  • Title: [Minimally invasive parathyroidectomy for treatment of primary hyperparathyroidism caused by parathyroid adenoma].
    Author: Krausz MM, Ish-Shalom S, Ofer A.
    Journal: Harefuah; 2010 Jun; 149(6):353-6, 404. PubMed ID: 20941923.
    Abstract:
    BACKGROUND: Minimally invasive parathyroidectomy (MIP) is frequently used for the treatment of primary hyperparathyroidism (PHPT) caused by a single adenoma. This method depends on preoperative localization of the tumor by a sestamibi scan, cervical ultrasound, and intraoperative parathyroid hormone (PTH) measurements. When the sestamibi scan is negative, the classical 4-gland exploration is used instead of MIP. AIMS: a. To evaluate the effectiveness of MIP for treatment of PHPT caused by adenoma. b. To evaluate the use of PTH selective venous sampling (PTH-SVS) in patients with negative sestamibi scintigraphy. METHODS: MIP was performed in all patients in whom an adenoma was diagnosed by sestamibi scan and US. When the sestamibi scan was negative, PTH-SVS was performed preoperatively for localization of the adenoma. RESULTS: Parathyroidectomy was performed in 541 patients, 458 with PHPT and 83 with secondary hyperparathyroidism. In 345 of 380 patients (90.8%) with an adenoma, MIP was performed, and in 92 of these patients the operation was performed under local anesthesia. A total of 444 (97.0%) of the patients with PHPT were cured by the surgery. In 56 patients with a negative sestamibi scan, PTH-SVS was used preoperatively for localization of an adenoma. In 30 of these cases (53%) MIP was successfully performed in spite of a negative sestamibi scan. CONCLUSIONS: MIP is the treatment of choice for PHPT caused by a single adenoma. When the preoperative sestamibi scan is negative, the authors recommend the use of PTH-SVS for preoperative localization. This resulted in 53% successful MIP in patients with a negative sestamibi scan.
