title: [A comparative study of Da Vinci robot system with video-assisted thoracoscopy in the surgical treatment of mediastinal lesions].
abstract: BACKGROUND
  In recent years, Da Vinci robot system applied in the treatment of intrathoracic surgery mediastinal diseases become more mature. The aim of this study is to summarize the clinical data about mediastinal lesions of General Hospital of Shenyang Military Region in the past 4 years, then to analyze the treatment effect and promising applications of da Vinci robot system in the surgical treatment of mediastinal lesions.
  
  
  METHODS
  203 cases of mediastinal lesions were collected from General Hospital of Shenyang Military Region between 2010 and 2013. These patients were divided into two groups da Vinci and video-assisted thoracoscopic surgery (VATS) according to the selection of the treatments. The time in surgery, intraoperative blood loss, postoperative drainage amount within three days after surgery, the period of bearing drainage tubes, hospital stays and hospitalization expense were then compared.
  
  
  RESULTS
  All patients were successfully operated, the postoperative recovery is good and there is no perioperative death. The different of the time in surgery between two groups is Robots group 82 (20-320) min and thoracoscopic group 89 (35-360) min (P>0.05). The intraoperative blood loss between two groups is robot group 10 (1-100) mL and thoracoscopic group 50 (3-1,500) mL. The postoperative drainage amount within three days after surgery between two groups is robot group 215 (0-2,220) mL and thoracoscopic group 350 (50-1,810) mL. The period of bearing drainage tubes after surgery between two groups is robot group 3 (0-10) d and thoracoscopic group: 5 (1-18) d. The difference of hospital stays between two groups is robot group 7 (2-15) d and thoracoscopic group 9 (2-50) d. The hospitalization expense between two groups is robot group (18,983.6±4,461.2) RMB and thoracoscopic group (9,351.9±2,076.3) RMB (All P<0.001).
  
  
  CONCLUSIONS
  The da Vinci robot system is safe and efficient in the treatment of mediastinal lesions compared with video-assisted thoracoscopic approach, even though its expense is higher.
