Abstract:
Various percutaneous techniques to approach the lumbar disc were studied in the past. Chemonucleolysis, laser vaporization, lateral endoscopic foraminal approaches and different techniques of percutaneous nucleotomy remained disappointing due to insufficient root visualization, insufficient decompression or insufficient disc removal. The microendoscopic discectomy is performed via a median approach that allows thorough root exploration, direct evaluation of the compression and determination of contained or non-contained disc material. This is achieved by applying open surgical tools through a tubular retractor under endoscopic visualization. The endoscope is inserted via a sequential set of dilators passed over the initial guide wire. The technique allows a smaller incision and less tissue trauma with comparable visualization of the nerve structures than does standard open surgery.
Insights
Microendoscopic discectomy offers improved lumbar disc treatment. This minimally invasive technique provides thorough visualization and decompression, surpassing previous percutaneous methods for better patient outcomes.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Previous percutaneous lumbar disc techniques (chemonucleolysis, laser, nucleotomy) had limitations.
- These limitations included insufficient visualization, decompression, or disc removal, leading to disappointing outcomes.
Purpose of the Study:
- To evaluate the efficacy of microendoscopic discectomy for lumbar disc herniation.
- To compare microendoscopic discectomy with traditional open surgery regarding visualization and tissue trauma.
Main Methods:
- Microendoscopic discectomy performed via a median approach using a tubular retractor.
- Open surgical instruments used under endoscopic visualization for thorough root exploration and decompression.
- Sequential dilators used to insert the endoscope over a guide wire.
Main Results:
- Achieved thorough nerve root exploration and direct evaluation of compression.
- Enabled determination of contained or non-contained disc material.
- Resulted in a smaller incision and less tissue trauma compared to standard open surgery.
Conclusions:
- Microendoscopic discectomy provides comparable visualization to open surgery with reduced invasiveness.
- This technique offers a viable alternative for treating lumbar disc herniations effectively.
