New Approach to Complete Video-assisted Thoracoscopic Lobectomy in T2 and T3 Non-Small Cell Lung Cancer

Complete video-assisted thoracoscopic surgery (c-VATS) for lung cancer is minimally invasive because of the small incision required. c-VATS has recently become a standard procedure for treatment of stage IA/IB lung cancer. However, a long thoracic incision or extensive costal rib resection is required in patients with large lung tumors. We herein introduce an improved VATS lobectomy procedure for patients with T2 and T3 lung cancer. In this technique, resected tissue is removed through a small upper abdominal midline incision below the xiphoid through the retrosternal-extraperitoneal pathway. Five patients who underwent this new procedure were compared against 10 control patients who underwent hybrid VATS lobectomy. Significantly fewer patients who underwent c-VATS lobectomy complained of severe postoperative pain; however, there was no significant difference in the postoperative hospital stay between the two groups. The present study demonstrates that c-VATS lobectomy can be performed with minimal operative pain and without need for a long thoracic incision or extensive rib resection, even in patients with large lung tumors (T2 and T3). These results suggest that the indications for c-VATS lobectomy in patients with T2 and T3 non-small cell lung cancer can be expanded by implementation of our approach, which involves removal of the freed lobe through an abdominal incision.
