[A clinical evaluation of the practical reliability in video-assisted thoracic surgery for right primary lung cancer].

Recently, lobectomy by video-assisted thoracic surgery (VATS lobectomy: VL) has been widely applied to peripheral lung cancer because of its less invasive approach compared to standard thoracotomy (ST). However, the appropriate approach in VL still remains to be solved. The aim of this study was to evaluate the practical reliability of our technical devices in VL for right primary lung cancer. For the VATS procedures, a mini-thoracotomy measuring about 6-7 cm was made in the fourth or fifth intercostal space (ICS) under the auscultatory triangle without rib resection. Two access holes 12 mm in size were also made in the fourth ICS at the anterior axillary line and in the seventh ICS at the posterior axillary line, respectively. These access holes were used for insertion of thoracoscope, endoscopic stapler or retracting instrument according to operative procedure. After stapling of the vessels and bronchus, the resected pulmonary lobe was removed from the thorax using a plastic retrieval bag. The present study showed the technical feasibility of this unique thoracoscopic approach in the standard lobectomy with systematic nodal dissection for right lung cancer.
