Abstract: Objective To study safety and clinical results of single utility port video-assisted thoracoscopic surgery(VATS)for lung cancer.Methods From September 2009 to Octomber 2011,183 lung cancer patients underwent lobectomy and dissection of systematic mediastinal lymph nodes with single utility port video-assisted thoracoscopic surgery.Results Of the 183 patients,38 left upper lobectomy,31 left lower lobectomy,53 underwent right upper lobectomy,16 right middle lobectomy,43 right lower lobectomy,2 bilobectomy.The procedure was successful in all patients with no patient transferred for open thoracotomy.The mean operative time was(136.7±29.2)min,the average number of dissected lymph nodes from each patient was 11.9.The lung cancer was classified as TNM stageⅠA,ⅠB,ⅡA,ⅡB,and ⅢA in 117,22,18,5 and 21 cases,respectively.No post-operative death occurred.The postoperative complications occurred in 12 cases,atelectasis 6 cases,arrhythmia 5 cases,and bleeding 1case.Conclusion Single utility portal VATS is technically safety to perform complete lobectomy and dissection of systematic mediastinal lymph nodes for lung cancer,and with the advantages of lower morbidity and rapid postoperative recovery.
