The aim of this meta-analysis is to identify the benefits of ESPB in patients undergoing laparoscopic cholecystectomy (LC). The authors searched PubMed, EMBASE, CENTRAL, CINAHL, and Web of Science to identify all randomized controlled trials (RCTs) evaluating the effects of ESPB on postoperative pain after LC. Primary outcome was defined as 24 h cumulative opioid consumption. Secondary outcomes were pain scores and the incidence of postoperative nausea and vomiting (PONV). We estimated mean differences (MD) and odds ratio (OR) using a random-effects model. A total of 8 RCTs, including 442 patients, were included in the final analysis. Postoperative opioid consumption was significantly lower in the ESPB group than in the control group (MD \u22124.72, 95% CI \u22126.00 to \u22123.44, p &lt; 0.001). Compared with the control group, the ESPB group also showed significantly lower pain scores and incidence of PONV. A separate analysis of RCTs comparing ESPB with oblique subcostal transversus abdominis plane (OSTAP) block showed that the analgesic efficacy of ESPB was similar to that of OSTAP block. The results of this meta-analysis demonstrated that ESPB may provide effective postoperative analgesia in patients undergoing LC.<\/jats:p>","DOI":"10.3390\/jcm9092928","type":"journal-article","created":{"date-parts":[[2020,9,10]],"date-time":"2020-09-10T22:58:01Z","timestamp":1599778681000},"page":"2928","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["The Effects of Erector Spinae Plane Block in Terms of Postoperative Analgesia in Patients Undergoing Laparoscopic Cholecystectomy: A Meta-Analysis of Randomized Controlled Trials"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8567-5514","authenticated-orcid":false,"given":"Chang-Hoon","family":"Koo","sequence":"first","affiliation":[{"name":"Department of Anesthesiology &amp; Pain Medicine, Seoul National University Bundang Hospital, Seongnam 13620, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin-Young","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology &amp; Pain Medicine, SMG-SNU Boramae Medical Center, Seoul 07061, Korea"},{"name":"Department of Anesthesiology &amp; Pain Medicine, Seoul National University College of Medicine, Seoul 03080, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0991-7061","authenticated-orcid":false,"given":"Hyun-Jung","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology &amp; Pain Medicine, Seoul National University Bundang Hospital, Seongnam 13620, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9331-5658","authenticated-orcid":false,"given":"Jung-Hee","family":"Ryu","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology &amp; Pain Medicine, Seoul National University Bundang Hospital, Seongnam 13620, Korea"},{"name":"Department of Anesthesiology &amp; Pain Medicine, Seoul National University College of Medicine, Seoul 03080, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,10]]},"reference":[{"key":"ref_1","unstructured":"Cullen, K.A., Hall, M.J., and Golosinskiy, A.
