Preoperative Tc-99m MIBI scintigraphy and intraoperative gamma probe (IGP) effectively locate parathyroid adenomas in primary hyperparathyroidism (PHPT) patients, reducing surgery time and complications.

Area of Science:

  • Endocrinology
  • Nuclear Medicine
  • Surgical Oncology

Background:

  • Primary hyperparathyroidism (PHPT) often requires surgical neck exploration.
  • Accurate localization of parathyroid adenomas or hyperplasia is crucial to minimize operative time and extent.
  • Preoperative imaging and intraoperative tools can aid surgical precision.

Purpose of the Study:

  • To evaluate the efficacy of preoperative Technetium-99m Methoxyisobutyl Isonitrile (Tc-99m MIBI) scintigraphy and intraoperative gamma probe (IGP) in PHPT.
  • To assess the impact of these localization techniques on surgical outcomes.

Main Methods:

  • Six patients with PHPT underwent preoperative Tc-99m MIBI scintigraphy.
  • Intraoperative gamma probe (IGP) was utilized during surgical neck exploration.

Main Results:

  • Tc-99m MIBI scintigraphy identified parathyroid adenomas in 2 out of 6 patients.
  • The IGP accurately detected these adenomas during surgery, facilitating quick removal (35 min) with small incisions.
  • In 4 patients without abnormal MIBI uptake, subtotal parathyroidectomy was performed.
  • Pathologic examination confirmed parathyroid adenoma in the identified cases.

Conclusions:

  • Preoperative Tc-99m MIBI scintigraphy combined with IGP can significantly limit surgical neck exploration.
  • These methods have the potential to reduce operative time and decrease surgical complications in PHPT management.
