Surgery of the Exocrine Pancreas Flashcards
Which function is this:
Secreting hormones into the circulation, which is primarily (though not exclusively) associated with the maintenance of normoglycaemia via the production of hormones insulin and glucagon.
Endocrine
Which function is this:
Secreting pancreatic products into the gastrointestinal tract, primarily associated with the digestive process via the production of enzymes like trypsin, amylase and lipase which enter the duodenum via the pancreatic ducts and the duodenal papillae.
Exocrine
Blood supply of R limb?
pancreatic branches of the pancreaticoduodenal arteries
Blood supply of L limb?
splenic artery.
In dogs, pancreatic secretions travel along each lobe in ducts before meeting in a Y-shape, forming the?
Accessory pancreatic duct
the accessory pancreatic duct which continues to the (2)
Duodenum + minor duodenal papilla
There is also a second duct which arises from the ducts in the left and right pancreatic lobes which enters the duodenum with the bile duct at the
Major duodenal papilla
What is usually not present in cat?
ACcessory panc duct
A number of risk factors for the development of pancreatitis in dogs and cats have been proposed, which include: (8)
Trauma to the pancreas
Obesity;
Dietary indiscretion;
Hyperlipidaemia and hyperlipoproteinemia;
Drug administration (in particular corticosteroids);
Obstruction of the pancreatic ducts;
Ischaemia (potentially from hypotension under general anaesthesia or in shock as well as from vascular obstruction);
Genetic predisposition.
Select the statement that you think is true.
If acute pancreatitis is recurrent there is a permanent change to the histopathology of the pancreas.
Vomiting is a typical clinical manifestation of pancreatitis.
Vomiting is a typical clinical manifestation of pancreatitis.
Blood markers to look for with panc? (4)
Amylase
Lipase
TLI
PLI
Other than panc, reasons for elevation is amylase + lipase (4)
GI
Hepatic
Neoplasia
Impaired GFR/renal excretion
T or F
Amylase/lipase are alwyas raised in panc
False
Sensitivty of TLI for panc?
Poor (36%)
What is TLI?
This detects trypsin, trypsinogen and trypsin-inhibitor complexes and these are pancreatic specific molecules.
False positive rate for PLI?
40%
Radiography findings with panc?
subtle changes in some cases with a loss of contrast in the right cranial quadrant being seen in some, but not all, pancreatitis patients
U/S findings of panc?
There can be changes in the echodensity of the pancreas with chronic fibrosis or a hyperechoic mesentery surrounding the pancreas due to inflammation.
