Abstract

Local recurrence after piecemeal endoscopic mucosal resection (EMR) is common and it is a major drawback of this technique. Thermal ablation of resection margins after EMR using snare-tip soft coagulation has been shown to decrease the risk of local recurrence in a randomized trial [1]. Hybrid argon plasma coagulation (hAPC) is an alternative ablation technique that can be used to perform margin ablation. Recent studies on hAPC for post-EMR margin ablation showed low rates of local recurrence.
