  • Title: Pseudo-Zollinger-Ellison syndrome: hypergastrinemia, hyperchlorhydria without tumor.
    Author: Friesen SR, Tomita T.
    Journal: Ann Surg; 1981 Oct; 194(4):481-93. PubMed ID: 7283508.
    Abstract:
    The purpose of the investigation was to detect ulcer patients having nontumorous hypergastrinemic hyperchlorhydria and to diagnostically differentiate this pseudo-Zollinger-Ellison syndrome from neurogenic duodenal ulcer disease and pancreatic gastrinomas. Nine patients having clinical, radiologic and humoral findings simulating the Zollinger-Ellison syndrome or severe duodenal ulcer disease were studied by physiologic provocative testing. The patients, not having pancreaticoduodenal gastrinomas, had an antral mucosal source of their moderate hypergastrinemia even after vagotomy with drainage, which was eliminated in eight patients treated by surgical antrectomy, resulting in normal serum gastrin concentrations. The pseudo-Zollinger-Ellison syndrome is, thus, characterized physiologically by an exaggerated gastrin response to meals, no response to secretin stimulation and pathologically by hyperfunctioning hyperplastic G cells of the antrum. The clinical, physiologic, pathologic and surgical features were integrated for accurate diagnosis and treatment.
