This retrospective study describes the findings in 35 cows with ileus caused by CSI (compression of the small intestine) by adhesions, abscesses, and the gravid uterus. Colic occurred in 34.3% of the cows. Rumen motility was reduced or absent in all cows, and intestinal motility was decreased in 85.7%. Ballottement and\/or percussion and simultaneous auscultation were positive on the right side in 73.5% of the cows. The rectum contained little or no faeces in all cows, and transrectal examination revealed dilated small intestine in 25.7% of the cows, but the actual site of compression could not be palpated. The main ultrasonographic findings were reduced or absent intestinal motility and dilated loops of small intestine. Thirty-one of the thirty-five cows underwent right flank laparotomy; fourteen of these were euthanised intraoperatively, and seventeen recovered and were subsequently discharged. CSI is a rare cause of ileus. Improvements in the diagnosis of CSI are needed to prevent unnecessary laparotomy in cows with a grave prognosis.<\/jats:p>","DOI":"10.3390\/ani15040569","type":"journal-article","created":{"date-parts":[[2025,2,17]],"date-time":"2025-02-17T10:26:12Z","timestamp":1739787972000},"page":"569","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Ileus Caused by Compression of the Small Intestine in 35 Cows"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2573-687X","authenticated-orcid":false,"given":"Ueli","family":"Braun","sequence":"first","affiliation":[{"name":"Department of Farm Animals, Vetsuisse Faculty, University of Zurich, 8057 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Gerspach","sequence":"additional","affiliation":[{"name":"Department of Farm Animals, Vetsuisse Faculty, University of Zurich, 8057 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Bennien","sequence":"additional","affiliation":[{"name":"Department of Farm Animals, Vetsuisse Faculty, University of Zurich, 8057 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monika","family":"Hilbe","sequence":"additional","affiliation":[{"name":"Institute of Veterinary Pathology, Vetsuisse Faculty, University of Zurich, 8057 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4607-792X","authenticated-orcid":false,"given":"Karl","family":"Nuss","sequence":"additional","affiliation":[{"name":"Department of Farm Animals, Vetsuisse Faculty, University of Zurich, 8057 Zurich, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,2,16]]},"reference":[{"key":"ref_1","unstructured":"Dirksen, G., Gr\u00fcnder, H.D., and St\u00f6ber, M.
