[Surgery of primary hyperparathyroidism by unilateral approach under local anesthesia and peroperative assay of 1-84 parathyroid hormone].

By combining echography and per-operative hormone assay, surgery for primary hyperparathyroidism due to a single adenoma can be performed via a limited unilateral access route with local anaesthesia. In a recent series of 204 patients, this technique was not contraindicated in 88 (43%). The operation was successful in 81 of these (92%). In 8 cases, the operation had to be converted into bilateral cervicotomy under general anaesthesia. Six of them were successful. The overall cure rate was 98%. Peroperative assay of 1-84 parathyroid hormone is an essential element in this technique.
