Poster Session I – Poster of Distinction - A96 ADHERENCE TO PAST AND CONTEMPORARY POST-POLYPECTOMY SURVEILLANCE GUIDELINES

Abstract Background United States MultiSociety TaskForce (USMSTF) guidelines addressing post-polypectomy colonoscopy intervals were issued in 2012 and modified in 2020. Aims Assess post-polypectomy surveillance intervals adherence to USMSTF 2012 and 2020 recommendations. Methods We included patients with a past personal or index colonoscopy history of colon polyps from two tertiary hospitals. Procedural reports were reviewed and patients stratified according to index colonoscopy findings into: normal colonoscopy, 1–2 small (10 polyps, ≥1 adenoma ≥10 mm, at least one adenoma with high grade dysplasia, or a serrated polyp with dysplasia, or a traditional serrated adenoma. Recommended follow-up intervals were classified as earlier, later or adherent to 2020 guidelines, and compared to 2012 recommendations. Results Overall, 5,204 colonoscopies were included over 47 months. When the first follow-up index colonoscopy was normal (n = 963), adherence to follow-up was only 7.9% as per both guidelines, i.e.: 86.7% scheduled sooner than recommended (
