Dynamics of atrophic gastritis in male and female subjects after partial gastric resection -- an evaluation by stochastic analysis.

Forty-two subjects (33 male and 9 female) were examined 17 to 18 years after partial gastrectomy due to gastric or duodenal ulcer, with regard to morphological state of gastric body mucosa, specimens obtained by direct gastroscopy technique being evaluated by our scoring system. Our stochastic analysis was applied to the findings to obtain the "age-adjusted score' (AAS), representing the degree of progression of chronic gastritis with reference to a random population, independent of the subject's age. Higher susceptibility of males than females to progressing chronic gastritis, and higher than that of both males and females of the random population, was noted. The atrophic changes in males after gastrectomy showed no dependence on age.
