N2 - Serrated adenomas are categorized as sessile serrated adenomas (SSAs) and traditional serrated adenomas (TSAs). SSAs are more prevalent in the proximal colon and lack classic dysplasia, whereas TSAs are more prevalent in the rectosigmoid and have cytologic dysplasia. Serrated adenomas may progress to colorectal adenocarcinoma through diverse molecular alterations. Colonoscopy is the only test for the early detection of serrated adenomas that allows inspection of the entire colon and same-session biopsy sampling or polypectomy, if necessary. If an endoscopic biopsy at the right colon reveals SSA without cytologic dysplasia or biopsy at the rectosigmoid reveals SSA or TSA, those polyps should be excised or surgically resected as necessary. Postpolypectomy surveillance for removed SSAs without dysplasia and TSAs must be performed at 5- and 3-year intervals, respectively, with colonoscopy to prevent recurrence and progression to colorectal adenocarcinoma.
