title: [Minimally-invasive parathyroidectomy: a good operative procedure for primary hyperparathyroidism even without the use of intraoperative parathyroid-hormone assessment or a gamma probe].
abstract: OBJECTIVE
  To evaluate the results of minimally-invasive parathyroidectomy without the use of intraoperative parathyroid-hormone assessment or a gamma probe.
  
  
  METHODS
  Retrospective.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Without the use of intraoperative parathyroid-hormone assessment or a gamma probe minimally-invasive parathyroidectomy was successful in 90% of patients.
