Abstract: A generally rectangular flexible wrap panel having longitudinally spaced inwardly tapering and outwardly opening opposite side marginal notches formed therein intermediate its opposite ends is provided and the outer margin of a radially split annular flexible yoke panel is secured across one end of the wrap panel. Opposing edges of the wrap panel defining the notches are then overlapped and secured together to form darts in the wrap panel and the wrap panel is placed along the greater curvature of the stomach with the collar panel registered with the esophagogastric junction. The side marginal edges of the wrap panel are then wrapped about the stomach toward the lesser curvature, overlapped and sutured together and the circumferential ends of the yoke panel are overlapped and sutured together about the esophagogastric junction and the end edges of the collar panel are sutured together about the esophagus.
