Typical Signalment
- Most common in dog:
- German Shepherd Dogs
- Rough Collie
- Occurs occasionally in other species including calves with pancreatic hypoplasia and in cats (chronic pancreatitis)
- In contrast, horses with very little pancreatic tissue develop hypoinsulinism but rarely EPI
Description
Exocrine pancreatic insufficiency (EPI) is a syndrome caused by insufficient synthesis and secretion of digestive enzymes by the exocrine portion of the pancreas
- Leading to insufficient activity of digestive enzymes in the lumen of the small intestine
- Pancreas has considerable functional reserve, large proportion needs to be non-functional to show signs of EPI
- In dog it is mostly caused by pancreatic atrophy or Pancreatic Acinar Atrophy (PAA)
- In the cat it is usually associated with chronic pancreatitis
Diagnosis
History
- Weight loss with or without polyphagia (usually ravenous with scavenging)
- Coprophagia and pica
- Polyuria and polydipsia due to Diabetes Mellitus
- Varible diarrhoea (large volumes of semi-formed faeces)
- Vomiting
- Borborygmus and flatulance
Clinical Signs
- Steatorrhoea
- Diarrhoea
- Mild to marked weight loss
- Muscle wastage
- Polyphagia
- Poor haircoat
- Flatulance
Laboratory Tests
Treatment
Enzyme replacement
Dietary modification
Vitamin supplementation
