Abstract

Objective: Initial assessment of cold polypectomy below 10mm, comparison with hot polypectomy. Method: A prospective descriptive study on 106 patients from the Center for Gastroenterology-Hepatology, Bach Mai Hospital, from May 2022 to August 2022. Results: 54/106 patients performed the cold polyp removal method. The mean polyp size of cold polypectomy was smaller than that of hot polypectomy (5.80±1.30 vs 7.67±1.82, p<0.0001). Cold polypectomy is mainly performed on flat, elevated lesions lesions -IIa (79.6%). 100% of cases of cold polypectomy did not need submucosal injection compared to the hot polypectomy group, the rate was 78.9% (p<0.0001). Clips prevented bleeding and perforation complications higher in the hot polypectomy group than in the cold polypectomy group (38.5% vs 3.7%, p<0.0001). In the study, there were no complications of late bleeding or perforation after polypectomy. Conclusion: Cryosection of cold polypectomy is safe in the small polyp group (5-10mm), less need to use lifting tools, and clips than in the hot polypectomy.
