Lobectomy is the standard surgical procedure for lung cancer and is also indicated for benign or relatively large diseases, such as tuberculous tumors and inflammatory pseudotumors, which require lobectomy. Lobectomy is mainly applicable to peripheral lung cancer, confined to irreversible lesions in the lobes of the lungs. Under general anesthesia, an incision is made between the ribs to expose the lung tracts, and the diseased lobes are removed after inspection of the chest cavity, while drainage strips are placed to drain the air, fluid, and blood from the pleural cavity, and the chest cavity is closed with sutures to close the skin. The human body has five lobes in the chest cavity, the left side is the upper lobe of the left lung and the lower part of the left lung, the right side is the upper lobe of the right lung, the middle lobe of the right lung and the lower lobe of the right lung, any of the lobes may have tumor lesions, then lobectomy plus mediastinal lymph node dissection can be done to treat the disease. After lobectomy, adequate oxygenation is required to keep the airway open.
