Cholestasis and cholelithiasis in a domestic ferret (Mustela putorius furo)
2011
Hall, Brittany A. | Ketz-Riley, Cornelia J.
A 3-year-old female spayed domestic ferret (Mustela putorius furo) was presented for evaluation of severely increased liver enzyme activities noted prior to anesthesia. The ferret showed no clinical signs of liver or gall bladder disease. Serum biochemical profile confirmed elevations in alanine aminotransferase and alkaline phosphatase activity and total bilirubin concentration. Abdominal ultrasound revealed a distended and convoluted common bile duct although no obstruction was seen. Upon exploratory laparotomy, a large amount of sediment was found within the bile duct that appeared to be obstructing it, but no other cause for the obstruction was found. A choledochoduodenostomy was performed, and the ferret recovered uneventfully from surgery. Liver enzyme activities returned to normal by 5 days post-operatively. Biopsy and culture results yielded no definitive cause of the bile duct obstruction. Cholestasis is a rarely reported disease in ferrets and generally has been described in connection with neoplasia or parasitism, neither of which was found in the current case.
