Summary
Percutaneous endoscopic interlaminar discectomy (PEID) offers effective treatment for recurrent lumbar disc herniation (RLDH). This minimally invasive approach significantly improved pain and function in patients with RLDH at L4-L5 and L5-S1.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
Background:
- Recurrent lumbar disc herniation (RLDH) presents challenges including epidural scarring and instability.
- Endoscopic spine surgery offers advantages over open revision, such as enhanced visualization and reduced tissue trauma.
Purpose of the Study:
- To evaluate the effectiveness of percutaneous endoscopic interlaminar discectomy (PEID) for RLDH at the L4-L5 and L5-S1 levels.
Main Methods:
- A cohort of 64 consecutive RLDH patients underwent PEID.
- Clinical outcomes were assessed using the visual analogue scale (VAS) for pain, Oswestry Disability Index (ODI), and modified MacNab criteria over a 2-year follow-up.
Main Results:
- Significant improvements were noted in VAS pain scores and ODI post-PEID.
- At 2-year follow-up, 56 of 64 patients achieved excellent or good outcomes per modified MacNab criteria, with 4 fair and 4 poor outcomes.
Conclusions:
- PEID demonstrates favorable clinical outcomes for RLDH at L4-L5 and L5-S1 levels.
- Endoscopic discectomy is a viable option for revision spine surgery.
