Endoscopic Spine Surgery vs Minimally Invasive Spine Surgery

Introduction:

Endoscopic spine surgery and minimally invasive spine surgery (MISS) are two modern surgical strategies for treating spinal conditions. Their differences lie in their approach:

• Endoscopic surgery employs a miniature camera and instruments, inserted through a tiny cut to access and mend the spine.
• MISS, on the other hand, uses slightly larger cuts but permits the surgeon to view and work on the spine with microscopes and specialised tools.

Both these techniques aim to reduce tissue damage and hasten recovery compared to traditional open spine surgeries. However, endoscopic surgery is often seen as more minimally invasive than the two.

The choice between endoscopic or MISS depends largely on your specific spinal condition and your surgeon’s expertise. It would be beneficial for you to discuss the merits and demerits of each method with your spine surgeon to determine the most suitable surgical option for your individual needs.

What is Endoscopic Spine Surgery?

Endoscopic Spine Surgery is an advanced surgical procedure, considered the least invasive among spine surgeries. This state-of-the-art technique employs a tiny camera, known as an endoscope, along with special instruments to treat various spinal conditions through minuscule incisions. The aim is to provide you with quicker recovery times and less recurring pain compared to traditional open-spine surgery.

What Happens in Endoscopic Spine Surgery:

• The surgeon makes a small cut, typically less than one inch.
• A tubular retractor is inserted to create a pathway reaching your spine.
• The endoscope, a slim 7mm tube fitted with a high-resolution camera lens and light source, is introduced through the retractor.
• Images from the endoscope are projected onto a monitor in the operation theatre (OT), helping the doctor to view your anatomy and identify any issues.

This procedure can effectively address several spinal conditions such as herniated discs, spinal stenosis, sciatica, and facet joint syndrome. However, remember that this form of surgery might not be suitable for some specific spinal conditions like scoliosis, spinal instability, cancer or trauma

What is Minimally Invasive Spine Surgery?

Minimally Invasive Spine Surgery, commonly known as MISS, is a modern surgical approach that treats various spinal conditions. Unlike traditional open spine surgery, MISS causes less disruption to surrounding muscles and tissues. Here are some of the key features:

• The surgery involves smaller incisions, typically less than 2-3 inches compared to the 5-6 inch incisions in open spine surgery.
• It uses specialised instruments and techniques like tubular retractors and endoscopic cameras to access the spine through these smaller openings.
• MISS minimises disruption to the muscles and soft tissues around the spine. This leads to less pain and blood loss for the patient, speeding up recovery times.
• MISS is capable of treating a variety of spinal conditions. These include herniated discs, spinal stenosis, spondylolisthesis, and even spinal deformities.

The primary goal of MISS is to achieve comparable surgical outcomes to traditional open spine surgery. However, it aims to cause less tissue damage and ensure quicker recovery for the patient. As an advanced and minimally invasive approach, MISS is often preferred over open spine surgery.

Advantages and Disadvantages of Endoscopic Spine Surgery

Endoscopic spine surgery, a minimally invasive procedure, has distinct benefits and limitations. Understanding these can help in making an informed decision if you are contemplating this type of surgery.

Advantages include:

• Smaller incisions, typically less than one inch, which lead to reduced tissue damage and scarring.
• Accelerated recovery times allowing for a quicker return to routine activities.
• Less blood loss and post-operative pain, resulting in more comfort post-surgery.
• Shorter hospital stays, often facilitating same-day discharge.
• The ability to treat various spine-related conditions such as herniated discs, stenosis, sciatica, and facet joint syndrome.
• Improved visualisation during surgery due to the endoscopic camera technology.
• Preservation of the normal range of spine mobility.

However, endoscopic spine surgery also has certain disadvantages:

• It includes a steep learning curve for surgeons which impacts the availability of experienced practitioners.
• Certain complex spinal conditions like trauma or severe deformities may not be suitable for endoscopic approaches.
• The long-term outcomes and complication rates are still under research as techniques continue to evolve.
• The procedure requires specialised equipment and training for surgical teams.
• Only a small number of surgeons have acquired the technical proficiency to perform these procedures effectively.

Advantages and Disadvantages of Minimally Invasive Spine Surgery (MISS)

Minimally Invasive Spine Surgery (MISS), as the name suggests, is a surgical procedure performed on the spine using techniques that minimise physical trauma to the patient. However, like any medical procedure, it comes with its fair share of advantages and disadvantages.

Advantages

• MISS offers smaller incisions, usually less than 2-3 inches, unlike traditional open surgery which can leave incisions up to 5-6 inches.
• There is less disruption to the muscles and soft tissues surrounding your spine, leading to less post-operative pain and a reduced need for pain medication.
• Recovery times are quicker with MISS. You’ll spend less time in hospital wards and require less rehabilitation.
• Fewer complications are experienced in MISS. For example, there’s less chance of excess blood loss, large scar formation, and physical therapy challenges.
• MISS can treat a variety of spinal conditions including herniated discs, stenosis, spondylolisthesis, and deformities.
• Lastly, it carries a lower risk of infection and blood clots compared to open surgery.

Disadvantages

• The procedures have a steep learning curve for surgeons.
• Not all spinal conditions are suitable for minimally invasive approaches. Cases such as spinal instability, trauma or complex deformities might still require traditional open surgery.
• The long-term outcomes and complication rates of MISS are still under study as these techniques continue to evolve.
• MISS requires specialised equipment and training for the surgical team.
• There’s potential for prolonged operative time and increased radiation exposure compared to open surgery.

Endoscopic or Minimally Invasive Spine Surgery – Which is Best for You?

Choosing the best option between endoscopic and minimally invasive spine surgery (MISS) can be tricky. Both are minimally invasive techniques, promising fewer complications, minimal tissue damage and quicker recovery compared to traditional open spine surgery.

Here are some key differences:

• Endoscopic surgery involves tiny incisions of less than 1 inch and uses a small camera, known as an endoscope, to view and operate on the spine.
• MISS, on the other hand, uses slightly larger incisions of 2-3 inches but employs specialised instruments like tubular retractors and microscopes.

What could influence your choice between Endoscopic or MISS?

• Your specific spinal condition: Certain ailments might be more suitable for one approach over the other.
• Your doctor’s expertise: Not all doctors have equal experience with both techniques.
• Personal factors: Your overall health status and personal preferences play a significant role.
• Available resources: The availability of required specialised equipment and technology is also crucial.
