In conclusion, colon colorectal polypectomy is an effective method for the prevention and treatment
of colorectal cancer. However, regardless of how experienced the endoscopists are, there is always

a risk of delayed postoperative bleeding. There are many risk factors for DPPB, so endoscopists
should fully consider and implement effective intervention measures. Considerable attention should
be devoted to patients with the following risk factors: male sex, history of hypertension, history of
antithrombotic drugs and aspirin before surgery, number of removed polyps≥3, polyp size≥10 mm,

and pedunculated polyps. During the operation, precise hemostasis should be performed, and drug
therapy and active and rigorous follow-up should be used after surgery to form a multilink precise
preventive intervention system. As it is difficult to eliminate the influence of the confounding factors
examined herein, the conclusions of this study need to be further confirmed by large-scale

prospective clinical randomized controlled studies with high quality and unified standards.
