    Abstract:
    The majority of patients affected by primary hyperparathyroidism present now in surgical series are little or totally asymptomatic. This is due to widespread use of multiphasic screening for hypercalcemia as far as to more liberal indications for parathyroid exploration. The debate about the need for parathyroidectomy is open in these patients, having few or no signs at all of primary hyperparathyroidism, because conservative treatment has yielded confused results. The authors analyzed preoperative biochemical values and surgical outcome from 26 patients affected by primary hyperparathyroidism. Thirteen cases had overt primary hyperparathyroidism (group A) and 13 had asymptomatic disease (group B). Patients in group A had higher preoperative PTH values than patients in group (p < 0.05). After surgery, the patients in group A showed parathyroid glands which weighted significatively more than ones in group B (p +/- 0.01). Further, a significant correlation between preoperative PTH value and glandular weight was demonstrated in all cases. The authors conclude surgery for patients having mild primary hyperparathyroidism may give some problems related to the very small size of abnormal glands found during operation. We advise a close follow-up for these patients initially without treatment: surgery should be recommended for those showing PTH values higher than 150 pg/ml.
