title: Minimally invasive video-assisted parathyroidectomy (MIVAP) for secondary hyperparathyroidism: report of initial experience.
abstract: BACKGROUND
  Minimally invasive video-assisted parathyroidectomy (MIVAP) has become a well-accepted procedure for patients with primary hyperparathyroidism. Because it allows bilateral neck exploration, the authors began using this technique for patients with secondary hyperparathyroidism. In this preliminary study, the authors report their initial experience.
  
  
  METHODS
  From July 2006 to November 2008, 12 patients (6 women, 6 men; mean age, 45.5 +/- 16.9 years (range, 23-71 years) underwent MIVAP with bilateral exploration for secondary hyperparathyroidism. The operation was performed through a central 2-cm to 3-cm skin incision; a 30 degrees 5-mm endoscope was used for magnification.
  
  
  RESULTS
  MIVAP was successfully completed in 11 patients (92%). The mean operative time was 81 +/- 37 minutes (range, 35-130 minutes). No major complications were registered. After a mean follow-up period of 11.4 months (range, 3-30 months), 1 patient showed recurrence.
  
  
  CONCLUSIONS
  MIVAP appears to be a safe and feasible procedure in patients with secondary hyperparathyroidism.
