The usual site of obstruction is the ileocecal valve, though other sites have been reported. Here, we present two cases of gallstone ileus within the distal colon requiring surgical intervention. Two elderly females presented with vague abdominal symptoms secondary to large bowel obstruction from gallstone impaction. Both underwent attempted endoscopic retrieval without success. Patient 1 required laparoscopy converted to exploratory laparotomy with colotomy and removal of the stone. Patient 2 required partial colectomy and end colostomy formation due to acute sigmoid inflammation. Gallstone ileus is a rare cause of intestinal obstruction, though incidence increases with age. Cholecystocolonic fistulas allow stones to bypass the ileocecal valve, with the potential for impaction in the colon at the site of a stricture or tortuosity. Surgical intervention may be required in cases not amenable to successful endoscopic retrieval.<\/jats:p>","DOI":"10.1093\/jscr\/rjab137","type":"journal-article","created":{"date-parts":[[2021,4,26]],"date-time":"2021-04-26T19:22:47Z","timestamp":1619464967000},"source":"Crossref","is-referenced-by-count":8,"title":["Large bowel obstruction secondary to gallstones"],"prefix":"10.1093","volume":"2021","author":[{"given":"Matelin","family":"Crosen","sequence":"first","affiliation":[{"name":"Department of Surgery, Lehigh Valley Health Network, Allentown, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Ghattas","sequence":"additional","affiliation":[{"name":"Department of Surgery, Lehigh Valley Health Network, Allentown, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rovinder","family":"Sandhu","sequence":"additional","affiliation":[{"name":"Department of Surgery, Lehigh Valley Health Network, Allentown, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2021,5,18]]},"reference":[{"key":"2021070811422826500_ref1","article-title":"Gallstone ileus: management and clinical outcomes","volume":"55","author":"Jakubauskas","year":"2019","journal-title":"Medicina (Kaunas)"},{"key":"2021070811422826500_ref2","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2019-231581","article-title":"Gallstone ileus managed with enterolithotomy","volume":"12","author":"Dunphy","year":"2019","journal-title":"BMJ Case Rep"},{"key":"2021070811422826500_ref3","doi-asserted-by":"crossref","first-page":"737","DOI":"10.1002\/bjs.1800770707","article-title":"Gallstone ileus","volume":"77","author":"Clavien","year":"1990","journal-title":"Br J Surg"},{"key":"2021070811422826500_ref4","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.amsu.2018.01.004","article-title":"A systematic review of gallstone sigmoid ileus management","volume":"27","author":"Farkas","year":"2018","journal-title":"Ann Med Surg (Lond)"},{"key":"2021070811422826500_ref5","article-title":"Colonic gallstone ileus","volume":"2017","author":"Sigmon","year":"2017","journal-title":"BMJ Case Rep"},{"key":"2021070811422826500_ref6","doi-asserted-by":"crossref","first-page":"1533","DOI":"10.3748\/wjg.v16.i12.1533","article-title":"Successful endoscopic treatment of colonic gallstone ileus using electrohydraulic lithotripsy","volume":"16","author":"Zielinski","year":"2010","journal-title":"World J Gastroenterol"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jscr\/article-pdf\/2021\/5\/rjab137\/37952664\/rjab137.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jscr\/article-pdf\/2021\/5\/rjab137\/37952664\/rjab137.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,7,8]],"date-time":"2021-07-08T20:33:02Z","timestamp":1625776382000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjab137\/6276410"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,5,1]]},"references-count":6,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2021,5,1]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjab137","relation":{},"ISSN":["2042-8812"],"issn-type":[{"value":"2042-8812","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2021,5]]},"published":{"date-parts":[[2021,5,1]]},"article-number":"rjab137"}}
