What are the surveillance recommendations for a patient with a previous history of adenomatous colon polyps?
- After the removal of an adenomatous polyp, colonoscopy is the recommended method of surveillance because it has been shown to significantly reduce subsequent CRC incidence.
Colonoscopy Surveillance Recommendations

≤ 2 small tubular adenomas (< 1 cm) and only low-grade dysplasia | No earlier than 5 years |
Advanced neoplasia or 3 to 10 adenomas | 3 years |
More than 10 adenomas | Within 3 years |
Large, sessile polyp with incomplete excision | 2 to 6 months |
Negative surveillance colonoscopy | No earlier than 5 years |
Distal small (< 10 mm) hyperplastic polyps (no adenomas) | 10 years |
Sessile serrated polyp(s) < 10 mm with no dysplasia | 5 years |
Sessile serrated polyp(s) ≥ 10 mm | 3 years |
Sessile serrated polyp with dysplasia or serrated polyposis syndrome | 1 year |
