Abstract
OBJECTIVE: This cohort study aims to evaluate the impact of obesity on the outcomes of full endoscopic lumbar discectomy (FELD) in patients with lumbar disc herniation. METHODS: We conducted a retrospective analysis of 156 adult patients who underwent FELD for lumbar disc herniation from January 2015 to February 2023. Patients were divided into 3 groups: obese endoscopic (n = 71), obese open surgery (n = 31), and nonobese endoscopic (n = 54). Clinical outcomes were assessed using the visual analog scale for leg and back pain, the Oswestry Disability Index, and patient satisfaction rates. Operative time, hospital stay duration, and complication rates were also analyzed. RESULTS: No significant differences were observed in patient-reported outcome measures, operative time, or complication rates between obese and nonobese patients undergoing FELD. The mean operative time was longer in the endoscopic group compared with the open surgery group (70.2 vs 59.8 minutes), but the hospital stay was significantly shorter for endoscopic patients (1.7 vs 2.4 nights, P = 0.0006). Both obese and nonobese groups showed significant improvements in visual analog scale and Oswestry Disability Index scores at the final follow-up, with satisfaction rates of 85.7% in the endoscopic group reporting good to excellent outcomes. CONCLUSIONS: FELD is a viable and effective alternative to traditional open surgery for obese patients, offering comparable clinical outcomes and the added benefit of a shorter hospital stay. These findings suggest that obesity does not inherently affect surgical outcomes, underscoring the need for further research with larger sample sizes and longer follow-up periods. CLINICAL RELEVANCE: FELD offers a viable and effective surgical option for obese patients, with outcomes comparable to traditional surgery but with the added benefit of shorter hospital stays.
