The incidence of esophageal cancer is high in our city, and surgery is the best way to treat esophageal cancer. For a long time, the traditional surgery for esophageal cancer is “open chest”. Opening the chest means incision of more than ten centimeters or even tens of centimeters, which is very traumatic. In the early years, traditional surgery also required cutting off ribs or even removing one rib, and using rib spreader to spread ribs during the operation, which caused great damage to the patients, obvious postoperative pain, great suffering and slow recovery. In the chest to play a few small holes about 2cm long, with a camera lens of the optical fiber and micro-surgical instruments were sent into the chest through the small holes, in the TV screen monitoring to find the location of the lesion, the lesion parts of the implementation of the operation, complete removal of cancerous masses and systematic clearance of all the enlarged lymph nodes, to achieve the purpose of radical surgery, and the wounds only need to be sutured with absorbable sutures or stick on the dressing can be! –This is a brand-new thoracic surgery method–thoracoscopic minimally invasive treatment technique. Thoracoscopic surgery is considered to be the biggest technological revolution in the field of thoracic surgery. With the development of thoracoscopic surgery, esophageal cancer has ushered in the “minimally invasive era”. Thoracoscopic surgery not only has the advantages of small trauma, light pain, fast recovery and beautiful incision, but also has the advantages of TV screen display during operation, which has the effect of magnification, and increases the “vision”, “field of view” and “line of sight” of the operator, thus enlarging the “vision” of the operator. It also increases the “vision”, “field of view” and “line of sight” of the surgeon, enlarges the scope of surgery and facilitates intraoperative cooperation. Minimally invasive surgery for esophageal cancer completes the resection of esophageal cancer tumor under thoracoscopy, which transforms the traditional open chest incision of more than 25cm across half of the chest wall into 3-4 small holes of about 2cm in length, with less trauma and less bleeding. Postoperative pain is significantly reduced, patients can get out of bed at an early stage, recover quickly, realize early feeding, and the postoperative surgical scars are small, with little impact on the appearance, no longer the long and large “centipede” scars after the previous open-heart surgery, and the quality of life of patients is significantly improved after the operation. The quality of life of the patients after the surgery is significantly improved. The curative effect is the same as or even better than that of traditional open heart surgery. Thoracoscopic minimally invasive surgery plays an increasingly important role in the treatment of esophageal cancer. Thoracoscopic minimally invasive esophageal cancer surgery requires surgeons to operate with high technical requirements, and compared with traditional open heart surgery, it requires higher precision, stability, patience and carefulness.
