A Method of Intestinal Cannulation for Collection and Return of Digesta

Abstract

An intestinal re-entrant cannulation technique was devised which did not necessitate gut transection. The technique provides for the total collection and return of digesta, but restores a comparatively uninterrupted flow of digesta between collection periods. The technique involves the displacement of a short section of intestine to a subcutaneous site between two simple T-shaped cannulae. The procedure has been shown to cause some disturbance to the flow of digesta when not in use, but this was less than when a divided intestine was connected by rigid cannulae.
