Outcomes of epiduroscopic laser ablation in patients with lumbar disc herniation

Recently, trans-sacral epiduroscopic laser decompression (SELD) using flexible epiduroscopy and laser system is 1 of the options for minimally invasive surgery in herniated lumbar disc. However, outcomes after SELD in patients with disc herniation of lumbar spine are not proven worldwide. The authors reported clinical, surgical, and radiological outcome after SELD in patients with mild to moderate disc herniation. Between 2015 and 2018, eighty-two patients who underwent SELD for single level disc herniation with a minimum follow-up of 6.0 months were investigated retrospectively. Clinical outcomes were assessed using the visual analog scale for low back and leg pain and Odom's criteria for patient satisfaction. Also, surgical outcomes, including complications, recurrences, and revision surgeries, and radiological outcomes using regular simple radiograph were analyzed. The mean visual analog scale score of low back pain and leg pain improved from 5.43 ± 1.73 and 6.10 ± 1.67 to 2.80 ± 1.43 and 3.58 ± 2.08 at the final follow-up (p
