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

For snare resection, MCC and LPCC did not produce significantly different tissue effects. The submucosal injectate may protect the underlying tissue, and technique may more strongly dictate the depth and extent of final injury. For margin ablation, APC was less uniform and complete compared with STSC.
