(2025) .  \nAbstract  \nThis study aimed to develop machine learning (ML) models to predict the L5-S1 level recurrent lumbar disc herniation (rLDH) after percutaneous endoscopic interlaminar discectomy (PEID), a minimally invasive treatment for L5-S1 lumbar disc herniation. Data from 309 patients who underwent single-level L5-S1 PEID between January 2020 and June 2024, with at least 6 months of follow-up, were analyzed. Clinical records, preoperative imaging, and visual analog scale (VAS) scores were used. LASSO regression identified key predictors, and six ML models were built: support vector machine (SVM), decision tree (DT), adaptive boosting (ADA), light gradient boosting machine (LGBM), random forest (RF), and extreme gradient boosting (XGB) . Among the patients, 10.7% experienced rLDH, defined as ≥60% VAS reduction followed by symptom recurrence and imaging confirmation. Key predictors included Body Mass Index (BMI), posterior disc height index (PDHI), spinal canal stenosis, disease duration, numbness or weakness, Modic changes, herniation type, and diabetes. The RF and XGB models performed best. Higher BMI, Higher PDHI, spinal canal stenosis, disease duration over six months, Modic changes, non-contained herniation, and diabetes increased rLDH risk. Variable importance was ranked for both models. Predicting rLDH preoperatively can enhance decision-making and reduce recurrence risk after PEID, with ML models improving accuracy and identifying critical risk factors.  \nIntroduction  \nPercutaneous endoscopic lumbar discectomy (PELD) encompasses various techniques, such as percutaneous endoscopic transforaminal discectomy (PETD) and percutaneous endoscopic interlaminar discectomy (PEID), with the choice of surgical approach depending on the lesion location and individual anatomical characteristics of the patient1. Recurrent lumbar disc herniation (rLDH) is one of the most common reasons for  \nreoperation following PELD, with an incidence ranging from 0% to 12. 5%2,3 . As a minimally invasive technique, PEID has been widely applied in the treatment of lumbar conditions such as L5-S1 level disc herniation. Its advantages, including minimal trauma, short hospital stays, and rapid postoperative recovery, have made it highly favored by both clinicians and patients4. However, despite the significant benefits of endoscopic techniques in reducing surgical trauma and promoting quick recovery, some patients still face the issue of recurrent disc herniation post-surgery5.  \nThis PDF is WCAG 2.2 compliant  \nCopyright © 2025, Journal of Visualized Experiments [jove.com](jove.com) July 2025 • 221e68550 • Page 1 of 19  \nJournal of Visualized Experiments  \nChen et al.
