Evaluation of Lumbar Adhesiolysis Using a Radiofrequency Catheter During Epiduroscopy in the Treatment of Failed Back Surgery Syndrome (FBSS).
Surgical Technology International 2023 November 17
Failed back surgery syndrome (FBSS) is a complication of spinal surgery that results in severe and disabling back/leg pain. Epiduroscopy is a percutaneous minimally invasive surgical technique used in the treatment of lumbar radicular pain that enables both direct visualization of epidural adhesions in patients with FBSS and the mechanical release of fibrotic scars in the epidural space. Although the use of a balloon catheter during epiduroscopy can usually remove adhesions between the dura and the vertebrae, in the thickest areas of fibrosis, the use of a catheter with a molecular quantum resonance radiofrequency generator may resect hard epidural fibrotic obstructions. The aim of this study was to evaluate the efficacy and safety of this radiofrequency catheter in the treatment of severe epidural fibrotic scars. Ninety-three patients with FBSS were enrolled in this study. In 49 cases, a thick area of fibrosis was visualized during epiduroscopy and the use of a balloon catheter could not remove the fibrotic scars. In all of these cases, we used a molecular quantum resonance radiofrequency catheter to remove dense fibrotic areas. Intraoperatively during epiduroscopy, we could directly visualize lysis of the fibrotic scars. Immediately after the procedure and at 1-month and 6-month follow-up, the patients reported significant pain reduction. Pain reduction and patient satisfaction were also reported at 12 months in all but 5 cases. This study found a clinically relevant reduction of pain at 1 and 6 months after epiduroscopy in patients with FBSS. The use of a radiofrequency catheter is safe and effective in resection of hard and thick epidural scars.
