GASTRIC SECRETORY TEST WITH PENTAGASTRIN. STIMULANT REPORT OF A MULTICENTER STUDYIN PATIENTS WITH VARIOUS GASTRODUODENAL DISEASES

Pentagastrin stimulated gastric secretory tests (PSGST) were performed in 31 normal subjects and 569 patients with various gastro- duodenal diseas.es The mean basal acid output (BAO) and peak acid output (PAO) were higher in patients wi.th duodenal ulcer and combined ulcers, lower in patients with chronic atrophic gastritis and gastric carcinoma as compared with normal;s. The PSGST results in patients with chronic superficial gastritis and gastric ulcer were similar to those in normal subjects. Pa- tients with stomal ulcer had a higher PAO than those without stomal ulcer. The clinical value and significance of the test are discussed.
