Twenty cattle had had an omentopexy or pyloropexy performed 1 day to 2 years before initial evaluation. Cattle were afebrile, tachycardic, and moderately dehydrated, with a small zone of percussion with a ping at the 10th to 12th right intercostal spaces and associated succussion. Biochemical changes were a severe hypokalemic (mean \u00b1 SD, 2.9 \u00b1 0.5 mmol\/L; median, 3.1 mmol\/L; range, 2.08 to 3.92 mmol\/L), hypochloremic (mean, 69.7 \u00b1 11.1 mmol\/L; median, 71.7 mmol\/L; range, 49.1 to 94.1 mmol\/L) metabolic alkalosis (mean total CO<jats:sub>2<\/jats:sub>, 44.5 \u00b1 7.4 mmol\/L; median, 45.3 mmol\/L; range, 31.5 to 59.6 mmol\/L) and hyperbilirubinemia (mean, 32.4 \u00b1 29.0 \u03bcmol\/L; median, 20.5 \u03bcmol\/L; range, 7.8 to 107 \u03bcmol\/L). Surgical findings for DSFV included an empty descending duodenum adjacent to a dorsally displaced and dilated cranial segment of the duodenum, distended abomasum and gallbladder, and a tight volvulus at the base of the duodenal sigmoid flexure. Manual reduction was considered successful if the descending duodenum filled after cranial duodenal massage. Twenty-two patients were successfully treated; the remaining 7 died or were euthanized within 4 days after surgery.<\/jats:p>\n<jats:p><jats:bold>Conclusions and Clinical Relevance<\/jats:bold>\u2014A condition clinically resembling abomasal volvulus but affecting the duodenal sigmoid flexure has been recognized in dairy cattle. When a focal, dorsal right-sided ping and succussion are present combined with severe hypokalemic, hypochloremic metabolic alkalosis and high bilirubin concentration, DSFV should be suspected, especially when there is a history of prior abomasal fixation. After surgical correction, the prognosis is fair to good.<\/jats:p>","DOI":"10.2460\/javma.241.5.621","type":"journal-article","created":{"date-parts":[[2012,8,23]],"date-time":"2012-08-23T15:05:11Z","timestamp":1345734311000},"page":"621-625","source":"Crossref","is-referenced-by-count":22,"title":["Duodenal obstruction caused by duodenal sigmoid flexure volvulus in dairy cattle: 29 cases (2006\u20132010)"],"prefix":"10.2460","volume":"241","author":[{"given":"Susan R.","family":"Vogel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylvain","family":"Nichols","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9bastien","family":"Buczinski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9","family":"Desrochers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie","family":"Babkine","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manon","family":"Veillette","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Francoz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Dor\u00e9","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gilles","family":"Fecteau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anne-Marie","family":"B\u00e9langer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauricio","family":"Badillo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1272","reference":[{"key":"ref1","series-title":"Textbook of veterinary anatomy","first-page":"139","volume":"129","author":"Dyce","year":"2002"},{"key":"ref2","series-title":"Duodenal obstruction caused by malposition of the gallbladder in a heifer","first-page":"1475","volume":"223","author":"Boerboom","year":"2003"},{"key":"ref3","series-title":"Clinical signs, diagnosis and treatment of duodenal ileus in cattle","first-page":"345","volume":"135","author":"Braun","year":"1993"},{"key":"ref4","series-title":"Comparison of naturally occurring proximal duodenal obstruction and abomasal volvulus in dairy cattle","first-page":"226","volume":"17","author":"Garry","year":"1988"},{"key":"ref5","series-title":"Functional stenosis of the sigmoid curve of the duodenum in cattle","first-page":"452","volume":"112","author":"van der Velden","year":"1983"},{"key":"ref6","series-title":"Surgical treatment of gastroduodenal obstructions in foals","first-page":"205","volume":"15","author":"Orsini","year":"1986"},{"key":"ref7","series-title":"Experimentally induced intestinal obstruction in sheep: paradoxical aciduria in metabolic alkalosis","first-page":"663","volume":"36","author":"Gingerich","year":"1975"},{"key":"ref8","series-title":"Experimental intestinal obstruction in calves","first-page":"210","volume":"74","author":"Hammond","year":"1964"},{"key":"ref9","series-title":"Description of 14 cases of bovine hypokalaemia syndrome","first-page":"503","volume":"143","author":"Sattler","year":"1998"}],"container-title":["Journal of the American Veterinary Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/avmajournals.avma.org\/view\/journals\/javma\/241\/5\/javma.241.5.621.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/avmajournals.avma.org\/downloadpdf\/journals\/javma\/241\/5\/javma.241.5.621.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/avmajournals.avma.org\/downloadpdf\/journals\/javma\/241\/5\/javma.241.5.621.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,7]],"date-time":"2025-03-07T11:36:50Z","timestamp":1741347410000},"score":1,"resource":{"primary":{"URL":"https:\/\/avmajournals.avma.org\/view\/journals\/javma\/241\/5\/javma.241.5.621.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,9,1]]},"references-count":9,"journal-issue":{"issue":"5"},"URL":"https:\/\/doi.org\/10.2460\/javma.241.5.621","relation":{},"ISSN":["0003-1488"],"issn-type":[{"value":"0003-1488","type":"print"}],"subject":[],"published":{"date-parts":[[2012,9,1]]}}}
