Surgical resection is the main method of treating malignant tumors and some benign lesions in the lung. With the improvement of lumpectomy equipment and surgical techniques, complete lumpectomy has been partially replacing traditional open-heart surgery with the advantages of safety, smaller effective incision, and less disturbance to patient physiology; this surgical method also has the advantages of less postoperative pain, shorter hospital stay, faster return to work, fewer pulmonary complications and less loss of lung function, and more importantly for lung cancer patients, it does not affect Survival. Nevertheless, although there is no uniform standard for the use of lumpectomy instruments to complete total lumpectomy for traditional thoracoscopic lung resection surgical techniques, most surgeons need to choose more than 2 incisions to complete thoracoscopic lobectomy, i.e., 1 observation hole (for lumpectomy placement, 1.5 cm) and 1-3 operating holes of varying sizes (for placement of thoracoscopic operating instruments, the largest being less than 5 cm). incision is less than 5 cm). The true meaning of single-port thoracoscopic lobectomy is that all surgical operations in the thoracic surgical field are done under a single incision, i.e., a 5 cm incision that accommodates the lumpectomy with illumination and surgeon’s view, and at least two lumpectomy instruments; it is indeed “single-port”! Scientific studies have confirmed that there is no significant difference in length of stay or complication rates between the two groups for lung cancer patients undergoing single-port thoracoscopic pneumonectomy. Compared to multiport thoracoscopy, single-port thoracoscopic lobectomy and segmental lung resection have shorter hospital stays, more lymph nodes removed and less intraoperative bleeding, with perioperative outcomes comparable to those of multiport thoracoscopy.
