Abstract
The difficulties in using ileal fistulation for digestion studies in pig were related. A comparative analysis of the clinical and physiological data collected on 11 pigs with ileal reentrant fistula (50-100 or 150 cm proximal to the ileo cecal junction), with ileo-cecal fistula, or with ileostomy, led to attribute the difficulties, for use of the reentrant fistulae, to a primitive motor disturbance. On this basis various data of the physiology of the ileo cecal junction were reviewed, suggesting that this junction was a true ileo-cecal sphincter. The distal ileum fitted with reentrant canulae could be the origin of an intestino-ileo-cecal reflex leading to the closure of the ileo-cecal sphincter, with some atony of adjacent intestinal areas.
