Endoscopic discectomy is a minimally invasive procedure performed to treat pressure on nerve roots caused by herniated discs. It is performed using a tubular device that relieves the pain caused by herniated discs. Under general anesthesia, the surgeon inserts a small metal tube into the spine with the purpose of direct visualization. Through this tube, surgical tools are cut, eliminating the need to tear or cut the patient’s muscles. The annular tear, bulging or herniated disc is found by looking through the tube and removed.
