In a multicenter, multinational study, retrospectively obtained data for 379 patients showed 615 sessile serrated lesions ≥10 mm in size resected by cold snare polypectomy without submucosal injection. The mean polyp size was 13.7 mm, with 19.8% of resected lesions ≥20 mm and 2.9% ≥30 mm.
There were no significant adverse events. At follow-up of 23.4 (SD, 11.6) months, the rate of residual/recurrent lesions was 7.8%.
