Objective
To evaluate the results of a modern surgical approach in patients with primary hyperparathyroidism.
Design
Retrospective analysis.
Setting
University hospital, tertiary care center.
Patients
One hundred patients consecutively operated on for suspected primary hyperparathyroidism. Patients were available for follow-up 1 month (n=100) and 1 year (n=96) after surgery.
Intervention
Cervical exploration. Surgical strategy was to remove enlarged parathyroid glands only and perform a biopsy on no more than one normal gland.
Main Outcome Measures
Surgical morbidity and normocalcemia.
Results
No operative mortality or wound infection occurred in any patient. Postoperative vocal cord paralysis was recorded in two patients; both recovered fully. Two patients underwent a second operation. (One patient experienced subcutaneous bleeding and the second patient, previously operated on for toxic goiter, experienced persistent hypercalcemia and was operated on 5 days after the initial operation. A second abnormal gland was then found on the contralateral side, not initially surgically explored.) At follow-up, 97 patients were normocalcemic; three patients had hypoparathyroidism: two of these patients, with multiglandular disease, were normocalcemic and received a low dose of vitamin D (1
[OH]D3), and one patient, who had had a single adenoma removed, was slightly hypocalcemic, however, asymptomatic.
Conclusions
More than 90% of patients with primary hyperparathyroidism can be operated on without complications occurring. This supports a liberal attitude to operation.
