Abstract:Objective To compare the efficacy，postoperative complications，quality of life，and subjective satisfaction between percutaneous endoscopic interlaminar discectomy（PEID）and the intervertebral foramen endoscopic broad，easy，and immediate surgery（BEIS）technique in the treatment of lumbar disc herniation （LDH）. Methods A prospective study was conducted on 100 LDH patients admitted to Huairou Hospital，Beijing Hospital of Traditional Chinese Medicine from January 2020 to January 2025. The patients were randomly divided into a PEID group（n=50）and a BEIS group（n=50）. Clinical efficacy，surgical parameters，pain intensity［Visual Analogue Scale（VAS）］，lumbar function［Oswestry Disability Index（ODI）and Japanese Orthopaedic Association（JOA）score］，quality of life［measured by Roland - Morris Disability Questionnaire（RMDQ）］，and postoperative complications were compared between the two groups. Results The overall response rate in the BEIS group was higher than that in the PEID group（94.00% vs 80.00%，χ²=4.332，P=0.037）. Operative time and blood loss were significantly lower in the BEIS group than those in the PEID group（P<0.05）. Postoperatively，VAS and ODI score were lower，and JOA score was higher in the BEIS group compared to the PEID group（P<0.05）. There was no statistically significant difference in the total incidence of postoperative complications between the two groups（8.00% vs 12.00%，χ²=0.444，P=0.505）. At 1 week，3 months，and 6 months postoperatively，RMDQ scores were lower in the BEIS group compared to the PEID group（P<0.05）. After surgery，subjective satisfaction was significantly higher in the BEIS group compared to the PEID group（92.00% vs 74.00%，χ²=4.536，P=0.033）. Conclusion The intervertebral foramen endoscopic BEIS technique achieves better clinical efficacy than PEID in the treatment of LDH，with superior improvement in surgical parameters，lumbar function，and pain relief.
