Kiko 3yo DSH 4.2011- Unclassified cardiomyopathy, heart
failure ITP-Severe thrombocytopenia with ecchymosis/pechteciation/subdermal hemorrhage Regenerative anemia Hyperglobulinemia Elevated liver/cholestatic enzymes: ALT, ALP, GGT Bilirubinemia Low BUN▪ AUS- dilated hepatic veins, suspect congestion▪ Moderate pleural effusion

Represented 7.5.11- Elevated liver/cholestatic enzymes: ALT, ALP, GGT,at rDVM- resolved on presentation. Focal AUS- choledocholithiasis, liver
aspirates normal 11.10.11- 5 days of intermittent
anorexia, Bloodwork unremarkable Ultrasound▪ Choledocholithiasis▪ Chronic pancreatitis

Cholelithiasis is uncommon in all species except humans
Often incidental Several risk factors in humans, no
definitive risk factors in veterinary patients
Causes malabsorption of vitamin K Deficiencies of Vit K dependent
coagulation factors

Cholesterol stones▪ Pure cholesterol or mixed with material▪ protein, bilirubin, bile salts and inorganic material
▪ High rates of cholesterol secretion with low rates of bile acid secretion▪ Cholesterol precipitates around other particles▪ Salts, sloughed gall bladder mucosal cells, bacteria, bilirubin,
parasite fragments and ova▪ Humans- obesity, high caloric diets, malabsorption of bile acids, estrogens, age,
pregnancy, diabetes, high fat diets, N. European or N. or S. American ancestry Pigment stones▪ Dried and precipitated bilirubin▪ Due to increased uncongugated bilirubin in bile▪ Humans- hemolysis, alchoholic cirrhosis, biliary infection, age, Oriental ancestry

Infection Bacterial nidus Cholangiohepatitis can occur secondarily to damage caused
by bile duct obstruction Associated with pancreatitis and IBD in cats d/t bile duct
and pancreatic duct both opening into papilla▪ Extension of enteric bacteria into biliary tree and pancreas most
likely source of infection Foreign material
ova Hemolysis?
Frequent cause of bilirubin cholelithiasis in humans▪ Liths often 100% bilirubin
Pyruvate kinase deficiency in cats?▪ Abyssinians and Somalians▪ Erythrocytes destroyed due to inability to maintain normal
metabolism▪ Cholelithiasis and EHBO may be sequelae to hemolytic anemia

Ultrasound Mineral?
EHBO- sensitive, though can have false positives▪ 5mm
Cholangiohepatitis or infiltrative disease can appear sonographically normal

Cholangiography
Contrast placed within the gall bladder under ultrasound guidance▪ Bile peritonitis

Retrograde cholangio-pancreatography
•Gold standard for diagnosing pancreaticobiliary disorders in people•Endoscopy and fluoroscopy•Less invasive•Can be used to remove intraluminal structures, place stents, etc.

Cholescintigraphy HIDA scan
hepatobiliary iminodiacetic acid scan Radiopharmaceutical concentrates in bile Can calculate ejection fraction
Fast appropriately to prevent gall bladder contraction Lack of visualization within the gall bladder
implies inflammation- cholecystitis Delayed transit due to obstruction ‘Detection of a suspected bronchobiliary fistula
by hepatobiliary scintigraphy’ biliptysis
