Is Confirmation of Parathyroid Tissue by Frozen Section Superior to Localization of Solitary Parathyroid Adenoma Using Intraoperative Gamma Probe Survey? A Retrospective Cohort Study

Context. In the surgical treatment of primary hyperparathyroidism, intraoperative localization of the diseased glands is an essential issue. We aimed to evaluate the impact of the intraoperative frozen section during radio-guided focused parathyroidectomy and compare its efficiency with intraoperative gamma probe survey and measurement of intraoperative quick parathyroid hormone. Methods. All consecutive patients underwent radio-guided focused parathyroidectomy for primary hyperparathyroidism due to solitary parathyroid adenoma. The outcomes of parathyroidectomy were evaluated by serum levels of calcium and parathyroid hormone. The primary outcome was the surgical cure diagnosed by normal serum calcium levels in the sixth postoperative month. Results. A total of 55 patients with a mean age of 54.3±12.2 years were evaluated. The diagnostic accuracy of the preoperative localization tests was calculated as 92.7%. The intraoperative gamma probe survey impacted the operative plans of four patients (7.3%) by localizing the diseased gland in other positions. The accuracy of intraoperative quick parathyroid hormone and frozen section analysis was 100% for both. In all patients, serum calcium and PTH levels dropped to normal in the sixth postoperative month. There were no cases of the persistent or recurrent disease during the follow-up period. Conclusion. The results of the intraoperative gamma probe survey, intraoperative quick parathyroid hormone, and frozen section were concordant with the final pathology in all cases. In four patients (7.3%), intraoperative gamma probe survey impacted the operative plans. The intraoperative gamma probe survey may be used as the sole intraoperative method to locate the correct position of the solitary parathyroid adenoma.
