Summary
Minimally invasive endoscopic surgery for primary hyperparathyroidism (pHPT) is effective when guided by accurate imaging and intraoperative parathyroid hormone (PTH) monitoring. This approach ensures surgical success in select patients with pHPT.
Area of Science:
- Endocrinology
- Surgical Oncology
- Minimally Invasive Surgery
Background:
- Primary hyperparathyroidism (pHPT) management relies on precise preoperative localization and intraoperative parathyroid hormone (PTH) monitoring.
- Endoscopic-assisted parathyroidectomy offers a minimally invasive option for pHPT.
Purpose of the Study:
- To evaluate the efficacy and outcomes of minimally invasive endoscopic-assisted parathyroidectomy for sporadic pHPT.
- To assess the role of preoperative imaging and intraoperative quick PTH monitoring in surgical success.
Main Methods:
- Patients with sporadic pHPT and a single enlarged gland on imaging underwent endoscopic-assisted parathyroidectomy.
- Intraoperative quick PTH monitoring was used to confirm surgical success, defined as a >50% PTH level decrease postexcision.
- Surgical outcomes, localization accuracy, and the impact of quick PTH assay were analyzed.
Main Results:
- 66 out of 107 patients (62%) were selected for endoscopic surgery.
- 99mTc-Sestamibi scintigraphy showed 97% accuracy in localization.
- Surgical success was achieved in most patients, with a median follow-up of 9 months confirming cure of hypercalcemia.
Conclusions:
- Minimally invasive endoscopic-assisted parathyroidectomy is a viable and expeditious approach for select pHPT patients.
- Accurate preoperative localization (99mTc-Sestamibi) and intraoperative quick PTH monitoring are crucial for ensuring surgical success.
- Careful interpretation of quick PTH assay results is essential for optimal outcomes.
