#267 Plasma Somatostatin: Gastrin Ratio Improves the Diagnosis of Gastrinoma
Introduction: Fasting gastrin alone is inadequate for diagnosis of gastrinoma. Diagnosis requires confirmation of low gastric pH. Low gastric pH is associated with increased numbers of D (somatostatin) cells.

#17 Diagnostic efficacy of the secretin stimulation test for the Zollinger-Ellison syndrome: an intra-individual comparison using different dosages in patients and controls
Introduction: The diagnosis of Zollinger-Ellison syndrome is suspected in patients with symptoms of gastric acid hypersecretion, i.e., peptic ulcer disease, malabsorption or diarrhea, or with elevated fasting serum gastrin levels. However, symptoms can be masked by the use of proton pump inhibitors and fasting serum gastrin values are not always conclusive. Therefore, the secretin stimulation test is advocated as the principal diagnostic tool to identify the Zollinger-Ellison syndrome.

#21 Peptide Receptor Radioligand Therapy (PRRT) is an Effective Treatment for the Long-Term Stabilization of Malignant Gastrinomas
Introduction: Gastrinomas represent a rare group of neuroendocrine tumors usually located in the duodenum or pancreas. They secrete gastrin, which is responsible for the clinical picture of severe acid-related peptic disease and diarrhea, known as the Zollinger-Ellison syndrome (ZES). While symptomatic control may be achieved with proton-pump inhibitors (PPIs) and somatostatin analogues (SSAs) treatment, little data is known regarding the possible anti-tumor effect of the peptide receptor radioligand therapy (PRRT) in gastrinoma patients.

#2284 The Association between Gastrin and Glucose Serum Concentration in Hypergastrinemic Patients with Gastric Neuroendocrine Tumors Type 1 and ECL-Cells Hyperplasia
Introduction: There is previous data demonstrating that elevated gastrin levels could exert some effect potentiating the glucose-induced insulin secretion.

#953 Comparison of Diagnostic Methods in the Evaluation of Pancreatic and Duodenal Gastrinomas
Introduction: Gastrinomas are neuroendocrine tumors, mainly located in the duodenum or the pancreas, that secrete gastrin and cause a clinical syndrome known as ZES.

#135 The importance of endoscopic ultrasound in detecting recurrent gastrinoma in a case of MEN 1
Introduction: Approximately 25-30% of patients have gastrinomas as part of the inherited syndrome Multiple Endocrine Neoplasia 1 (MEN 1). Gastrinomas occur in the pancreas, duodenum or peripancreatic lymph nodes. Diagnosis is made by clinical history, gastroscopy, and measurement of serum gastrin, gastric juice pH, CT scan, endoscopic ultrasound (EUS) and somatostatin receptor scintigraphy (SRS). Localization of gastrinomas in patients with MEN 1 is challenging due to their small size, frequent duodenal location, and multiplicity.

#283 Primary Lymph Node Gastrinoma: A Genuine Entity? Two Case Reports and a Review of the Literature
Introduction: The existence of primary lymph node gastrinoma has been proposed but is controversial. We report two cases (Case A - 37-year-old male, Case B - 43-year-old male) of apparent primary lymph node gastrinoma.

#830 The Predictive Value of Gastrin Levels for the Diagnosis of Gastric Enterochromaffin-like Cells Hyperplasia, in Patients with Hashimoto’s Thyroiditis
Introduction: Gastrin and chromogranin A (CgA) levels have been tested for the diagnosis of enterochromaffin-like cell hyperplasia (ECLH), in patients with type 1 diabetes and autoimmune atrophic gastritis but there are no data for patients with Hashimoto's thyroiditis (HT).
