The success of gastric bypass probably depends on factors other than merely the restrictive size of the gastric pouch and outlet. Postoperative dumping and a mild degree of malabsorption derived from the redirection of intestinal contents contribute to long-term success. Thus, gastric bypass combines some elements of both malabsorptive and gastric restrictive procedures.
