Background
The aim of this study was to determine whether a focused minimally invasive parathyroidectomy (MIP) for patients with primary hyperparathyroidism and concordant pre-operative localization studies is appropriate for patients with a family history of the disease. Familial hyperparathyroidism may be seen as a chronic disease in which recurrence is inevitable. Patients frequently undergo subtotal or total parathyroidectomy for perceived 4-gland parathyroid hyperplasia in an attempt to reduce this risk. Controversy remains regarding whether a MIP is appropriate in this setting.
Methods
Patients undergoing an MIP were identified from prospectively maintained databases. Chart review confirmed the presence of a family history of hyperparathyroidism in a direct relative. Patients with and without a family history were compared regarding overall complications, recurrence, and cure rates.
Results
A total of 1,652 patients underwent a MIP. Of these, 34 patients had a positive family history. There was no statistically significant difference in age, gender, preoperative biochemistry, gland weight, or complication rates between the groups. The cure rate at 6 months from a single operation was equivalent between the 2 groups (97 vs. 98%). With a median of 39 months follow-up, the recurrence rate was higher in those with a family history compared with those without (8.8 vs 1.1%; P = 0.002). Reoperation was successful in the small population of familial patients who did present with recurrent hyperparathyroidism.
Conclusions
The vast majority of patients who underwent a MIP were surgically cured. Although recurrence rates remain higher in the familial hyperparathyroidism group, these data suggest that this alone should not be a contraindication to MIP.
