Therefore, we aimed to compare RCD and LCD in terms of the associated clinical features. We retrospectively collected clinical data from patients who were diagnosed with acute colonic diverticulitis based on computed tomography findings between 2011 and 2017. RCD was defined as colonic diverticulitis extending from the caecum to the transverse colon, and LCD was defined as extending from the splenic flexure to the sigmoid colon. These analyses included 667 patients with RCD and 58 patients with LCD. Relative to the patients with LCD, the patients with RCD were younger (P\u2009&lt;\u20090.001), were more likely to be male (P\u2009=\u20090.033), were taller (P\u2009&lt;\u20090.001), had lower body mass index values (P\u2009&lt;\u20090.001), had less advanced modified Hinchey stages (P\u2009&lt;\u20090.001), and had shorter hospital stays (P\u2009&lt;\u20090.001). Having LCD rather than RCD was a predictor of recurrent colonic diverticulitis (P\u2009=\u20090.003). Relative to LCD, RCD occurs at younger ages, is expressed at less advanced modified Hinchey stages, and is associated with lower risks of recurrence.<\/jats:p>","DOI":"10.1038\/s41598-020-60397-5","type":"journal-article","created":{"date-parts":[[2020,2,28]],"date-time":"2020-02-28T11:02:41Z","timestamp":1582887761000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Difference in Clinical Features between Right- and Left-Sided Acute Colonic Diverticulitis"],"prefix":"10.1038","volume":"10","author":[{"given":"Kil-yong","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaeim","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youn Young","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Younglim","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seong Taek","family":"Oh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,2,28]]},"reference":[{"key":"60397_CR1","doi-asserted-by":"publisher","first-page":"1309","DOI":"10.1007\/s11605-008-0492-0","volume":"12","author":"CP Heise","year":"2008","unstructured":"Heise, C.
