Adherence to the recent guidelines of the U.S. Multi-Society Task Force on Colorectal Cancer (USMSTF) was also analyzed.Results: In total, 196 endoscopists completed the survey. The most preferred first surveillance intervals were: a 5-year interval after the removal of 1\u20132 tubular adenomas &lt; 10 mm; a 3-year interval after the removal of 3\u201310 tubular adenomas &lt; 10 mm, adenomas \u2265 10 mm, tubulovillous or villous adenomas, \u2264 20 hyperplastic polyps &lt; 10 mm, 1\u20134 sessile serrated lesions (SSLs) &lt; 10 mm, hyperplastic polyps or SSLs \u2265 10 mm, and traditional serrated adenomas; and a 1-year interval after the removal of adenomas with highgrade dysplasia, &gt;10 adenomas, 5\u201310 SSLs, and SSLs with dysplasia. In piecemeal resections of large polyps ( &gt; 20 mm), surveillance colonoscopy was mostly preferred after 1 year for adenomas and 6 months for SSLs. The mean USMSTF guideline adherence rate was 30.7%. The largest proportion of respondents (40.8%\u201355.1%) discontinued the surveillance at the patient age of 80\u201384 years.Conclusions: A significant discrepancy was observed between the preferred post-polypectomy surveillance intervals and recent international guidelines. Individualized measures are required to increase adherence to the guidelines.<\/jats:p>","DOI":"10.5217\/ir.2023.00109","type":"journal-article","created":{"date-parts":[[2024,4,25]],"date-time":"2024-04-25T23:55:07Z","timestamp":1714089307000},"page":"186-207","update-policy":"https:\/\/doi.org\/10.5217\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A
