[Duodenogastric reflux and functional state of the stomach and duodenum]

As many as 91 children with different gastroenterological diseases were examined. 57.8% of the children manifested the duodenogastric reflux. Acid-forming function of the stomach appeared normal or elevated. Electrogastrography showed the predominance of the hyperkinetic and normokinetic curve types. Manometry of the stomach and duodenum often demonstrated duodenal hypertension with a reflux of the duodenal contents to the stomach. The incidence of the duodenogastric reflux was not dependent on the patients' age, sex or disease standing. Alterations in the gastric and duodenal mucosa may be both the cause and consequence of the gastroduodenal reflux.
