Surveillance Intervals Calculations Based on US Multi-Society Task Force Guidelines. Final surveillance interval was defined as the lowest surveillance number combining personal history and findings at colonoscopy, comparing SRL status determined by true path (TP) vs optical path (OP) of polyps ≤ 5 mm. SRL: Surveillance Relevant Lesions. FHx: Family History. Hx: History. Lynch: Lynch syndrome. FAP: Familial Adenomatous Polyposis Syndrome. PJ: Peutz-Jeghers Syndrome.
