A Smaller Incision Does Not Mean the Same Surgery Is Right for Every Herniated Disc

Endoscopic lumbar discectomy is a minimally invasive procedure designed to remove the part of a herniated disc that is compressing a spinal nerve. This guide explains who may qualify, how the surgery is performed, possible risks, recovery, cost factors and how international patients can arrange an assessment in Istanbul.

Endoscopic Lumbar Discectomy in Turkey: Patient Guide

Pain that begins in the lower back and travels through the buttock, leg or foot may be caused by a lumbar herniated disc pressing on a spinal nerve.

Some patients improve with medication, rehabilitation, physiotherapy or image-guided treatments. Others may need microdiscectomy or endoscopic lumbar discectomy to release the compressed nerve.

However, finding a herniated disc on an MRI does not automatically mean that surgery is necessary.

Similarly, the fact that endoscopic surgery can be performed through a smaller access point does not mean that it is the best procedure for every patient.

The correct treatment decision depends on several questions:

Which nerve root is being compressed?
Does the patient’s pain pattern match the level seen on MRI?
Is there muscle weakness in the leg or foot?
Is the numbness or tingling progressing?
How far can the patient walk?
Have appropriate non-surgical treatments already been tried?
Can the disc fragment be reached safely with an endoscopic approach?
Is there spinal stenosis, vertebral slippage or instability?
Has the patient undergone previous lumbar surgery?
Is the main problem leg pain, back pain or both?

At Dr. Fatih Kırar’s clinic in Fulya, Istanbul, treatment planning is not based on the written MRI report alone. Symptoms, neurological examination, muscle strength, walking ability and the original MRI images are evaluated together.

Direct answer: Endoscopic lumbar discectomy may be considered when a lumbar disc herniation compresses a specific nerve root and causes radiating leg pain, numbness or weakness, provided that the location of the disc can be treated safely through an endoscopic approach. Not every herniated disc and not every patient is suitable for this procedure.

How Is the Decision for Endoscopic Lumbar Discectomy Made?

The decision begins by determining whether the herniated disc seen on MRI is actually responsible for the patient’s symptoms.

A lumbar MRI may show:

A central disc herniation
A right- or left-sided disc fragment
Foraminal narrowing
An extraforaminal disc herniation
A migrated disc fragment
A free or sequestered disc fragment
Spinal canal narrowing
Degenerative changes at several levels
Vertebral slippage
Previous surgical changes

Two patients may have a disc herniation at the same spinal level but require different treatments because the direction of the fragment, the degree of nerve compression and the neurological findings are different.

The operation should therefore be selected according to the anatomy and clinical findings, not simply because a patient has been told that an endoscopic technique is modern or uses a smaller incision.

What Is Endoscopic Lumbar Discectomy?

Endoscopic lumbar discectomy is a minimally invasive spinal procedure used to remove the disc material compressing a nerve root.

During the procedure, the surgeon introduces a narrow working tube and an endoscopic camera through a small skin opening. The camera provides a magnified view of the nerve root, disc and surrounding tissues on a monitor.

Specialised instruments are then used to:

Identify the disc fragment causing compression
Remove the necessary disc material
Release the affected nerve root
Preserve as much healthy tissue as possible
Confirm that the nerve has been adequately decompressed

The purpose of the operation is generally not to remove the entire spinal disc.

The goal is to remove the part that is pressing on the nerve while preserving the structures that do not need to be disturbed.

Further information about the technique can be linked to the Endoscopic Spine Surgery service page.

Is “Keyhole Disc Surgery” the Same as Endoscopic Surgery?

Patients may use terms such as:

Keyhole disc surgery
Closed disc surgery
Laser disc surgery
Minimally invasive disc surgery
Endoscopic disc surgery

These expressions are not always medically interchangeable.

“Keyhole” or “closed” surgery may refer to several different procedures, including:

Full-endoscopic discectomy
Microendoscopic discectomy
Microscopic discectomy
Percutaneous disc procedures
Minimally invasive decompression

The access route, equipment, anaesthesia and conditions treated by each method may differ.

Patients should therefore ask exactly which procedure is being recommended and why it is considered appropriate for their specific MRI findings.

Who May Be Suitable for Endoscopic Lumbar Discectomy?

Endoscopic discectomy may be discussed when a patient has:

A lumbar disc herniation compressing a specific nerve root
Sciatica travelling from the lower back or buttock into the leg
Numbness or tingling following a nerve distribution
Muscle weakness caused by nerve compression
Persistent symptoms despite appropriate non-surgical treatment
Pain affecting sleep, work or walking
MRI findings that match the neurological examination
A disc fragment that can be reached through an endoscopic corridor
A general health condition suitable for the proposed procedure and anaesthesia

Suitability is not determined by pain severity alone.

The surgeon must consider:

The spinal level
The direction of the disc fragment
The extent of nerve compression
The presence of spinal stenosis
Muscle strength
The duration of symptoms
Previous treatments
Previous spinal surgery
The patient’s age, occupation and general health

Does Every Herniated Disc Require Surgery?

No.

Many patients with lumbar disc herniation improve without an operation, especially when there is no progressive muscle weakness or emergency neurological condition.

Non-surgical treatment may include:

Temporary activity modification
Medication prescribed according to the patient’s condition
Physiotherapy and rehabilitation
A gradual exercise programme
Image-guided injections in selected cases
Interventional pain treatments
Monitoring of muscle strength and neurological symptoms

Surgery may become more relevant when symptoms remain disabling despite appropriate treatment or when neurological function is deteriorating.

Useful internal links for this section include:

When May Herniated Disc Surgery Be Necessary?

Surgery may be considered when the patient has:

Progressive weakness in the leg or foot
Foot drop
Severe and persistent radiating leg pain
Significant reduction in walking ability
Symptoms that interfere with sleep and daily activities
Insufficient improvement despite appropriate non-surgical treatment
Nerve compression that may threaten neurological function
New bladder or bowel dysfunction

The need for surgery and the type of surgery are separate decisions.

A patient may require nerve decompression but may not necessarily be suitable for the endoscopic technique. In some cases, microscopic surgery or a wider decompression may be safer.

Which Symptoms Require Urgent Medical Attention?

Patients should seek urgent assessment at the nearest emergency department if they develop:

Inability to urinate
New urinary incontinence
Loss of bowel control
Numbness around the inner thighs, genitals or saddle area
Rapidly progressing leg weakness
Sudden foot drop
Weakness affecting both legs
Inability to stand or walk
Severe pain accompanied by rapidly worsening neurological symptoms

These symptoms may indicate severe compression of the nerve bundle at the lower end of the spinal canal.

Patients experiencing these warning signs should not delay treatment while arranging international travel.

Who May Not Be Suitable for Endoscopic Discectomy?

A different surgical method may be more appropriate when the patient has:

Complex disc disease at several spinal levels
Severe spinal canal stenosis
Significant vertebral slippage
Spinal instability
Advanced spinal deformity
Extensive calcified compression
Certain highly migrated disc fragments
Significant scar tissue from previous surgery
A tumour, infection or fracture
Compression requiring wider decompression
Back pain that is not primarily caused by nerve compression
MRI findings that do not match the patient’s symptoms

Endoscopic surgery should not be selected simply because it uses a smaller entry point.

The chosen technique must provide enough access to decompress the nerve safely and adequately.

In some patients, Microsurgical Lumbar Discectomy may provide a more suitable working corridor.

How Are International Patients Assessed Before Travelling?

International patients do not always need to travel to Istanbul before their medical file has been reviewed.

A preliminary assessment can usually begin by sending:

The original lumbar MRI images
DICOM files or a digital imaging link
The written MRI report
Previous CT scans or X-rays
Electromyography results, if available
Previous operation reports
A list of current medications
Information about blood-thinning medication
Medical history and chronic conditions
A short explanation of symptoms

The patient should explain:

When the pain began
Whether the pain is mainly in the back or leg
Which leg is affected
How far the pain travels
Whether there is numbness or tingling
Whether the foot or toes feel weak
How far the patient can walk
Which treatments have already been tried
Whether previous spinal surgery has been performed
Whether bladder or bowel symptoms are present

The MRI report alone is not enough.

The surgeon usually needs to review the images themselves to understand the direction of the disc, the affected nerve and whether there are additional problems at other spinal levels.

The remote review is a preliminary assessment. The final diagnosis and surgical decision are confirmed after an in-person neurological examination in Istanbul.

What Happens During the Consultation in Istanbul?

The consultation may include:

Review of the patient’s symptom history
Neurological examination
Muscle strength testing
Sensory examination
Reflex testing
Assessment of heel and toe walking
Review of walking balance
Evaluation of the original MRI images
Review of previous treatments
Assessment of anaesthesia risks and general health

Additional examinations may be requested when necessary, including:

Standing X-rays
Flexion and extension X-rays
CT imaging
Updated MRI
Electromyography
Blood tests
Cardiology or internal medicine assessment

After the evaluation, the surgeon should explain:

The likely cause of the symptoms
Whether surgery is necessary
Whether endoscopic surgery is suitable
Whether microdiscectomy would be more appropriate
Whether spinal instability is present
Which symptoms may improve
Possible risks
Expected hospital stay and recovery
Alternative treatment options

How Is Endoscopic Lumbar Discectomy Performed?

The exact steps depend on the disc level, direction of the fragment and the chosen access route.

Confirming the Correct Spinal Level

Imaging is used before and during the procedure to confirm the correct disc level and plan the safest entry angle.

Anaesthesia

The procedure may be performed under general anaesthesia or, in selected techniques and patients, under local anaesthesia with sedation.

The choice depends on:

The spinal level
The surgical approach
The expected complexity
The patient’s medical condition
The anaesthetist’s assessment
The surgeon’s planned technique

Creating the Surgical Access

A small skin opening is made. Guide instruments and a working tube are advanced toward the target area under imaging guidance.

Introducing the Endoscope

The endoscopic camera is inserted through the working channel. The nerve, disc and surrounding tissues are viewed in magnified form on a monitor.

Removing the Compressing Disc Fragment

Special instruments are used to remove the disc material pressing on the nerve.

The aim is to remove the tissue causing compression rather than remove unnecessary disc or bone.

Confirming Nerve Decompression

After the disc fragment has been removed, the surgeon checks that the nerve root is adequately released.

Closing the Entry Site

The working tube and camera are removed, and the small skin opening is closed. The patient is then transferred to the postoperative observation area.

What Are the Main Endoscopic Approaches?

There are different routes for reaching the affected disc.

Transforaminal Approach

The surgeon reaches the disc from the side through a corridor near the opening where the spinal nerve exits.

This route may be considered for selected:

Foraminal disc herniations
Extraforaminal disc herniations
Lateral disc fragments
Disc herniations at suitable lumbar levels

Interlaminar Approach

The surgeon approaches from the back through the space between the posterior bony structures of the vertebrae.

This may be suitable for certain lower lumbar disc herniations, depending on the patient’s anatomy and the direction of the fragment.

The route is selected according to the safest and most effective way of reaching the compressed nerve.

Endoscopic Discectomy or Microdiscectomy: Which Is Better?

Both procedures aim to remove the disc material compressing the nerve.

The difference is mainly how the surgeon reaches and views the surgical area.

Endoscopic Lumbar Discectomy

Uses an endoscopic camera and working tube
Is performed through a limited access corridor
May reduce tissue disruption in selected cases
May support early mobilisation
Requires suitable anatomy and specialised experience

Microscopic Lumbar Discectomy

Uses a surgical microscope
Provides magnified direct visualisation
May provide a different or wider working area
May be more suitable for complex or difficult-to-reach fragments
May be preferred in selected revision procedures

Neither method is automatically better for every patient.

The correct procedure is the one that allows the nerve to be decompressed safely while addressing the actual cause of the patient’s symptoms.

What Are the Potential Advantages?

Possible advantages in suitable patients include:

A small skin incision
Limited disruption of surrounding muscles
A smaller visible scar
Reduced blood loss in many cases
Early mobilisation
A short hospital stay
Gradual return to daily activities
Preservation of healthy spinal structures where possible

These are potential benefits, not guaranteed outcomes.

Results depend on the disc location, duration of nerve compression, surgical complexity, patient age, general health and postoperative rehabilitation.

What Are the Risks?

Endoscopic lumbar discectomy is still a spinal operation and carries potential risks.

Possible complications include:

Infection
Bleeding or haematoma
Nerve irritation or injury
A tear in the membrane surrounding the nerves
Cerebrospinal fluid leakage
Incomplete removal of the compressing fragment
Persistent leg pain
Persistent numbness
Incomplete recovery of muscle weakness
Recurrent disc herniation
Need for additional surgery
Anaesthesia-related complications
Persistent back pain caused by another structure

A small incision does not eliminate surgical risk.

Patient selection, planning, surgical experience and hospital facilities remain important.

How Long Does the Operation Take?

There is no single operating time for every patient.

The duration may be affected by:

The spinal level
The location of the fragment
Migration of the disc material
The access route
Previous surgery
Scar tissue
Associated spinal stenosis
The number of levels involved
The patient’s anatomy

The quality of the operation should not be judged only by how quickly it is completed.

The main goal is safe and adequate decompression of the affected nerve.

When Can the Patient Walk?

Many patients can stand and begin controlled walking on the day of surgery or shortly afterwards, depending on their neurological condition and general health.

Before walking, the medical team may assess:

Leg and foot strength
Balance
Blood pressure and pulse
Recovery from anaesthesia
Pain control
Ability to urinate
The surgical wound

Early mobilisation does not mean that the patient can immediately return to heavy activity.

The first walks should be short and controlled.

Does Leg Pain Disappear Immediately?

Radiating leg pain caused by direct nerve compression may improve early after surgery.

However, different symptoms recover at different speeds:

Leg pain may improve first
Numbness may take weeks or months
Muscle weakness may recover more slowly
A nerve compressed for a long period may not recover completely
Back pain may continue if it comes from joints, muscles or disc degeneration

The operation removes the mechanical pressure on the nerve. The nerve then needs time to recover.

How Long Is the Hospital Stay?

Hospital stay depends on:

The type of anaesthesia
The extent of surgery
The patient’s age
Chronic medical conditions
Walking ability
Pain control
Neurological examination
Ability to urinate
The length of the patient’s planned journey

Some patients may leave on the same day or after short observation. Others may need one night or longer.

Discharge should be based on medical safety rather than a fixed package.

Recovery After Endoscopic Lumbar Discectomy

The First Day

The patient may begin short, controlled walks. The wound, leg strength, sensation and pain are monitored.

The First Week

Patients are usually encouraged to walk regularly for short periods.

They may be advised to avoid:

Prolonged sitting
Sudden twisting
Repeated bending
Heavy lifting
Strenuous exercise

The First Few Weeks

Walking time may be increased gradually.

Returning to an office-based job is different from returning to work involving heavy lifting, driving, construction or prolonged standing.

Later Recovery

A personalised rehabilitation programme may be recommended to improve:

Core strength
Hip and back mobility
Balance
Posture
Movement control
General conditioning

Recovery should not be based on a single online timetable. It depends on the duration of nerve compression, neurological findings, the extent of surgery and the patient’s occupation.

When Can the Patient Fly Home?

The timing of air travel depends on:

The length of the flight
Walking ability
Pain control
Wound condition
Risk of blood clots
Chronic medical conditions
Medication use
The need for an early postoperative review

International patients should not book an inflexible return flight before receiving a medical recommendation.

For longer flights, the medical team may provide individual instructions about movement, hydration and clot prevention.

Medication for blood clot prevention should not be taken without medical advice.

How Long Should International Patients Stay in Istanbul?

The recommended stay varies according to:

The patient’s preoperative condition
The type of surgery
Anaesthesia
Postoperative walking ability
Wound healing
Chronic illnesses
The length of the return journey
Whether an early follow-up examination is required
Whether the patient is travelling alone

Some patients may be medically ready to travel after a relatively short stay, while others need longer observation.

The return date should be confirmed after surgery rather than being decided only according to flight prices or accommodation arrangements.

Does the Patient Need a Companion?

A companion may be especially helpful when the patient:

Is older
Has leg weakness
Has chronic medical conditions
Is travelling to Turkey for the first time
Does not speak Turkish or English
Needs help carrying luggage
Is taking a long flight
Needs support with medication and mobility

The companion can also help remember postoperative instructions and communicate with the medical team.

What Should International Patients Bring?

Patients should prepare:

Passport and visa documents, if required
Original MRI images
DICOM files or digital imaging links
MRI reports
Previous surgical reports
A list of current medications and doses
Allergy information
Recent blood test results
Comfortable, loose clothing
Easy-to-wear shoes
Enough medication for chronic conditions
Contact information for a family member

Blood-thinning medication should not be stopped without instructions from the surgeon or prescribing doctor.

What Affects the Cost of Endoscopic Discectomy in Turkey?

The cost cannot be determined from the name of the procedure alone.

Factors that may affect the total cost include:

The spinal level
The number of levels
The location of the disc fragment
Whether it is a first or revision operation
The hospital and operating room
Anaesthesia
Endoscopic equipment and surgical materials
Preoperative tests
Length of hospital stay
Additional procedures
Translation and coordination services
Postoperative follow-up

International patients should request a written quotation explaining:

Surgeon’s fee
Anaesthesia
Hospital charges
Operating room charges
Surgical materials
Blood tests and imaging
Number of hospital nights
Medication
Follow-up examination
Medical reports
Translation
Transport or accommodation, if included
Services that are not included

Patients should not compare only the headline price.

A lower quotation may exclude anaesthesia, hospital charges, surgical materials or postoperative care.

Can the Treatment Plan Change After Arrival?

Yes.

A preliminary MRI review is useful for planning, but the final treatment decision is made after the in-person examination.

After arrival, the surgeon may determine that:

Surgery is not required
Non-surgical treatment should be tried first
Updated imaging is needed
Microdiscectomy is more appropriate
Wider decompression is required
Another spinal level is responsible for the symptoms
The pain is not primarily caused by the herniated disc

International patients should choose flexible travel arrangements whenever possible.

Follow-Up After Returning Home

Before leaving Turkey, the patient should receive:

A medical report
Medication instructions
Wound care instructions
Guidance on walking and sitting
Advice about sleeping positions
Warning signs requiring urgent medical attention
A plan for returning to work and driving
Rehabilitation recommendations
Follow-up contact information

Remote follow-up may include:

Updates about pain and walking
Photographs of the wound
Review of rehabilitation progress
Review of later imaging when required

However, remote follow-up cannot replace emergency medical care.

Patients should seek local medical attention if they develop:

New weakness
Fever
Wound redness or discharge
Difficulty urinating
Loss of bladder or bowel control
Severe calf swelling
Chest pain
Shortness of breath

Questions to Ask Before Surgery

International patients may ask:

Does my pain match the disc seen on MRI?
Which nerve is compressed?
Why is endoscopic surgery suitable for me?
What are the non-surgical alternatives?
Would microdiscectomy be more appropriate?
Is more than one spinal level affected?
Which part of the disc will be removed?
Is spinal instability present?
Will I need screws or fusion?
Which symptoms are expected to improve?
Could my back pain continue?
How long will I stay in hospital?
How long should I remain in Istanbul?
When can I fly?
Do I need a companion?
What does the quotation include?
How will follow-up be organised after I return home?

Frequently Asked Questions

Is endoscopic lumbar discectomy dangerous?

Every spinal operation has potential risks. Endoscopic surgery uses a limited access route, but infection, bleeding, nerve injury, dural tear, persistent symptoms and recurrent disc herniation remain possible.

Is every herniated disc suitable for endoscopic surgery?

No. Suitability depends on the level, direction and location of the disc, the type of nerve compression, spinal canal dimensions and spinal stability.

Is the entire disc removed?

Usually not. The part of the disc compressing the nerve is removed. Removing the entire disc is not the routine aim.

Are screws or implants required?

Not routinely for a simple disc herniation. Screws may be discussed if there is spinal instability, significant vertebral slippage or another structural problem.

Can the patient walk on the same day?

Many patients can begin controlled walking on the day of surgery, provided that their general and neurological condition is stable.

Does leg pain improve immediately?

Some patients experience early improvement in radiating leg pain. Numbness and muscle weakness may take longer because nerve recovery is gradual.

Is endoscopic surgery better than microdiscectomy?

There is no single best procedure for every patient. Endoscopic surgery may be suitable for one disc pattern, while microdiscectomy may provide safer or more complete access in another.

Can a large or sequestered disc be treated endoscopically?

Some extruded or sequestered disc fragments can be treated endoscopically. The location and migration of the fragment must be assessed.

Can the disc herniation return?

Yes. Recurrent disc herniation can occur after any type of discectomy.

Does endoscopic surgery treat back pain?

The primary aim is to relieve nerve compression. Back pain may continue if it comes from joints, muscles, disc degeneration or instability.

Can I send my MRI before travelling?

Yes. International patients can send the original MRI images, report and symptom information for a preliminary review. The final decision is made after an in-person examination.

How can I arrange an appointment in Istanbul?

Patients can prepare their MRI images and medical reports and use the Contact Dr. Fatih Kırar page to request an appointment or preliminary review.

Conclusion

Endoscopic lumbar discectomy in Turkey may be an option for selected patients with a lumbar disc herniation causing clear nerve compression, radiating leg pain, numbness or muscle weakness.

Its potential benefits may include a smaller access point, limited tissue disruption, early mobilisation and a short hospital stay.

However, success does not depend only on the size of the incision.

It depends on:

Correct diagnosis
Appropriate patient selection
Matching symptoms with MRI findings
A detailed neurological examination
Selecting the correct surgical route
Adequate decompression of the nerve
Appropriate postoperative rehabilitation

Not every herniated disc requires surgery, and not every disc requiring surgery should be treated endoscopically.

International patients considering treatment in Istanbul can send their MRI images and medical information for a preliminary assessment before travelling.
