Lung cancer is the most common primary malignant tumor of the lung. In the past 50 years, the incidence and death rate of lung cancer have increased rapidly in countries around the world, especially in industrialized countries, and lung cancer has taken the first place among male patients who died of cancer. Lung cancer surgery technology has become one of the standards to measure the level of a thoracic surgery. At present, domestic and foreign thoracoscopic lobectomy has been widely carried out, and the technology is becoming more and more mature. With the accumulation of relevant experience and the expansion and standardization of resection indications, it has developed into a new standard minimally invasive thoracic surgical technique. In the United States, 50-60% of patients with clinical stage I and II lung cancer are treated with thoracoscopic lobectomy. In China, few hospitals have performed thoracoscopic lobectomy and are still in the initial stage. In the past 10 years, our thoracic surgery department has made certain achievements in thoracoscopic surgery. In the past 3 years, our thoracic surgery department has fully mastered the technique of thoracoscopic lobectomy through the exchange with DUKE University Hospital and University of Maryland Hospital. With the consent of the ethics committee of our hospital, Deputy Chief Physician Yu Lei of the Department of Thoracic Surgery has successfully performed thoracoscopic lobectomy for lung cancer in the middle lobe of the right lung and the upper lobe of the left lung under the guidance of Director Li Jianye and Deputy Chief Physician Ma Shan and with the help of colleagues from the Department of Respiratory Medicine. This has brought our Thoracic Surgery Department to a new level in lobectomy surgery. Many people have long doubted the effectiveness of thoracoscopic application in lobectomy. Most foreign data have concluded by comparing thoracoscopic lobectomy with ordinary open-heart surgery that there is no significant difference between the two in terms of cure rate, postoperative complications, cancer recurrence rate, metastasis rate, and survival rate. However, thoracoscopic lobectomy has less damage and faster patient recovery, especially in terms of lymph node dissection, the thoracoscopic field of view is clear and more conducive to the thoroughness of lymph node dissection. Previously, the impression of open lobectomy surgery was that the surgical incision was long, mostly above 20-30 cm; the injury was large, and patients often needed 2-3 months to return to normal walking, but due to rib propping and rib fracture during open lobectomy, patients had long-term postoperative chest pain, and some patients took oral analgesic drugs for a long time. The thoracoscopic lobectomy incision is one approximately 1.5 cm lumpectomy incision and one approximately 3.5-4.5 cm long operating incision. No intraoperative rib spreading is required, postoperative pain is mild, chest tube placement time and hospital stay are significantly shorter, and most patients are out of bed by the second postoperative day. In the United States, thoracoscopic lobectomy patients can be discharged home to recuperate 2-3 days after surgery. The patient with lung cancer who underwent thoracoscopic left upper lung lobectomy performed in our thoracic surgery department was an elderly male with a tumor approximately 4*3*3cm3 in size and lacked a preoperative pathological diagnosis. Thoracoscopic observation of the tumor in the apical anterior segment of the left upper lung lobe and pleural wrinkling on its surface led to the decision to perform thoracoscopic resection of the left upper lung lobe and mediastinal lymph node dissection. This complex operation was completed with only one 1.5 cm long and one approximately 4 cm long surgical incision. He returned to the chest ward after only 18 hours of postoperative monitoring in the ICU and was out of bed. He returned to the thoracic ward without any analgesic medication. The thoracoscopic lobectomy surgery has enabled our thoracic surgery department to break through the stagnant situation in lung cancer surgery in recent years, and truly approach the domestic and even international advanced ranks in lung cancer surgery, which is of great significance to improve the thoracoscopic surgery technology. We believe that through the continuous efforts of the medical and nursing staff of thoracic surgery, the Department of Thoracic Surgery will achieve even greater success in the future.
