Normocalcemic hyperparathyroidism: preoperatively a disease, postoperatively cured? - 05/05/14
Abstract |
Background |
Up to 44% of primary hyperparathyroidism patients have elevated parathyroid hormone (ePTH) with normal calcium postparathyroidectomy (PTx). The question is whether the surgical approach affects the incidence of this phenomenon.
Methods |
Patients with hyperparathyroidism and presumed single-gland disease on preoperative imaging who underwent PTx between 1994 and 2008 were identified and contacted for long-term follow-up. PTx was either a focused approach (minimally invasive approach [MIP]) or a bilateral neck exploration (BNE).
Results |
In total, 171 patients had PTH measured postoperatively (95 MIP and 76 BNE); 30 of 171 (17%) had ePTH with normal calcium (MIP 21 [22%] and BNE 9 [12%], P = .08). This occurred within 2 years in 48% and 67% and after 2 years in 52% and 33%, MIP vs BNE, respectively. Four patients recurred, 2 MIP and 2 BNE.
Conclusions |
There is a trend toward a higher incidence of ePTH in patients having undergone an MIP. The etiology of ePTH is multifactorial but may represent an early recurrence.
