Obstrução biliar extra-hepática por colelitíases em felino - relato de caso

Abstract

Obstruction of the extrahepatic bile duct is a syndrome that may be associated with different causes. The most common causes are related to an inflammation of an organ or a combination of involvement of the pancreas, duodenum or biliary tract and cholelithiasis is considered a rare cause of cat obstruction. The clinical manifestations are similar to other hepatopathies that present with cholestasis. Ultrasound examination is considered the best method to differentiate as causes of extrahepatic biliary obstruction. In cases that present any evidence of biliar flow obstruction to the duodenum, treatment consists of colorectal medications and antioxidants to protect the hepatocytes against bile oxidative damage. In obstructive cholelithiasis the surgical intervention is indicated. It is described a case of a feline, SRD, 10 years old and a history of vomiting, anorexia, jaundice, with evolution of one week. The initial clinical suspicion was cholangiohepatitis, but was diagnosed by ultrasonography with extrahepatic biliary obstruction by cholelithiasis. She underwent cholecystectomy.
