This is a prospective, observational, multicenter, collaborative research project that will explore the earlier stages of IBD, before the onset of the first symptoms of the disease. This novel approach constitutes an innovative strategy on the research on the natural history of the disease. The study will be carried out based on colorectal cancer screening colonoscopies, recruiting all patients with a new diagnosis of IBD in this setting. These patients will undergo follow-up visits every 6 months for 10 years and the clinical information will be enriched with longitudinal multi-omic analyses.~Two additional control groups will be identified, including patients with new-onset symptomatic IBD in the last 3 months and healthy controls (with normal screening colonoscopy).
The purpose of this study is to evaluate disease progression, in terms of development of symptomatic disease and complications associated with IBD (e.g. fistula, abscess, stricture).
