Effectiveness and safety of different methods of removal of medium —sized benign colorectal polyps using cold snare polypectomy

Background. The study is devoted to assess the efficacy and safety of the hot snare polypectomy (endoscopic mucosal resection) and cold snare polypectomy of medium-sized non-pedunculated colorectal polyps during outpatient colonoscopy. Objective. To study the results of hot snare polypectomy and cold snare polypectomy of 10—15 mm non-pedunculated colorectal polyps during outpatient colonoscopy. Material and methods. We retrospectively reviewed the medical records of 109 patients with 123 non-pedunculated colorectal polyps from 10 to 15 mm in diameter that were removed by hot snare polypectomy (65) or cold snare polypectomy (58) between January 2017 and December 2022 during outpatient colonoscopy. There was no significant difference (p>0.05) in gender and average age of patients, localization, average size, macroscopic and histological structure of colorectal polyps, en-bloc resection rate and R0 resection rate. Results. The complication rate was significantly higher in the hot snare polypectomy group than in the cold snare polypectomy group (12.70% vs. 2.17%, p<0.05). Conclusion. Cold snare polypectomy is as well effective and significantly more safe method of removing of 10—15 mm non-pedunculated colorectal polyps compared to hot snare polypectomy.
