Low detection rate of advanced neoplasia within 5 years after polypectomy of small serrated adenoma.

Aim: Patients with small serrated adenomas (SAs) (<10 mm) often undergo surveillance colonoscopy before the routine recommended time. We aimed to determine the appropriate surveillance intervals following polypectomy of small SAs for symptomatic patients.

Method: We retrospectively reviewed the data of 638 patients, including 122 cases and 516 controls.
