Abstract: Objective To explore the surgical experience of single utility port video-assisted thoracoscopic lobectomy on peripheral lung cancer.Methods Fiftytwo patients with peripheral lung cancer underwent radical resection urder single utility port completely video-assisted thoracoscopy.Operation time，intraoperative occurrence，postoperative complications，length of stay and other data were recorded.Results All the procedures were carried out with no case of death.Conversions to thoracotomy were required in 2 cases.Except these converted to thoracotomy，the surgical duration of 50 cases was 105～220min[mean，（152.6±33.1）min].The volume of intraoperative bleeding was 20～400ml[mean，（160.4±81.5）ml].There was no serious postoperative complications，2 cases of patients with chylothorax cured by conservative treatment.The postoperative hospitalization time was 7～14d[mean，（9.7±1.7）d].Conclusion The operative procedure of radical resection of lung cancer urder single utility port video-assisted thoracoscopy is still being explored and optimized.Individualized operation path should be chosen according to the difference of patients.
