<qa>  What is the SuMO system used to resect?This feasibility trial will evaluate the ability of the SuMO Tissue Access and Resection System Apollo Endosurgery, Austin, Texas. The SuMO System utilizes balloons to create a submucosal pocket and electrosurgical cutting device to resect the mucosa. The SuMO elevates the tissue from the underlying muscularis using a balloon to distend the submucosa, similar to what is currently performed with injectable saline in a standard EMR. After dissection of the lesion, a separate cutting device will be utilized to resect the tissue by cutting around the border of the targeted tissue. If needed, a standard loop snare will be used to complete the mucosal resection.
