ENETS Consensus Guidelines for the Management of Patients with Digestive Neuroendocrine Neoplasms: Functional Pancreatic Endocrine Tumor Syndromes

Gastrinomas are neuroendocrine neoplasms, usually located in the duodenum or pancreas, that secrete gastrin and cause a clinical syndrome known as Zollinger-Ellison syndrome (ZES). ZES is characterized by gastric acid hypersecretion resulting in severe peptic disease (peptic ulcer disease (PUD), gastroesophageal reflux disease (GERD)) In this section, ZES due to both duodenal and pancreatic gastrinomas will be covered together because clinically they are similar Specific points related to gastrinomas associated with the genetic syndrome of Multiple Endocrine Neoplasia type 1 (MEN1) (25% of cases) will also be mentioned
