Small intestinal disorders

Question 1

Difference between canine and feline bile and pancreatic ducts.

Answer 1

Canine bile duct opens separately from the pancreatic duct into the duodenum at the major duodenal papilla.

Dogs generally have two pancreatic ducts, the Accessory pancreatic duct which opens at the minor duodenal papilla & the plain Pancreatic duct which joins the bile duct before entering the major duodenal papilla. The accessory pancreatic duct is the dominant duct in most dogs.

In cats, The common bile duct is shorter than in dogs and always joins with the pancreatic duct before entering the duodenum and empties at the major duodenal papilla.

This is why cats tend to get triaditis. Liver-pancreas-small intestine are connected in cats.
