Summary

Surgical removal of pituitary microadenomas offers high remission rates for hormone hypersecretion while preserving normal pituitary function. Early diagnosis and treatment are crucial for successful outcomes in pituitary adenoma patients.

Area of Science:

  • Neurosurgery
  • Endocrinology
  • Oncology

Background:

  • Pituitary microadenomas are small tumors (<1 cm) requiring surgical intervention.
  • Treatment aims to resolve hormone hypersecretion and maintain normal pituitary function.

Purpose of the Study:

  • To evaluate the efficacy and safety of surgical removal for pituitary microadenomas.
  • To assess remission rates and complications in patients with various secreting adenomas.

Main Methods:

  • Retrospective analysis of 230 patients undergoing initial surgery for pituitary microadenomas.
  • Categorization of adenomas by hormone secretion: GH, PRL, ACTH, and TSH.

Main Results:

  • High remission rates achieved: 81% (GH), 77% (PRL), 91% (ACTH), 100% (TSH).

  • Low complication rate: no perioperative mortality, 5 major complications, 3.5% incidence of new-onset hypopituitarism.
  • 7 patients experienced temporary diabetes insipidus.

    • Conclusions:

    • Surgical removal of pituitary microadenomas is highly effective for disease remission.
    • Early diagnosis and treatment are essential to prevent tumor growth and ensure successful surgical outcomes.
