Status: Reviewed | Last Review Date: 11/09/2023 |
Description/Scope |
This document addresses epiduroscopy, also known as epidural spinal endoscopy or epidural myeloscopy, an endoscopic procedure where the epidural space is explored for the diagnosis and treatment of radicular spinal pain.
Note: Mechanical or laser lysis, which may be performed with epiduroscopy, is addressed in a related document. Please see the following for additional information:
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 peer-reviewed medical literature to determine the safety and efficacy of epiduroscopy as a diagnostic procedure or as a technique to guide interventional therapy.
Bosscher and Heavner (2012) published a study evaluating epiduroscopy used as a diagnostic procedure. The investigators used spinal canal endoscopy to study the spinal segment(s) where pain was elicited via endoscopic evaluation vs. the vertebral level from where the pain was thought to originate, as determined by clinical evaluation and by MRI. A total of 143 individuals who underwent spinal canal endoscopy (epiduroscopy) were asked whether pain generated by pressure upon epidural structures with the tip of an endoscope was similar in character and distribution (concordant) to the pain for which the individuals sought treatment. codingThe most common level was at L4 to L5. The least common level was L5 to S1. In 40 participants, the level determined by clinical evaluation correlated with the level at which pain could be reproduced during epiduroscopy. In 28 participants, the MRI indicated a specific vertebral level that corresponded to the level at which pain could be reproduced with epiduroscopy. The authors concluded that epiduroscopy is more reliable than is either clinical evaluation or MRI for determining the vertebral level where clinically significant spinal pathology occurs. However, this study was small, not randomized or blinded and had the potential for bias.
Dashfield and colleagues (2005) published the results of a randomized controlled trial (RCT) evaluating epiduroscopy to guide interventional therapy for 60 participants with sciatica undergoing steroid injection treatment. No significant differences in outcomes were identified between the group that received epiduroscopy guidance and the group that did not.
There are published case series evaluating epiduroscopy for guiding intervention (Hazer, 2018; Ruetten, 2003). In 2018, Hazer and colleagues retrospectively reviewed 88 individuals with low back pain and radicular pain who received epiduroscopy. Compared with baseline, after epiduroscopy, there were significant decreases in pain as measured by a visual analogue scale (VAS) and the Oswestry Disability Index (ODI), p<0.001 for each. The study was limited by the lack of a control or comparison group.
Gill and colleagues (2005) reported on 12 cases of visual impairment as a complication of epiduroscopy, considered a rare but significant complication of the procedure, in which a bolus injection of fluid resulted in a sudden increase in cerebrospinal fluid pressure and compression of the optic nerve.
Background/Overview |
Epiduroscopy, also known as epidural spinal endoscopy or epidural myeloscopy, is a procedure in which a steerable or controllable flexible endoscope is used to visually examine the epidural anatomic structures. The procedure is mainly used for the visualization of the epidural space to identify epidural adhesions, fibrosis, and scars. In addition, epiduroscopy can be used for visualization during interventions such as mechanical or laser lysis of spinal adhesions, or introduction of steroids to areas of inflamed tissues. The Myelotec Myeloscope (Myelotec, Inc. Roswell, GA) device was cleared by the U.S. Food and Drug Administration (FDA) in September 1996.
Definitions |
Endoscope: A highly flexible fiberoptic instrument which allows the user to see the inside of the body for diagnostic procedures and allows for therapeutic functions through special channels built into the scope that allow passage of specialized tools to the treatment area.
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).
