An apparatus, system, and method for covering an anastomosis are disclosed. The apparatus includes a resilient flexible patch having a diameter that is greater than the diameter of an anastomosis. A opening is formed in the patch. The opening has a diameter that is less than the diameter of the anastomosis. The system further includes a joining element to attach the patch to tissue adjacent to the anastomosis. At least one hole is formed around the perimeter of the patch. The at least one hole is to receive the joining element therethrough. The method includes inserting a resilient flexible patch having a diameter that is greater than the diameter of an anastomosis through a working channel of an endoscope, locating the patch adjacent to the anastomosis, and attaching the patch to tissue adjacent to the anastomosis using a joining element.
