ObjectiveTo evaluated the effect of the video-assisted thoracoscope surgery(VATS) for non-small cell lung cancer. MethodsWe searched EMbase, PubMed, OVID, Springer Link, Cochrane Library, CNKI, CBMdisc, and VIP to collect randomized controlled trials(RCTs) of VATS versus thoracotomy for non-small cell lung cancer. Each database was searched from establishment to October 2014. Two reviewers independently assessed the quality of the included studies and extracted relevant data, using RevMan5.3 meta-analysis software. ResultsWe finally identified 10 RCTs involving 1 529 patients. There were 453 patients in the VATS group and 1 076 patients in the thoracotomy group. The results of meta-analysis showed that there was no statistical difference in the number of lymph node dissection(P=0.41), operation time(P=0.14), operation bleeding volume(P=0.14), chest tube placement time(P=0.53), operation mortality(P=0.72), and the overall survival rate(P=0.39). While there were statistical differences in thoracic drainage(P=0.04), post-operation hospital stay(P=0.01), and postoperative complications(P=0.0001). ConclusionVATS is safe and effective in the treatment of non-small cell lung cancer.
Objective To analyze clinical outcome of the technique of comprehensive aortic root and valve reconstruction (CARVAR) applying in aortic valve and root disease. Methods We retrospectively analyzed the clinical data of 106 patients with aortic valve and root disease underwent CARVAR technique in our hospital from July 2012 to July 2015. There were 72 males and 34 females at the average age of 57.3 (11-67) years. We operated the CARVAR technique and analyzed the early and midterm clinical outcomes. Results There was no mortality and low cardiac output syndrome postoperatively. But there were 2 cases of renal insufficiency or failure and 1 case of infective endocarditis. The average ejection fraction was 54%. The mean area of aortic valve orifice was 2.2±0.8 cm2. The aortic valve pressure gradient was 11.2±2.3 mm Hg. There were 2 cases of mild aortic valve regurgitation. The result of operation was satisfying with a stable hemodynamics and few complications. The follow-up after surgery showed that there was no obvious abnormity in aortic valve and root. Conclusion Using CARVAR technique to cure aortic valve and root disease is an effective treatment and it can achieve satisfactory early and midterm clinical outcomes.
