Decision at stakechoosing cold versus hot snare resection for large non-pedunculated colorectal polyps
After polyp removal, assign the next colonoscopy surveillance interval using USMSTF 2020 based on polyp number, size, and histology (e.g., 1-2 tubular adenomas <10 mm 7-10 years; 3-4 tubular adenomas <10 mm 3-5 years; 5-10 tubular adenomas <10 mm, any adenoma ≥10 mm, or adenoma with tubulovillous/villous histology or high-grade dysplasia 3 years; >10 adenomas 1 year with polyposis evaluation; and for serrated polyps, 1-2 sessile serrated lesions <10 mm 5-10 years, 3-4 sessile serrated lesions <10 mm or a hyperplastic polyp ≥10 mm 3-5 years, and a sessile serrated lesion ≥10 mm or with dysplasia or a traditional serrated adenoma 3 years), and apply the shortest interval indicated when findings are mixed. …

Our full summary of this standard
After polyp removal, assign the next colonoscopy surveillance interval using USMSTF 2020 based on polyp number, size, and histology (e.g., 1-2 tubular adenomas <10 mm 7-10 years; 3-4 tubular adenomas <10 mm 3-5 years; 5-10 tubular adenomas <10 mm, any adenoma ≥10 mm, or adenoma with tubulovillous/villous histology or high-grade dysplasia 3 years; >10 adenomas 1 year with polyposis evaluation; and for serrated polyps, 1-2 sessile serrated lesions <10 mm 5-10 years, 3-4 sessile serrated lesions <10 mm or a hyperplastic polyp ≥10 mm 3-5 years, and a sessile serrated lesion ≥10 mm or with dysplasia or a traditional serrated adenoma 3 years), and apply the shortest interval indicated when findings are mixed. Confirm complete resection and adequate prep before applying an interval, and use site-check/tumor-board pathways for piecemeal resection and malignant (T1) polyps. Refer for genetic evaluation when Lynch, FAP/AFAP/MAP, or serrated polyposis syndrome criteria are met.
