Summary
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.
