title: [Effects and reasons of conversion during video-assisted thoracic surgery lobectomy].
abstract: OBJECTIVE
  To explore the impact and reasons of conversion during video-assisted thoracic surgery (VATS) lobectomy.
  
  
  METHODS
  A total of 374 patients undergoing VATS lobectomy during May 2007 and May 2012 were divided into 2 groups according to whether conversion was necessary. And their clinical data were retrospectively analyzed.
  
  
  RESULTS
  Among them, 36 cases (9.6%) converted into thoractomy during VATS lobectomy. Their clinical profiles of age, gender and surgical type were similar. The conversion group had longer operative duration, more blood loss and more benign proportion than VATS group.No inter-group difference existed in postoperative complication, mortality; tube removal time or hospitalization length. The reasons of conversion included hemorrhage (n = 12), vascular adhesion (n = 6), instrumentation complication (n = 5), incomplete fissure (n = 5), uncertain anatomy (n = 3), abnormal blood vessels (n = 3) and insufficient margin (n = 2).
  
  
  CONCLUSIONS
  Conversion during VATS lobectomy may prolong operative duration and increase blood loss.However there is no effect upon patient recovery.
