title: Videothoracoscopy in the treatment of benign neurogenic tumours of the posterior mediastinum.
abstract: BACKGROUND
  The indications for videothoracoscopy are very broad and include the treatment of mediastinal tumours.
  
  
  OBJECTIVE
  To present our experience of using the minimally invasive technique in treating benign neurogenic tumours.
  
  
  METHODS
  Twenty-two patients were treated due to tumours of the posterior mediastinum from 2003 to 2012. The size of the tumours ranged from 2 cm to 25 cm. Tumours up to the size of 6 cm were treated using videothoracoscopy (VT), bigger ones through thoracotomy.
  
  
  RESULTS
  The videothoracoscopy technique was used in 17 patients, thoracotomy in 5. In 2 cases conversion was required due to adhesions in the pleural cavity preventing VT treatment. Complications related to the procedure were not observed. The average time of hospital stay after VT treatment was 4 days, while after thoracotomy it was 6 days. Histologically, tumours of benign nature were found in all cases. Schwannoma was diagnosed in 15 patients, ganglioneuroma in 3 patients, neurofibroma in 3 patients, and chemodectoma in 1 patient. None of the 3 cases of neurofibroma was associated with Recklinghausen's disease. At a mean follow-up of 60 months no recurrence of the tumour was found.
  
  
  CONCLUSIONS
  In the case of tumours up to 6 cm the best surgical technique is videothoracoscopy. In the case of large tumours the best access is the open technique. The minimally invasive technique allows one to shorten the patient's treatment time, reduce postoperative pain and obtain a good cosmetic effect of the treatment.
