Zollinger–Ellison syndrome (ZES) is a Gastrinoma which is a neuroendocrine tumor that secretes Gastrin; resultant hypergastrinemia causes gastric acid hypersecretion. This leads to growth of gastric mucosa, increase in number of Parietal cells and proliferation of gastric ECL cells. Most Gastrinomas are present in duodenum (50-70%), pancreas ( 20-40%) and other intraabdominal site.
