[Duodenogastric reflux in patients with functional dyspepsia].

In 66 patients with manifestations of functional dyspepsia and in nine volunteers duodenogastric reflux was studied by the cholangio-scintigraphic method. The results of the study were compared with the presence of the symptoms and sings and their intensity expressed in degrees, and with histopathological changes of gastric mucosa. In the symptomatic group the incidence of reflux was 42.4%. No reflux was found in the group of healthy volunteers. No relationship was demonstrated between duodenogastric reflux and the intensity of dyspeptic manifestations, nor between the reflux and the intensity of inflammatory changes in gastric mucosa.
