Lung cancer is one of the highly prevalent diseases in China. With the development of society, people’s demand for lung cancer is getting higher and higher. People demand the least damage while treating the disease. And this has invariably increased the difficulty of surgery for surgeons. However, with the development of thoracoscopy, making surgical incisions smaller is no longer a dream. What are the advantages of doing surgery with thoracoscopy? Then let’s make a comparison Traditional open-heart surgery Thoracoscopic surgery Large incision 25-30 cm Incision 2-3 cm Need to cut the thoracic dorsal muscles No cut thoracic dorsal muscles Need to brace the ribs or cut the ribs No need to brace the ribs and cut the ribs Postoperative wound is more painful Postoperative wound pain is reduced Postoperative wound affects cardiopulmonary function Postoperative mostly does not affect cardiopulmonary function Postoperative pain medication dosage Postoperative pain medication dosage is less Slow recovery Recovery is fast Hospitalization Days of hospitalization 7-14 d Days of hospitalization 2-5 d Also reduces the psychological and physical pain caused by the surgery, making it easier for patients to accept the surgery. It is safer for patients of advanced age and with relatively poor cardiopulmonary function. Can any patient with lung cancer use thoracoscopy? Of course not. There are strict indications for thoracoscopy. We select the following patients: ①Preoperative stage I~II, some stage III patients. ② lesions <5cm, no obvious enlarged lymph nodes in the hilum and mediastinum; ③ distant metastases excluded by head MRI, whole body bone scan, abdominal ultrasound, etc.; ④ no pleural hypertrophy and extensive adhesions; ⑤ no contraindications to surgery for blood gas analysis, lung function and other important organs. Although there are many advantages of small incisions, we should not just pursue small incisions and increase the operation time and difficulty. Television thoracoscopic surgery is a new technology that is less invasive to the patient, but it is still necessary to choose the most favorable surgical approach according to the patient's own indications. With the continuous development of newer instruments and equipment, together with the mature techniques of physicians and the accumulation of clinical experience, the indications and development of TV thoracoscopic surgery will continue to increase in the future for the benefit of more patients.
