How is bile duct obstruction determined?
Cats with obstructed bile ducts are usually extremely icteric. In addition to the discoloration in the sclerae and gingivae, their skin is usually an obvious yellow color. “Ultrasound examination is a more accurate non-invasive way to evaluate the gall bladder and bile duct. ” The gall bladder and bile ducts must be examined to confirm the presence of an obstruction. Although this may be possible using radiographs (x-rays), an ultrasound examination is a more accurate non-invasive way to evaluate the gall bladder and bile duct. Exploratory surgery is occasionally necessary to properly evaluate the cat for biliary obstruction.
