Objective: To prevent and reduce the risk of bleeding after endoscopic treatment of gastrointestinal polyps. Methods: Endoscopic simple nylon ligation or nylon ring ligation plus electrocoagulation combined therapy. Results: In the treatment group, a total of 36 polyps with diameter> 2cm were obtained in 33 cases. The cure rate was 97.3% and the hemorrhage rate was 2.7%. The control group was 48 cases with 52 polyps. The cure rate was 88.9% and the bleeding rate was 11.1%. CONCLUSIONS: Nylon loop ligation is an effective method for increasing the cure rate and preventing and reducing the incidence of bleeding in patients with crude pedicle or pedicle polyps> 2 cm in diameter
