[Detection of Campylobacter pylori in gastric mucosa--relation to gastroscopy findings and degree of gastritis].

In 862 unselected gastroscopies we could confirm the high percentage of campylobacter pylori infection in the antral gastric mucosa strongly associated with chronic superficial gastritis and active inflammatory signs. Significant correlation with age concerned the normal findings only. In patients with duodenal ulcers we found in 91% gastritis and in 88% campylobacter pylori in antral mucosa. A small group with duodenal ulcers was campylobacter pylori-negative as well as without gastritis signs. Comparing the antrum and corpus gastric mucosa (250 pat.) the antral mucosa was representative for the whole stomach in view of gastritis and campylobacter pylori test, sufficiently for practical use. Between the test methods (culture, urease, microscopy) we favoured the microscopic test.
