Localization of Parathyroid Adenoma and Minimally Invasive Parathyroidectomy: A Review / 대한내분비외과학회지

ABSTRACT

More than 80% of cases of patients with sporadic primary hyperparathyroidism are caused by a single parathyroid adenoma. Therefore, traditional bilateral neck exploration has been replaced by minimally invasive parathyroidectomy (MIP) in recent years. Benefits, of MIP include decreased pain and complications, a shorter length of hospital stay, and improved cosmesis. Preoperative imaging studies for localization and intraoperative PTH assay (IoPTH) play an essential role for in MIP. The standard imaging studies are cervical ultrasound and 99mTc sestamibi scanning (with SPECT/CT), while 4D CT is attracting significant interest. The half-life of PTH is less than 5 minutes and PTH rapidly drops after the resection of target lesions. These characteristics of PTH enable IoPTH. If target lesions are localized by recent imaging studies and IoPTH is adopted, MIP can be performed successfully in patients with primary hyperparathyroidism.
