Abstract

• Forty-five patients with biochemically documented primary hyperparathyroidism as part of multiple endocrine neoplasia syndrome types 1 or 2 were surgically treated from 1960 through 1980. Hyperplasia occurred in 69% of the patients, single adenoma in 27%, and double adenomas in 4%. All but two patients with hyperplasia underwent subtotal parathyroidectomy. In this group, the cure rate was 93% and the incidence of permanent postoperative hypoparathyroidism 23%. In the adenoma group, treatment included excision of the adenoma and biopsy of at least one other gland. The cure rate was 76%, with no postoperative hypoparathyroidism. Analysis of patients with persistent hyperparathyroidism suggested that failure to recognize multiple gland disease was the principal cause of postoperative hypercalcemia. In view of the high incidence of hypocalcemia after subtotal parathyroidectomy, approximately 500 mg of tissue should be cryopreserved to allow transplantation should hypocalcemia ensue postoperatively.
