[Correlations between gastric erosions and duodenal ulcer. Endoscopic study].

123 varioliform, 105 aphthous and 48 haemorrhagic flat erosions were noted in 2618 gastroduodenoscopies. A high incidence of erosions were associated with duodenal ulcer (43% of duodenal ulcers), especially in varioliform types and antrally. It is suggested that antral varioliform erosions form an integrating part or even the sole expression of an ulcer, and thus be seen as "sentinels" of an existing, potential or prior duodenal ulcer. Based on statistics, this view is supported by the maximum stimulus acidograms, which show that the PAO in antral varioliform erosions form an integrating part or even the sole expression of an ulcer, and thus be seen as "sentinels" of an existing, potential or prior duodenal ulcer. Based on statistics, this view is supported by the maximum stimulus acidograms, which show that the PAO in antral varioliform erosggested that antral varioliform erosions form an integrating part or even the sole expression of an ulcer, and thus be seen as "sentinels" of an existing, potential or prior duodenal ulcer. Based on statistics, this view is supported by the maximum stimulus acidograms, which show that the PAO in antral varioliform erosion without duodenal ulcer is within the range for duodenal patients. The employment of PAO is thus proposed in all cases of isolated antral varioliform gastric erosion, particularly in the absence of other possible causes.
