Characteristics of reflux gastritis.
The amount of postprandial duodenogastric bile reflux was correlated with detailed histologic findings in the stomachs of 107 patients with dyspepsia. The reflux was associated with infiltration of mononuclear leukocytes, neutrophilic granulocytes, and eosinophilic granulocytes and with foveolar hyperplasia in the gastric mucosa. No significant association with intestinal metaplasia emerged. Our results suggest that postprandial duodenogastric bile reflux is characterized by superficial inflammatory changes in the gastric mucosa.
