The aim of the expert working group on surveillance after removal of colorectal neoplasia is to improve the quality of the scientific evidence regarding post-polypectomy surveillance, including the clinical impact on patients and the demands on the health system associated with different surveillance programs tailored to a patient’s specific history.
