Anatomic Distribution of Sessile Serrated Adenoma/Polyp With and Without Cytologic Dysplasia

Abstract

Sessile serrated adenomas/polyps with and without cytologic dysplasia and carcinoma are predominantly found in the cecum and ascending colon, whereas there is low prevalence in both the transverse and distal colon. Confirmation of previously published data regarding demographics of advanced lesions among a different cohort and including newer (broader) criteria suggests these criteria are valid.
