Lung cancer is a relatively common malignant tumor that increasingly endangers human physical and mental health. The comprehensive treatment method with surgical treatment as the core is the basic treatment principle of lung cancer treatment nowadays. The surgical methods for lung cancer treatment are divided into minimally invasive surgery and traditional open-heart surgery. Which surgical method is more advantageous, open-heart surgery or minimally invasive surgery? The development trend of modern medicine has made it clear that minimally invasive surgery is the general trend and expected by all. I. What is traditional open-heart surgery? The surgical instruments used in traditional open-heart surgery for lung cancer are large, thick and long, and the incision is located on the lateral chest wall, almost half of the chest wall, and the incision often exceeds 25 cm, which is long and traumatic. The operation is performed by hand; only the surgeon has the best view, and the tumor is removed under direct vision. Postoperative pain is obvious and painful, and patients’ upper limb function may be affected by it to a greater or lesser extent after surgery. The patient’s recovery is also slow, and the “centipede” scar of more than 25 cm after open-heart surgery is also a strong psychological blow to the patient. Second, what is minimally invasive surgery method? The emergence of minimally invasive thoracoscopic surgery has brought a vibrant spring to thoracic surgery. Minimally invasive thoracoscopic surgery is to make several small holes of about 1.5cm in length in the chest, and send the camera lens and miniature surgical instruments into the chest through the small holes respectively, so that the location of the lesion can be easily found under the TV screen. Compared with traditional open-chest surgery, minimally invasive has a broader surgical field of view although the opening is small: through the flexible camera lens, one can clearly see the places that are not easily and inconveniently observed in traditional open-chest surgery, and then perform surgery on the lesion site through microsurgical instruments to completely remove all the diseased tissues and achieve the purpose of radical surgery. The surgical instruments are small, thin and long, so the surgery is less traumatic to the patients, the pain of the patients is reduced, the post-operative recovery is fast and the hospitalization time is greatly shortened. Can minimally invasive surgery cut the tumor cleanly? Does minimally invasive thoracoscopic surgery have the same surgical effect as traditional open-heart surgery? Can the thoracoscope see clearly during the surgery? Can the mass be cut cleanly? The answer is yes! Yes! Minimally invasive thoracoscopic surgery can achieve the same results as traditional open-heart surgery, or even better! Thoracoscopic surgery is much clearer than traditional open-heart surgery! The masses are removed as cleanly as in traditional surgery! Because thoracoscopy greatly increases the “vision”, “field of view” and “line of sight” of the surgeon (main surgeon and assistant), thoracoscopy can reach the surgical site that cannot be seen directly or not easily by traditional open surgery. With the magnification of the thoracoscope, the lesion can be clearly displayed on the screen, so the operation will be more accurate and the quality of the operation will be higher, so that the operation can be seen clearly and the mass can be cut cleanly. These have been recognized at home and abroad. What has thoracoscopic surgery changed in the treatment of lung cancer? Minimally invasive thoracoscopic surgery has brought six major changes to lung cancer treatment: 1) Changed the attitude of patients and lung cancer colleagues towards lung cancer surgery 2) Changed the understanding of lung cancer 3) Changed the concept of lung cancer treatment 4) Changed the timing of lung cancer surgical intervention: shifting the treatment forward 5) Changed the quality of life and survival value of patients 6) Changed the overall treatment effect of lung cancer With the widespread application of new theories, techniques and instruments in minimally invasive surgery, thoracoscopic minimally invasive surgery has replaced traditional open-heart surgery and become the main surgical treatment for lung cancer. Minimally invasive surgery accounts for more than 68% of all our surgeries, and minimally invasive surgery covers all thoracic surgeries, among which minimally invasive lung cancer surgery has long been the most routine minimally invasive surgery performed by our team. The immediate and long-term results are as good as or better than those of traditional open-heart surgery. In addition, our team is able to perform a variety of difficult minimally invasive surgeries, such as lobectomy, total pneumonectomy, vascular bronchoplasty, etc., which are at the top level in China and the leading level in the world.
