[A comparative assessment of gastric secretory function using a probe method and intragastric Ph-metry].

To compare informative value of probing and intragastric pH-metry, relevant examination was performed in 130 patients with chronic gastritis, 132 patients with noncomplicated peptic ulcer and 50 healthy subjects. pH values obtained with probing and intragastric pH-metry did not differ significantly in defects of gastric mucosa, superficial gastritis, peptic ulcer. In apparent atrophic gastritis intragastric pH-metry detected minimal secretion of H ions in all the patients, whereas probing failed to show it. Intragastric pH-metry is useful in recognizing duodenogastric reflux and decompensated acid stomach as shown by antral basal pH (below 2.0).
