Lung nodule surgery, even though minimally invasive surgery is now used, is still a major operation in the strictest sense of the word, requiring a thorough preoperative evaluation of the patient to ensure that the patient can both have the lesion removed and be safely discharged from the hospital. Therefore, after evaluating the patient’s physical condition and determining the ability to operate, the lesion is removed through thoracoscopic surgery techniques under general anesthesia and sent to the pathology department for laboratory testing. If the test is malignant, the most popular method worldwide is radical lung cancer surgery with lymph node dissection, in which the corresponding lobe or segment is removed and the surrounding lymph nodes are dissected. If the nodule is benign, only the lesion needs to be removed. Nowadays, patients are instructed to move on the ground on the first day after surgery and are allowed to eat on the first day, so generally, they can be discharged from the hospital in 4-7 days after surgery and the sutures are removed in 7-10 days after surgery.
