Significance of Gastric Analysis with Particular Reference to the Diagnosis of Zollinger-Ellison Syndrome

Various criteria in gastric analysis currently used for the diagnosis of the Zollinger-Ellison syndrome were assessed in cases of endoscopically normal gastric mucosa, gastric ulcer and duodenal ulcer. New criteria consisting of BSV>350ml/hr, BAO>25mEq/hr, MAO>60mEq/hr, and BAO/MAO>0.7 were proposed to differentiate the Zollinger-Ellison syndrome and peptic ulcer.
