Zollinger-Ellison syndrome: a personal perspective

Area of Science:

• Gastrointestinal endocrinology
• Surgical management of neuroendocrine tumors

Background:

• Zollinger-Ellison Syndrome (ZES) involves severe peptic ulcer disease caused by gastrin-secreting tumors.
• Initial surgical approaches focused on managing severe ulcer complications.

Purpose of the Study:

• To review the historical evolution of Zollinger-Ellison Syndrome management.
• To highlight the shift in surgical strategy with advancements in medical and diagnostic technologies.
• To emphasize the importance of early surgical intervention for malignant potential.

Main Methods:

• Historical review of Zollinger-Ellison Syndrome progression.
• Analysis of treatment paradigm shifts from total gastrectomy to tumor-focused surgery.
• Integration of diagnostic advancements like radioimmunoassay and imaging.

Main Results:

• Discovery of gastrin as the causative hormone led to the field of gastrointestinal endocrinology.
• Proton pump inhibitors reduced the need for total gastrectomy.
• Current understanding acknowledges the malignant potential of all gastrinomas.

Conclusions:

• Early surgical removal of gastrinomas is crucial for improving survival and reducing metastases.
• Surgical intervention benefits both sporadic and familial forms of ZES.
• Management has transitioned to a focus on tumor resection and metastatic prevention.
