Lung lobectomy is performed for localized irreversible and relatively severe lesions of the lung tissue, including severe infections, localized necrosis of the lungs, and malignant tumor-occupying lesions, and can be performed under general anesthesia. First, an incision is made between the ribs at the site of the corresponding projection of the lesion to fully expose the desired part of the lung. After examining the chest cavity, the diseased lobe is resected and drainage strips are placed to drain secretions, fluid, blood, and air from the pleural cavity. The chest cavity is also closed and the skin tissue is sutured. The drains may be left in place for 2-3 days, depending on the case, and the status of the drainage fluid is monitored at all times, with follow-up visits to prevent infection. Antibiotics such as amoxicillin and penicillin can be used for 3 days postoperatively to follow up at any time.
