title: Minimally invasive, video-assisted thyroidectomy: first experience from the United Kingdom.
abstract: BACKGROUND
  Minimally-invasive, video-assisted thyroidectomy (MIVAT) was developed to reduce scarring/trauma associated with cervical incisions used in open thyroidectomy. Results from various centres have been published internationally but none from the UK. This study reports the first results from the UK and compares them with other centres. We also aim to compare the results of a single-surgeon experience in a small/moderately-sized hospital to those of larger tertiary centres.
  
  
  METHODS
  Retrospective analysis of a single surgeon experience in a district general hospital
  
  
  RESULTS
  The cohort was 55 patients (52 female, 3 male), mean age 48 years (range, 21-77 years) who had 64 MIVAT procedures. There were 49 hemithyroidectomies (HTs), 2 isthmusectomy, 4 total thyroidectomies (TTs) and 9 completion thyroidectomies (CTs) with median operating time of 86 min (IQR 66-110 min). Individual operating times were HT 85 min (IQR 60-110 min); TT 130 min (IQR 100-140 min) and CT 77 min (IQR 70-98 min). Median operating time was shorter in the second half of this series (76 min vs 92 min; P < 0.001). Length of stay was < 1 day in 92%. Conversions occurred in 6.3% with no haematoma or re-operation. Transient voice change was present in 7 (11%), permanent unilateral recurrent laryngeal nerve palsy in 2 (3%), and transient hypocalcaemia in 2 (3%).
  
  
  CONCLUSIONS
  The first results from the UK are similar to those of other international centres. A single-surgeon practice can obtain results comparable to larger tertiary centres provided there is sufficient case-load. MIVAT is safe and effective, but has a steep learning curve with rapid improvement observed within first 30 cases. Future studies should focus on objective assessment of scar/cosmesis and cost-effectiveness. MIVAT is an acceptable alternative to open surgery in highly selected patients.
