ObjectiveThe objective of this study was to compare the effectiveness and safety of local anesthesia (LA) and epidural anesthesia (EA) for percutaneous transforaminal endoscopic discectomy (PTED) and provide reference data for clinical decision-making.MethodsWe searched PubMed, EMBASE, the Cochrane library, Web of Science, Medline, Science Direct, and China National Knowledge Infrastructure from inception to March 2022 to identify randomized and nonrandomized controlled trials comparing LA and EA for PTED. Studies that assessed at least 2 of the following indicators were considered eligible: surgical duration, X-ray exposure time, satisfaction rate, visual analog scale scores for pain, Oswestry Disability Index, and complications. Meta-analysis was conducted using Review Manager 5.3.3 software.ResultsFive randomized controlled trials and 5 retrospective cohort studies involving a total of 1660 patients were included. The LA and EA groups included 803 and 857 patients, respectively. Meta-analysis revealed significant intergroup differences in the intraoperative lumbar visual analog scale scores (P < 0.00001) and anesthesia satisfaction rate (P < 0.00001). There were no significant intergroup differences in the surgical duration, X-ray exposure time, postoperative Oswestry Disability Index, and complication rate.ConclusionsEA is as safe as LA and produces better anesthetic effects than LA in patients undergoing PTED. Therefore, EA should be promoted as a reliable anesthetic technique for PTED.Copyright © 2022. Published by Elsevier Inc.
