Nuclear mapping in parathyroidectomy: the impact on operative time

Area of Science:

• Endocrinology
• Surgical Oncology
• Nuclear Medicine

Background:

• Parathyroidectomy requires precise localization of hyperactive parathyroid tissue, a persistent surgical challenge.
• Nuclear mapping, utilizing 99mTc Sestamibi accumulation in abnormal tissue, offers a novel intraoperative solution.
• This technique involves detecting radioactivity to identify hyperactive glands.

Purpose of the Study:

• To evaluate the impact of nuclear mapping on operative time during parathyroidectomy.
• To assess the efficiency of nuclear mapping as an adjuvant surgical technique.

Main Methods:

• Retrospective analysis of clinical data from 27 patients undergoing parathyroidectomy.
• Univariable and multivariable analyses were performed to identify factors influencing operative time.
• Statistical methods included regression modeling to determine independent predictors of duration.

Main Results:

• Nuclear mapping was associated with a significant reduction in operative time (79.4 min vs. 135.8 min, p=0.0186).
• Bilateral neck exploration, partial sternotomy, and reoperative neck procedures prolonged operative time.
• Multivariable analysis confirmed nuclear mapping, sternotomy, and reoperation as independent factors affecting parathyroidectomy duration.

Conclusions:

• Nuclear mapping is an effective intraoperative tool for localizing and identifying hyperactive parathyroid tissue.
• The technique guides surgeons, leading to a significant decrease in operative time for parathyroidectomy.
• Nuclear mapping enhances surgical precision and efficiency in parathyroid gland surgery.
