Endoscopic Lumbar Discectomy
Endoscopic Lumbar Discectomy is a minimally invasive surgical technique used to treat herniated or degenerated intervertebral discs in the lumbar spine. The procedure is designed to relieve nerve compression caused by disc material pressing on spinal nerve roots, alleviating symptoms such as lower back pain, sciatica, or leg pain.

Procedure Overview:
- Incision and Access:
A small incision (typically less than 1 cm) is made on the patient’s back to access the affected disc level. Using fluoroscopic guidance, a series of dilators are inserted to create a minimally invasive pathway to the spine, avoiding excessive muscle disruption. - Endoscopic Visualization:
A high-definition endoscope is introduced through a working channel, providing clear and magnified visualization of the herniated disc material, nerve roots, and surrounding structures. - Discectomy and Decompression:
Specialized instruments, such as forceps, reamers, and graspers, are used to carefully remove herniated or degenerated disc fragments that are compressing the nerve root. Adequate decompression is confirmed by visualizing the nerve root free of any impingement. - Foraminotomy (if necessary):
If the neural foramen is narrowed, a foraminotomy may be performed using small bone drills to enlarge the nerve passageway and further relieve nerve compression. - Closure:
After completing the decompression, the instruments are removed, and the incision is closed with absorbable sutures or adhesive strips. The procedure is typically performed on an outpatient basis.
Potential benefits
For appropriately selected patients, endoscopic lumbar discectomy may offer:
- Minimally invasive treatment: Less disruption of surrounding muscles and soft tissues.
- Quicker recovery: A potentially faster return to daily activities than with traditional open surgery.
- Meaningful symptom relief: Many patients experience improvement in nerve-related leg pain and function.
- Less blood loss: The focused approach typically reduces bleeding compared with more invasive surgery.
- Preservation of spinal movement: Disc fragments are removed without spinal fusion when fusion is not needed.
- Small incision and limited scarring: A small access opening reduces tissue disruption and may limit scar formation.
- Same-day discharge: Many patients go home after a few hours of observation, once the care team confirms it is safe.
Recovery and results vary with your condition, overall health and the procedure performed. Benefits are not guaranteed.
Indications:
This procedure is suitable for patients experiencing:
- Herniated or bulging discs causing nerve compression.
- Sciatica or radicular leg pain.
- Persistent symptoms unresponsive to conservative treatments such as physical therapy or injections.
Expected Outcomes:
Endoscopic lumbar discectomy aims to relieve pressure on a spinal nerve and improve pain and function. Recovery varies, and some patients have persistent symptoms or need further treatment. Dr. Lal will review the expected benefits, alternatives and risks, including infection, bleeding, nerve injury, spinal fluid leakage and recurrent disc herniation.
