title: Minimally invasive video-assisted parathyroidectomy is a safe procedure to treat primary hyperparathyroidism.
abstract: BACKGROUND
  Cervical exploration to identify the four parathyroid glands was considered to be the gold standard for management of primary hyperparathyroidism. In recent years, advances in preoperative localizing techniques have led to the use of more targeted, minimally invasive procedures to remove parathyroid glands. We present our series of patients who underwent Minimally Invasive Video-Assisted Parathyroidectomy (MIVAP) procedures and our results in treating primary hyperparathyroidism.
  
  
  METHODS
  Patients who underwent video-assisted parathyroidectomy were identified from a prospectively maintained database. Clinico-pathological data including indications for surgery, complications, conversion to open procedure and success of surgery were obtained from clinical notes.
  
  
  RESULTS
  A total of 56 patients underwent MIVAP between 2002 and 2010 at a district general hospital setup. The clinical indication was diagnosed primary hyperparathyroidism. Preoperative localization was attempted in all patients by sestamibi and high resolution ultrasound scans. The median age of patients was 65 years (32-82) and the median operating time was 78 min (20-168). Conversion to open procedure was done in 8/56 (14%) cases. The reason for conversion was failed exploration in 5 patients, inability to retrieve a very large friable adenoma in one patient, lipo-adenoma in one patient and very small parathyroid adenoma in one patient. Postoperative complications happened in one patient (2%) who developed postoperative sepsis resulting in temporary recurrent laryngeal nerve (RLN) palsy. All but 5 patients became normo-calcaemic following surgery.
  
  
  CONCLUSIONS
  MIVAP is a safe and effective procedure for treating patients with primary hyperparathyroidism. It also allows classical 4 gland exploration, whenever necessary.
