During large\u2010colon torsion, the colon wall becomes thick due to vascular occlusion. Therefore, we hypothesized that detecting increased colon wall thickness during ultrasonography would be an accurate preoperative test for large\u2010colon torsion. The sample population consisted of 42 horses that were admitted for surgical treatment of colic localized to the large colon. The diagnosis was confirmed at surgery or necropsy examination. Twelve (29%) of these horses were diagnosed with large\u2010colon torsion. Duplicate ultrasonographic measurements of colon wall thickness were made at six abdominal locations and an average measurement was calculated. For four of these six sites, a significant difference (<jats:italic>P<\/jats:italic>&lt;0.005) was detected between horses with and without large\u2010colon torsion. All four tests were moderately sensitive and highly specific for diagnosing large\u2010colon torsion using five decision criteria. Using a ventral abdominal window, a colon wall thickness \u22659\u2003mm accurately predicted large\u2010colon torsion in eight of the 12 horses (sensitivity, 67%; confidence interval [CI], 36\u201398%) and correctly predicted that large\u2010colon torsion was absent in 28\/28 horses (specificity 100%; CI, 98\u2013100%). Intraobserver repeatability was assessed by evaluating the difference between the first and second measurements obtained, which was \u22642\u2003mm. Therefore, detecting increased large\u2010colon wall thickness during ultrasonography is a reproducible and accurate preoperative test for large\u2010colon torsion in horses with surgical colic localized to the large colon.<\/jats:p>","DOI":"10.1111\/j.1740-8261.2004.04038.x","type":"journal-article","created":{"date-parts":[[2004,5,25]],"date-time":"2004-05-25T18:24:42Z","timestamp":1085509482000},"page":"220-224","source":"Crossref","is-referenced-by-count":50,"title":["Accuracy of increased large\u2010intestine wall thickness during ultrasonography for diagnosing large\u2010colon torsion in 42 horses"],"prefix":"10.1111","volume":"45","author":[{"given":"Anthony P.","family":"Pease","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter V.","family":"Scrivani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hollis N.","family":"Erb","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanessa L.","family":"Cook","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,5,25]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.1997.tb03157.x"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.2042-3306.1993.tb02985.x"},{"key":"e_1_2_7_4_2","first-page":"629","article-title":"Volvulus of the large colon in the horse","volume":"177","author":"Barclay W","year":"1980","journal-title":"JAVMA"},{"key":"e_1_2_7_5_2","first-page":"757","article-title":"Strangulating volvulus of the ascending colon in horses","volume":"195","author":"Snyder J","year":"1989","journal-title":"JAVMA"},{"key":"e_1_2_7_6_2","unstructured":"MeagherD.
