    Abstract:
    BACKGROUND: Minimal invasive surgery for parathyroidectomy has been introduced in the treatment of hyperparathyroidism. OBJECTIVE: To evaluate the contribution of the sestamibi-SPECT (MIBI) localization, cervical ultrasonography, and intraoperative rapid turbo intact parathormone assay in minimal invasive parathyroidectomy. METHODS: Between August 1999 and March 2004, 146 consecutive hyperthyroid patients were treated using the MIBI and ultrasound for preoperative localization and iPTH measurements for intraoperative assessment. RESULTS: Parathyroid adenoma was detected in 106 patients, primary hyperplasia in 16, secondary hyperplasia in 16, tertiary hyperplasia in 5, and parathyroid carcinoma in 1 patient. Minimal invasive exploration of the neck was performed in 84 of the 106 patients (79.2%) with an adenoma, and in 17 of them this procedure was performed under local cervical block anesthesia in awake patients. Adenoma was correctly diagnosed by MIBI scan in 74% of the patients, and by ultrasound in 61%. The addition of ultrasonography to MIBI increased the accuracy of adenoma detection to 83%. In 2 of the 146 patients (1.4%) iPTH could not be significantly reduced during the initial surgical procedure. Minimal invasive surgery with minimal morbidity, and avoiding bilateral neck exploration, was achieved in 79.2% of patients with a primary solitary adenoma. CONCLUSIONS: Preoperative localizationof the parathyroid gland by MIBI and ultrasound together with intraoperative iPTH measurements resulted in an overall cure rate of 98.6% for the entire series, The addition of ultrasound to the MIBI scan increased the accuracy of adenoma detection.
