Condition

Chronic Pancreatitis

2

Secretion of bile acids provides

Digestion of dietary fats

Excretory route for metabolites and drugs

Buffers to neutralize acid pH from stomach

3

Clinical signs of acute pancreatitis

Severe abdominal pain

Anorexia

Vomiting

Cardiovascular collapse

4

Describe this developmental abnormality of the pancreas

Pancreatic Hypoplasia (Pancreatic Atrophy- Dogs)

5

Anomaly of the gallbladder is a common result of fasting but can also be caused by Lantana camara toxicosis.

Gallbladder distention

6

Pancreatic condition in which calculi are formed within the pancreatic duct due to inflammation.

Pancreatic Lithiasis

Gallbladder Distension

10

Differential diagnosis for gallbladder edema

Right sided heart failure

Infectious Canine Hepatitis

11

Condition of the gallbladder where components of bile are supersaturated and precipitate - typically does not cause a problem unless obstruction occurs.

Gallbladder stones (choleliths)

Cholecystitis

15

Condition

Q image thumb

Acute Pancreatitis

16

Morphological Diagnosis

Q image thumb

Diffuse severe fibrinous cholecystitis

17

Chronic Pancreatitis in horses is often secondary to

Parasitic migration

Ascending bacterial infection

Chronic eosinophilic gastroenteritis

18

Cholangitis, parasites of fibrosis and cholelithiasisi cause this gallbladder condition resulting in post hepatic jandice, hepatic atrophy and biliary fibrosis.

Biliary Obstruction

19

Condition of the gallbladder that is typically of traumatic orgin that results in steady leakage of bile into the peritoneal cavity - chemical peritonitis.

Rupture of the biliary tract or the gallbladder

20

Condition

Q image thumb

Pancreatic Hyperplasia

21

Pancreatic condition characterized by fibrosis, parenchymal atrophy and chronic inflammation usually a result from repeated mild episodes of acute pancreatitis

Chronic Pancreatitis

22

T/F: The exocrine pancreas, like the liver has a large functional reserve.

True

24

Condition

Q image thumb

Metastatic Melanoma of the Pancreas

25

Pancreatic neoplasm that originates from the pancreatic acini and/or ducts and is characterized histologically by thick fibrous connective tissue capsule.

Pancreatic Adenoma

26

Possible differential diagnosis for hemorrhagic cholecystitis

Salmonellosis (Cattle)

Arsenic Toxicosis

27

Condition

Q image thumb

Pancreatic Adenocarcinoma

28

Pancreatic condition due to defect in acinar tissue - the islet cell tissue may be quantitatively and qualitatively normal.

Pancreatic Hyplasia

Called Pancreatic Atrophy in canines

29

Condition

Pancreatic Adenoma

30

What dis?

Q image thumb

Gallbladder carcinoma

31

Condition

Q image thumb

Chronic Pancreatitis

32

Gross appearance of what pancreatic condition - focal areas of grey-white discoloration due to coagulative necrosis, admixed with black areas of hemorrhage and chalky white ares of fat necrosis.

Acute Pancreatitis

33

Incidental finding of the pancreas of old dogs, cats and cattle.  Characterized histologically as having cells of uniform size and shape, non-encapsulated and do not compress the surrounding parenchyma.

Pancreatic Nodular Hyperplasia

34

Pancreatic neoplasm that is typically spherical and circumscribed, involvement of the bile ducts will cause jaundice and invasion of the duodenum.

Pancreatic Adenocarcinoma

35

Pancreatic calculi consist of

Calcium carbonate and Calcium Phosphate

36

Possible differential diagnosis for fibrinous cholecystitis

Acute Salmonellosis

Yersiniosis

37

Choleliths are composed of?

Cholesterol

Bile pigments

Salts of bile acids

Calcium salts

Proteinaceious matrix

38

Condition of the gallbladder that causes cystic proliferation of the mucous producing glads seen in old dogs and may be associated wtih mucocele.

Gallbladder Hyperplasia

39

Histologic appearance of what pancreatic condition - necrosis of parenchyma, interlobular stroma edema and contains fibrin, hemorrhage and inflammatory cells.

Acute Pancreatitis

40

Main function of the exocrine pancreas

Production and secretion of enzymes

41

What dis?

Biliary Obstruction

42

Condition

Q image thumb

Pancreatic Nodular Hyperplasia

43

Starvation and obstruction of the pancreatic ducts can cause what pancreatic change?

Pancreatic Degeneration

44

T/F: The exocrine pancreas, like the liver has a great capacity for regeneration.

False

45

Bile consists of

Water

Cholesterol

Bile Acids

Bilirubin

Inorganic Ions 

46

What dis?

Q image thumb

Gallbladder Edema

47

What dis?

Q image thumb

Gallbladder Mucosal Hyperplasia

48

Pathogenesis of Acute Pancreatitis

  1. Inappropriate in situ activation of pancreatic digestive pro-enzymes
  2. Consequent autodigestion of pancreatic tissue and peri-pancreatic adipose tissue followed by inflammation

49

Incidental finding of the pancreas causes small nodules embedded in the submucosa of the stomach, intestine, gallbladder and in the parenchyma of the liver, spleen and in the mesentery due to dislocation of portions of the duodenal buds during embryonic development.

Ectopic Pancreas

50

Pancreatic change seen in systemic infections due to epitheliotropic viruses or intoxication (mycotoxins, zinc toxicity)

Multifocal Pancreatic Degeneration and Necrosis
