Abstract: Objective  To compare the efficacy of endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD) for the treatment of colonic thickpedicled polyps, to analyze the intraoperative and postoperative effects of these two methods in order to provide a reference for endoscopic diagnosis and treatment.Methods  A total of 100 patients were randomly divided into EMR group and ESD group, with 50 cases in each group. The relevant clinical data of two groups were collected, includingthe lesion size, bleeding risk, operation time, positive rate of pathological cutting margin and followup differences. Results  The duration of operation in ESD group was significantly longer than that in EMR group (P<0.05), and the incidence of intraoperative bleeding (13/50) in ESD group was significantly higher than that in EMR group (1/50).Conclusion  For colonic thickpedicled polyps with a diameter greater than 1.0 cm, both EMR and ESD are safe and effective therapies. And EMR group has certain advantages in ease of operation and bleeding rate.
