Video-assisted thoracoscopy is increasing in popularity. Although it is considered a less invasive treatment than thoracotomy, patients have reported moderate to severe pain of variable duration. Benefits of adequate analgesia no longer need to be demonstrated. Optimal analgesia leads to faster recovery, reduces the risk of postoperative complications, enhances patient's satisfaction and quality of life following surgery. Furthermore, adequate postoperative analgesia may reduce the occurrence of chronic pain. The incidence of chronic pain following thoracoscopic procedures ranges from 20-47%.
