Summary

This trial is testing new endoscopic imaging techniques to see if they're better than the current gold standard (chromo-endoscopy) for detection neoplastic lesions in patients with longstanding ulcerative colitis.

Who is the study for?
This trial is for adults over 18 with long-term ulcerative colitis (at least 8 years since diagnosis or pancolitis, and at least 10 years for left-sided colitis). They must have had a previous endoscopy over a year ago and be able to give informed consent. It's not for those currently with active ulcerative colitis, personal history of colorectal cancer, allergy to methylene blue, or pregnant women.
What is being tested?
The study compares traditional chromoendoscopy against newer techniques like NBI, FICE, and I-scan in detecting precancerous changes in patients with longstanding ulcerative colitis. The goal is to see if these new methods are as effective but more efficient than the current gold standard.
What are the potential side effects?
Potential side effects may include discomfort from the endoscopic procedure itself such as cramping or bloating. Allergic reactions could occur in those sensitive to dyes used in chromoendoscopy but this would exclude them from participation.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
The difference in total number of neoplastic lesions detected by chromoendoscopy and virtual chromoendoscopy
Secondary study objectives
Duration of total endoscopic procedure time and of endoscopic procedure time during retraction for each technique.
The difference in neoplasia detection rate (i.e. the number of patients with at least one neoplastic lesion) between chromoendoscopy and virtual chromoendoscopy.
The difference in the ratio number of neoplastic lesions/ total number of lesions between chromoendoscopy and virtual chromoendoscopy
Other study objectives
The difference in total number of non-neoplastic lesions detected by chromoendoscopy and virtual chromoendoscopy

Awards & Highlights

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.
