Abstract: OBJECTIVE: To evaluate the association of body mass index (BMI) with the patient-reported outcomes (PROs) following percutaneous endoscopic lumbar discectomy (PELD). METHODS: Consecutive patients who underwent PELD from January 2017 to September 2021 were retrospectively studied. Based on the preoperative BMI, the patients were divided into 4 groups: thin group, normal group, overweighted group, and obese group.Baseline demographics, clinical features, and radiographic characteristics were collected. PROs were evaluated by satisfaction index, residual symptoms, visual analog scale (VAS), and Oswestry Disability Index (ODI) scores. RESULTS: A total of 346 patients were enrolled in the final analysis. There were 7 patients in thin group (2.0%), 128 patients in normal group (37%), 138 patients in overweighted group (40%), and 73 patients in obese group (21%). All patients were followed for more than 2 years. Postoperative VAS and ODI scores were improved in all groups (P < 0.05), there was no statistical significance among 4 groups at the final follow-up (P > 0.05). At the final follow-up, there were no statistically significant differences insurgical outcomes such as VAS scores, ODI scores, and recurrence rates. Correlation analysis revealed that BMI was not associated with VAS score (P = 0.220), ODI score (P = 0.965), satisfaction index (P = 0.864) and residual symptoms (P = 0.453) at 2 years follow-up years follow-up. CONCLUSIONS: PELD is a safe and effective minimally invasive technique for treating patients with lumbar disc herniation. There is no significant correlation between BMI and PROs or recurrence rates. Therefore, BMI should not influence clinical decisions regarding PELD treatment for lumbar disc herniation.
