Initial clinical experiences using the intraoperative probe-based parathyroid autofluorescence identification...

Area of Science:

• Medical Devices
• Surgical Technology
• Biophotonics

Background:

• The FDA has cleared the PTeye™ system, a probe-based near-infrared autofluorescence (NIRAF) detection system.
• PTeye™ is intended as an adjunct tool for label-free intraoperative parathyroid gland (PG) identification.
• Previous investigations of PTeye™ were conducted in a blinded manner.

Purpose of the Study:

• To evaluate the preliminary impressions of PTeye™ when used by surgeons without blinding to the device output.
• To assess the utility of PTeye™ as an adjunct tool for intraoperative PG identification.

Main Methods:

• Prospective recruitment of patients undergoing thyroid and parathyroid procedures.
• Intraoperative assessment of target tissues using the PTeye™ system.
• Recording surgeon confidence in PG identification alongside real-time NIRAF parameters from PTeye™.

Main Results:

• Retrospective review of data from 83 patients (46 parathyroid, 37 thyroid procedures).
• PTeye™ interrogated 336 target tissues, achieving 94.3% overall accuracy, 93.0% positive predictive value, and 100% negative predictive value.
• All participating surgeons reported increased confidence in intraoperative PG identification with PTeye™.

Conclusions:

• Probe-based NIRAF detection with PTeye™ is a valuable adjunct device for intraoperative PG identification.
• The system assists surgeons across varied training and experience levels.
• PTeye™ enhances surgeon confidence in identifying parathyroid glands during surgery.
