title: Experimental antireflux intestinal valve.
abstract: A reflux-preventing valve was obtained by invaginating a 3.5 to 4.5 cm segment of small bowel into the distal lumen, after removing the seromuscular layers at both ends of the segment of bowel. Antiperistaltic pressure resistance, measured at regular intervals during 6 months, showed valves with competence equal or superior to the ileocecal valve. The blood supply to the intussuscepted segment must be carefully preserved.
