Cholangiohepatitis and cholecystitis associated with biliary peritonitis in a dog - case report

ABSTRACT Cholangitis is a disorder of the bile ducts characterized by inflammation and cholestasis, while cholecystitis is inflammation of the gallbladder. Both conditions cause non-specific signs such as vomiting, abdominal pain, weight loss, anorexia, as well as fever and jaundice in some cases. The aim of this article is to report the case of a five-year-old male canine patient who presented with cholangiohepatitis and cholecystitis associated with biliary peritonitis. On ultrasound, it was possible to identify grade 4/6 biliary sludge, heterogeneity of the liver parenchyma associated with mesenteric inflammation and abdominal effusion. In view of the urgent clinical situation, the patient was referred for cholecystectomy and liver biopsy. In addition, during the procedure, maneuvers were performed to correct abdominal hemorrhagic foci. The histopathological evaluation revealed necrotic hepatopathy associated with mixed chronic-active cholangiohepatitis and cholecystitis. The patient remained stable and showed no clinical signs after the surgical procedure.
