Objective To explore percutaneous endoscopic lumbar discectomy (PELD) and Unilateral Biportal Endoscopy Technique. The clinical effect of UBE in the treatment of lumbar disc herniation (LDH). Methods: From September 2020 to January 2022, 22 LDH patients aged 36-68 years old were treated by surgery in our hospital. There were 12 cases of simple lumbar disc herniation and 10 cases of lumbar spinal stenosis. All patients were randomized to either PELD or UBE. The patients were evaluated using the JOA (Japanese Orthopaedic Society) achievement standard score for low back pain. The differences of JOA scores before surgery, 1 day after surgery and 12 months after surgery were compared. Results: All the 22 patients successfully completed the operation without serious complications. The follow-up time was 13±3 months. The follow-up showed that there were significant differences in the paired T-test of JOA branches in group A (t=-12.894, P=0.000). There were significant differences in the paired T-test of JOA scores in group B (t=-9.095, P=0.000). The JOA improvement index between the two groups was tested by independent sample t test, and the difference was not statistically significant (t=-1.269, P=0.219). The JOA improvement index of patients with lumbar spinal stenosis was statistically significant by inter-group independent sample t test (t=-2.887, P=0.020). Conclusion: Both PELD and UBE are effective in treating LDH. UBE technique is more effective in the treatment of LDH with lumbar stenosis.
