Autofluorescence-Guided Total Thyroidectomy in Low-Volume, Nonparathyroid Institutions

Area of Science:

• Endocrinology
• Surgical Oncology
• Medical Technology

Background:

• Hypoparathyroidism is a frequent complication of thyroid surgery, particularly when performed by less experienced surgeons.
• Low-volume, nonparathyroid institutions face challenges in managing this complication.

Purpose of the Study:

• To assess the impact of autofluorescence on hypoparathyroidism rates following total thyroidectomy.
• To compare outcomes in low-volume centers before and after the introduction of autofluorescence.

Main Methods:

• A prospective, multicenter cohort study in Denmark compared patients undergoing autofluorescence-guided total thyroidectomy with a historical cohort.
• The study included 78 patients with autofluorescence and 89 in the historical group, with a 1-year follow-up.
• Hypoparathyroidism was defined by the need for active vitamin D postoperatively and at 1 year.

Main Results:

• Immediate hypoparathyroidism decreased from 37% to 19% (P=.02) with autofluorescence.
• Permanent hypoparathyroidism rates dropped from 32% to 6% (P<.001), reaching 0% by study end.
• Autofluorescence improved parathyroid gland identification (75% vs 61%) and reduced inadvertent excision (4% vs 21%).

Conclusions:

• Autofluorescence-guided total thyroidectomy significantly reduces immediate and permanent hypoparathyroidism in low-volume institutions.
• The technique yields outcomes comparable to high-volume parathyroid surgeons.
• Autofluorescence is a valuable tool for improving surgical safety and patient outcomes in thyroidectomies.
