Rare case of extrahepatic biliary obstruction caused by a duodenal foreign body in a cat.
Article in JFMS open reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Case summary: 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. Relevance and novel information: 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.
