Minimally invasive parathyroidectomy offers an 84% cure rate for primary hyperparathyroidism, with an overall 98% success rate when conversions to open surgery are included. While feasible, potential complications require careful consideration.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Primary hyperparathyroidism is a common endocrine disorder often requiring surgical intervention.
  • Parathyroidectomy is the definitive treatment, with evolving surgical techniques aiming for improved outcomes and reduced morbidity.

Purpose of the Study:

  • To evaluate the effectiveness and clinical outcomes of minimally invasive parathyroidectomy.
  • To compare the success rates and complication profiles of minimally invasive versus open parathyroidectomy.

Main Methods:

  • A prospective, non-randomised, non-blinded trial was conducted involving 50 patients undergoing minimally invasive parathyroidectomy and 150 patients undergoing open parathyroidectomy.
  • Data collected included cure rates (normocalcaemia), conversion rates, persistent disease, and complications such as recurrent laryngeal nerve palsy.

Main Results:

  • Minimally invasive parathyroidectomy achieved a cure rate of 84% (42/50 patients), with an overall success rate of 98% including conversions to open surgery.
  • Open parathyroidectomy demonstrated a 98% success rate (147/150 patients).
  • Temporary recurrent laryngeal nerve palsy occurred in three patients after minimally invasive procedures and one after open surgery. Intraoperative parathyroid hormone monitoring showed potential in identifying multiglandular disease.

Conclusions:

  • Minimally invasive parathyroidectomy is a viable surgical option for primary hyperparathyroidism.
  • While effective, the complication rate associated with minimally invasive parathyroidectomy warrants attention and further investigation.
