Localization of parathyroid lesions: blind study for surgeons

ABSTRACT

Success in the treatment of primary hyperparathyroidism rest in the accurate localization and removal of the diseased gland or glands. Computerized tomography and nuclear imaging scans are being used to localize abnormal parathyroid tissue. In the present study, fifteen consecutive patients undergoing surgery for primary hyperparathyroidism were all subjected to these ancillary studies. Results were not revealed to the operating team. In all instances an adenoma was localized during neck exploration. CT Scan failed to localize 73% of the affected glands. Nuclear scans missed almost fifty percent of the parathyroid adenomas. The low yield of these ancillary localizing tests makes them unnecessary in the routine evaluation of patients undergoing surgery for primary hyperparathyroidism
