Surgical Experience of Primary Hyperparathyroidism: Analysis of Postoperative Outcomes

Abstract

Background and Objectives The standard surgical procedure for primary hyperparathyroidism is the bilateral exploration. However, the unilateral exploration and direct focused parathyroidectomy have been performed to reduce surgical morbidity. The purpose of this study was to report the surgical outcomes and efficacy of the bilateral exploration, unilateral exploration, and direct focused approaches for primary hyperparathyroidism. Subjects and Method We retrospectively analyzed the surgical outcomes of 87 patients with primary hyperparathyroidism from January 2007 to December 2017. We compared the operative time, complication and recurrence rate between the three operative methods. Results The most common histopathology was parathyroid adenoma, which was found in 73 cases (83.9%), followed by hyperplasia. In terms of complications, there were two cases of transient vocal cord palsy, one case of hematoma, one case of hypocalcemia and one case of hungry bone syndrome. Recurrence occurred in two (2.3%) out of 87 cases. There was no significant difference in the recurrence rate between the three surgical approaches. Conclusion The success rate of surgery for primary hyperparathyroidism is high. Direct focused parathyroidectomy may be a good option for parathyroid adenoma if the localization tests localize the lesion. The bilateral exploration is effective for parathyroid hyperplasia.
