Whether or not minimally invasive surgery to remove a pulmonary nodule has any effect later on is primarily related to the patient’s underlying lung function in a significant way. If a pulmonary nodule occurs in a healthy adult, the effect on the patient after minimally invasive surgery is very small. In case of long-term smoking, with bronchial asthma, chronic obstructive pulmonary disease, old tuberculosis, pulmonary fibrosis, bronchiectasis, etc., the patient’s own basal lung function is relatively poor, and the patient’s lung function is easily affected after surgery, with heart tiredness and shortness of breath after activity. It is more likely to cough, cough sputum, blood in sputum and even fever if accompanied by infection, so minimally invasive surgery to remove pulmonary nodules has less impact. Unless the patient is older, has more underlying diseases, and has poor lung function. In particular, long-term smoking and people who work with dust, such as masons, coal mines, hairdressers and chefs, are likely to lead to poorer recovery of lung function and recurrent infections after surgery, resulting in a prolonged course of the disease and affecting the prognosis of pulmonary nodules.
