Does parathyroid autofluorescence reduces unintentional parathyroidectomy during total thyroidectomy with central...

Area of Science:

• Endocrinology
• Surgical Oncology
• Medical Imaging

Background:

• Postoperative hypoparathyroidism is a common complication following thyroid surgery.
• Parathyroid autofluorescence is a promising tool for intraoperative parathyroid gland localization.

Purpose of the Study:

• To assess the effectiveness of intraoperative autofluorescence imaging in reducing parathyroid gland excision during total thyroidectomy with central lymph node dissection.
• To evaluate the impact of autofluorescence on postoperative parathyroid hormone levels and serum calcium.

Main Methods:

• A prospective randomized study involving 180 patients undergoing total thyroidectomy with central lymph node dissection.
• Patients were divided into two groups: without (A) and with (B) FLUOBEAM® LX autofluorescence imaging.
• Intraoperative identification of parathyroid glands and postoperative biochemical assessments were recorded.

Main Results:

• Autofluorescence imaging identified a significantly higher number of parathyroid glands compared to visual inspection (p=0.03).
• Fewer parathyroid glands were found in surgical specimens from the autofluorescence group (p=0.06).
• The autofluorescence group showed a trend towards lower incidence of transient postoperative hypoparathyroidism (p=0.058).

Conclusions:

• Parathyroid autofluorescence is a safe and effective tool for experienced surgeons during central compartment dissection.
• This imaging technique can improve the rates of postoperative hypoparathyroidism and enhance the quality of lymph node dissection.
• Autofluorescence imaging aids in distinguishing parathyroid glands from lymph nodes, optimizing surgical outcomes.
