Summary
Percutaneous endoscopic decompression for lumbar spinal stenosis showed significant clinical improvement in pain and disability. Long-term studies are needed to assess risks like instability and restenosis.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Limited research exists on two-portal percutaneous endoscopic decompression for lumbar spinal stenosis.
- This study addresses the gap by evaluating clinical outcomes.
Purpose of the Study:
- To report outcomes of lumbar spinal stenosis patients treated with percutaneous endoscopic decompression.
- Focus on clinical evaluation results and complications.
Main Methods:
- Retrospective review of 30 patients with lumbar spinal stenosis.
- Two-portal percutaneous endoscopic decompression using unilateral laminotomy for bilateral decompression.
- Analysis of clinical results using VAS, ODI, and Macnab criteria.
Main Results:
- All patients showed significant clinical improvement in pain (VAS) and disability (ODI).
- VAS improved from 8.3 to 2.3, and ODI from 65.2 to 24.0 (p<0.05).
- Complications were similar to open surgery, with transient nerve root paresthesia being most common.
Conclusions:
- Two-portal percutaneous endoscopic decompression offers initial benefits for lumbar spinal stenosis.
- Long-term studies are crucial to evaluate risks of instability, restenosis, and re-operation.
- Further investigation with long-term follow-up is required.
