Endoscopic Spine Surgery

Neck and lower back pain are frequently managed without surgery. In many individuals, symptoms settle with medication and physiotherapy, along with modifications in daily activity.

In some patients, nerve compression does not settle with initial treatment. Ongoing pressure can produce radiating limb pain, numbness, or weakness. When these symptoms continue, surgical management may be explored. One minimally invasive option is endoscopic spine surgery, which allows access to the affected level through a small incision under camera guidance. Suitability for this method is determined only after careful clinical and imaging evaluation. Let’s understand it in detail.

Endoscopic spine surgery uses a small camera system introduced through a narrow tube. The surgeon views the operative field on a screen during the procedure.

Specialised instruments are passed through the same channel to remove the tissue causing nerve compression. Most commonly, this involves removing part of a herniated disc. In some cases, small portions of bone or ligament are trimmed to create additional space for the nerve.

This method may be considered in:

• Lumbar disc prolapse

• Cervical disc herniation

• Foraminal stenosis

• Selected spinal canal narrowing

• Certain recurrent disc cases

Because the incision is small and muscle disruption is limited, recovery patterns may differ from conventional open procedures.

Surgical management may be considered in patients with documented nerve compression who continue to experience symptoms despite adequate conservative treatment. It is generally not advised for back pain without signs of nerve compression.

Doctors may suggest this procedure when:

• Radiating arm or leg pain follows a typical nerve distribution

• A disc prolapse seen on MRI corresponds with clinical findings

• Ongoing numbness or weakness affects function

• Reduced walking tolerance is linked to nerve compression

• Symptoms recur after earlier disc intervention

A clear correlation between examination findings and imaging is required before proceeding with surgery. At Gleneagles Hospitals, treatment decisions are made after detailed clinical assessment and review of imaging studies.

The endoscopic technique is not appropriate in every spinal condition. Suitability varies according to the level involved and the nature of the problem.

Patients who may be evaluated include:

• Those with a single-level disc herniation

•  Individuals whose symptoms correspond with MRI findings

•  Patients who have completed non-surgical treatment without relief

•  People experiencing persistent radicular pain

•  Selected cases of foraminal narrowing suitable for targeted decompression

A detailed spine assessment helps determine whether this approach is appropriate.

In some situations, another surgical strategy may be more suitable. Endoscopic surgery may not be recommended in patients who:

• Have spinal instability requiring stabilisation

• Show marked spinal deformity

• Have extensive central canal narrowing

• Have an active infection of the spine

• Are medically unfit for anaesthesia

Alternative options are discussed when necessary.

Endoscopic spine surgery is performed by a spine surgeon trained in minimally invasive techniques. At Gleneagles Hospitals, the procedure takes place in an operating theatre equipped for spine surgery and continuous monitoring.

Before the operation, imaging studies are reviewed carefully. The surgical plan, expected outcomes, and potential risks are discussed with the patient. A review of medical history and current medications is undertaken as part of preoperative planning. Baseline blood investigations are performed prior to surgery.

Patients are commonly advised to:

• Food and fluids are avoided for several hours before surgery

• Any blood-thinning medicines should be discussed with the treating doctor

• Help at home during the first few days of recovery should be arranged

At Gleneagles Hospitals, patients are counselled about postoperative care and discharge before the procedure.

• Anaesthesia is administered in accordance with the surgical requirements.

• A limited skin incision is created at the identified spinal level. Imaging is used to guide the placement of the working channel. The endoscope then allows direct viewing of the affected nerve.

• The compressive disc material or tissue is removed carefully under visual control. After confirming decompression, the instruments are withdrawn, and the incision is closed in layers.

• The duration differs between cases. Cardiovascular and respiratory parameters are observed continuously.

Once surgery is completed, patients remain in the recovery room while the team observes their condition. In many cases, assisted mobilisation begins the same day, depending on comfort and neurological status.

Some effects noted after surgery may include:

• Mild soreness at the incision site

• A feeling of stiffness during early movement

• Occasional tingling that gradually settles

The duration of hospital stay is not uniform. Discharge may take place the same day in some cases, while others remain overnight for observation. Follow-up visits are arranged to assess healing and symptom improvement.

Although minimally invasive, endoscopic spine surgery carries recognised surgical risks. Complications are uncommon when appropriate selection and technique are applied.

Possible complications include:

• Infection

•  Bleeding

•  Temporary nerve irritation

•  Dural tear with cerebrospinal fluid leakage

•  Recurrent disc prolapse

At Gleneagles Hospitals, postoperative monitoring continues to ensure any concerns are addressed promptly.

This technique is used to relieve pressure on affected nerves while limiting disturbance to surrounding tissues. Possible benefits include:

• A smaller skin incision

• Less muscle handling during surgery

• Reduced postoperative discomfort in appropriate cases

• Shorter duration of hospital stay

• Quicker return to routine activities

Its use depends on whether the expected benefit matches the patient’s specific spinal condition.

Endoscopic spine surgery is part of Gleneagles Hospital's spine care services. The program involves spine surgeons trained in minimally invasive methods, with anaesthesia and perioperative support teams.

Facilities available include:

• Spine-designated operating theatres

• Imaging assistance during surgery

• Postoperative observation facilities

• Guidance for rehabilitation after discharge

At Gleneagles Hospitals, patients are assessed before surgery and continue under follow-up care as clinically required.

Endoscopic spine surgery is sometimes advised when a compressed nerve continues to cause discomfort, tingling, or weakness even after a reasonable trial of non-surgical treatment. Many patients first try medicines, rest, guided exercises, or injections. If these measures do not bring sufficient relief, a surgical option may then be discussed.

At Gleneagles, doctors carry out a detailed assessment. The dedicated spine team reviews the patient’s symptoms, examines them carefully, studies scan findings, and considers any existing medical conditions. Surgery is recommended only when these factors together suggest that the patient is likely to benefit from this technique.
