Computer Vision-Based Recognition of Parathyroid Glands and Recurrent Laryngeal Nerves in Endoscopic Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

PTAIR Computer Vision Model Assessment: PTAIR is a computer vision model used to recognize parathyroid glands and recurrent laryngeal nerves in endoscopic thyroid surgery videos. In this observational study, PTAIR will be used to analyze recorder-based intraoperative videos and evaluate first recognition time, continuous recognition time, and recognition performance. PTAIR results will be compared with recognition by junior and senior physicians based on the same intraoperative endoscopic visual field and the same video recording timeline. At this stage, PTAIR will not be used to guide intraoperative surgical decision-making.

Study summary

This study aims to evaluate the performance of the PTAIR computer vision model for recognizing parathyroid glands and recurrent laryngeal nerves during endoscopic thyroid surgery. Multicenter intraoperative endoscopic surgery videos will be prospectively collected. Using the video recorder timeline as the unified time reference, the first recognition time of parathyroid glands and recurrent laryngeal nerves by PTAIR, junior physicians, and senior physicians will be recorded during surgery. The continuous recognition time of parathyroid glands and recurrent laryngeal nerves by PTAIR will also be recorded.

This study focuses on the recognition performance of PTAIR in real-world multicenter endoscopic thyroid surgery settings. At this stage, PTAIR will not be used to guide intraoperative surgical decision-making, and the study will not evaluate the effect of PTAIR on clinical outcomes. The collected video data will be used to assess the performance of PTAIR under different centers, surgeons, equipment conditions, and surgical field conditions, and may provide data support for future model optimization.

Eligibility

Primary outcome measure(s)

• First Recognition Time of the Recurrent Laryngeal Nerve — Intraoperative period
  Using the video recorder timeline as the unified time reference, the first recognition time of the recurrent laryngeal nerve by PTAIR, junior physicians, and senior physicians will be recorded during surgery. All recognitions will be based on the same intraoperative endoscopic visual field.
• First Recognition Time of the Parathyroid Gland — Intraoperative period
  Using the video recorder timeline as the unified time reference, the first recognition time of the parathyroid gland by PTAIR, junior physicians, and senior physicians will be recorded during surgery. All recognitions will be based on the same intraoperative endoscopic visual field.
• Continuous Recognition Time of the Recurrent Laryngeal Nerve — Intraoperative period
  Using the video recorder timeline as the unified time reference, the continuous recognition time of the recurrent laryngeal nerve by PTAIR will be recorded during surgery.
• Continuous Recognition Time of the Parathyroid Gland — Intraoperative period
  Using the video recorder timeline as the unified time reference, the continuous recognition time of the parathyroid gland by PTAIR will be recorded during surgery.
