal cancer or colon removal surgery.
- You must not be pregnant or have any reason that makes dye use unsafe.

This study compares two methods used during colonoscopy to help find polyps in the colon. It tests whether a special light technique (linked-color imaging) or a dye spray (indigo carmine) works better for spotting adenomas, which are growths that can turn into cancer. If you are at higher risk for colorectal adenomas, this trial may help improve detection.
This study tests two new imaging technologies used during a colonoscopy to better detect and describe growths (polyps) in the colon. This may help doctors find and remove pre-cancerous polyps more accurately during the same procedure.
This study tests a new magnetic flexible endoscope for examining the colon in people with stable inflammatory bowel disease, such as ulcerative colitis or Crohn's disease. The aim is to see if this gentler approach can help visualize the colon more comfortably.
This study compares a newer, possibly greener imaging method (IBUS) with standard colonoscopy and enterography for people with ulcerative colitis (UC) or Crohn's disease (CD). The goal is to see if IBUS is as helpful and produces less waste or carbon emissions.
This study compares different special camera techniques during colonoscopy to see which best finds early abnormal (pre-cancer) changes in people with long-term ulcerative colitis. It may help doctors improve how they screen and monitor your colon over time.
This study compares two ways of looking at the colon during a routine check-up to find early signs of cancer in people with inflammatory bowel disease (IBD). One method uses a special light, and the other uses a dye. The goal is to see which is better at finding these signs.
