Zollinger Ellison Clinical Presentation

G-cell ECL cell Parietal Acid Gastrin Histamine - 20% Hepatobiliary Source: Enteroendo-crine cells Gas-trinoma cells 70% Duodenum Clinical manifestations and diagnosis of Zollinger-Ellison syndrome (gastrinoma) EpidemiologyPrevalence is 0.1 to1% of PUD.The peak age prevalence is 20- 50.Males are twice as likely as females to be diagnosed with Z-E.Gastrinomas can be either sporadic or associated with multiple endocrine neoplasia type 1.Approximately 80% of patients have the sporadic form although somatic (acquired) mutations in the MEN1 gene are observed-commonly in sporadic gastrinomas. Source: Enter-oendocrine cells Gastrinoma cells The gastrinoma triangle is formed by a line joining the confluence of the cystic and common bile ducts (A) superiorly, the junction of the second and third portion of the duodenum inferiorly (B), and the junction of the neck and body of the pancreas medially (C). 10% pancreas Duodenal gastrinomas tend to be quite small and are often multiple. They have less malignant potential than the solitary, sporadic pancreatic gastrinomas. Gastrin Gastrin has trophic action on parietal cells and histamine-secreting enterochromaffin-like (ECL) cells. Gastrin stimulates parietal cells largely via the release of histamine. 75% 14 % 11 % 90 % Z-E develop peptic ulcers-solitary ulcers <1 cm in diameter. Mets to liver and bone in 1/3rd at presentation. Clinical Presentation:The ulcers recur much more often than in patients with sporadic ulcer disease.Diarrhoea is caused by the high volume of gastric acid that isnt reabsorbed.Diarrhoea is also caused by excess acid which neutralizes pancreatic enzymes and damages small bowel.-Gastrin inhibits absorption of intestinal sodium and water by the small intestine, thereby exacerbating the diarrhoea.
