Intussusception, Intestinal Volvulus, Hemorrhagic Bowel Syndrome in Cattle Flashcards
What fluids do you want to use if there is a metabolic acidosis?
LRS or 5% HCO3
Lactate is transformed to HCO3- in the liver
What two species are most prone to developing adhesions?
humans and equines
Try to minimize manipulation of the bowels!
After repairing intussusception, what are the most common post-op complications?
ileus, peritonitis
What is the post-op survival rate for an intussusception in cattle?
43%
What fluids do you want do use if there is a metabolic alkalosis?
LRS or NaCl
T/F: With medical and surgical intervention of hemorrhagic bowel syndrome in cattle, the prognosis is good
False
Even with medical and surgical intervention, the prognosis is poor (70% death rate)
Identify the intussusceptum:
Most likely diagnosis?
perforated abomasal ulcer
What surgical approach is typically used to resect an intussusception in ruminants?
Right flank celiotomy
What do you expect to see on abdominocentesis with an intussusception?
Normal
Because the necrotic segment is contained inside the normal segment
The prognosis for survival in intestinal volvulus depends on:
the duration of the obstruction and the viability of the bowel
What species did this come from?
Cow
Note the increased fat in the mesentery
What is the most likely cause of hemorrhagic bowel syndrome in cattle?
Clostridium perfringens type A
When would you choose to do a side to side intestinal anastamosis?
If you want to create a large lumen or are working on bowel of different diameters
What is/are the most common location(s) for intussusception in horses?
mid-jejunum, ileocecal, cecocolic
Identify the intussuscipiens:
What is the post-op survival rate for a cecocecal or cecocolic intussusception in horses?
27-45%
However, post-op survival rate for a SI intussusception in horses is guarded
Most likely diagnosis?
fat necrosis in mesentery
Fat necrosis in mesentery can end up as obstruction of the SI Usually euthanized because multiple blockages
What does an intussusception look like on ultrasound?
Like this:
What is/are the most common location(s) for intussusception in cattle?
distal jejunum and proximal ileum
What do you find on rectal exam in a cow with intussusception?
- Gas filled loops
- Firm mass
- Tight mesentery
- No feces
- Mucus and clotted blood
T/F: Young animals are more predisposed to intussusception than older animals
True
-
Young are predisposed - more susceptible than old
- If <6mo and have GI obstruction, need to consider intussesception
- Have more enteritis (increase motility), more active
T/F: Hemorrhagic bowel syndrome is an acute enteric disease most frequently seen in beef cattle
False
Hemorrhagic bowel syndrome is an acute enteric disease most frequently seen in dairy cattle
