Abstract:
The risk of colorectal cancer in case of IBD-related pancolitis reaches 2% after 10 years follow-up, 8% after 20 years up to 18% at 30 years, and was probably over-estimated in the first series. Chromoendoscopy appears to be helpful in the surveillance of IBD, and moreover recommended, using carmine indigo or methylene blue with a well-standardized procedure. Its place regarding other techniques like virtual coloration has to be clarified with randomized studies. The chromoendoscopy allows the operator to perform targeted biopsies, which appear to be more efficient for the detection of dysplasia than systematic biopsies performed every 10 cm. Nevertheless, it is too soon to remove systematic biopsies from scientific recommendations.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
