However, the results of the intercomparison of the two techniques for analgesia after abdominal surgery remain controversial.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A systematic literature search was performed on five databases for randomized controlled trials comparing the analgesic efficacy of ESPB and QLB in abdominal surgery. The primary outcome was the 24 h postoperative intravenous IV morphine\u2010equivalent consumption. A meta\u2010analysis was performed using a random\u2010effects model, with subgroup analyses based on the types of surgery and approaches of QLB.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The 24 h postoperative IV morphine\u2010equivalent consumption was lower in patients receiving ESPB than in those receiving QLB (MD \u20132.307\u00a0mg; 95% CI \u20124.577 to \u22120.038; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.046; and <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a096.5%), though the reduction did not reach clinically meaningful difference. Static and dynamic pain at different postoperative time points, the time to first rescue analgesia, and the incidence of PONV showed no significant difference between the two groups. However, the QLB group demonstrated a significantly prolonged time in performing the block compared to the ESPB group (MD \u20132.985\u00a0min; 95% CI \u20134.608 to \u20131.363; <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001; and <jats:italic>I<\/jats:italic><jats:sup>2<\/jats:sup>\u00a0=\u00a097.5%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Based on the available evidence from a systematic search of databases, the single\u2010shot ESPB exhibits similar analgesic effects as QLB in abdominal surgery.
