Abstract
The morphological changes in the gastric mucosa in the presence of duodenogastric reflux and refluxesophagitis and their connection with the presence of Helicobacter pylori (HP) infection are studied. The endoscopic and histological examination of the stomach antral part was performed in 1251 patients with different gastroduodenal pathologies. HP was diagnosed by histological and real-time PCR methods. Among patients with different gastroduodenal pathologies the frequency of H. pylori infection was 77.9 %. Duodenogastric reflux was detected in 23.9 % of patients. In the presence of duodenogastric reflux, we have found a decrease in the risk of duodenal ulcer by a factor of 2.5, thus duodenogastric reflux may protect against the development of duodenal ulcer. In patients with duodenogastric reflux in the presence of H. pylori infection, significant differences from the group uninfected of Helicobacter pylori were found in the metaplasia frequency. A significant increase in the frequency of foveolar hyperplasia among patients with duodenogastric reflux was revealed. The prevalence of reflux-esophagitis in the study group was 8.3 %. No increased risk in reflux-esophagitis was observed either in the HP-positive or HP-negative cases. According to our finding, duodenogastric reflux was characterized by foveolar hyperplasia and metaplasia. We suggest that the presence or absence of H. pylori does not affect reflux-esophagitis.
