Study information
Scientific title
Randomised controlled trial of Narrow Band imaging with magnification (NBI) versus white light endoscopy for dysplasia detection in ulcerative colitis surveillance
Acronym
Study hypothesis
Does a new colonoscopic viewing technique called narrow band imaging (NBI) help doctors detect more patients with at least pre-cancerous area (dysplasia associated lesion or mass, DALMs) than conventional colonoscopy using white light alone?

Primary outcome measures
The study is to determine if the use of a narrow band of light can help detect more pre-cancerous or cancerous areas than the normal white light used for detection. The outcome measure is to determine the numbers of patients with at least one cancer in either group.
Secondary outcome measures
Added 17 July 2008:
1. Are more precancerous lesions found in total with NBI?
2. Are more advanced precancerous lesions found with NBI?
3. Are more patients found with more than one precancerous lesion with NBI?
4. How many lesions are successfully completely removed with endoscope?
