ObjectiveTo systematically evaluate the effectiveness, safety and ethics of Da Vinci Surigcal System (dVSS)in the field of cardiothoracic surgery, and provide evidence for its clinical application. MethodsWe searched VIP, CNKI, WanFang Database, CBM, official website of National Health and Family Planning Commission of People's Republic of China, PubMed, Cochrane Library, Google Scholar, WHO ICTRP search portal, ClinicalTrials.gov, Chinese Clinical Trial Registration Center, Australian-New Zealand Clinical Trials Registry and ISRCTN to collect clinical trials of dVSS for thoracic and cardiovascular diseases to evaluate its effectiveness, safety and ethics. The search time was from the establishment of each database to January 2014. The quality of included literatures was evaluated by Grades of Recommendations Assessment, Development and Evaluation (GRADE). ResultsA total of 31 studies were identified including 4 case control studies and 27 retrospective studies involving 1 037 patients. The quality of included literatures was all very low. dVSS had been widely used in cardiothoracic surgery including coronary artery bypass grafting, valvuloplasty or valve replacement, thoracic tumor resection, etc. Compared with conventional surgery and thoracoscopy, the safety and effectiveness of dVSS was good, while its economic burden was heavier for the patients. dVSS could benefit patients and improve clinical level of cardiothoracic surgery. The disciplines and qualification of dVSS application was legal, but the maturity of its clinical use needed improvement, and relevant measures were required. The ethics in the research, introduction and application of dVSS had some problems which deserved more attention. ConclusionsClinical use of dVSS in cardiothoracic surgery is relatively safe and effective, but research quality needs to be improved. More studies on the economics and ethics of dVSS are needed in the field of cardiothoracic surgery. Relevant measures of precaution, accountability and patient protection are required to further improve clinical application of dVSS in cardiothoracic surgery, and whole-process ethical supervision should be conducted with the help of existing clinical ethical review platform.
ObjectiveTo evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with pulmonary lobectomy. MethodsWe retrospectively analyzed the clinical data of 50 patients in General Hospital of Shenyang Military Region of Thoracic Surgery between May 2012 and March 2015.The patients were divided into two groups. Twenty five patients aged over 70 years underwent radical operation of lung cancer with da Vinci Robot System were allocated into a robot group with 17 males and 8 females at age of 72.6 ±2.5 years. Another 25 senile patients with radical surgery by video-assisted thoracoscopic surgery (VATS) were allocated into a thoracoscopic group with 17 males and 8 females at age of 72.5±2.4 years. The patients in the two groups underwent pulmonary lobectomy and mediastinal lymph node dissection. The clinical effect of the two groups was compared. ResultsAll patients were diagnosed as lung cancer. Twenty five patients all completed surgery under da Vinci Robot System in the robot group. In the thoracoscopic group, one patient was converted to thoracotomy. There were statistical differences in amount of blood loss (66.2±44.2 ml vs. 356.0±349.2 ml, P=0.000), lymph node number (23.2±9.8 vs. 11.3±5.6, P=0.012), and postoperative bed time (3.5±0.9 d vs. 4.2±1.1 d, P=0.017) between the two groups. Effect in the robot group was superior to that in the thoracoscopic group. ConclusionDa Vinci robotic surgery system for elderly patients with lung cancer radical surgery is safe, effective, and less thoracoscopic surgery trauma, recovery faster.
