Purpose:
(99m)Tc-Methoxyisobutylisonitrile ((99m)Tc-MIBI)-guided surgery for the detection of abnormal parathyroid glands in primary hyperparathyroidism (1-HPT) has gained popularity as an effective technique. However, in secondary hyperparathyroidism (2-HPT), the efficacy of this method remains controversial, especially for the recurrence sites of 2-HPT.
Methods:
(99m)Tc-MIBI-guided surgery was performed for 28 recurrent sites of transplanted parathyroid tissue in 4 patients, and the detection rates of this method were compared with the results of preoperative ultrasound (US) examination and computed tomography (CT) scanning.
Results:
The results of (99m)Tc-MIBI-guided surgery for regions of recurrence were a sensitivity of 100% (28/28) and an accuracy of 100% (29/29), compared with preoperative US and CT which had a sensitivity of 92.9% (26/28) and 0% (0/28), and an accuracy of 89.7% (26/29) and 0% (0/28), respectively.
Conclusions:
Intraoperative (99m)Tc-MIBI-guided surgery can identify recurrent parathyroid tissues of 2-HPT more precisely than preoperative US examination or CT scanning, and makes the surgery easier to perform.
