[Chronic gastritis and the presence of Helicobacter pylori in patients with non-ulcerative dyspepsia].

After definition in the group of the non ulcer dyspepsia (NUD) can be counted all those patients at whom beside the dyspeptical complaints, the radiological and endoscopical examinations didn't show ulcerative changes. The authors made biopsy 550 times on the occasion of 1390 gastroscopical examination (39.5% of the cases). The histological examination showed chronic gastritis in 372 cases (26.7% of all the examinations, 67.6% of the histological examinations). At this group of patients the dyspeptical complaints gave the principal indication of gastroscopical examination. Also it was examined the presence of dysplasia and intestinal metaplasia beside the different severity grade of chronic gastritis. The presence of Helicobacter pylori (Hp) was examined by histological methods. Hp positivity was noticed in 16.4% in the upper group. The authors made Hydrogen-breath examinations in 34 cases between patients with NUD. The results of Hydrogen-breath examinations also raise the multifactorial nature of the NUD. On the basis of examinations chronic gastritis and CP infection can form subdivisions in the heterogenic group of patients with NUD. For exacter judgement of Hp pathogenicity are needed further and wide-spread examinations. The authors would like to call the attention to the indispensability of the biopsy during the gastroscopical examination.
