Physical examination revealed icterus, and serum biochemistry showed markedly elevated bilirubin and liver enzyme levels. Abdominal ultrasonography revealed a dilated common bile duct (4\u2009mm), mild gallbladder wall thickening and a round, hyperechoic foreign body located at the major duodenal papilla. A contrast-enhanced CT scan confirmed the presence of a 1.9\u2009cm doughnut-shaped foreign body in the proximal descending duodenum, causing extramural compression of the common bile duct. Exploratory laparotomy and enterotomy were performed to remove the object. The cat recovered uneventfully, with normalisation of biliary parameters within 48 h and resolution of clinical signs by postoperative day 4.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Relevance and novel information<\/jats:title>\n                    <jats:p>This case highlights a rare but surgically treatable cause of extrahepatic biliary obstruction (EHBO) in cats caused by a duodenal foreign body exerting extraluminal compression without intraluminal migration or mucosal invasion. It emphasises the value of cross-sectional imaging and timely surgical intervention in achieving favourable outcomes. To the authors\u2019 knowledge, this is the first peer-reviewed report of feline EHBO caused by extramural duodenal compression that was successfully resolved without biliary tract incision.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/20551169251366439","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T06:35:46Z","timestamp":1757313346000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Rare case of extrahepatic biliary obstruction caused by a duodenal foreign body in a cat"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7169-2006","authenticated-orcid":false,"given":"Hyunwook","family":"Myung","sequence":"first","affiliation":[{"name":"Nel Animal Medical Center, Anyang-si, Republic of Korea"},{"name":"Department of Veterinary Surgery, College of Veterinary Medicine, Konkuk University, Seoul, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilyong","family":"Yun","sequence":"additional","affiliation":[{"name":"Nel Animal Medical Center, Anyang-si, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonghyop","family":"Lee","sequence":"additional","affiliation":[{"name":"Nel Animal Medical Center, Anyang-si, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,9,7]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/1098612X17706465"},{"key":"e_1_3_3_3_2","doi-asserted-by":"crossref","unstructured":"Van den Ingh TSGAM Cullen JM Twedt DC et al.
