[Correlation among endoscopic, histological, and microbiological findings in gastroduodenal pathology associated with Helicobacter pylori].

We studied 152 patients referred for endoscopy of the upper gastrointestinal tract. Samples of the gastric mucosa and fundus were taken and processed for microbiological and histological study using conventional methods. Acute lesions to the gastrointestinal mucosa were those most frequently observed in endoscopy (28.3%). The overall prevalence of chronic gastritis was 90.8%. The prevalence of infection by H. pylori was 59.8%. All patients in which gastric ulcer or malignant lesions were observed had some kind of chronic gastritis. Duodenal ulcer was the lesion with the highest prevalence and statistical significance with respect to the existence of H. pylori infection. There was a highly significant correlation between H. pylori gastric colonization and lesions of the diffuse antral type and with gastric activity. The significant correlations among the endoscopic, microbiological and histological findings are discussed.
