Comparison of minimally invasive thoracoscopy versus open thoracotomy for staging lung cancer

Minimally invasive thoracoscopic staging for lung cancer was compared with re-staging by open thoracotomy in seventeen patients to evaluate whether videoimaged thoracoscopic staging was accurate. Seventeen patients underwent thoracoscopic staging initially with a closed videoimaged technique. These same patients then underwent an open thoracotomy and re-staging with a therapeutic resection for lung cancer. All patients underwent pleural evaluation and biopsy if indicated, thoracic hilar and mediastinal lymph node sampling, and then resection of the parenchymal lesion via a wedge resection, lobectomy or pneumonectomy. There was complete TMN stage correlation between the closed videoimaged thoracoscopic and open thoracotomy techniques. This preliminary study suggests minimally invasive videoimaged thoracoscopic staging is an accurate method to assess the stage of lung cancer to guide rational management.
