Description/Scope

Epiduroscopy, also known as epidural spinal endoscopy or epidural myeloscopy, is an endoscopic procedure in which the epidural space is explored for the purpose of diagnosing and treating spinal pain, specifically radicular pain. A steerable or controllable flexible endoscope is used to examine the epidural anatomic structures to find epidural adhesions, fibrosis and scars, and to provide precision directed therapy.

Position Statement

Investigational and Not Medically Necessary:

Epiduroscopy, also known as epidural spinal endoscopy or epidural myeloscopy, is considered investigational and not medically necessary.

Rationale

There is insufficient scientific evidence in the peer-reviewed medical literature to determine the safety and efficacy of epiduroscopy as a diagnostic procedure or as a technique to guide interventional therapy.

Dashfield and colleagues (2005) reported on a study randomizing 60 participants with sciatica to undergo steroid injection with or without epiduroscopy guidance. No significant differences in outcomes were identified between the two groups. Ruetten and colleagues (2003) used epiduroscopy to guide intervention in 93 participants with chronic back-leg pain syndrome. Intervention was performed when considered appropriate; therefore, this study does not permit analysis of the contribution of epiduroscopy to the overall treatment. In a review article, Gill and colleagues (2005) reported on visual impairment as a complication of epiduroscopy, considered a rare but significant complication of the procedure. Their review identified 12 cases reported in the literature where a bolus injection of fluid resulted in a sudden increase in cerebrospinal fluid pressure ultimately compressing the optic nerve.    

Background/Overview

Epiduroscopy also known as epidural spinal endoscopy or epidural myeloscopy, is an invasive procedure that involves the insertion of a miniature fiberoptic scope into the epidural space. This device was approved by the U.S. Food and Drug Administration (FDA) in 1996. Epiduroscopy allows direct visualization to examine the epidural space for pathology (e.g. adhesions) that would contribute to chronic low back pain or radiculopathy. Although the procedure is mainly used for the visualization of the epidural space, treatments such as mechanical or laser lysis of spinal adhesions or introduction of steroids to areas of inflamed tissues may also be performed. The claimed benefits of epiduroscopy are that it may be used both as a diagnostic as well as an intervention for low back pain.

Definitions

Endoscope: A highly flexible viewing instrument with capabilities of diagnostic and therapeutic functions through special channels. 

Endoscopy: The visual inspection of any cavity of the body by means of an endoscope.

Radiculopathy: Any disease of the spinal nerve roots and spinal nerves; radiculopathy is characterized by pain which seems to radiate from the spine to extend outward to cause symptoms away from the source of the spinal nerve root irritation; causes of radiculopathy include deformities of the discs between the building blocks of the spine (the vertebrae).
