Reflux gastritis and dysplasia.

In order to evaluate if duodenogastric reflux (DGR) is associated with a different frequency of gastric dysplasia in comparison with the absence of DGR. 40 dyspeptic patients were studied. Nineteen of them had scintigraphic evidence of the DGR, while in 21 DGR was absent. The obtained results demonstrate a higher frequency of antral gastritis in presence of DGR, while fundic gastritis is similarly represented in the two studied groups. Dysplasia of the mild type is observed in 1 case of fundic atrophic gastritis without DGR and in 3 cases of atrophic gastritis with DGR (1 in fundus and 2 in antrum), thus demonstrating that reflux gastritis is not strictly correlated with dysplasia.
