&NA;Problems associated with the nipple valve of the continent ileostomy continue to be a major obstacle, frequently necessitating reoperation, with ongoing incontinence persisting in some patients. We have constructed a continent ileostomy in a dog using a three‐loop reservoir, continence being maintained by placing a porcine aortic valve in the efferent loop of the reservoir, obviating the need for the nipple valve. A detailed description of the technique is given. Possibilities for its application to particular clinical problems are discussed.
