Endoscopic control of polyp burden and expansion of surveillance intervals in serrated polyposis syndrome

Abstract

Most patients achieved control of polyp burden with 2 to 3 colonoscopies over 1 to 2 years. After reaching control, 60 patients returned at intervals up to 24 months with no incident cancers and no surgeries required. Expansion of surveillance intervals to 24 months is effective and safe for many patients with SPS who reach control of polyp burden.
