[Cystic polyposis of the stomach (fundic gland polyps)--relationship to the absence of Helicobacter pylori infection and a therapy with drugs suppressing gastric acidity].
BACKGROUND
Cystic gastric polyps (fundic gland polyps) have been diagnosed relatively frequently in recent years. The aim of the study was to assess their incidence and relation to possible etiological factors reported in the literature.


METHODS
Over a 5 year period, we have endoscopically and histologically proved cystic polyps in 32 patients. All were examined for Helicobacter pylori infection using either the invasive rapid test, histological examination or 13C urea breath test.


RESULTS
Cystic gastric polyps were found significantly more frequently in women (27) than in men (5). All patients were treated with long-term medication suppressing gastric acidity (26 patients with proton pump inhibitors, and 6 with H2 receptor blockers). Helicobacter pylori infection was not detected in either of the patients with proven cystic gastric polyps. Cystic gastric polyps have not the typical clinical picture and they are largely found incidentally during gastroscopic examination, especially in patients with reflux esophagitis or functional dyspepsia.


CONCLUSIONS
The results confirm evidence in the literature of a close relation between cystic gastric polyps and intensive suppressive treatment of gastric acidity, particularly in combination with the current absence of Helicobacter pylori infection. Precise explanation of this relation and the etiology of cystic gastric polyps is still missing. Important is the fact that the literature reports do not indicate a risk of malignant transformation.
