[Characteristics of the evacuatory function of the stomach when fat is added to the food].
In dogs with fistulas in fundal and antral parts of the stomach and in the duodenum, the influence of adding fat (margarine) to carbohydrate food (bread) on the stomach evacuation was studied. Progressive increase of fat (25, 50 and 75%) in the food stimuli delayed the stomach evacuation, the delay assuring no stability of caloric transport to the duodenum. Destroying of pyloric sphincter led to an acceleration of the stomach evacuation. The latter finding suggests that the pyloric sphincter plays a major role in the regulation of stomach emptying from the fat food.
