title: [Clinical study of lymphadenectomy of lung cancer by video-assisted thoracic small incision surgery].
abstract: OBJECTIVE
  To study the clinical efficacy of lymphadenectomy of lung cancer by video-assisted thoracic small incision surgery.
  
  
  METHODS
  Radical lobectomy or pneumonectomy and systemic lymphadenectomy were performed in 197 patients with NSCLC through video-assisted thoracoscopic surgery. Pathological type and grade, total number of dissected lymph nodes, number of metastatic lymph nodes, survival and life quality were evaluated.
  
  
  RESULTS
  The average of dissected lymph nodes was 11.61 and 471 lymph nodes from 382 regions were confirmed to have metastasis. The metastatic rates were 24.1% and 20.6% respectively. There were no significant difference between video-assisted thoracic small incision surgery and conventional thoracotomy. The 1, 3, 5-year survival rates of stage I , II and III a had no significant difference between video-assisted thoracic small incision surgery and conventional thoracotomy.
  
  
  CONCLUSIONS
  Video-assisted thoracic small incision surgery achieves a similar efficacy as the traditional lymphadenectomy and lung cancer radical resection.
