Background  While video-assisted thoracic surgery lobectomy has been widely accepted for the treatment of non–small cell lung cancer, the debate over video-assisted thoracic surgery segmentectomy still remains. This study compared the clinical outcomes using the two procedures for stage I non–small cell lung cancer patients.    Methods  Retrospective review was conducted on patients who underwent video-assisted thoracic surgery segmentectomy or lobectomy for clinical stage I non–small cell lung cancer at Shanghai Chest Hospital between November 2009 and May 2012. Video-assisted thoracic surgery segmentectomy was performed on 36 patients and video-assisted thoracic surgery lobectomy on 138 patients. Comparisons between the 2 groups were performed in patient demographic and clinical characteristics, intraoperative parameters and oncology outcomes.    Results  Mean volume of chest tube drainage after operation was smaller for segmentectomy than for lobectomy (1021 ml vs. 1328 ml, P=0.036). Other parameters analysis including blood loss, operation time, chest tube duration and length of hospital stay favors the segmentectomy group numerically without significance. There was no significant difference in distributions in both intra and post operative complications. There was one peri-operative mortality from segmentectomy group and all other patients are alive with a median follow up of 327 days. There were 1 (2.8%) locoregional recurrence after segmentectomy and 6 recurrences (4.4%) after lobectomy (P=1.00). Multivariate survival analysis revealed no significant difference in recurrence-free survivals between the two groups. Two patients successfully underwent bilateral segmentectomies and are free of disease.    Conclusions  For patients with stage I non–small cell lung cancer, video-assisted thoracic surgery segmentectomy offers a safe and equally effective option and can be applied to complicated operation such as bilateral segmentectomy.
