Both Baylor St Luke's Medical Center and Mayo Scottsdale are considered endoscopic submucosal dissection (ESD) centers of excellence. The investigators at Baylor College of Medicine have previously reported our Esophageal ESD experience using the monopolar current knife. Moreover, the research team have previously reported on the clinical efficacy of the bipolar RFA knife during per-oral endoscopic myotomy (POEM) and colonic ESD. The goal of our study is to prospectively evaluate the efficacy, safety and feasibility of Esophageal ESD using a novel Bipolar-Current ESD device.
