Zollinger-Ellison syndrome (ZE) involves tumors causing excess stomach acid, leading to severe ulcers. Early diagnosis and aggressive surgical resection of gastrinomas, especially duodenal ones, improve long-term survival for patients with this rare condition.

Area of Science:

  • Gastroenterology
  • Endocrinology
  • Surgical Oncology

Background:

  • Zollinger-Ellison syndrome (ZE) is characterized by gastrin-producing tumors (gastrinomas) leading to severe peptic ulcer disease.
  • Historically, diagnosis and management have evolved, with significant improvements in outcomes.
  • This study reviews a long-term institutional experience with ZE syndrome patients.

Purpose of the Study:

  • To analyze the clinical characteristics, diagnostic challenges, and treatment outcomes of Zollinger-Ellison syndrome.
  • To evaluate the efficacy of surgical resection and total gastrectomy in managing ZE syndrome.
  • To emphasize the importance of aggressive localization and resection of gastrinomas.

Main Methods:

  • Retrospective review of 30 patients with Zollinger-Ellison syndrome treated from 1947 to the present.

  • Analysis of patient demographics, clinical symptoms, ulcer types, gastrinoma location, and treatment modalities.
  • Evaluation of operative mortality and long-term survival rates.

    • Main Results:

    • Most patients (70%) were male, with a mean symptom duration of 5.8 years before diagnosis.
    • Duodenal ulcers occurred in 96% of patients; gastrinomas were most commonly duodenal (38%) or pancreatic (34%).
    • Aggressive resection was favored when distant metastases were absent, with duodenal gastrinomas showing favorable outcomes.

    Conclusions:

    • Early and aggressive surgical management, including tumor resection, is crucial for improving survival in Zollinger-Ellison syndrome.
    • Localization and resection of gastrinomas, particularly duodenal tumors, offer the best chance for cure.
    • Despite challenges with occult tumors, an aggressive approach to localization and resection improves outcomes.
