title: Video-assisted neck exploration for primary and secondary hyperparathyroidism: initial experience.
abstract: BACKGROUND
  Minimally invasive surgery (MIS) for primary hyperparathyroidism includes unilateral neck exploration, access via a totally endoscopic approach, and access via a video-assisted procedure. We report herein our initial experience with the video-assisted neck exploration procedure for primary (PHPT) and secondary hyperparathyroidism (SHPT).
  
  
  METHODS
  Between June 1999 and May 2000, 35 patients were selected for PHPT (n = 25) and SHPT (n = 10). In all cases, video-assisted neck exploration was performed under general anesthesia, leading to selective adenoma removal in PHPT or subtotal parathyroid resection in SHPT. Patient selection was based on the preoperative localization studies (ultrasonography and sestamibi scintigraphy).
  
  
  RESULTS
  Five of the 25 patients operated on for PHPT (20%) and three of the 10 patients who underwent surgery for SHPT (30 %) were converted to a conventional surgical technique. The mean operative times in PHPT and SHPT were 48.9 +/- 18.7 min and 136.8 +/- 18.7 min, respectively. The recurrent laryngeal nerve was identified in 45% of the patients. The median size and weight of the resected parathyroid glands were 1.8 cm (range, 0.9-2.5) and 1 g (range, 0.5-7), respectively. The length of skin incision was 24 +/- 1.2 mm. All but one patient are currently cured, with a median follow-up of 6 months (range, 2-13). Postoperative complications included hematoma and transient hoarseness in one patient each (2.85%). The median pain intensity, based on the visual analogue scale (VAS) method, as measured at postoperative day 1 was 0.5 (range, 0-3.6). In the PHPT group, the postoperative hospital stay was
