Primary hyperparathyroidism in the 1990s. Choice of surgical procedures for this disease.

Abstract：

:Many advances have occurred in recent years in the diagnosis, localization, and treatment of primary hyperparathyroidism. Several different operative choices for primary hyperparathyroidism also have been proposed--a unilateral approach versus the standard bilateral parathyroid exploration. The unilateral approach is based on the concept that if an enlarged parathyroid gland and a normal gland are found on the first side of the neck that is explored, then this is an adenoma and the second side should not be explored. Only if both glands on the initial side are recognized to be abnormal is the second side explored. The theoretical advantages of this unilateral approach are a decrease in operative morbidity rates--hypoparathyroidism and nerve injuries--and a decrease in operative time. Furthermore, proponents argue that if persistent hyperparathyroidism occurs, the second side can be easily explored because it was previously untouched. In the hands of several expert parathyroid surgeons, excellent results have been achieved. However, the unilateral approach has a number of disadvantages. It places considerable pressure on the surgeon and pathologist, for they have only one parathyroid gland other than the large one to examine. There is a significant potential risk of missing double adenomas or asymmetric hyperplasia because the second, ipsilateral parathyroid gland may appear normal or near normal in these conditions. This could lead to an increased incidence of persistent or recurrent hyperparathyroidism. Furthermore, a significant reduction of operative time may be questioned, especially when the time for performing special fat stains, which often are performed with unilateral explorations, is added. Finally, even if the intent is to perform a unilateral exploration, a bilateral exploration will be necessary about half of the time. The authors strongly recommend a bilateral parathyroid exploration for all patients undergoing an initial parathyroid operation. In cases of adenoma, bilateral visualization of normal parathyroid glands and careful biopsy of only one of them will minimize hypoparathyroidism. This operative approach will lead to better results, especially for the less experienced parathyroid surgeon.
