A critical analysis of the gastric secretory response of patients with duodenal ulcer in dependence of their age and duration of complaints.

The different parameters of the basal and maximal gastric secretory responses were measured in 120 patients with duodenal ulcer. The correlations between the different gastric secretory parameters [volume, H+ concentration, basal acid output (BAO), maximal acid output (MAO), maximal acid output-basal acid output, basal acid output . maximal acid output X 100] were studied in these patients, in dependence of their age and duration of complaints. A positive and mathematically significant correlation was found between the following parameters: 1. age of patients and H+ concentration of gastric basal secretion (r = 0.326; n = 120; P less than 0.001); 2. age of patients and basal acid output (r = 0.200; P less than 0.05); 3. duration of complaints and volume of gastric basal secretion (r = 0.186; P less than 0.05); 4. duration of complaints and basal acid output (r = 0.237; P less than 0.05); 5. age of patients and BAO . MAO-1 X 100 (r = 0.216; P less than 0.05); 6. duration of complaints and BAO. MAO-1 X 100 (4 = 0.197; P less than 0.05); 7. volume of gastric maximal and basal secretory response (r = 0.398; P less than 0.001); 8. H+ concentration of gastric maximal and basal secretory response (r = 0.480; P less than 0.001); 9. MAO and BAO values (r = 0.521; P less than 0.001); 10. H+ output and H+ concentration of gastric basal secretory response (r = 0.620; P less than 0.001); 11. H+ output and volume of gastric basal secretory response (r = 0.779; P less than 0.001); 12. H+ concentration and volume of gastric maximal secretory response (r = 0.298; P less than 0.01); 13. H+ output and H+ concentration of gastric maximal secretory response (r = 0.720; P less than 0.001); 14. H+ output and volume of gastric maximal secretory response (r = 0.802; P less than 0.001). A negative and mathematically significant correlation was observed between the values of BAO . MAO-1 X 100 and of MAO - BAO (r = 0.435; P less than 0.001). It has been concluded 1. duodenal ulcer disease protects the human gastric fundic mucosa against "senile decay"; 2. the changes of gastric basal and maximal secretory responses, induced by duodenal ulcer, do not supply a pathological base for gastric surgery in patients, on dependence on their ages and duration of complaints.
