A Case-based Approach to the Feline Patient with vomiting and Increased Liver Enzymes (Part 1: Hepatic Lipidosis)
نویسنده
چکیده
Most of the noninvasive techniques used in evaluating the feline patient with suspected hepatobiliary disease, such as hepatic enzymology, liver function tests, and hepatobiliary imaging are useful in localizing disease to the liver or biliary system, however, they can rarely be used to establish a definitive diagnosis or an accurate prognosis. Invasive techniques are usually required for this purpose. Invasive (laparotomy, laparoscopic, ultrasound guided percutaneous, or blind percutaneous) techniques are necessary to obtain liver tissue for cytologic or histopathologic evaluation. Techniques for biopsy of the liver may require anesthesia, special equipment, and carry the risk of complications. Fine needle aspiration (FNA) can be utilized to obtain liver tissue for cytology. FNA of the liver is a relatively safe procedure that is simple to perform while requiring no special equipment and minimal patient sedation. Together with the rest of the diagnostic evaluation, FNA can be a useful tool in establishing a diagnosis and prognosis in selected patients with hepatobiliary disease. Additionally, it is a non-invasive technique that can be useful in deciding which subset of patients may require biopsy.
