Real-time detection of parathyroid glands during surgery using a highly sensitive autofluorescence-based system

Area of Science:

• Surgical Technology
• Biomedical Engineering
• Medical Diagnostics

Background:

• Accurate identification and localization of parathyroid tissue during surgery is a significant clinical challenge.
• Protecting functional parathyroid integrity and preventing intraoperative damage are critical for patient outcomes.

Purpose of the Study:

• To develop and validate a laser-induced fluorescence detection system for real-time parathyroid gland localization.
• To assess the system's accuracy and reliability in a clinical surgical setting.

Main Methods:

• A prospective study involving 106 patients undergoing surgery.
• Development of a laser-induced fluorescence detection system utilizing intrinsic tissue fluorescence.
• Measurement of fluorescence intensity values to differentiate parathyroid tissue during surgery.

Main Results:

• The system achieved a 98.3% detection accuracy rate in over 100 clinical cases.
• Demonstrated superior performance compared to existing systems and naked-eye recognition.
• The system effectively overcomes environmental light interference for improved imaging.

Conclusions:

• The developed parathyroid gland detection system accurately identifies parathyroid glands in real-time.
• Provides an effective solution for intraoperative localization, potentially improving surgical decision-making.
• May lead to enhanced patient prognosis by reducing parathyroid-related complications.
