Differentiating Zollinger-Ellison syndrome from other Diseases

Zollinger-Ellison syndrome must be differentiated from:

• Gastric antrum syndrome
• Antral G-cell hyperplasia
• Peptic ulcer
• Gastroesophageal reflux disease (GERD)
• Hypergastrinemia

Differential diagnosis of hypergastrinemia

Differential diagnosis of Hypergastrinemia

Gastrinoma Gastric outlet obstruction Retained antrum syndrome Previous vagotomy Antral G cell hyperplasia/hyperfunction Pernicious anemia Atrophic gastritis Short gut syndrome Renal Failure
