Objective: In this research, we aimed to evaluate the success of the minimally invasive surgical method performed with intraoperative gamma-probe despite early wash-out in solitary primary parathyroid lesions and to contribute to the literature on this subject.

Methods: This retrospective study included 48 adult patients diagnosed with hyperparathyroidism, with an average parathormone value of 105 pg/mL (range: 82-127 pg/mL). Radionuclide imaging was conducted using Tc-99m sestamibi and Tc-99m-pertechnetate. Minimally invasive surgery with an intraoperative gamma probe was planned for patients with primary parathyroid lesions and surgical indications. At the conclusion of the operation, count equalization was observed in all four quadrants.

Results: Minimally invasive surgery was performed on 42 patients with the assistance of an intraoperative gamma probe. In 6 patients, the procedure was extended to conduct a four-gland exploration due to early wash-out. Each patient had one pathological lesion removed, all of which were histopathologically confirmed as parathyroid adenomas. Among the 6 patients with extended surgeries, 4 experienced early wash-out, and all 6 had been diagnosed with multinodular goiter.

Conclusion: In cases with primary hyperparathyroidism, it is aimed to remove the pathological lesion with minimally invasive surgery and leave the glands that continue their normal function in place. Preoperative localization methods help the surgeon in this regard, but pathologies in the surrounding tissue can reduce the success of minimally invasive surgery.
