Diseases of the gallbladder and biliary tree.

Most disorders of the biliary system are associated with increased activity of parenchymal transaminases (alanine aminotransferase, aspartate aminotransferase) and cholestatic enzymes (alkaline phosphatase and gamma glutamyl transferase) with or without hyperbilirubinemia or jaundice. While parenchymal liver disease is most common in the dog, inflammatory disorders involving the small- and medium-sized bile ducts and zone 1 (periportal) hepatocytes predominate in the cat. Historically, the incidence of disorders restricted to the gallbladder is low in both species; however, with routine diagnostic use of abdominal ultrasonography, the incidence of gallbladder mucoceles and cholelithiasis has increased. Extrahepatic bile duct obstruction is a well-recognized syndrome because of its association with pancreatitis and obvious jaundice. Less common disorders of the biliary system include a cadre of diverse conditions, including necroinflammatory processes, cholelithiasis, malformations, neoplasia, and an emerging syndrome of gallblader dysmotility.
