[Practical value of gastric intubation during peptic ulcer. Analysis of 410 cases, after Histalog stimulation]

This study was carried out in 410 subjects, collecting gastric fluid for one hour, after 15 minutes emptying and one hour, after 15 minutes emptying and one hour's study of basal secretion using, as stimulant, Histalog at a maximal dose of 2 mg/kg without exceeding 130 mg. The object of this statistical analysis was to determine the average figures and the standard deviations of the volumes of secretions, together with those of the output of hydrogen ions in 5 groups of subjects: controls (60), gastric ulcers (38), duodenal ulcers (200), patients suspected of duodenal ulcer (60) or affected by dyspeptic syndrome without radiological nor endoscopic lesions (52). In the normal subject, the hydrochloric acid output was situated between 5 and 27 mEq. The diagnosis of duodenal ulcer was very unlikely when secretion was less than 9 mEq in man and almost certain above 30 mEq.
