Prepyloric erosions: an entity of its own among erosive gastric lesions. A morphologic and dynamic study of gastric mucosa in patients with gastric erosions.
The morphology and dynamics of the gastric mucosa were examined in 130 patients with gastric mucosal erosions by using mathematical methods based on stochastic principles. The results were compared with those of controls representative of the general population. The progression of antral gastritis was less rapid in erosion patients than in the controls (p less than 0.001), but body gastritis increased with age, as expected. In patients with prepyloric erosions body gastritis showed less rapid progression with age than in the controls (p less than 0.01) or in other erosion patients (p less than 0.05). Antral gastritis increased, as in the controls, and more rapidly than in other erosion patients (p less than 0.01). The preservation of the body mucosa in patients with prepyloric erosions despite ageing is similar to that seen in patients with duodenal ulcer disease, suggesting a common acid-related pathogenesis.
