Small incision, big use Introduction of television thoracoscopic surgery for lung surgery Television thoracoscopic surgery (VATS) is one of the surgical treatments for lung cancer. The first thoracoscopic lobectomy was performed on September 9, 1991, but the first reported cases were more numerous in 1992 40 cases of VATS were reported for the diagnosis and treatment of malignant tumors, including 3 VATS lobectomies. 1993Kirby, Walker, Landreneau and others reported VATS lobectomies one after another. 1994 McKenna VATS lobectomy with lymph node sampling for lung cancer. 1996 Complete VATS anatomic lobectomy. 1997 100 consecutive VATS lobectomies with simultaneous pegging of the hilar structures without propping up the ribs. 1997 Lobectomy with lymph node dissection for lung cancer with a mean number of 24 lymph nodes dissected with no difference compared to conventional open chest. 2006 Mckenna reported 1100 VATS lobectomies, the highest number of cases to date. gossot systematically described the method of complete VATS lobectomy lung resection followed by extension of the incision and removal. 2010 Bagan complete chest wall trocar operated VATS lobectomy with the lesion removed from the subcostal arch incision. Thoracoscopic-assisted small incision surgery: requires an adjuvant incision of 6 cm or more and bracing of the ribs; direct vision operation; relatively safe and feasible; for less skilled surgeons; easily complicated; biggest problem is rib bracing; no significant advantage of postoperative pain compared to conventional open chest; total thoracoscopic surgery: the current mainstream surgical approach; 2-3 chest wall trocar incisions of about 1 cm in diameter One 3-5 cm adjuvant incision; no rib support; for hilar dissection; removal of the specimen bag and the resected lung tissue in it; non-direct vision operation; monitor assisted; conventional instruments and endoscopy-specific instruments Advantages: low surgical risk; mild postoperative pain; short hospital stay; rapid functional recovery; facilitates adjuvant therapy; if the patient’s tumor can be surgically removed and there are no limitations in oncology and thoracic surgery principles, VAT is considered an option. is considered an option if the patient’s tumor can be surgically resected and there are no limitations in oncology and chest surgery principles. Lung cancer guidelines: clinically diagnosed stage I lung cancer; clinically diagnosed stage II lung cancer, hilar lymph nodes not fused into a mass and easily resected endoscopically; benign lesions: branched enlargement, giant pulmonary bullae; pulmonary metastases; mass <5cm. Currently, television thoracoscopic surgery (VATS) has been used in our department for the diagnosis and treatment of various lung diseases, and because of the small incision, television thoracoscopic surgery has many advantages such as mild postoperative pain, short hospital stay, and quick functional recovery. It has many advantages such as small incision, less postoperative pain, shorter hospital stay, faster recovery, etc., which has benefited many patients.
