|Colon Disease Gastric Disease||Procedure: Tissue Access and Resection System||Not Applicable|
The subject will already be scheduled for segmental colectomy or gastrectomy.
The colectomy or gastrectomy specimen will be prepared on a side table for an ex vivo endoscopic procedure. The ends of the stomach or colon, if not already stapled closed will be ligated to allow for insufflation. The endoscope will be placed into the excised organ and the SuMO System devices will be deployed away from any areas of excised pathologic tissue, so as not to disrupt the pathologist's evaluation of the excised tissue. The specimen will then be opened and grossly examined for the actual completeness of the submucosal pocket and resection. Mucosal and muscular wall disruptions will be assessed. Again, no interference in the underlying pathology will be performed. If sufficient specimen is present, the SuMO procedure may be repeated on the same specimen.
Following the performance of the EMR by the SUMO balloon system on the ex vivo colon specimen, both the resected piece of tissue and the site of resection will be evaluated pathologically by H and E staining. Specifically, the depth of resection in the ex vivo colon specimen will be determined. In addition, the level of dissection on the removed piece of mucosa will also be identified.
During this procedure still images or a video recording maybe captured, however all images will be taken of the removed specimen. There will not be any patient identifiers on any of the images or DVD's taken during the procedure.
No clinical follow up is required, as the treated area will have already been resected and there is no risk to the patient.

|Experimental: SUMO Tissue Access and Resection System||
Procedure: Tissue Access and Resection System
This feasibility trial will assess the effectiveness of SuMO System to create a submucosal pocket and resect the overlying mucosa in excised human colonic or gastric tissue
Other Name: SUMO Tissue Access and Resection System
- Evidence of the ability of the SUMO device to create a submucosal pocket and resect the overlying mucosa in human colon or stomach. [ Time Frame: (day one)The colon or stomach tissue is evaluated in the Operating Room immediatley following excision. Subjects are not followed after using the excised tissue in the operating room. ]Assess the feasibility of the SuMO device for creation of a submucosal pocket and resecting the overlying mucosa in a segment of excised human colon or stomach.
