초록
Background: Patients with lumbar disc herniation are treated with physiotherapy/medication and some with surgery. However, even after technically successful surgery some develop a failed back syndrome with persistent pain. Our aim was to evaluate the efficacy of epiduroscopy in patients who suffer chronic low back pain and/or radicular pain with or without surgery and the gender difference in outcome.Methods: A total of 88 patients were included with a mean age of 52 years (27–82), 54 women and 34 men. 66 of them were operated previously and 22 were non-operated. They all had persistent chronic back pain and radicular pain despite of medication and physical rehabilitation. Visual Analog Scale (VAS) for pain and Oswestry Disability Index (ODI) were evaluated preoperatively, after one month, six months and one-year after the epiduroscopy. Results: All patients, and also the subgroups (gender and operated/non-operated) improved significantly in pain (VAS) and disability (ODI) at one month. A significant improvement was also seen at one year. No differences were found between men and woman at the different follow-up times. A slight worsening in VAS and ODI was noticed over time except for the non-operated group.Conclusions: Epiduroscopy helps to improve the back and leg pain due to lumbar disc herniation in the early stage. At one year an improvement still exists, and the non-operated group seems to benefit most of the procedure. (Korean J Pain 2018; 31: 109-15)
