Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will see if the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands (PGs) during parathyroidectomy (PTx) procedures is better than a surgeon's detection alone. It compares risk-benefits and outcomes in PTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.

Parathyroidectomy - look at application of the technology to see if it assists during a parathyroidectomy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Prior to data collection, it was determined some additional outcome measures collected by the primary site would not be relevant to the trial for participating sites such as this site. Those outcomes were removed from this record.

Blinding Strategy

SINGLE

Participants
Only participants will be masked to the intervention

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

PTeye

The surgeon will use the PTeye as an intraoperative tool to identify if a suspect tissue is a parathyroid or not, during the parathyroid surgery.

Group Type EXPERIMENTAL

PTeye

Intervention Type DEVICE

The surgeon will first take 5 baseline NIRAF measurements on the thyroid gland (or neck muscle, if thyroid is absent) using the disposable sterile fiber probe that is connected to the PTeye console (see Figure 1), as per device functionality requirements.

Standard of Care

The surgeon will rely solely on her/his surgical experience in identifying the parathyroid glands during the operations.

Group Type OTHER

Standard of Care

Intervention Type OTHER

The surgeon will rely solely on her/his surgical experience in identifying the parathyroid glands during the operations.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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

* Pregnant women (Those patients who could potentially will receive preoperative pregnancy testing, as is standard before general anesthesia. Any patients with positive pregnancy test results will not be included in the study.)
* Patients with concurrent parathyroid and thyroid disease that require total thyroidectomy
* Patients with secondary or tertiary hyperparathyroidism
