The best treatment for pneumothorax without recurrence is surgery. There are many ways to treat pneumothorax. If there is a small amount of pneumothorax, it can be absorbed on its own and does not require any special treatment; if there is a lot of gas, closed drainage of the chest cavity is feasible or surgical treatment can be performed. If there are indications for surgery, surgical treatment, such as thoracoscopic resection of diseased lung tissue, can remove the diseased lung tissue, thus preventing the reoccurrence of pneumothorax. If non-surgical treatment is chosen, since the diseased lung tissue still exists, the pneumothorax may reoccur, so the best treatment for non-recurrence of pneumothorax is surgery. After the diagnosis of pneumothorax is confirmed, a comprehensive examination is needed to evaluate the patient’s physical condition, and the severity of the disease needs to be judged before choosing the appropriate treatment.
