Extrahepatic biliary duct obstruction secondary to duodenal foreign bodies in 2 dogs

摘要

Two dogs, a 5-year-old neutered male boxer dog and a 2-year-old neutered male Australian cattle dog, were evaluated for vomiting and inappétence. Both dogs were icteric on physical examination, and had hyperbilirubinemia, elevated liver enzymes, andinflammatory changes on diagnostic blood analysis. A proximal duodenal obstruction causing extrahepatic biliary duct obstruction (EHBDO) was suspected in both cases after diagnostic imaging was performed. Exploratory laparotomy confirmed duodenal foreignbodies in both cases. This case report defines duodenal foreign body as a differential diagnosis for EHBDO in dogs.
