    ABSTRACT: A man aged 80 and three women aged 66, 26, and 39 years respectively, underwent surgery for Graves' disease. The first woman had pneumonia and experienced thyrotoxic storm. Euthyroidism was restored with antithyroid drugs (ATD) and thyroidectomy was performed as ablative treatment for hyperthyroidism. The man presented with thyrotoxicosis and had severe Graves' ophthalmopathy. After euthyroidism was restored with ATD, he underwent subtotal thyroidectomy. The second woman presented with severe thyrotoxicosis but was allergic to ATD. She was treated with iodine and beta-blockers after which subtotal thyroidectomy was done as an ablative procedure. Medical treatment for hyperthyroidism failed in the last patient and, as she had experienced severe psychological disturbances during a previous relapse, she too chose surgery as a definitive treatment option. In two patients the postoperative course was complicated by early hypocalcaemia and one of these patients experienced temporary recurrent laryngeal nerve paralysis. Surgery has a limited role in the treatment of Graves' disease. In pregnant women with severe ATD-resistant thyrotoxicosis, surgery is the only treatment option, while in patients with Graves' orbitopathy surgery may be preferable because of its neutral and perhaps even beneficial effects on eye symptoms. Large goitre size and thyroid nodules are concomitant reasons for choosing surgery, as are allergy to ATD and patients' preference. Lastly, in patients who have suffered from severe thyrotoxicosis, surgery provides rapid and definitive treatment. Early morbidity following surgery is common and should be discussed with the patient.

    ABSTRACT: To evaluate the results of minimally-invasive parathyroidectomy without the use of intraoperative parathyroid-hormone assessment or a gamma probe. Retrospective. In 2 community hospitals in the Netherlands, 49 patients with primary hyperparathyroidism in whom preoperative investigations had shown a solitary adenoma underwent minimally-invasive surgery by the lateral neck approach. In total 9 men and 40 women with an average age of 58 years (limits: 25-84) underwent this procedure. More extensive preoperative investigations were carried out at the Mesos Medisch Centrum (n = 29) including neck CT in 76% of patients as well as ultrasonography, and scintigraphy. At the Diakonessenhuis (n = 20) scintigraphy was the preferred method of adenoma localisation. Intraoperative parathyroidhormone assessment and a gamma probe were not used in the operative procedure. At the Diakonessenhuis intraoperative frozen-section investigations were done. In 44 of the 49 patients (90%) minimally-invasive parathyroidectomy resulted in normocalcaemia. In the remaining 5 patients a second procedure was necessary--a conventional neck exploration and also resulted in normocalcaemia. In 2 of these patients the adenomas had been missed during first procedure by the surgeon, while in 3 other patients preoperative examinations were falsely positive in the sense that the adenoma proved to be present but in an area other than that indicated by preoperative imaging. Permanent recurrent laryngeal-nerve paralysis complicated the postoperative course in 2 patients. The success rate of the minimally-invasive operation was the same for both groups. Without the use of intraoperative parathyroid-hormone assessment or a gamma probe minimally-invasive parathyroidectomy was successful in 90% of patients.
