With the continuous development and maturation of TV thoracoscopic technology, minimally invasive surgery for lung cancer has made great progress in the past 20 years. At present, TV thoracoscopic surgery is the main procedure of minimally invasive surgery for early-stage lung cancer. The results of multicenter studies at home and abroad show that TV thoracoscopic surgery for early-stage lung cancer can achieve the same effect as traditional open-heart surgery. What kinds of minimally invasive treatment for lung cancer are there? Minimally invasive surgical techniques for lung cancer mainly include two categories: small incision surgery with preservation of chest wall muscles and thoracoscopic surgery. Lung cancer surgery that preserves the chest wall muscles can improve the early postoperative pain and reduce the occurrence of pulmonary complications and facilitate recovery. The more frequently used surgical pathways are mainly the small axillary incision and the auditory triangle incision. 2, and TV thoracoscopic minimally invasive surgery can be divided into 3 surgical approaches, namely complete thoracoscopic lobectomy, thoracoscopic-assisted lobectomy and thoracoscopic-assisted small-incision lobectomy. A study by foreign scholars found that for peripheral type lung cancer <3 cm undergoing televised thoracoscopic lobectomy, the results showed that the success rate, morbidity and mortality rate, recurrence and survival of the operation were not significantly different from those of conventional open-heart surgery, and the operation time was slightly longer than that of open-heart surgery, and no significant differences were seen in postoperative complications and 1-year survival. Similar results have been obtained in domestic studies. Based on the results of recent studies, most experts agree that thoracoscopic lobectomy combined with lymph node dissection is consistent with the principles of oncology treatment and has been recognized by authoritative institutions such as the nccn guidelines for the treatment of non-small cell lung cancer. Since the most recognized total thoracoscopic lobectomy is suitable for early stage lung cancer with relatively small tumors, it is the least traumatic for patients, with rapid postoperative recovery and short hospital stay. Its minimally invasive value is of even greater relevance if surgical resection smaller than the anatomical extent of the lung lobes can be performed in these patients to preserve maximum organ function.
