Introduction: Video-assisted thoracic surgery (VATS) is now commonly used for primary spontaneous pneumothorax. In the present study we compared the outcomes of this technique with those obtained by conventional thoracotomy.Material and Methods: In this cross-sectional stud, forty patients were enrolled into two groups: VATS (n=20) and thoracotomy (n=20). In both groups the blebs were resected ...
