Summary
Endoscopic lumbar discectomy shows better short-term safety than microdiscectomy but has a higher reoperation rate within two years. Patients should weigh the immediate benefits against the long-term risk of repeat procedures.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
- Spinal Decompression
Background:
- Endoscopic lumbar discectomy (ELD) is a minimally invasive technique gaining traction.
- Limited large-scale data exist comparing ELD durability to traditional microdiscectomy (MD).
Purpose of the Study:
- To compare short-term complications and two-year reoperation rates between ELD and MD.
- Evaluate the long-term outcomes of minimally invasive versus traditional lumbar discectomy.
Main Methods:
- Retrospective cohort analysis of the TriNetX US Collaborative Network.
- 1:1 propensity score matching for adult patients undergoing ELD or MD for lumbar disc herniation (LDH).
- Analysis of 90-day complications and two-year reoperation rates (repeat decompression, fusion, post-laminectomy syndrome).
Main Results:
- ELD demonstrated significantly lower 90-day medical and surgical complications compared to MD.
- No significant difference in 90-day hospital readmission or emergency department visits.
- At two years, ELD showed a higher risk of repeat lumbar decompression and post-laminectomy syndrome, but similar lumbar fusion rates.
Conclusions:
- Endoscopic lumbar discectomy provides enhanced perioperative safety.
- However, it is associated with reduced two-year durability compared to microdiscectomy.
- Balancing short-term benefits with long-term reoperation risk is crucial when selecting surgical approaches.
