Histopathological effects of electrosurgical interventions in an in vivo porcine model of colonic endoscopic mucosal resection

Endoscopic mucosal resection (EMR) in the colon has been widely adopted, but there is limited data on the histopathological effects of the differing electrosurgical currents (ESCs) used. We used an in vivo porcine model to compare the tissue effects of ESCs for snare resection and adjuvant margin ablation techniques.Standardised EMR was performed by a single endoscopist in 12 pigs. Two intersecting 15 mm snare resections were performed....
