Minimally invasive surgery for lung cancer is very effective, and its advantages are reflected in the following aspects: I. Performing minimally invasive surgery requires less basic lung function of the patient than thoracotomy. Second, minimally invasive surgery has a better field of vision than traditional open thoracotomy because of the magnifying effect of the luminal microscope. Third, less traumatic, traditional open-heart surgery is generally incised at least 20-30cm, thoracoscopic surgery incision is generally 1-3cm, and intraoperative contact with the organs is less, the overall immune function of the patient is less impact, which makes the patient’s perioperative pain is reduced, reduces the application of postoperative analgesic drugs, as well as the occurrence of intractable intercostal neuralgia. Patients generally recover faster, traditional open heart surgery usually takes 10-14 days to be able to leave the hospital, while most minimally invasive surgery patients can be discharged in 3-7 days. Fourth, minimally invasive surgery also meets the requirements of cosmetic surgery, because the scar is smaller, reducing the psychological burden of patients after surgery. Many clinical researches show that there is no obvious difference between thoracoscopic lung cancer surgery and traditional open-heart surgery in terms of thoroughness of surgery, lymph node clearance and long-term survival rate, while it is obviously better than traditional open-heart surgery in terms of operation time, intra-operative bleeding, post-operative pain and hospitalization time.
