Minimally invasive parathyroidectomy utilizing a gamma detecting probe intraoperatively.

The most common pathologic finding in primary hyperparathyroidism is a single adenoma. Traditionally, all four glands have been explored during surgery for primary hyperparathyroidism. With the advent of accurate localizing diagnostic studies, such as the sestamibi scan, some surgeons are now recommending single-gland exploration. In addition, when a sestamibi scan is performed the day of surgery, a gamma detecting probe can be used intraoperatively to direct the dissection. Although an experienced surgeon will successfully locate the abnormal gland 95% of the time with the traditional approach, this new technique results in a smaller incision with better cosmetic results as well as decreased operative time. Our initial experience with eight cases utilizing this technique is presented.
