Zollinger-Ellison syndrome

Zollinger-Ellison syndrome (ZES) is a condition caused by gastrin-producing neuroendocrine tumor that causes gastric acid hypersecretion and peptic ulcer disease.

Can be sporadic or associated with multiple endocrine neoplasia syndrome type 1.

Common presentation includes refractory peptic ulcer disease, abdominal pain, diarrhea, and gastroesophageal disease.

The main goal of treatment is control of gastric hypersecretion with proton-pump inhibitors.

The most common cause of morbidity and mortality is metastatic gastrinoma.

Zollinger-Ellison syndrome is a condition caused by a gastrin-secreting tumor that causes hypersecretion of gastric acid leading to ulcer disease. It most commonly presents with abdominal pain (70% to 100% of patients), diarrhea (37% to 73% of patients), and gastroesophageal reflux disease (44% of patients). Less common presentations include weight loss, gastrointestinal bleeding, nausea, and vomiting.[1]Nieto JM, Pisegna JR.
