Summary
Minimally invasive parathyroidectomy (MIP) using intraoperative rapid parathyroid hormone (iPTH) assay is a safe and effective treatment for hyperparathyroidism. This technique enables limited dissection and early discharge for most patients.
Area of Science:
- Endocrinology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Intraoperative rapid parathyroid hormone (iPTH) assay is transforming parathyroid surgery.
- This study examines a single surgeon's experience adopting minimally invasive parathyroidectomy (MIP) at a tertiary care hospital.
Purpose of the Study:
- To evaluate the safety and efficacy of MIP guided by iPTH monitoring.
- To assess the feasibility of same-day discharge for patients undergoing MIP.
Main Methods:
- A prospective case study involving 101 patients undergoing MIP with technetium 99m sestamibi scanning and iPTH monitoring.
- iPTH levels were measured at multiple intraoperative intervals to confirm successful parathyroid gland excision.
- MIP was considered complete when iPTH levels decreased by more than 50% from preoperative levels.
Main Results:
- 83% of patients with single adenomas were discharged on the day of surgery.
- Postoperative serum calcium and parathyroid hormone levels showed significant improvement (p < 0.001).
- One patient experienced persistent hyperparathyroidism; 16% had elevated PTH without hypercalcemia post-operation.
Conclusions:
- MIP combined with iPTH monitoring is a safe and effective approach for hyperparathyroidism treatment.
- This surgical strategy facilitates limited dissection and allows for early patient discharge.
