title: [Non-ulcer dyspepsia syndrome].
abstract: In one thousand of 1500 examinees with nonulcerous dyspepsia the syndrome was due to chronic gastritis, duodenitis and gastroduodenitis, in five hundred of them it was attributed to probable dysfunction of the upper gastrointestinal tract. Morphological evidence of chronic gastritis activity is essential but not the only factor affecting the dyspepsia syndrome. Of importance are also motor dysfunctions: high intragastric and/or intraduodenal pressure, unbalance of intracavitary pressure parameters, gastroesophageal and duodenogastric refluxes. A significant contamination of antral mucosa with Helicobacter pylori aggravated dyspeptic manifestations.
