Zollinger-Ellison syndrome is a rare disorder that occurs when one or more tumors form in the pancreas and duodenum. The tumors, called gastrinomas, release large amounts of gastrin that cause the stomach to produce large amounts of acid..
do not know the exact cause of Zollinger-Ellison syndrome. About 25 to 30 percent of gastrinomas are caused by an inherited genetic disorder called multiple endocrine neoplasia type 1 (MEN1).1 MEN1 causes hormone-releasing tumors in the endocrine glands and the duodenum.Zollinger-Ellison syndrome signs and symptoms are similar to those of peptic ulcers. A dull or burning pain felt anywhere between the navel and midchest is the most common symptom of a peptic ulcer. This discomfort usuallyOther symptoms include diarrhea bloating burping nausea vomiting weight loss poor appetite ...
Zollinger-Ellison syndrome (ZES) is caused by a non–beta islet cell, gastrin-secreting tumor of the pancreas that stimulates the acid-secreting cells of the stomach to maximal activity, with consequent gastrointestinal mucosal ulceration
The symptoms of Zollinger-Ellison syndrome (ZES) are secondary to hypergastrinemia, which causes hypertrophy of the gastric mucosa, leading to increased numbers of parietal cells and increased maximal acid output. Gastrin by itself also stimulates acid secretion, resulting in increased basal acid secretion. The large quantity of acid produced leads to gastrointestinal mucosal ulceration. It also leads to diarrhea and malabsorption.
The following complications may arise in patients with ZES: Abdominal perforation secondary to ulceration (The duodenum and jejunum are the most common sites.) Esophageal stricture, with reflux Bowel obstruction Gastrointestinal bleeding Gastric carcinoids (especially in patients with multiple endocrine neoplasia-type 1 [MEN 1])
symptoms include abdominal pain, heartburn, diarrhea, nausea, vomiting, gastrointestinal bleeding, and weight loss.
The goals of treatment in patients with Zollinger-Ellison syndrome (ZES) are medical control of gastric acid hypersecretion using proton- pump inhibitors and surgical resection of the tumor. Inpatient care is aimed at first controlling the gastric acid hypersecretion. Once gastric acid hypersecretion is controlled, imaging studies should be obtained to localize the tumor and determine tumor extent.
