Risk Factors for Recurrent Disk Herniation After Biportal Endoscopic Diskectomy

Single-level biportal endoscopic diskectomy showed good clinical outcomes similar to previous studies. Intermediate symptomatic recurrence rate was 9.4%, whereas only 5% required repeat surgery. Risk factors for recurrence was similar to open and tubular techniques. Despite the minimally invasiveness and high visualization capabilities of biportal endoscopy, patients who are diabetic, smoker, or contained disk herniation on MRI should be counseled for higher risk of recurrence.
