title: [Video-assisted parathyroidectomy: a series of 85 cases].
abstract: OBJECTIVE
  To verify the feasibility of video-assisted parathyroidectomy, set up the indications and report the results in a series of 85 patients.
  
  
  METHODS
  From 1997 to 1999, 85 patients affected by primary hyperparathyroidism due to single gland disease, with an adenoma smaller than 35 mm as demonstrated by preoperative imaging, were referred for video-assisted parathyroidectomy. There were 62 females and 23 males. Mean age was 53 years, (range 23-82). Video-assisted parathyroidectomy was associated with intra-operative PTH quick-assay. Calcium testing was controlled before leaving the hospital, 1 month and 3 months later, and postoperative laryngoscopy was performed in all patients.
  
  
  RESULTS
  There were five conversions to open cervicotomy: three due to a contra-lateral second adenoma, two because of an intrathyroidal adenoma. The mean operative time for video-assisted procedure was 59 minutes (range: 25-180). Circulating PTH levels 10 minutes after the removal of the affected gland(s) always dropped significantly, and pathological report confirmed the parathyroid nature of the specimens (mean diameter 13 mm, range 7-35). Morbidity consisted of five cases of transient hypocalcemia and one permanent laryngeal nerve paralysis. We registered no persistent or recurrent disease (mean follow-up 12.8 months, range 1-28).
  
  
  CONCLUSIONS
  Video-assisted parathyroidectomy is feasible, and its results are similar to those of traditional procedure, while it seems superior as regards postoperative course and aesthetic results. It also allows different strategical decisions even during operation (i.e. bilateral exploration or thyroid lobectomy) by the same approach.
