Due to the paucity of reports evaluating stress induced by thoracoscopic surgery with minithoracotomy, we assessed this stress based on the inflammatory response to surgery. Differences in pre- and postoperative peripheral white blood cell (WBC) count, serum C-reactive protein (CRP), and serum interleukin-6 (IL-6) were evaluated, defined as dW, dCRP, and dIL-6. Thoracoscopic partial lung resection cases were divided into 2 groups by access route: Group A patients in which surgery was concluded via several small access ports. and Group B patients going surgery via small access ports plus minithoracotomy. We also compared dW in standard lobectomy with exploratory thoracotomy (thoracotomy without lobectomy) cases. No significant difference was seen in dW, dCRP, or dIL-6 between groups. dW in response to exploratory thoracotomy was lower than that in standard lobectomy (p = 0.06). Surgical stress induced by thoracoscopic partial lung resection does not increase significantly when minithoracotomy is added. Postoperative inflammatory response may, however, be influenced by the extent of surgical trauma.
