Aims To determine the incidence of serrated lesions in a non-academic hospital with special interest in serrated neoplasia.

Methods Prospectively collected FIT positive screening cohort from august 2018 until november 2019 were studied to asses serrated lesions and serrated polyposis sindrome.

Results We performed 222 screening colonoscopies after a positive FIT in which we found 304 SSL with at least one SSL in 98 patients (44,14%) . Of these, 25 were advanced SSL (>10mm or with dysplasia) in 14 patients (6,31%) and 53 clinically relevant SSL (advanced SSL or >5mm and proximal to splenic flexure) in 28 patients (12,61%).

5 patients (2,25%) were diagnosed of serrated polyposis syndrome in the screening colonoscopy. All of them met criterion I of the 2019 WHO classification.

Conclusions In a center with special interest in serrated neoplasia, the incidence of serrated lesions (15,1-19,5%), advanced SSL (1,3-1,6%), clinically relevant SSL (2,1-7,9%) and SPS (0,03-0,5%), is greater than the incidence published until now.
