[Thoracoscopic subsegmental and segmental resection for postoperative local recurrence of lung cancer based on the...

After lung cancer surgery, because chest computed tomography (CT) examinations are conducted frequently, recurrent cancer is often discovered at an early stage. In postoperative cases, because the lung volume has already decreased, radical limited surgery is therefore required. Before performing lung resection, we create a three-dimensional image of the lung, using CTTRY, on a personal computer and conduct a simulation of the resection range before moving on to surgery and accurately and smoothly performing thoracoscopic segmental and subsegmental resection. In the past 2 years, we have treated 5 cases of ipsilateral cancer and surgery for recurrence using this surgical technique. This case was a 66-year-old female. Right lower lobectomy was performed to treat primary squamous cell carcinoma of the lung. Recurrence was observed in CT examinations during the follow-up, and right S2 segmentectomy was performed. For performing radical limited surgery for recurrent lung cancer, avoiding completion pneumonectomy, it is therefore very useful to review the surgical procedures using CTTRY.
