Today, the treatment of postoperative pain after lung resection is based on association of the pharmacological therapy, including systemic use of opioids and non-steroid drugs, epidural analgesia, intercostal nerve block and cryoanalgesia with the minimally invasive surgery, like use of mini-thoracotomy, a thoracoscopic approach or intercostal nerve protection with the use of muscle sparing. In the literature, reduced tissue damage consequent to the use of limited surgical approaches is reported to be significantly effective in decreasing early postoperative pain. Thus, the use of a minimally invasive surgery for lung resections has proved to produce more tolerable pain and allow quicker functional recovery and lower postoperative complications. The aim of this prospective randomized study was to evaluate the equivalency of a smaller incision (4 cm) when compared to a longer length (8 cm) of incision performing uniportal VATS lobectomy in terms of postoperative pain results. Primarily, to evaluate the differences of operative time between the groups.
