  • Title: [Primary hyperthyroidism 1996].
    Author: Schweizer I, Bleisch JA, Gemsenjäger E.

    Abstract:
    55 prospectively documented patients aged 20-84 (median 67) years (47 women, 8 males) underwent surgery for primary hyperparathyroidism (pHPT). The most frequent symptoms and associated conditions were nephrolithiasis (42%) and neuropsychiatric symptoms (39%). Only one case of asymptomatic and one case of "normocalcemic" pHPT were found in this series. 47 patients (89%) were cured following initial neck exploration, and 3 further patients (6%) were cured by a second operation. Reoperation also led to cure in 2 patients operated on elsewhere in the first instance. 6 patients (11%) had double adenoma (bilaterally) and 36% of the adenomas had an ectopic location, with an intrathyroidal adenoma in 2 cases. In 2 patients sternotomy was carried out. Persistent pHPT was observed in 3 patients (following initial exploration in 2 cases and reoperation in one). These patients had a supernumerary adenomatous gland with ectopic location in 2 cases and a double adenoma with ectopic position of one adenoma in a further case. One 80-year-old patient died post-operatively from intestinal ischemia. 2 patients had permanent postoperative hypoparathyroidism; in no case was a permanent recurrent laryngeal nerve palsy observed. Bilateral parathyroid exploration with thyroid mobilization by capsular dissection is the procedure of choice for pHPT. In 2 patients with the MEN 2A-syndrome and with medullary thyroid carcinoma thyroidectomy, lymphadenectomy and autotransplantation of normal parathyroids to the arm was performed, with normal parathyroid function in both cases.
