摘　　要：Colorectal cancer(CRC)is the third most commonly diagnosed malignant tumor in the world.The past few years have seen a remarkable increase in both incidence and mortality of CRC in developing countries like China,posing a serious threat to human health.It is currently believed that about 70%of colorectal cancers are derived from conventional adenomas and 30%are derived from serrated adenomas.[1]As reported,CRC incidence rates per 10,000 person-years were 20.0 for advanced adenoma and 9.1 for non-advanced adenoma.[2]Colonoscopy,as an important tool for CRC screening and follow-up,can prevent the development of CRC by detecting and removing precancerous lesions,thereby effectively reducing the incidence and mortality.Current guidelines for post-polypectomy surveillance mostly recommend a 3-to 10-year interval according to baseline risk stratification.[3]However,there is no such guideline in China yet and doctors tend to perform the next colonoscopy within 1 year,which is much shorter than current international recommendations.
