Epiduroscopy is a minimally invasive procedure that allows exploration of the epidural space of the spine using a thin flexible endoscope.
The epidural space is the area located inside the spinal canal, outside the dura mater, the membrane that surrounds the nerve roots and spinal cord.
This technique is used for both diagnostic and therapeutic purposes, particularly in patients with persistent low back and radicular pain, often resulting from scar tissue adhesions, chronic inflammation or the outcomes of previous spinal surgery.
Indications
Epiduroscopy may be indicated in patients with chronic low back pain, lumbosciatica or persistent radicular pain despite conservative therapies, injections or minimally invasive treatments.
One of the most frequent indications is the so-called failed back surgery syndrome, a condition in which the patient continues to experience pain after spinal surgery. In these cases, the pain may be related to the formation of scar tissue adhesions in the epidural space, which can irritate or compress the nerve roots.
The procedure can also be useful in cases of epidural fibrosis, spinal canal stenosis of varying degree that, for various reasons, is not suitable for surgery, chronic radiculopathy, persistent periradicular inflammation or neuropathic pain not adequately controlled by other treatments.
Goals of the procedure
Epiduroscopy is aimed at directly visualizing the epidural space and, when necessary, treating the abnormalities found. Through the endoscope, the physician can identify areas of inflammation, scar tissue adhesions, narrowing or areas where the nerve roots are irritated.
From a therapeutic standpoint, the procedure allows adhesiolysis to be performed, meaning the mechanical or pharmacological release of epidural scar tissue. This can reduce tension on the nerve roots and improve the distribution of anti-inflammatory or analgesic medication directly at the site of pain.
During epiduroscopy, targeted medications may be administered, such as local anesthetics, corticosteroids, saline solution or other specific preparations, near the affected nerve roots.
How the procedure is performed
The procedure is performed in a sterile environment, generally in an operating room or a room dedicated to interventional pain procedures. The patient is usually positioned prone, lying face down.
After thorough skin disinfection and local anesthesia, access to the epidural space is generally obtained through the sacral hiatus, a small anatomical opening located at the base of the sacrum. A needle or introducer is inserted through this access, through which the epiduroscope is then advanced.
The correct positioning of the instruments is verified with radiological guidance. The endoscope, equipped with fiber optics or a video system, allows the epidural structures to be observed and the treatment to be directed to the affected area.
The procedure has a variable duration, generally between 30 and 60 minutes, depending on the complexity of the case and the therapeutic goals.
Lysis of epidural adhesions
One of the most important aspects of epiduroscopy is the ability to treat epidural adhesions. Adhesions are scar tissue that can form after surgery, chronic inflammation or degenerative processes. When they involve the nerve roots, they can contribute to persistent pain.
Lysis can be performed with gentle mechanical maneuvers, using small dedicated instruments or through the targeted injection of solutions that help separate the scar tissue.
The goal is not to completely remove every scar, but to reduce the irritative or compressive effect on the nerve structures and improve the distribution of medication within the epidural space.
Advantages
Epiduroscopy allows direct visualization of the epidural space, providing information that is not always fully obtainable with imaging studies alone. This allows for more targeted treatment compared with traditional epidural injections.
The procedure is minimally invasive, does not require large surgical incisions and involves limited tissue trauma. It can be performed as day surgery or with brief post-procedural observation.
Another advantage is the ability to administer medication directly at the site of pain, especially in cases where the presence of adhesions prevents proper distribution of substances injected with standard techniques.
Limitations
Epiduroscopy is not indicated for all patients with low back or radicular pain. It does not replace surgery in cases of large disc herniation, severe stenosis with significant neurological compression, spinal instability or progressive neurological deficits.
The success of the procedure depends greatly on correct patient selection. It is particularly useful in cases where pain is related to epidural fibrosis, scar tissue adhesions or periradicular inflammation, while it may be less effective when pain results from mechanical instability, severe deformities or major structural compression.
Possible complications
Epiduroscopy is generally considered a safe procedure, but, like any invasive treatment, it can involve certain complications. Among the most common effects may be transient pain at the access site, low back discomfort, mild temporary worsening of radicular symptoms or headache.
Rarer complications include bleeding, infection, dural tear with cerebrospinal fluid leakage, irritation or injury to a nerve root, reactions to the medications used, or increased pressure in the epidural space during fluid infusion.
To reduce these risks, the procedure must be performed by experienced personnel, in a sterile environment and under radiological guidance.
Post-procedural course
After epiduroscopy, the patient is kept under observation for a few hours. In the absence of complications, discharge can take place on the same day or after a brief hospital stay, depending on the facility’s protocol and the patient’s clinical condition.
In the first 24-48 hours, relative rest is recommended, avoiding exertion, lifting weights and intense physical activity. Mild local soreness can be normal and generally tends to resolve on its own.
Improvement in pain may appear in the following days or more gradually over the following weeks. In some patients, the benefit is related both to the release of the adhesions and to the anti-inflammatory action of the medications administered.
Convalescence
The resumption of daily activities occurs progressively. Light walking can be resumed early, while sports or heavy work activities must be agreed upon with the specialist.
In many cases, after the procedure, a personalized rehabilitation program may be useful, aimed at restoring mobility, strengthening the paravertebral and abdominal muscles, improving posture and preventing recurrence of pain.
Treatment goal
The goal of epiduroscopy is to reduce chronic low back and radicular pain through a more direct assessment of the epidural space and targeted treatment of adhesions, inflammation and radicular irritation.
When correctly indicated, this procedure can represent a valid minimally invasive option for patients with persistent pain, especially after previous spinal surgery or in the presence of epidural fibrosis, helping to improve quality of life and daily function.
