Does fluoroscopy prevent inadvertent parathyroidectomy in thyroid surgery?

Area of Science:

• Surgical Innovation
• Medical Imaging
• Endocrinology

Background:

• Inadvertent parathyroidectomy during thyroidectomy leads to hypoparathyroidism.
• Near-infrared (NIR) imaging offers potential for intraoperative parathyroid gland identification via autofluorescence.
• The clinical utility of NIR imaging in thyroid surgery remains unestablished.

Purpose of the Study:

• To evaluate if near-infrared imaging reduces inadvertent parathyroidectomy during thyroidectomy.
• To assess if NIR imaging prevents early hypocalcemia as a surrogate for permanent hypoparathyroidism.

Main Methods:

• Prospective cohort study comparing NIR imaging with a historical control group.
• NIR imaging used to identify parathyroid glands on specimens and in the thyroid bed.
• Autotransplantation of identified parathyroid tissue; incidence of inadvertent parathyroidectomy recorded.
• Serum calcium and parathyroid hormone levels monitored postoperatively.

Main Results:

• 106 patients in the NIR imaging group and 163 in the control group.
• No statistically significant difference in inadvertent parathyroidectomy rates between groups (12.3% vs 10.4%).
• No significant difference in serum calcium or parathyroid hormone levels observed between groups at any time point.

Conclusions:

• Near-infrared imaging can detect inadvertent parathyroidectomy and facilitate autotransplantation.
• NIR imaging did not decrease the incidence of missed inadvertent parathyroidectomy.
• Current NIR imaging technology does not demonstrate sufficient clinical benefit for routine use in thyroidectomy.
