Endoscopic parathyroidectomy shows promise for hyperparathyroidism treatment, offering good visualization and acceptable cosmesis. However, technical challenges in accessing certain neck structures remain.

Area of Science:

  • Endocrinology
  • Minimally Invasive Surgery
  • Surgical Oncology

Background:

  • Minimally invasive surgery (MIS) techniques are increasingly explored for neck procedures.
  • Previous MIS attempts in the neck provide a foundation for endoscopic approaches.

Purpose of the Study:

  • To evaluate the feasibility and outcomes of endoscopic parathyroidectomy in patients with hyperparathyroidism.
  • To assess the technical challenges and benefits of using endoscopic techniques for parathyroid gland surgery.

Main Methods:

  • Endoscopic parathyroidectomy was attempted in three patients with hyperparathyroidism (two with hyperfunctioning adenoma, one with hyperplasia).
  • Preoperative localization of hyperfunctioning tissue was performed using a 99Tc-thallium subtraction scan.
  • Surgical technique involved maintaining a working space with good hemostasis and utilizing magnification for structure identification.

Main Results:

  • Successful localization and dissection of parathyroid tissue were achieved in two out of three patients.
  • One patient required conversion to open hemithyroidectomy for adenoma excision.
  • Average operative time was 113 minutes; excellent magnification aided in identifying neck structures.
  • Mobilization of the lateral thyroid lobe for tracheoesophageal groove access proved technically difficult.
  • No significant or prolonged subcutaneous emphysema was observed; cosmesis was acceptable.

Conclusions:

  • Endoscopic parathyroidectomy is a viable option for select hyperparathyroidism cases, offering good visualization and cosmetic results.
  • Technical difficulties, particularly in mobilizing thyroid lobes, need to be addressed for wider application.
  • Further refinement of endoscopic techniques is warranted to overcome anatomical challenges in neck surgery.
