Uniportal video-assisted thoracoscopic lobectomy: An alternative to conventional thoracoscopic lobectomy in lung cancer surgery?

OBJECTIVES Although the standard video-assisted thoracoscopic surgery (VATS) approach is generally performed through two to four incisions, uniportal VATS pulmonary resection has recently been reported to be a promising, less invasive alternative. To evaluate the adequacy of uniportal VATS lobectomy as an alternative to conventional VATS lobectomy in lung cancer, we analysed and compared the outcomes of uniportal and conventional VATS lobectomies. METHODS Retrospective observational data for patients who underwent VATS lobectomy at Samsung Medical Center between January 2013 and February 2014 due to a diagnosis of lung cancer were collected. Perioperative factors such as operative time, postoperative chest tube duration, postoperative hospital stay, complication rate, conversion rate, reoperation rate and mortality were compared between the uniportal and conventional VATS groups. RESULTS A total of 90 uniportal VATS lobectomies and 60 conventional VATS lobectomies were attempted. Fifty-eight (64.5%) cases were completed as uniportal VATS lobectomies, and 51 (85%) cases as conventional VATS lobectomies. There were 32 (35.5%) conversions of uniportal VATS lobectomy cases, including four conversions to three-port VATS, 18 to two-port VATS and 10 to open thoracotomy. No differences in postoperative complications, postoperative 30-day mortality or reoperation rate were noted between the two groups. There was no difference in operative time, number of removed lymph nodes, chest tube duration or length of postoperative hospital stay between the uniportal VATS group and conventional VATS group. CONCLUSIONS The similar perioperative results of uniportal VATS lobectomy compared with conventional VATS lobectomy suggest that uniportal VATS is a viable alternative approach to the conventional VATS approach in selected patients, especially in patients with early peripheral lung cancer with good anatomy and in good general condition.
