Feasibility of Translumenal Endoscopic Omental Patch Closure of Perforated Viscus

This study is being done to see if a new approach to repair perforated ulcers in the stomach (holes in the stomach) or the first part of the intestine is possible. Traditionally, either open operations (large single incision) or laparoscopic operations (multiple small camera-guided incisions) have been used to repair perforated ulcers. Over the last ten years, some surgeons have used endoscopic equipment to assist them with performing the procedure. It is unknown if perforated ulcer repair can be done using an endoscope as the main instrument (a flexible tube with a video camera inserted into the stomach through your esophagus) to "patch" or plug the perforation. We will patch the perforation using a standard method which uses tissue from outside the stomach. A laparoscopic camera will also be used to assist our view. This study is intended to be a feasibility study to demonstrate the endoscopic technique can be safely performed Hypothesis: The primary outcome is successful completion of the procedure.
