Younger Patients Do Not Develop More Advanced Polyps on Surveillance Colonoscopy Than Their Index Colonoscopy When Compared With Older Patients.

Background And Goals: Colonic polyp surveillance guidelines are based on data from patients 50 and above. Given the recent lowering for colorectal cancer (CRC) screening to age 45, the aim of this study was to assess whether existing colonic polyp surveillance guidelines are appropriate to use in younger patients.

Materials And Methods: We performed a retrospective cohort study of patients who underwent 2 colonoscopies within a 10-year period.
