[Long-term results of surgery of primary hyperparathyroidism].

The late results of operation for primary hyperparathyroidism were analysed in 52 patients operated between 1971 and 1987. All patients have a minimal 5 years follow-up, and answered a mailed questionnaire concerning their present state of health and recent serum calcium level. Recurrent hypercalcemia occurred in 5.7%. Hypocalcemia occurred in 30% immediately after operation; in 11.5% at six months, and in 7.7% at the final follow-up. The pathogenesis of such hypocalcemia is discussed. 66% of patients with urinary calculi are cured after neck exploration and urologic procedure. Finally 86.6% of the patients are normocalcemic at the final follow up, acting for the efficient and lasting character of the surgical treatment in primary hyperparathyroidism.
