Pneumothorax has less sequelae after thoracotomy. In order to prevent the recurrence of pneumothorax, it is necessary to cauterize, ligate or suture complex pulmonary bullae at the pleural leakage site to close the leakage. The recurrence rate of pneumothorax after thoracotomy is very low. The failure rate of pulmonary bullae ligation/resection, thoracopleural fixation and pleurectomy at the tip of lung or whole lung wall were all below 0.5%. The comprehensive incidence of complications of thoracotomy in patients with pneumothorax was 3.7%, mainly sputum retention and postoperative infection. Generally speaking, open chest surgery adopts unilateral lung ventilation, and lateral incision surgery adopts visceral pleurectomy, pneumonectomy, pulmonary bullae ligation or pleurodesis. Compared with thoracotomy, thoracoscopic surgery is to make three incisions about two centimeters in the chest, armpit and back, with little trauma. The whole recovery period is similar to thoracotomy. In order to reduce trauma, patients can consider thoracoscopic surgery. There may be discomfort in the surgical site about three months after operation, and it will basically return to normal after half a year. Pneumothorax patients need to rest after thoracotomy to avoid catching a cold and actively use antibiotics to prevent infection. Keep a relaxed attitude, pay attention to smoking less, strengthen nutrition during this period after operation, and try not to do anything that will make the lungs expand sharply. After all, the wound may not heal completely, but it will be fine in a few months. The above content is an introduction to whether there will be sequelae after pneumothorax thoracotomy. I believe that after reading it, you will have a certain understanding of whether there will be sequelae after pneumothorax thoracotomy. I hope I can help you.
