Pre-operative localization of abnormal parathyroid tissue helps in deciding whether surgery begins with a neck or mediastinal exploration. In this study we aimed to evaluate the usefulness of parathyroid scintigraphy in pre-operative localization of parathyroid adenomas and treatment. From February 2006 to October 2008, patients with signs and symptoms of hyperparathyroidism were recruited to join the study. The study group consisted of 3 males and 8 females. All subjects had a pre-operative parathyroid scintigraphy with Tc99m Sestamibi followed by parathyroidectomy. Ten patients had a positive scintigraphic finding which correlated to the actual location of the adenoma determined during the operation. Almost all patients (10 out of 11) underwent minimally invasive parathyroidectomy (MIP) while only one patient underwent bilateral neck dissection. The average incision length was 3.73 + 0.65 cm. Only one patient had an adverse event (transient hypocalcemia and bleeding necessitating a drain) which resolved later. The average hospital stay was 2.5 + 0.7 days. Parathyroid Tc99m-sestamibi scan is a reliable, non-invasive, and cost effective imaging modality in pre-operative localization of parathyroid adenomas for first time parathyroidectomy. This can help and guide surgeons to perform focused parathyroid surgery with minimal incision, successful localization, less complications, and shorter hospital stays.
