[Electric activity of the proximal part of the digestive tract in the normal state and after pyloroplasty and transsection of the ligament of Treitz in dogs].
It is shown that the normal amplitude-frequency characteristics of the duodenojejunal flexure differ from those of the duodenum. After pyloroplasty, the electrical activity of the antrum do not change. At the region of the duodenojejunal flexure, the intensification of the electrical activity, increase in the amplitude, frequency of the slow wave and peak potentials occur. Supplementation of pyloroplasty with transection of the Treitz ligament led to suppression of the electrical activity of the antrum and duodenojejunal flexure. A conclusion about the close functional interrelation between the pylorus and duodenojejunal junction has been drawn.
