Evaluating Impact of Near Infrared Autofluorescence (NIRAF) Detection for Identifying Parathyroid Glands During Parathyroidectomy

- Registration Number
- NCT05022641
- Lead Sponsor
- University of Michigan
- Brief Summary
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
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.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 160
- 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
- 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

- Primary Outcome Measures
Name Time Method Average Number of Parathyroid Glands Identified Measured within the procedure, generally not more than 2 hours Average number of parathyroid glands identified between the Experimental Group: Glands identified with naked eye + NIRAF vs. the Control Group: Glands identified with naked eye.
- Secondary Outcome Measures
Name Time Method Parathyroid Hormone (PTH) Levels 5-14 Days After Surgery 5-14 days after surgery Parathyroid hormone (PTH) levels 5-14 days after surgery. Higher levels could indicate failure of operation. Low levels could indicate temporary or permanent parathyroid damage.
Appropriate Intraoperative Parathyroid Hormone Drop baseline to 10 minutes \>50% drop from baseline at 10 minutes post-resection
Duration of Surgery in Minutes Measured within the procedure, generally not more than 2 hours Surgery duration in minutes
Number of Nights Spent in the Hospital After Parathyroidectomy 0-72 hours after PTx procedure Number of nights spent for postoperative recovery in the hospital after the surgical procedure.
Number of Frozen Sections total number of frozen sections sent to confirm parathyroid gland identity, immediate. Total number of frozen sections conducted for patients undergoing repeat surgery or bilateral neck explorations. Frozen sections were conducted to confirm that the parathyroid tissue for the targeted over-acting parathyroid was removed. Results reflect whether participants had a frozen section conducted.
