    BackgroundData on the effectiveness of erector spinae plane block (ESPB) for patients undergoing liver surgeries is limited and inconclusive. We hereby aimed to systematically review if ESPB can provide adequate analgesia after liver surgery.MethodsPubMed, CENTRAL, Scopus, Embase, and gray literature were examined up to 25th April 2023 for randomized controlled trials (RCTs) comparing ESPB with control or spinal analgesia.ResultsNine RCTs were included of which three compared ESPB with spinal analgesia. 24-hour opioid consumption did not differ significantly between ESPB vs. control (MD: -35.25 95% CI: -77.01, 6.52 I2 = 99%) or ESPB vs. spinal analgesia (MD: 2.32 95% CI: -6.12, 10.77 I2 = 91%). Comparing pain scores between ESPB and control, a small but significant effect favoring ESPB was noted at 12 h and 48 h, but not at 6-8 h and 24 h. Pain scores did not differ between ESPB and spinal analgesia. The risk of postoperative nausea and vomiting was also not significantly different between ESPB vs. control or spinal analgesia. GRADE assessment shows moderate certainty of evidence.ConclusionESPB may not provide any significant postoperative analgesia in liver surgery patients. There was a tendency of reduced opioid consumption with ESPB. Limited data also showed that ESPB and spinal analgesia had no difference in pain scores and 24-hour analgesic consumption.© 2024.
