[Clinico-morphologic characteristics of reflux gastritis in patients with peptic ulcer before and after surgical intervention].

Experimental and clinical studies convincingly indicate that duodenal-gastric reflux may provoke the development of reflux gastritis with a characteristic clinico-morphological complex. However, the clinical picture of reflux gastritis in patients with stomach ulcer is not always typical, is frequently masked by the underlying disease and therefore is difficult for diagnosis. The necessity of the use of the laboratory and instrumental methods arises, with an obligatory histological examination. Morphological studies indicate the existence of certain characteristic signs of reflux gastritis, the detection of which makes this diagnosis valid.
