Abstract

BACKGROUND AND AIMS: Conventional EMR using a hot snare is the standard of care for resection of large (≥20 mm) nonmalignant sessile colonic polyps. Serious adverse events are predominantly because of electrocautery. This could potentially be avoided by cold snare piecemeal EMR (CSP-EMR). This study aimed to evaluate the safety and efficacy of CSP-EMR of sessile colonic polyps sized ≥20 mm. METHODS: All cases of CSP-EMR at 5 Australian academic hospitals for sessile polyps ≥20 mm over a 2-year period, from January 2016 to December 2017, were identified retrospectively. Efficacy was defined as the absence of residual or recurrent polyp tissue during the first surveillance colonoscopy (SC1) an..
