Hypothesis Patients with primary hyperparathyroidism and negative preoperative localization imaging have a different outcome than patients with positive imaging.
Design Prospective single-surgeon case series.
Setting Referral center.
Patients Forty-two patients with primary hyperparathyroidism, indications for surgery, and both cervical ultrasonographic results and technetium Tc 99m sestamibi nuclear images that were nonlocalizing over a 5- year span.
Main Outcome Measures Extent of surgery required to produce cure; operative findings.
Results Of 430 patients undergoing surgery for primary hyperparathyroidism, 351 underwent both ultrasonographic and sestamibi imaging. Among 351 patients, the imaging results of 42 patients did not show an adenoma, and these patients underwent cervical exploratory surgery. Of 42 patients, 41 were cured at a mean follow-up of 90 days; 1 patient underwent surgical reexploration and was cured by removal of a mediastinal adenoma. To achieve initial cure, 12 of 42 patients (28.6%) required partial thyroidectomy, 9 (21.4%) required partial thymectomy, 17 (40.5%) required paratracheal dissection to access or devascularize an obscure adenoma. Pathologic examination disclosed single adenoma in 26 of 42 patients (61.9%), parathyroid hyperplasia in 14 (33.3%), and double adenoma in 2 (4.8%).
Conclusions Patients whose preoperative localization studies fail to localize solitary adenoma commonly require extensive surgery to cure hyperparathyroidism. Lack of localization may be a reasonable criterion on which to base referral of the patient to a high-volume medical center.
