As management of spinal pain is shifting to non-surgical techniques, spinal endoscopy has become widely used for patients with low back pain and/or leg pain. The additional use of lasers has extended the skills and indications of epiduroscopy, and has been named epiduroscopic laser neural decompression (ELND). Studies in ELND show good results for low back pain and/or leg pain with herniated discs, spinal stenosis, failed back surgery syndrome, etc. [45] The process of ELND gave us the information about the epidural space, as well as a therapeutic tools such as prolapsed disc removal, adhesiolysis in the epidural space, and the direct drug administration at the pathologic site in the epidural space. However, most of pain doctors are focusing on the therapeutic aspect, when they try to perform epiduroscopic procedures.

A comparison of epiduroscopy and MRI shows us that epiduroscopy is a better tool for diagnosing the vertebral level of low back and/or leg pain patients [6]. History taking and physical examination are essential to diagnosis. The first step of physical examination is inspection, to see. The original purpose of various scopes is to observe. Epiduroscopy is a tool for watching the epidural space using an endoscope through the caudal approach. We can watch the epiduralspace from the sacral hiatus to whichever level we want to see in the anterior and posterior epidural space.

In the future, epiduroscopy could be one of the essential steps for diagnosing low back pain and/or leg pain. Furthermore, more sophisticated education and qualified certification will be needed for performing epiduroscopy. ELND is an additional benefit of performing a therapeutic management during diagnostic epiduroscopy.
