Thoracoscopy for peripheral lung cancer near pleura is difficult, and part of the trachea has to be removed during surgery. If the tumor is close to the pleura, it belongs to peripheral lung cancer, and there are no important tissues around the tumor, such as large blood vessels and main bronchial tubes, etc. Part of the trachea or blood vessels need to be resected during the surgery, and tracheal sleeve anastomosis and artificial vascular anastomosis should be done. Confirmed diagnosis of peripheral lung cancer requires surgical treatment as soon as possible. Thoracoscopic surgery is usually used to remove lung cancer in clinical practice, which is less traumatic to the body and basically does not need to open the chest. It is best to perform lobectomy if the patient is in good health and can tolerate it. Surgery for peripheral lung cancer is performed in the same way as for other types of lung cancer, with maximum removal of tumor tissue followed by maximum preservation of normal lung tissue. Complete removal of the tumor is radical treatment, but it does not mean cure. Because of some early tumors, tumor detachment or micrometastasis has already occurred before surgery, and even exists outside the scope of radical treatment. At this time, comprehensive treatment should be adopted after radical treatment, including chemotherapy and radiotherapy to further consolidate the therapeutic effect. If peripheral lung cancer is diagnosed, one should seek medical treatment in time and treat it as early as possible to avoid delay.
