Summary

Persistent hyperparathyroidism was treated in two patients by re-exploring the neck and performing a closed mediastinal thymectomy. This approach successfully removed deep mediastinal parathyroid tumors embedded in the thymus gland, curing both patients.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Thoracic Surgery

Background:

  • Persistent hyperparathyroidism can result from missed or ectopic parathyroid adenomas.
  • Deep mediastinal parathyroid tumors, particularly those within the thymus, pose surgical challenges.
  • Previous surgical approaches for these tumors often involved median sternotomy.

Purpose of the Study:

  • To describe a minimally invasive surgical technique for treating persistent hyperparathyroidism caused by mediastinal parathyroid tumors.
  • To report the successful outcomes of treating deep mediastinal parathyroid tumors located within the thymus gland.

Main Methods:

  • Two patients with persistent hyperparathyroidism underwent re-exploration via a cervical incision.
  • A "closed mediastinal thymectomy" technique was employed to remove the entire thymus gland.

Related Experiment Videos

  • Histopathological examination confirmed enlarged parathyroid glands embedded within the resected thymus tissue.

    • Main Results:

    • Both patients were successfully treated and cured of persistent hyperparathyroidism.
    • The "closed mediastinal thymectomy" via cervical incision proved effective for removing mediastinal parathyroid tumors.
    • This approach avoided the need for a median sternotomy.

    Conclusions:

    • Cervical re-exploration combined with closed mediastinal thymectomy is a viable and effective treatment for deep mediastinal parathyroid tumors.
    • This technique offers a less invasive alternative to sternotomy for specific cases of persistent hyperparathyroidism.
    • Successful management of ectopic parathyroid tissue within the thymus gland can be achieved through this surgical approach.
