Clinical Efficacy and Safety of Trans-Sacral Epiduroscopic Laser Decompression Compared to Percutaneous Epidural Neuroplasty

Figure 4

Comparison of VAS scores for leg pain between the SELD and PEN groups preoperatively and at 4, 12, and 24 weeks after treatment; statistically significant differences were observed at 24 () weeks postoperatively. SELD = trans-sacral epiduroscopic laser decompression; PEN = percutaneous epidural neuroplasty; VAS = visual analog scale; POD = postoperative duration.
