title: [Ultrasonic diagnosis of pyloroduodenal stenosis].
abstract: The method and semeiotics of noninvasive ultrasonic diagnosis of pyloroduodenal stenosis are described. Seventy-six patients with duodenal ulcer and 13 patients with gastric ulcer were examined, and also 18 patients with gastric carcinoma and 24 healthy individuals. The echographic picture of an empty stomach in compensated pyloroduodenal stenosis did not differ from that in healthy persons, though study of the motor-evacuation activity of the stomach revealed intensified peristalsis and increased gastric half-evacuation period. In subcompensated pyloroduodenal stenosis the stomach contained fluid and the period of half-evacuation of its contents was sharply increased. All patients with decompensated pyloroduodenal stenosis had an increased volume of the stomach which contained much fluid and food remnants. Pyloric spasm was differentiated by means of the spasmolytics test. Patients with a marked periulcerous inflammatory infiltration must be kept under dynamic follow-up to evaluate the degree of the stenosis. Taking into consideration the peculiarity of the echographic picture of the pyloric part, the neoplastic character of the pyloroduodenal stenosis may be presumed with high precision.
