01Start 02Decision Polyp Findings
- Normal/hyperplastic
- Low-risk adenoma
- High-risk adenoma
03End 10-Year Interval
No adenomas, only hyperplastic rectosigmoid
04Action Low-Risk Adenoma
1-2 tubular adenomas <10mm
05End 7-10 Year Interval
Consider 7 years if family history
06Action High-Risk Adenoma
≥3 adenomas, ≥10mm, villous, HGD
07End 3 Year Interval
If ≥10 adenomas: 1 year
08Action Serrated Polyps
SSP ≥10mm or with dysplasia
09End 3-5 Year Interval
Based on size/dysplasia
