We included comparative studies of emergency minimally invasive versus open colectomy for complicated diverticulitis (Hinchey II\u2013IV).

Minimally invasive surgery was associated with lower 30-day mortality (4.5% vs. 8.7%; RR 0.48, 95% CI 0.40\u20130.59;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.0002; I\u00b2=0%; low certainty); this estimate derived 86.9% of its weight from one database study and was no longer statistically significant when that study was excluded (RR 0.61, 95% CI 0.35\u20131.06). Major complications did not differ significantly (15.2% vs. 17.7%; RR 0.63, 95% CI 0.36\u20131.08;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.10; very low certainty).

The mortality estimate derived most of its statistical weight from one large database study; after excluding that study, the point estimate remained favorable but imprecise. Overall certainty was low to very low, so these findings are hypothesis-generating rather than practice-changing. Minimally invasive resection may be considered in hemodynamically stable, selected patients operated on by surgeons with advanced laparoscopic colorectal expertise, pending prospective validation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Systematic review registration<\/jats:title>\n                    <jats:p>PROSPERO CRD420251142546.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12893-026-04043-3","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T10:45:24Z","timestamp":1784630724000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Emergency minimally invasive versus open left-sided colonic resection for complicated diverticulitis: a systematic review and meta-analysis"],"prefix":"10.1186","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-3626-1047","authenticated-orcid":false,"given":"Hariruk","family":"Yodying","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vichit","family":"Viriyaroj","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thammanij","family":"Rookkachart","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thana","family":"Boonsinsukh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anuwat","family":"Chartkitcharoen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wannakorn","family":"Prapasajchavet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natchanok","family":"Mekrugsakit","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patcharaon","family":"Petchkaewkul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ratchanon","family":"Laojanun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,7,21]]},"reference":[{"issue":"5","key":"4043_CR1","doi-asserted-by":"publisher","first-page":"1282","DOI":"10.1053\/j.gastro.2018.12.033","volume":"156","author":"LL Strate","year":"2019","unstructured":"Strate LL, Morris AM.
