title: Surgical strategy in hyperparathyroidism due to solitary adenoma.
abstract: Based on the postulate that parathyroid adenoma is practically always a solitary lesion, unilateral parathyroidectomy including the homolateral normal parathyroid was applied as a principle in the treatment of this form of primary hyperparathyroidism. The exploration was confined to the adenoma side if this was the first to be explored. Intraoperative oil-red-O staining of frozen sections was used to exclude the possibility of a multiglandular involvement. This principle was applied in a consecutive series of 102 patients operated for hyperparathyroidism from 1977 to 1981 and diagnosed as parathyroid adenoma. In 43 patients where the abnormal gland was found on the side explored first, unilateral parathyroidectomy was performed on that side, avoiding exploration of the contralateral side. In 45 patients where normal glands were found on the side first explored, unilateral parathyroidectomy was performed on the contralateral side. In 14 patients other types of operations were performed as the above-mentioned principle could not be achieved. At follow-up 1 to 5 years after surgery, no cases of hypocalcemia were recorded. The results of the different operations were compared as to early and late hypocalcemia. Early hypercalcemia was more pronounced after a bilateral exploration. Two of the patients who had an atypical operation had a permanent need for vitamin D in order to maintain an adequate serum calcium level. Surgical principles for various possible exploratory findings are outlined. These are based upon the idea of performing a unilateral parathyroidectomy whenever intraoperative oil-red-O staining excludes multiglandular involvement as a cause for the hyperparathyroidism.
