Study Design
A retrospective analysis of all patients who underwent parathyroidectomy for primary hyperparathyroidism at a university-affiliated tertiary care center between 2004-2019 was performed. Patients were followed for a minimum of 6 months. Subsequently, a comparison of the cure rates (normalization of serum calcium levels at 6 months post-surgery) was made between patients who underwent parathyroidectomy with IOPTH and those who underwent parathyroidectomy without IOPTH. Only patients who underwent focused parathyroidectomy were included in the study. Operating room time was also compared between the two groups.
The study was approved by the Institutional Review Board.
