Summary
Percutaneous endoscopic revision effectively treats recurrent L4/5 disc herniation after initial surgery. Percutaneous endoscopic interlaminar discectomy offers shorter operation and fluoroscopy times, making it a preferred option for recurrent lumbar disc herniation.
Area of Science:
- Neurosurgery
- Minimally Invasive Spine Surgery
- Spinal Endoscopy
Background:
- Recurrent lumbar disc herniation (rLDH) after initial discectomy presents a clinical challenge.
- Revision surgery is often necessary to manage persistent or recurring symptoms.
Purpose of the Study:
- To compare the efficacy and outcomes of two endoscopic revision techniques for L4/5 recurrent disc herniation (rLDH) following prior percutaneous endoscopic transforaminal discectomy (PETD).
- To evaluate the clinical outcomes of revision surgery using PETD versus percutaneous endoscopic interlaminar discectomy (PEID).
Main Methods:
- A retrospective study included 96 patients with L4/5 rLDH after PETD, divided into PETD (57 cases) and PEID (39 cases) revision groups.
- Clinical outcomes were assessed using Visual Analogue Scale (VAS) for pain, Oswestry Disability Index (ODI), and modified MacNab criteria.
Main Results:
- Both PETD and PEID groups showed significant postoperative improvement in VAS, ODI, and JOA scores compared to preoperative values.
- The PEID group demonstrated significantly shorter operative and fluoroscopy times compared to the PETD group, with no significant difference in blood loss.
- No serious complications were reported during follow-up in either group.
Conclusions:
- Percutaneous endoscopic revision techniques provide satisfactory outcomes for L4/5 rLDH after initial PETD.
- PEID is a potentially preferred revision method due to reduced operative and fluoroscopy times and avoidance of scar tissue from the initial surgery.
- Tailored surgical strategies are essential for specific herniation types during revision endoscopy.
