The presence of common bile duct stones (CBDS) in this setting mandates definitive treatment to avoid complications such as cholangitis. The incidence of CBDS in the setting of AC is poorly defined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A systematic English literature search was conducted in PubMed, MEDLINE and Embase to determine the incidence of CBDS in patients presenting with AC. Outlier studies identified by funnel plot analysis were excluded and the incidence of CBDS was identified. The mean CBD diameter and liver function test values of patients with AC and CBDS were calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Data were extracted from 19 studies representing a total 4057 patients with AC. Routine biliary imaging was not performed in all studies. The pooled incidence of CBDS was 13.7% (95% confidence interval 11.8\u201315.9). The incidence of unsuspected retained CBDS was 1.1%. Histologically confirmed cases of AC had a similar rate of CBDS compared to those diagnosed clinically. The mean CBD diameter of patients with AC and CBDS was 7.2\u2009mm compared to 5.8\u2009mm without. Liver function test values in the presence of CBDS were more likely to be deranged, with gamma\u2010glutamyltransferase the most sensitive and specific marker for CBDS in the setting of AC.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>CBDS is present in a significant proportion of patients presenting with AC. Routine biliary imaging is advised in all patients presenting with AC where possible.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ans.15565","type":"journal-article","created":{"date-parts":[[2019,11,20]],"date-time":"2019-11-20T00:52:47Z","timestamp":1574211167000},"page":"1598-1603","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Incidence and predictors of common bile duct stones in patients with acute cholecystitis: a systematic literature review and meta\u2010analysis"],"prefix":"10.1111","volume":"90","author":[{"given":"Hongyi","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Surgery The University of Melbourne, Austin Health  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Jorissen","sequence":"additional","affiliation":[{"name":"Systems Biology and Personalised Medicine Division Walter and Eliza Hall Institute of Medical Research  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James","family":"Walcott","sequence":"additional","affiliation":[{"name":"Department of Surgery The University of Melbourne, Austin Health  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4866-276X","authenticated-orcid":false,"given":"Mehrdad","family":"Nikfarjam","sequence":"additional","affiliation":[{"name":"Department of Surgery The University of Melbourne, Austin Health  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,11,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1091-255X(01)80073-1"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1136\/gut.2007.121657"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1477-2574.2011.00317.x"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1308\/003588410X12628812458293"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1186\/s12893-016-0159-9"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2168.1998.00640.x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004640000311"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00534-006-1152-y"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9610(80)90428-6"},{"key":"e_1_2_7_11_1","first-page":"9","article-title":"Acute cholecystitis.
