Relationship of Campylobacter pylori and duodenogastric reflux.

We have examined the relationship of Campylobacter-like organism (CLO) and duodenogastric reflux (DGR) in 107 patients with unoperated stomachs. Neither the extent of externally measured bile reflux nor the concentrations of bile acids or lysolecithin in the gastric fluid differed significantly in the groups with different numbers of CLO in the gastric mucosa. Our results suggest that DGR, in the quantities commonly present in unoperated stomachs, does not effect the presence of C. pylori in the gastric mucosa.
