ObjectiveTo assess postoperative outcomes and complications after percutaneous endoscopic lumbar discectomy (PELD) with or without epidural steroids (ES) administration in lumbar disc herniation.MethodsIn a double-blind randomized, placebo-controlled trial at Ramathibodi Hospital, Mahidol University, from May 2014 to May 2015, 30 patients were randomly allocated to receive ES or placebo (saline) after PELD. The primary outcome was 24-hour morphine consumption. Secondary outcomes were visual analog scale (VAS) scores for leg and back pain, Oswestry Disability Index score, Roland-Morris Disability Questionnaire score, and complications at 6-month follow-up.ResultsMean patient age was 60.0 years, and 0.57% of patients were male. Mean VAS back pain, VAS leg pain, Oswestry Disability Index, and Roland-Morris Disability Questionnaire scores at baseline were 4.7, 6.1, 24.9, 17.5 in the ES group and 5.1, 5.5, 24.7, 16.7 in the placebo group, respectively. Mean morphine requirements measured at 8, 16, and 24 hours were 3.47, 2.67, and <0.001 in the ES group and 3.13, 1.67, and 0.40 in the placebo group. The mean VAS scores measured at 4, 8, 12, 16, 20, and 24 hours were 2.99, 2.70, 2.56, 3.30, 3.05, and 2.05 the ES group and 3.13, 1.13, 1.26, 1.65, 1.22, and 1.08 in placebo group. The difference was not statistically significant (P > 0.05 for all).ConclusionsAdministration of ES with PELD for lumbar disc herniation does not improve postoperative pain, morphine requirements, or disability scores in the short-term and midterm periods.Copyright © 2018 Elsevier Inc.
