Minimally invasive radioguided parathyroidectomy (MIRP).

The technique of parathyroidectomy has traditionally involved a bilateral exploration of the neck with the intent of visualizing 4 parathyroid glands and resecting pathologically enlarged glands. Parathyroid scanning using technetium-99m sestamibi has evolved and can now localize 80% to 90% of parathyroid adenomas. The technique of minimally invasive radioguided parathyroidectomy (MIRP) is a surgical option for most patients with primary hyperparathyroidism and a positive preoperative parathyroid scan. The technique makes use of a hand-held gamma probe that is used intraoperatively to guide the dissection in a highly directed manner with the procedure often performed under local anesthesia. The technique results in excellent cure rates while allowing most patients to leave the hospital within a few hours after the completion of the procedure. Current data also suggest the procedure can decrease hospital charges by approximately 50%. This technique may significantly change the management of primary hyperparathyroidism.
