Advantages of thoracoscopic lobectomy 1. Significant reduction of postoperative pain: One of the advantages of thoracoscopic surgery is that it reduces the postoperative pain of patients, reduces the application of postoperative analgesic drugs to patients and reduces the occurrence of postoperative pulmonary atelectasis. Postoperative pain in thoracic surgery is mainly related to rib propping, so thoracoscopic lobectomy without rib propping is more in line with minimally invasive surgery; the surgical incisions are two incisions of approximately 1.5 cm and one incision of approximately 3.5-4.5 cm in length at the anterior axillary line of the 4th intercostal space. (while the incision of conventional open-chest surgery is about 20cm long) 2.shorten the hospital stay; 3.comparison of lung function and mobility: thoracoscopic surgery, because the chest wall muscles are not cut off and the ribs are not propped open, preserves the integrity of the thorax and the patient’s respiratory function to a large extent compared with conventional open-chest surgery. Some patients can get out of bed the day after surgery. 4.Reducing the decrease of immune function: Surgery will reduce the immune function of the body to different degrees, and the greater the surgical trauma, the greater the impact on the immune function, especially the immune function of tumor patients is related to the recurrence and metastasis of tumor. Lymph node dissection in thoracoscopic surgery There is a big controversy on the issue of mediastinal lymph node dissection in thoracoscopic lung cancer surgery, based on our clinical practice experience, we believe that technically it is safe and feasible to perform lymph node dissection thoracoscopically. Lymph nodes. There is no difference in the number of groups and number of lymph nodes with conventional open-chest lymph node dissection. However, in individual patients, the lymph nodes are enlarged and fused into clusters, and the relationship with blood vessels is dense, which makes full lumpectomy difficult, and these patients need to extend the incision appropriately and perform small incisions under the auxiliary lobectomy. Therefore, lumpectomy lymph node dissection is safe and feasible. Cost issues Since only disposable instruments under lumpectomy can be used to sever large blood vessels and bronchi under thoracoscopy, the cost is about 10,000 yuan higher than that of traditional open-heart surgery.
