Liver, Gallbladder, Pancreas (Exam 2) Flashcards
Right vs. Left Displaced Abomasum
Emergent vs. Non-emergent
Right flank vs. L/R flank surgery
Less common vs. Most common
R: emergent, R flank, less common
L: non-emergent, L/R flank, most common
Sign of left displaced abomasum
decreased milk production
2 treatments for displaced abomasum
- gastropexy (sx)
- roll & toggle (left only)
2 types of bloat & treatment (2)
gas + frothy
stomach tube or trocar
Bovine liver is entirely in the (left/right) half of abdominal cavity.
right
Lobes of bovine liver
left lobe (ventral)
right lobe
quadrate lobe
caudate lobe (caudate + papillary process)
Of the caudate lobe (bovine) the papillary process goes towards _____ while the caudate process contacts ____.
portal V
kidney
(T/F) Horses have a gallbladder.
False
In terms of the bovine gallbladder, the ____ duct combines with the ____ duct to form the ______.
cystic duct + hepatic duct = bile duct
What enters the major duodenal papilla (bovine)?
bile duct
Reason for liver biopsy in cattle
fatty liver in postpartum dairy cows
Lobes of equine liver
left lateral lobe
left medial lobe
quadrate lobe
caudate lobe (+ caudate process)
right lobe
Match the following with their lobe of equine liver:
colic impression
gastric impression
Gastric impression: left lateral lobe
Colic impression: right lobe
Which lobes is the round ligament between? (equine)
left medial + quadrate
_____ unite to form the hepatic duct in the horse and distal portion is the _____.
bile ductules
bile duct
______ + _____ unite to form the hepatopancreatic ampulla and open at the (major/minor) duodenal papilla. (equine)
pancreatic duct + bile duct
major
3 vessels supplies liver (equine)
hepatic A
portal V
hepatic Vv
What disorder occurs with high grain ration in cattle? Why?
abscesses
lowers pH in rumen = “sloughing” mucosa so bacteria gets into portal system
Signs of abscesses in ruminants (2)
decreased performance
increased carcass trim
What kind of parasite infection occurs in ruminants if ingested and tunnel through the liver?
liver flukes (trematodes)
In chronic liver disease, adult trematodes are in the ______. (ruminants)
bile ducts
Signs of chronic liver disease (ruminants) (3)
gradual loss of condition
anemia
weakness
Disorder that occurs when >80% liver is destroyed or fibrotic
acute generalized hepatic injury
Main sign seen with acute generalized hepatic injury. Why?
head pressing –> hepatic insufficiency (toxin build up in blood)
Icterus (jaundice) is caused by ______ in horses.
hyperbilirubinemia
Term for “foal jaundice”. What occurs?
neonatal isoerthyrolysis
Mare’s blood type differs from foal –> stimulates reaction
Disease with acute hepatitis associated with administration of equine blood products and leads to liver damage from toxin build up.
Theiler’s Disease
Disorder when portal V doesn’t develop and blood bypasses liver
portosystemic shunt
Which duct(s) enter into the duodenum at the major duodenal papilla? (equine)
pancreatic duct + bile duct
Which duct(s) enter into the duodenum at the minor duodenal papilla? (equine)
accessory pancreatic duct
Term for where portal V passes through equine pancreas
annulus pancreatis
Small ruminants only have a ______ duct which opens at the (major/minor) duodenal papilla.
pancreatic
major
The (ox/horse) has lots of smooth muscle in the spleen while the (ox/horse) and little smooth muscle so the size is restricted.
horse
ox
