Background: Neuroplasty using a Racz catheter or epiduroscope and percutaneous endoscopic laser discectomy are performed as treatment for chronic refractory low back and/or lower extremity pain, but they are limited in that they cannot completely remove the causing pathology. Lately, epiduroscopic laser neural decompression (ELND) has been receiving attention as an alternative treatment, but there are insufficient reports of results. Hence we aimed to investigate and report the data in our hospital. Methods: Seventy-seven patients were selected who had received ELND via the anterior and posterior epidural approach through the pain clinic in our hospital from March 2011 to July 2012. Their medical records including age, diagnosis, epiduroscopic findings and degree of symptom relief were investigated. The degree of symptom relief following the procedure was categorized into 5 stages of very good (5), good (4), no change (3), bad (2), and very bad (1) at 2 weeks and 1 month after the procedure. Results: The subjects were 30 males and 47 females. Mean age was 54.6 for males and 59.6 for females, so the overall mean age was 58.1 years old, with the youngest being 23 and the oldest 88 years old. In epiduroscopic images of all patients, more than one situation of herniated disc, fibrous tissue and adhesion, or inflammation was observed. Sixty-seven patients (87.0%) showed symptom relief 2 weeks after the procedure and 63 patients (81.8%) showed relief after 1 month. Conclusions: ELND is considered to be an effective treatment alternative for chronic refractory low back and/or lower extremity pain, including lumbar disc herniation, lumbar spinal stenosis, and failed back surgery syndrome which cannot be alleviated with existing non-invasive conservative treatment.
