[Use of echography in the diagnosis of gastroduodenal pathology in children].

The stomach and duodenum were examined by echography in 285 children with gastroduodenal pathology and in 206 healthy children. Evacuatory function of the stomach was assessed in accordance with the rate of evacuation from the stomach of an acoustic marker, raw egg yolk which was introduced into the stomach preliminarily filled with 5% glucose. The potentialities of echography have been demonstrated for gastritis, gastroduodenitis and peptic ulcer. Simultaneous examination of evacuatory function of the gallbladder in children with gastroduodenal pathology has revealed a tendency towards its increase.
