So, the faecal specimen analysis must be conducted although it rarely provides useful information in the evaluation of the dog with suspected hepatobiliary affection. The diffuse hypoechoic hepatic parenchyma and rounded liver margins with hepatomegaly have been documented in acute hepatic failure as varied sonographic findings ranging from normal to diffusely mottled or decreased echogenicity [ 2326 ] Figure However, for identification of specific hepatopathies and thus establishment of definitive diagnosis of primary liver disease, the histopathological examination of the liver biopsy specimens is usually required.
In canines with extrahepatic bile duct obstruction, no evidence of radiopharmaceutical is detected in the gall caninx or intestine.

Dorsal sonogram 2D of liver depicting hypoechoic parenchyma with portal vessel dilatation in one-year-old mixed-breed dog.
Two-dimensional ultrasonographic appearance of liver in sagittal scan depicting hyperechoic parenchyma with rounding of liver lobe surrounded with textured fluid in a 6-year-old male Labrador Retriever affected with infectious peritonitis. Resolution of skin lesions and long-term survival in a dog with superficial necrolytic dermatitis and liver cirrhosis. These tests rely on analysis of paired blood samples to assess the capacity of the liver to clear endogenous bile acids and ammonia or exogenous bromosulphthalein and indocyanine green substances from the circulation [ 2 ].
However, lack of abdominal contrast and insensitivity to detect subtle changes limits the precision of abdominal radiography.

La ascitis en perros – Causas y tratamiento – ExpertoAnimal ; 14 Jul These noncystic cavitary lesions may also result from acquired collections of blood, necrotic fluid, or cellular debris contained within hematomas, nodular hyperplasia, or large neoplastic masses [ 36 ]. Focal nodular hyperplasia lesions have been documented as well defined solid masses having a variable, often greater echogenicity than the normal liver parenchyma, and a central highly echogenic area.
In addition to this, certain antimicrobial drugs ketoconazole and trimethoprim-sulfaantihelminths mebendazole, diethylcarbamazine-oxybendazole, and thiacetarsamideinhalation anesthetics halothane and methoxyfluraneand analgesics acetaminophen, naproxen, phenylbutazone have also been reported to be hepatotoxic in canines [ 89 ].
There is definite change in the appearance of the faeces in hepatobiliary affections.
Portal hypertension is difficult to diagnose with standard ultrasound imaging. Urinalysis findings reveal bilirubinuria and absence of urobilinogen. It is preferred to percutaneous techniques when excess bleeding is expected and to laparotomy when delayed wound healing hypoalbuminaemia is anticipated.

La ascitis en perros – Causas y tratamiento – ExpertoAnimal ; La asditis en perros – Causas y tratamiento. Abdominocentesis Analysis of abdominal effusions is an important component of diagnosis.
Severe diffuse hepatomegaly can be easily demonstrated on lateral radiographic projections as substantial portion of the caudal liver margin projecting beyond the costal arch along with rounding of the caudal liver edges. La ascitis en perros – Causas y tratamiento.
Ascites, defined as the presence of fluid in the perito Stieger SM, Url A. Kanwarand S. Primary hepatic neoplasia has a variable sonographic appearance ranging from a very large, moderately circumscribed, infiltrating mass bulging beyond the normal liver margins with an echogenicity slightly more mixed than normal liver [ 43 ].
Laboratory evaluation of hepatic disease. The minimal invasiveness of the procedure, rapid patient recovery, and diagnostic accuracy make laparoscopy an ideal technique compared with more invasive procedures.
Microhepatica may be appreciated radiographically with chronic biliary obstruction in dog leads to biliary cirrhosis [ 89 ].
The effusion analysed is then classified as transudate, modified transudate, or exudates Figure 3. American Journal of Veterinary Research.
Biochemical evidence of concomitant renal failure may be present in acute hepatic failure as sequel to exposure to hepatotoxins e. The aim of clinicopathological evaluation of hepatobiliary affections is to identify and characterize hepatic damage and dysfunction, identify possible primary causes of secondary liver disease, xscitis causes of icterus, evaluate potential anaesthetic risks, assess prognosis and response to xenobiotics, and monitor response to therapy.
Laboratory Evaluation An inflammatory CBC in acute hepatic failure may suggest acute pancreatitis or underlying infectious disease. Hepatic affections in the dog are associated with varied and often vague clinical signs and thus frequently present a diagnostic challenge to veterinary practitioners.
Papasouliotis K, Dewhurst E. The potential findings in hepatobiliary neoplasia may include a cranial abdominal mass and hepatomegaly with hepatodynia, pallor, jaundice, and cachexia [ 89 ] Figure Presently, laparoscopy is also emerging as a fruitful imaging modality.
Quantitative ultrasonic assessment of liver size in the dog. Ascitic fluid, when present, typically is a transudate or modified transudate [ 1 ].

Invasiveness of hepatocellular carcinoma and cholangiocellular carcinoma with their radiographic appreciation as hepatomegaly has been reported [ 7 ], whereas inflammatory diseases or neoplasia, hepatic venous congestion, fat infiltration, cholestasis, cirrhosis, infiltrative diseases amyloidosis or lipidosisand storage diseases have been described as the potential causes of diffuse hepatomegaly [ 11 ].
It offers tremendous caniba of direct visceral visual inspection of liver and allows its descriptive or photographic documentation.
Hepatomegaly can be radiographically evidenced as increased distance between the stomach and diaphragm or caudal displacement and ventral covering of the right kidney by the liver [ 39 ]. Whilst a bleeding diathesis will be expected if there is a history of gastrointestinal bleeding, an occult tendency should always be suspected, and a clotting profile is mandatory before a liver biopsy is performed [ 3 ].
Cirrhosis is the irreversible end stage of the chronic hepatic injury caused by the infection, hepatotoxins copper and anticonvulsantsimmunologic injury chronic hepatitischronic cholestasis, and hypoxia [ 9 ].
Laparoscopic postprocurement monitoring of liver biopsy site for bleeding in 7-year-old male mixed-breed dog with hepatic nodular hyperplasia. Selection of the best procedure for obtaining a liver biopsy depends on numerous factors including liver size, presence of coagulopathy, any focal or diffuse lesion, presence of biliary tract obstruction, or any other intra-abdominal abnormalities.
Physical examination ascihis may show fever, cranial abdominal discomfort, jaundice, hepatomegaly due to bile engorgement, abdominal distension, and shock. The Veterinary clinics of North America—Small animal practice. Large liver lobes in hepatomegaly in acute hepatic insults often have rounded margins, whereas the normal liver lobes have sharp edges [ 26 ].
