Will percutaneous endoscopic lumbar discectomy reduce the risk of my lumbar disc herniation recurring?
Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive surgery to remove a herniated disc fragment. While it can relieve pain and improve function, the risk of the disc herniating again (recurrence) is a common concern. Research shows that the overall recurrence rate after PELD is about 11%, and it is not significantly lower than with open surgery. However, your personal risk depends on factors like smoking, diabetes, weight, and age.
What the research says
A large meta-analysis of 39 studies involving 14,454 patients found that the overall recurrence rate after PELD was 11.0% 2. This same analysis identified several factors that increase the risk of recurrence: Modic changes (bone marrow changes near the disc), diabetes mellitus, smoking, intraoperative annulus fibrosus rupture, greater spinal motion, higher body mass index (BMI), and advanced age 2. Another meta-analysis comparing endoscopic to conventional open discectomy for recurrent herniations found no significant difference in re-recurrence rates between the two approaches 5. This suggests that PELD does not inherently reduce recurrence risk compared to open surgery. However, a retrospective study of 107 patients showed that PELD resulted in less blood loss, shorter hospital stays, and better early pain and function scores than open surgery 4. While these benefits are important, they do not translate to a lower recurrence risk. Additionally, a study on surgical site infection after PELD noted that high BMI, diabetes, and long surgical time are risk factors for infection, which could complicate recovery 6.
What to ask your doctor
- Based on my age, weight, and health conditions, what is my personal risk of disc re-herniation after PELD?
- Do I have any Modic changes on my MRI that might increase recurrence risk?
- How does the recurrence rate of PELD compare to other surgical options for my specific type of herniation?
- What steps can I take before and after surgery to lower my risk of recurrence, such as quitting smoking or losing weight?
- If I have diabetes, how will my blood sugar control affect my surgical outcomes and recurrence risk?
