Suspected Gallbladder Torsion in a Juvenile German Shepherd Dog.

Abstract

An 11 mo old intact female German shepherd dog was presented with a 1 day history of vomiting, abdominal pain, and lethargy. A complete gallbladder torsion with secondary bile leakage was diagnosed during exploratory laparotomy. The dog underwent cholecystectomy at the clearly demarcated border of the viable cystic duct and recovered with no complications. Torsion was possible as a result of the complete absence of normal connective tissue attachments to the hepatic fossa, in human medicine called a wandering gallbladder. No other abnormalities were found on complete abdominal exploration. Very few cases describe torsion of the cystic duct as a cause for extrahepatic biliary disease and secondary bile peritonitis in dogs.
