A spayed female British Shorthair cat aged 1 year and weighing 2.6 kg presented with a 5-day history of vomiting and anorexia. Physical examination revealed icterus, and serum biochemistry showed markedly elevated bilirubin and liver enzyme levels. Abdominal ultrasonography revealed a dilated common bile duct (4 mm), 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 cm 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.
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' knowledge, this is the first peer-reviewed report of feline EHBO caused by extramural duodenal compression that was successfully resolved without biliary tract incision.
一只1岁绝育雌性英国短毛猫，体重2.6千克，出现了5天的呕吐和厌食病史。体格检查发现黄疸，血清生化检查显示胆红素和肝酶水平显著升高。腹部超声检查发现胆总管扩张（4毫米），胆囊壁轻度增厚，十二指肠乳头处有一个圆形高回声异物。增强CT扫描证实十二指肠近端降部有一个1.9厘米的甜甜圈形异物，导致胆总管壁外受压。进行了剖腹探查和肠切开术以取出异物。这只猫恢复顺利，术后48小时内胆汁参数恢复正常，术后第4天临床症状消失。
本病例突出了猫肝外胆管阻塞（EHBO）一种罕见但可通过手术治疗的原因，即十二指肠异物引起管腔外压迫，而无管腔内迁移或黏膜侵犯。它强调了断层成像和及时手术干预对取得良好预后的价值。据作者所知，这是第一份经同行评审的关于猫因十二指肠壁外压迫导致EHBO且未进行胆道切开而成功解决的报告。
