Primary lymph node gastrinoma has been defined as gastrin-producing tumor present in lymph nodes and predominantly found in well-defined anatomical region known as gastrinoma triangle. They are usually localized preoperatively with imaging, and their surgical resection results in long-term relief. The authors report a case of unresectable primary lymph nodal gastrinoma with liver metastases in a 14-year-old adolescent boy with proven histopathology detected on Ga-DOTANOC whole-body PET/CT scan followed by preoperative multiple Lu-DOTATATE cycles for cytoreduction.

Neuroendocrine tumors (NETs) of cystic duct are extremely rare, accounting for less than 2% of NET cases. The association of biliary tree NET and multiple endocrine neoplasm type 1 (MEN1) are even more rare. In this report, we described a case of a 65-year-old woman who was referred to our neuroendocrine outpatient clinic to investigate MEN1 after an incidental diagnosis of gastrinoma. Read More

Background: Multiple endocrine neoplasia type 1 (MEN1) is a rare, autosomal dominant inherited syndrome caused by mutations in the MEN1 tumor suppressor gene. The diagnosis is defined clinically by the presence of 2 or more primary MEN1 tumors (parathyroid, anterior pituitary, and pancreatic islet). We describe the case of a patient who presented with classic history and imaging findings for MEN1. Read More

This article reviews the role of surgical and medical management in patients with Zollinger-Ellison syndrome (ZES) due to a gastrin-secreting neuroendocrine tumor (gastrinoma). It concentrates on the status at present but also briefly reviews the changes over time in treatment approaches. Generally, surgical and medical therapy are complementary today; however, in some cases, such as patients with ZES and multiple endocrine neoplasia type 1, the treatment approach remains controversial.

SASI (selective arterial secretin injection) is a form of ASVS (arterial stimulation and venous sampling) used to localize pancreatic gastrinomas. This report aims to review the protocol for SASI and demonstrate its utility in localizing functional and nonfunctional gastrinomas. Even if a patient has a pancreatic mass and a laboratory profile fitting a specific endocrine syndrome, these may or may not be associated as has been previously demonstrated with adrenal vein sampling.

Gastrin acts physiologically as a gut hormone to stimulate acid secretion after meal and as a cell-growth factor of oxyntic mucosa. Increase in serum gastrin level happens under various conditions including Zollinger-Ellison syndrome, antral G cell hyperplasia, autoimmune gastritis, atrophic gastritis, renal failure, vagotomy, Helicobacter pylori infection and acid suppressive therapy. As acid suppressive therapy causes hypergastrinemia, the association between acid suppressive therapy and gastric neuroendocrine cell tumor (NET) has been discussed during the past 30 years.

Aims: In exocrine pancreatic insufficiency (EPI), the quantity and/or activity of pancreatic digestive enzymes are below the levels required for normal digestion, leading to maldigestion and malabsorption. Diagnosis of EPI is often challenging because the characteristic signs and symptoms overlap with those of other gastrointestinal conditions. Additionally, there is no single convenient, or specific diagnostic test for EPI. Read More

Neuroendocrine neoplasms of the digestive system (GEP-NEN) represent a heterogeneous group of malignancies with various clinical presentation and prognosis. GEP-NENs can potentially affect all organs of the gastrointestinal tract; characteristically they share the biological property to produce and secrete peptides and neuroamines. About 30% of GEP-NENs are hormonally active and can cause specific clinical syndromes. Read More

Purpose: Analyze the role of somatostatin analogues (SSAs) in the treatment of sporadic and MEN1-related gastrinomas, trying to define whether recent trials have changed the landscape of gastrinoma therapy.
Methods: We evaluate the rationale of SSA use in the treatment of gastrinomas, summarize the current literature concerning the effect of SSAs on the control of Zollinger-Ellison syndrome (ZES) and gastrinomas tumor progression and discuss their role in the most recent guidelines.
Results: The medical treatment of gastrinoma and related ZES is aimed at controlling acid hypersecretion and tumor progression, in inoperable patients. Read More

Zollinger-Ellison syndrome (ZES) is a clinical syndrome characterized by gastric acid hypersecretion due to the ectopic secretion of gastrin by a gastrinoma, a neuroendocrine tumor (NET) which mostly develops in the duodenum and in the pancreas. This syndrome was first described by Zollinger and Ellison in 1964; if left untreated, ZES can lead to multiple complications mainly due to gastric hypersecretion and some patients can suffer from the complications of an advanced metastatic disease. Although its clinical features are considered typical, the diagnosis of ZES is often challenging for the clinician. Read More

Zollinger-Ellison syndrome (ZES) results from an ectopic gastrin-secreting tumor leading to peptic ulcer disease, reflux, and chronic diarrhea. While early recognition portends an excellent prognosis with >80% survival at 15 years, symptoms are often nonspecific making the diagnosis difficult to establish. Diagnosis involves a series of tests, including fasting gastrin, gastric pH, chromogranin A, and secretin stimulation. Read More

Background: Zollinger-Ellison syndrome is a rare cause of tumoral hypergastrinemia; 1 of 5 patients with this syndrome also has multiple endocrine neoplasia type 1.

Background: The introduction of proton pump inhibitors (PPIs) into clinical practice has revolutionized the management of acid-related diseases. Studies in primary care and emergency settings suggest that PPIs are frequently prescribed for inappropriate indications or for indications where their use offers little benefit. Inappropriate PPI use is a matter of great concern, especially in the elderly, who are often affected by multiple comorbidities and are taking multiple medications, and are thus at an increased risk of long-term PPI-related adverse outcomes as well as drug-to-drug interactions.
