Bilateral neck exploration for primary hyperparathyroidism

Abstract

Controversy about the operative approach for primary hyperparathyroidism has prompted a review of our operative experience since 1980. We treated 73 patients with primary hyperparathyroidism during this 10-year period, all of whom underwent bilateral neck exploration in which the surgeons attempted to locate all parathyroid tissue. Thirty-eight patients (52%) were found to have a solitary adenoma, while 35 (48%) patients had multiple gland pathology. There were two cases of persistent hypercalcemia because of a synchronous parathyroid hormone-secreting malignancy in one patient and aberrant fifth gland adenoma in the other patient. Without bilateral neck exploration, about one-half of the patients in our series would not have been cured of primary hyperparathyroidism. Because of the high incidence of multiple parathyroid gland involvement, we conclude that thorough bilateral neck exploration must be considered the goal for surgical treatment of primary hyperparathyroidism.
