Flashcards in Intussusception, Intestinal Volvulus, Hemorrhagic Bowel Syndrome in Cattle Deck (23):
1

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

2

What two species are most prone to developing adhesions?

humans and equines

Try to minimize manipulation of the bowels!

3

After repairing intussusception, what are the most common post-op complications?

ileus, peritonitis

4

What is the post-op survival rate for an intussusception in cattle?

43%

5

What fluids do you want do use if there is a metabolic alkalosis?

LRS or NaCl

6

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)

7

Identify the intussusceptum:

8

Most likely diagnosis?

Q image thumb

perforated abomasal ulcer

9

What surgical approach is typically used to resect an intussusception in ruminants?

Right flank celiotomy

10

What do you expect to see on abdominocentesis with an intussusception?

Normal

Because the necrotic segment is contained inside the normal segment

11

The prognosis for survival in intestinal volvulus depends on:

the duration of the obstruction and the viability of the bowel

12

What species did this come from?

Q image thumb

Cow

Note the increased fat in the mesentery

13

What is the most likely cause of hemorrhagic bowel syndrome in cattle?

Clostridium perfringens type A

14

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

15

What is/are the most common location(s) for intussusception in horses?

mid-jejunum, ileocecal, cecocolic

16

Identify the intussuscipiens:

17

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

18

Most likely diagnosis?

Q image thumb

fat necrosis in mesentery

Fat necrosis in mesentery can end up as obstruction of the SI Usually euthanized because multiple blockages

19

What does an intussusception look like on ultrasound?

Like this:

20

What is/are the most common location(s) for intussusception in cattle?

distal jejunum and proximal ileum

21

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

22

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

23

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
