What this trial studies

This study evaluates the effectiveness of near infrared autofluorescence (NIRAF) detection using the FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands during parathyroidectomy procedures. It aims to determine if the use of NIRAF improves outcomes compared to traditional surgeon detection methods. The study will compare the risk-benefit profiles and surgical outcomes in patients undergoing parathyroid surgery with and without the use of NIRAF detection.

Who should consider this trial

Good fit: Ideal candidates include individuals with primary hyperparathyroidism or those undergoing repeat surgery for persistent primary hyperparathyroidism.

Not a fit: Patients with concurrent thyroid disease requiring total thyroidectomy or those with secondary or tertiary hyperparathyroidism may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved identification of parathyroid glands, reducing complications and improving surgical outcomes for patients with hyperparathyroidism.

How similar studies have performed: Other studies have shown promising results with similar intraoperative identification techniques, suggesting potential for success in this approach.

Inclusion Criteria:

* Primary hyperparathyroidism who will be undergoing parathyroid surgery
* Persistent primary hyperparathyroidism after having undergone a failed prior parathyroid surgery who will be undergoing repeat parathyroid surgery

Exclusion Criteria:
