H. Hammer demonstrated that dogs could survive with reversal of the entire duodenum.3 Up to that time the conclusions of F. P. Mall and William Halsted4 in 1896 that reversed intestinal segments ultimately caused death in experimental animals through acute or chronic obstruction had remained unchallenged in the literature. In 1962, L. D. Gibson5 applied Hammer's suggestion6 clinically by reversing a 7.5-cm jejunal segment in a patient who had had a massive intestinal resection. The result was very encouraging and established the use of short reversed intestinal segments in people following
