 Lesion found  Surveillance interval (y)
 Serrated polyposis  1
 Serrated polyp with cytological dysplasia  3
 Serrated polyp proximal to the splenic flexure  3
 Serrated polyps ≥10 mm  3
 Serrated polyps <10 mm and distal to the splenic flexure  10
   

Serrated polyps include HPs, sessile serrated adenomas and TSAs.

World Health Organization defines hyperplastic (serrated) polyposis as (1) 5 histologically diagnosed HPs proximal to the sigmoid colon, of which 2 are 10 mm in diameter; or (2) any number of HPs that occur proximal to the sigmoid colon in an individual who has a first-degree relative with HPS; or (3) 30 HPs of any size that are distributed throughout the colon.
