Gastric neuroendocrine neoplasms: a primer for radiologists.

Abdom Radiol (NY) 2022 Apr 12. Epub 2022 Apr 12.

Department of Radiology, Michigan Medicine, University of Michigan, 1500 East Medical Center Drive, B1D502, Ann Arbor, MI, 48109, USA.

Gastric neuroendocrine neoplasms are uncommon tumors with variable differentiation and malignant potential. Three main subtypes are recognized: type 1, related to autoimmune atrophic gastritis; type 2, associated with Zollinger-Ellison and MEN1 syndrome; and type 3, sporadic. Although endoscopy alone is often sufficient for diagnosis and management of small, indolent, multifocal type 1 tumors, imaging is essential for evaluation of larger, high-grade, and type 2 and 3 neoplasms.

Gastrinoma and Zollinger Ellison syndrome: A roadmap for the management between new and old therapies.

World J Gastroenterol 2021 Sep;27(35):5890-5907

Division of Gastroenterology and Center for Autoimmune Liver Diseases, Department of Medicine and Surgery, University of Milano-Bicocca, Monza 20900, Italy.

Zollinger-Ellison syndrome (ZES) associated with pancreatic or duodenal gastrinoma is characterized by gastric acid hypersecretion, which typically leads to gastroesophageal reflux disease, recurrent peptic ulcers, and chronic diarrhea. As symptoms of ZES are nonspecific and overlap with other gastrointestinal disorders, the diagnosis is often delayed with an average time between the onset of symptoms and final diagnosis longer than 5 years. The critical step for the diagnosis of ZES is represented by the initial clinical suspicion. Read More

Benign Oesophageal Stricture and Chronic Diarrhoea As Atypical Presenting Symptoms of an Advanced Metastatic Pancreatic Gastrinoma: A Case Report and Review of Literature.

Cureus 2021 Jul 23;13(7):e16593. Epub 2021 Jul 23.

Gastroenterology, United Lincolnshire Hospitals National Health Service (NHS) Trust, Boston, GBR.

Gastrinoma or otherwise known as Zollinger-Ellison syndrome is characterised by hypersecretion of gastrin and gastric acid leading to the formation of recurrent atypical ulcers along the upper gastrointestinal tract. It is extremely difficult to diagnose during an acute presentation both due to its rarity and its lack of pathognomonic symptoms. Its symptoms range from mild to severe to life-threatening and often get mistaken for a different condition such as viral gastroenteritis as seen in our case report. Read More

Enterochromaffin-like Cell Hyperplasia-Associated Gastric Neuroendocrine Tumors May Arise in the Setting of Proton Pump Inhibitor Use.

Arch Pathol Lab Med 2022 03;146(3):366-371

From the Departments of Pathology and Immunology (Rais, Chatterjee), Washington University in St. Louis, St. Louis, Missouri.

Context.—: Hypergastrinemia states such as achlorhydria from gastric mucosal atrophy or a gastrin-producing tumor in humans have been associated with the development of enterochromaffin-like (ECL) cell hyperplasia and gastric neuroendocrine tumors (GNETs). Whether drugs that can elevate serum gastrin levels, such as proton pump inhibitors (PPIs), can produce the same tissue effect is not known, and there is no concrete evidence linking the use of PPIs to GNETs outside animal models and case reports.

Postsurgical Presentation of Zollinger-Ellison Syndrome After Resection of Endometrioid Neuroendocrine Tumor.

ACG Case Rep J 2021 May 11;8(5):e00562. Epub 2021 May 11.

Division of Gastroenterology, Washington University School of Medicine in St. Louis, St. Louis, MO.

Zollinger-Ellison syndrome is a functional neuroendocrine tumor with inappropriate gastrin secretion and hyperchlorhydria causing severe peptic ulcer disease and chronic diarrhea. Although 70% of primary gastrinomas occur in the region of the duodenum, the diagnosis and localization of gastrinomas can be challenging because of small lesions that may arise functionally as lymph node metastases at initial presentation. We report a 76-year-old woman presenting with Zollinger-Ellison syndrome several months after surgical resection of endometrioid small cell neuroendocrine carcinoma and endometrioid adenocarcinoma.

Adverse Effects Associated with Proton Pump Inhibitor Use.

Cureus 2021 Jan 18;13(1):e12759. Epub 2021 Jan 18.

Internal Medicine, Dr Juan A. Fernández Hospital, Buenos Aires, ARG.

Proton pump inhibitors (PPIs) marked a before and after in the management of gastric acid-related disorders since their introduction to the market in 1989. Due to a novel, highly effective mechanism of action blocking the last converging step of gastric acid secretion by parietal cells and very few and mostly tolerable side effects, these drugs quickly displaced other pharmacological compounds such as H2 antagonists as the first treatment choice for peptic ulcer disease, gastroesophageal ulcers, Zollinger-Ellison syndrome, nonsteroidal anti-inflammatory drug-associated ulcers, and eradication of Helicobacter pylori, leading to an exponential increase in their prescription up to now. However, widespread PPI use has led to emerging evidence of long-term adverse effects not described previously, including increased risk of kidney, liver, and cardiovascular disease, dementia, enteroendocrine tumors of the gastrointestinal tract, susceptibility to respiratory and gastrointestinal infections, and impaired absorption of nutrients.
