Twelve patients with Zollinger-Ellison syndrome and one patient with WDHA syndrome are reviewed. Three of the Z-E patients exhibited MEA, two having hyperinsulinism and one hyperparathyroidism. Ages ranged from nine to 71 years. Diagnosis of Z-E syndrome was established from history, gastric acid secretion, radiologic studies, serum gastrin measurements and from actual tissue biopsy in 10 of the 12 patients. Total gastrectomy was performed in 8 of the 12 Z-E patients, with abolition of the ulcer diathesis in all. However, in none of our patients was there objective evidence of subsequent tumor regression. Three patients remain alive. Four died of tumor, one from post-total gastrectomy complications, one from post-subtotal gastrectomy in another hospital, two from ulcer hemorrhage, and one from electrolyte imbalance with autopsy diagnosis of Z-E tumor. A patient is recorded in detail who exhibited both hyperinsulinemia and hypergastrinemia from a malignant islet cell tumor, had the tumor "debulked" four times over a 14 year period and whose hepatic metastases were temporarily abolished by streptozotocin infusion. The question is raised regarding relationships between chronic organic hyperinsulinism and subsequent hypergastrinemia.
