The management of colorectal diminutive adenomatous polyps using pit pattern classification with magnifying chromoendoscopy

Interventions: patients whose DAPs with type IIIL PIT were left untreated. patients whose all neoplastic polyps including DAPs were resected. patients without any adenomatous polyp. Primary outcome(s): The primary goal is to address the hypothesis that after two complete colonoscopies with the removal of all polyps detected, the incidence of clinically significant lesions would not be different between patients undergoing two further follow-up examinations and those undergoing just one. Clinically significant lesions are defined as index lesions (IL): if they are larger than 10mm; if they have high-grade dysplasia; or if they are invasive. Study Design: Parallel Non-randomized
