Abstract: Colorectal polyp is a common disease and the common cause of painless hematochezia in children. With the popularization of colonoscopy technology in children，more and more children with colorectal polyps have been diagnosed and treated. Colorectal polyps often have symptoms in early childhood. Colonoscopy can confirm the location，size and quantity of polyps，and pathological examination can be carried out to determine their nature. Colorectal polyps in children include inflammatory polyps，hamartomatous polyps，adenomatous polyps and other types. Pediatricians need to raise awareness and actively perform colonoscopy in children with symptoms or a relevant family history.
