Abstract

Background: Successful preoperative localization plays an important role in patient selection for focused parathyroidectomy. Methods: The case records of 499 consecutive patients with presumed hyperparathyroidism who underwent neck exploration were reviewed. Positive imaging patients (n = 373) had a localizing study that clearly showed a single abnormal parathyroid gland whereas negative imaging patients (n = 44) failed to localize or had discordant imaging results. Results: Positive imaging patients were more likely to have a single adenoma (93.0% vs 72.1%; P < .001), and were less likely to require a bilateral exploration (8.1% vs 70.4%; P < .001). Negative imaging patients required more frozen sections (.9 ± 1.3 vs .2 ± .7; P < .001), and longer surgical time (77.3 ± 52.5 min vs 48.4 ± 34.6 min; P < .001). The cure rate was significantly higher in the positive imaging group (96.0% vs 87.1%; P < .03), with no difference in the incidence of complications (3.2% vs 2.3%; P value was not significant). Conclusions: Patients with unsuccessful or discordant preoperative localization have a higher incidence of multigland disease, lower cure rate, and consume more institutional resources than patients with successful preoperative localization.
