The Clinical Value Study Of Application Of Video-assisted Thoracoscopic Surgery In The Thoracic-cardiac Surgery

Since late 1930s,The integrate theoretical system and standard operative procedures have been formed. After 70-year development, great progress has been made in our nation in cardiothoracic surgery. But these standard operative procedures disturb normal physiology, impose great trauma, depress immune system severely and induce many complications or high risk factors. Patients, especially elderly, who cannot bear these impacts could lose the therapeutic option of surgery. Therapies for some illness, eg pneumothorax, which need to be performed more than onetime, or with simple intrathoracic procedure would be denied by patients with concerns about postoperative large scar that influencing cosmetic. Being part of multimodality therapy for advanced thoracic malignancy, palliative operation of reduced symptom and reduced tumor toxin with thoracotomy would facilitate tumor cells migration and disease progressing and the impair of autoimmune anti-tumor mechanisms.Along with living improvement and life elongation, new requirements have been brought up to us in diagnostic and therapeutic works. That is "how to achieve timely, definitive diagnosis and safe, effective treatment with least physical and psychological injury, lowest risk and favorable postoperative cosmetic appearance", which theoretically compose a novel academic concept "mini-invasive thoracocardiac surgery".Stepping into 1990s, explosive developments in electrics and high accurate optics techniques made the "video-assisted thoracoscopic system" into reality. Meanwhile invention of the specialized instruments for high-tech thoracoscopic tunnel surgery and involvement of thoracocardiac surgeons compose a set of novel mini-invasive thoracosopic surgery, known as "video-assisted thoracoscopic surgery, VATS".In 1992, Lewis and Landreneau were the first persons who succeeded in treating thoracocardiac diseases with VATS. In the following years, many scholars worked in clinical practice and theoretical research and made the conclusions. Most of them take for it as mini-invasive, less blood-losing, less painful and quick recovering. During...
