[Gastric acidity in a double ulcer (of the stomach and duodenum)]

Gastric salt-acid secretion was studied in three comparative patient groups with gastric ulcer, endoscopically confirmed, combination of gastric and duodenal ulcers. In the patients with double localization of the ulcer (stomach and duodenum) - hyperacidity was determined after pentagastrin stimulation. Acid-salt secretion was higher than that of the patients with gastric ulcer and was close to the secretion of those with duodenal ulcer, being but with a high standard deviation, necessitates consideration to be given to each concrete case of treatment. No discrepancy in the volume of gastric secretion before meals was established, thus impugning the role of pylor stasis in the genesis of secondary gastric ulceration. The incidence of atrophic gastritis in case of gastric and double ulcer is almost identical, hence attention is paid to the duodeno-gastric reflux as an eventual cause for damaging gastric mucosa with its successive ulceration in the patients with duodenal ulcer of many years. That is the reason, drugs enhancing the resistance of gastric mucosa as well as methoclopramid intake are proposed additionally to the drugs, neutralizing or blocking the gastric acid-salt secretion.
