Efficacy and safety of cold snare polypectomy in treatment of gastric polyps with a diameter of 5-10 mm

Objective To investigate the efficacy and safety of cold snare polypectomy (CSP) in the treatment of gastric polyps with a diameter of 5-10 mm. Methods A total of 161 patients with 313 polyps who were found to have sessile gastric polyps with a diameter of 5-10 mm by gastroscopy and underwent gastric polypectomy in Laoshan Campus, The Affiliated Hospital of Qingdao University, from 2021 to 2022 were enrolled, and according to the surgical procedure for polypectomy, they were divided into CSP group with 88 patients (162 polyps) and hot snare polypectomy (HSP) group with 73 patients (151 polyps). The two groups were compared in terms of the complete resection rate and en bloc resection rate of gastric polyps, immediate bleeding rate, the rate of use of titanium clip during surgery, delayed bleeding rate, delayed gastric perforation rate, postoperative infection rate, and various inflammatory indicators after surgery. Results There were no significant differences between the two groups in the complete resection rate and en bloc resection rate of gastric polyps, immediate bleeding rate, delayed bleeding rate, delayed gastric perforation rate, and postoperative infection rate (P>0.05), and compared with the HSP group, the CSP group had a significantly lower rate of use of titanium clip (χ2=13.482,P<0.05). Conclusion CSP is safe and effective in the treatment of gastric polyps with a diameter of 5-10 mm, and therefore, it holds promise for clinical application.
