The next step in the management of pulmonary blisters and pulmonary nodules depends on the number, size and shape of the nodules. If the pulmonary nodule is a single pulmonary nodule without any clinical symptoms, we only need to review it regularly. If the patient has a large pulmonary blister, recurrent infections and pneumothorax, and the blister is relatively limited, we may consider surgery. If the pulmonary blister is scattered with two lungs and the lung function decreases significantly, we can take a comprehensive treatment such as anti-infection, expectoration and pneumothorax. If the pulmonary nodule is a single nodule with smooth margins, we consider it to be a benign nodule that requires only periodic review. If the nodule is large, with unsmooth margins and burr signs, we consider it to be a malignant nodule, which requires further improvement of bronchoscopy, nodule puncture biopsy and other related examinations, and we can consider surgery, radiotherapy, chemotherapy or targeted cell drug therapy after the diagnosis of malignant nodules.
