Comparing Quality of Life: Discectomy Surgery versus Epidural Corticosteroid Injection for Lumbar Disc Herniation

Abstract

BackgroundSelecting an efficient treatment for patients with radiculopathy caused by lumbar disc herniation (LDH) unresponsive to conservative management remains a challenging task under investigation, yielding varying results. This study aims to compare the outcomes of the two most prevalent invasive treatments. MethodsIn this retrospective longitudinal study, we enrolled patients with confirmed refractory symptomatic LDH who sought treatment at Valiasr Hospital and underwent either discectomy surgery or epidural steroid injection (ESI) between 2019 and 2022. The outcome measures included pain intensity using the Visual Analog Scale (VAS) and quality of life (QoL) using the SF-36 questionnaire. ResultsA total of 202 individuals (112 in the discectomy group and 90 in the ESI group) consisting of 90 males and 112 females, with a mean age of 50.9 ± 13.5 years, underwent analysis. In the univariate analysis, QoL scores were significantly higher in the discectomy group (57.4 ± 2.4) compared to the ESI group (44.2 ± 2.4) (p <0.01). Furthermore, the surgery group exhibited a significantly greater reduction in the Leg VAS score after treatment compared to the ESI group (mean difference: -2.59, 95% confidence interval (CI): -3.45 to -1.70, p <0.01). After adjusting for the most important confounding variables using multiple linear regression analysis, the association between surgery and higher QoL scores remained statistically significant (Unstandardized Coefficients B= 7.65, 95% CI: 0.55, 14.76, p = 0.03). ConclusionsOur findings indicate that discectomy surgery has a more pronounced effect on patient outcomes and is a preferable treatment option for LDH patients.
