Abstract: Objective　To explore the clinical features of colorectal polyps in children and the therapeutic value of endoscopic mucosal resection (EMR). Method　The clinical data of 670 children with colorectal polyps who underwent EMR immediately after the diagnosis from 2012 to 2017 were retrospectively analyzed. Results　Among 670 children (423 males, 232 females), the average diagnosis age was 4.50±2.69 years old, with high incidence at the age of 3 to 6 years (43.4%). The clinical presentation was dominated by hemafecia (90.3%). Most of the polyps were solitary (92.5%), mostly in the rectum (49.0%) and sigmoid colon (35.2%) with diameter <2 cm (78.9%). For polyps with diameter ≥2 cm, titanium clips should be used to close the wounds, while for those with diameter <2 cm, titanium clips have no effect on postoperative bleeding. Postoperative bleeding mainly occurred on the first day after operation. Postoperative pathological findings suggested that juvenile polyp was predominant. Conclusions　Colorectal polyps are most common in preschool boys and most of them are juvenile polyps. EMR supplemented with metal titanium clips can reduce postoperative bleeding.
