| Aims: We aimed to assess the safety of low-power pure cut hot snare polypectomy (LPPC HSP) which is expected to reduce delayed bleeding due to less thermal damage. Methods: Consecutive patients who underwent LPPC HSP for nonpedunculated colorectal neoplasms 10-14 mm at two institutions between December 2018 and March 2022 were included. A 10 or 15 mm SnareMaster Plus was used with either of the following modes; PureCut effect 1 10W (ESG-300), AUTO CUT effect 1 10 W (VIO300D), or AUTO CUT effect 0.4 (VIO3). Delayed bleeding rate of LPPC HSP was compared with historical control data of HSP based on previous meta-analysis. Results: A total of 339 patients with 410 lesions were identified. En bloc resection rate was 94.9%. Immediate bleeding requiring hemostasis occurred in 4 lesions. No perforations occurred. Delayed bleeding occurred in two patients, both required hospital admissions but were managed conservatively without hemostasis. Delayed bleeding rate was 0.6% per patient. LPPC HSP was associated with a 71.4% reduction in the risk of delayed bleeding compared to the historical control (2.1%), with a power of 80.8% using a 2-sided significance level of 0.05. Conclusions: Delayed bleeding rate of LPPC HSP for nonpedunculated colorectal neoplasms 10-14 mm was 0.6%, which may be lower than that of conventional HSP. |
