Abstract：Objective To investigate the clinical effect of percutaneous endoscopic extraction of nucleus pulposus in the treatment of lumbar disc herniation. Methods A total of 80 patients with lumbar disc herniation admitted to the Orthopaedic Spine Department of Yongchuan Hospital Affiliated to Chongqing Medical University from July 2022 to October 2023 were selected as the study objects,and were divided into Group A (n=40) and Group B (n=40) by random number table method.The A group received fenestration of the laminae nucleus pulposus and the B group received percutaneous endoscopic extraction of nucleus pulposus. Perioperative indicators,Oswetry dysfunction index score (ODI),visual analogue score (VAS),efficacy evaluation and postoperative complications were statistically compared between the two groups. Results Compared with Group A,Group B had shorter incision length,less intraoperative blood loss,shorter hospital stay,and longer operation time,with statistically significant differences(P＜0.05). Both groups showed a decrease in VAS and ODI scores after surgery compared with preoperative scores,but the decrease in Group B was more obvious,with statistically significant differences(P＜0.05). The efficacy of Group B was better than that of Group A,and the incidence of complications was lower than that of Group A,with statistically significant differences(P＜0.05).Conclusion Both laminae nucleus pulposus and percutaneous endoscopic extraction of nucleus pulposuscan effectively treat lumbar disc herniation. Minimally percutaneous endoscopic extraction of nucleus pulposus has better therapeutic effects,lower complication rate,less intraoperative blood loss,shorter hospital stay,and less postoperative pain.
