title: Does concomitant thyroidectomy increase risks of parathyroidectomy?
abstract: Concomitant thyroid pathology in patients with primary hyperparathyroidism is common. This study compares complications of patients who underwent parathyroidectomy to those who underwent parathyroidectomy with a concomitant thyroidectomy.
  
  
  
  A retrospective review of prospectively collected data on 709 patients who underwent parathyroidectomy was performed. Patients who had prior thyroid or parathyroid procedures were excluded. Chi-square, Fisher's exact, Student's t-test, and Wilcoxon rank-sum tests were used to compare cohorts.
  
  
  
  Of the 641 patients included, 90% underwent parathyroidectomy alone and 10% underwent parathyroidectomy with a concomitant thyroidectomy. Overall, 49% had preoperative thyroid disease and 22% of patients with thyroid disease had a thyroid procedure. When compared with parathyroidectomy alone, parathyroidectomy with a concomitant thyroidectomy was associated with longer operative times (91 min versus 57 min, P < 0.001), increased rate of overnight stay (69% versus 17%, P < 0.001), and increased rate of transient hypocalcemia (15% versus 3%, P < 0.001).
  
  
  
  Parathyroidectomy with a concomitant thyroidectomy is associated with longer operative times, increased rate of overnight stay, and increased transient hypocalcemia.
