[The role of Treitz' ligament in regulating the evacuation of solid food from the duodenum]

In the chronic experiments on dogs by means of modified method of multiple drainage of the intestinal fistulas, the effect of the Treitz ligament transection on dynamics of solid carbohydrate food evacuation from the duodenum was studied. It was established that in the norm, evacuation from the duodenum was submitted to exponential law and depended on absolute quantity of food evacuated from the stomach. After the Treitz ligament transection, the evacuation through intestine had a non-exponential character. The operation led to disturbance in co-ordination between evacuatory function of the stomach and that of duodenum, and also had the depressive effect on intestinal emptying. The conclusion is made of the functional role of the Treitz ligament as active regulator of solid food evacuation from the duodenum.
