Campylobacter pylori in esophagus, antrum, and duodenum. A histological and microbiological study

Abstract

Two hundred forty-six patients with a wide range of upper gastrointestinal tract disorders were investigated for the presence of Campylobacter pylori infection in esophagus, gastric antrum, and duodenum. C. pylori was identified in 52% of patients in at least one site, and microbiological and histological techniques were used to exclude the presence of the organism. Esophageal infection was not significant and is probably due to reflux. Antral C. pylori was significantly associated with active gastritis and active duodenitis and is possibly pathogenic.
