Neuroendocrine pancreatic tumors, like insulinomas, are rare neoplasms causing hypoglycemia. Surgical treatment is key, aided by advanced diagnostics for accurate tumor localization and successful enucleation.

Area of Science:

  • Endocrinology
  • Oncology
  • Gastroenterology

Background:

  • Neuroendocrine pancreatic tumors (NEPTs) are rare neoplasms from APUD cells, often hypersecreting peptides.
  • Insulinoma, the most common NEPT, arises from pancreatic beta cells and causes hypoglycemia due to excess insulin.
  • While typically benign (90%), insulinomas present with diverse symptoms like seizures, coma, and dizziness.

Observation:

  • Accurate tumor localization is crucial for effective surgical treatment of insulinomas.
  • Diagnostic tools include selective arteriography, intraoperative ultrasound, and pancreatic vein sampling with rapid insulin radioimmunoassay (Quick-RIA).

Findings:

  • This review details two cases of benign insulinomas in the pancreatic tail treated successfully via surgical enucleation.

  • The study highlights the importance of precise diagnostic methods for successful surgical outcomes.

    • Implications:

    • Early and accurate diagnosis of insulinomas improves surgical success rates and patient outcomes.
    • For unresectable cases, octreotide and chemotherapy can manage hormonal symptoms and disease progression.
