Facts About This Surgery
This very minimally invasive procedure combines the transpedicular approach to thoracic discs with the technology of endoscopic surgery. Using the transpedicular approach provides the surgeon an alternative to the extensive posterolateral approach, and to the thoracotomy approach which is open chest surgery. Utilizing an endoscope, which improves visualization much like the periscope of a submarine or the rear-view-mirror on an automobile does, further enhances the transpedicular approach in accomplishing the goal of successful disc resection. This provides the patient with a better chance of having the symptoms of pain or leg weakness resolved. The use of an endoscope and a less invasive surgical approach also leads to decreased postoperative complications. This surgery is usually done on an overnight basis.
