Abstract

The purpose of this report is to present a comparison of findings on gastric secretion when a tubeless method with azure A resin compound (Diagnex Improved) and an intubation method with histamine stimulation are both employed in the same patient. In 1950. Segal, Miller, and Morton¹described a method for determining the presence or absence of free hydrochloric acid in the stomach without the use of intubation. This procedure consisted of the oral administration of an ion-exchange resin coupled with quinine. Although this technique was reliable,²it was not widely adopted because of the complicated laboratory facilities necessary in analyzing the quinine compound excreted in the urine. The subsequent development of a stable carboxylic resin indicator with azure A for the detection of free gastric hydrochloric acid³has provided a method that has proved to be simple and practical. This determination involves a displacement of the azure
