Extrahepatic Biliary Tract Obstruction due to Foreign Body in a Dog

This case report describes a dog with extrahepatic biliary tract obstruction (EHBO) due to foreign body. An 11-year-old spayed female mongrel dog was referred with the complaint of vomiting and lethargy. On physical examination, mucous membranes and skin were yellowish, and abdomen was mildly distended. On ultrasonography, inspissated bile in gall bladder (GB) and distended bile duct were imaged. Because the patient had no response to the medical treatment, the biliary tract was flushed and hair -like material was drawn out through duodenotomy. The dog recovered within 2 weeks without any complication. In conclusion, it suggested that veterinary clinician should consider a foreign body as the cause of EHBO in dogs. (C) 2016 PVJ.
