Q

What is proximal enteritis-jejunitis?

A

Inflammation of the proximal part of the jejunum.
*Unknown etiology.

17
Q

How does a horse with proximal enteritis-jejunitis present?

A
  1. Febrile.
  2. Depressed.
  3. Moderate to severe gastric reflux.
18
Q

What is a common sequelae to proximal enteritis-jejunitis?

A

Secondary laminitis.

19
Q

What is the treatment for proximal enteritis-jejunitis?

A

20
Q

What are the large intestinal causes of colic?

A
  1. Left dorsal displacement.
  2. Right dorsal displacement.
  3. Impaction (Large intestine).
  4. Volvulus.
21
Q

How does a left dorsal displacement occur?

A

When the pelvic flexure of the LI gets caught on the nephrosplenic ligament.

22
Q

In what ways can a left dorsal displacement be corrected?

A
  1. Rolling the horse.
  2. Administering phenylephrine to shrink the spleen followed by jogging.
  3. Usually requires surgical resolution.
    *Varying degrees of pain.
23
Q

How does a right dorsal displacement occur?

A

When the pelvic flexure moves to the right side of the abdomen between the cecum and the peritoneum.

24
Q

What does right dorsal displacement result in?

A

Mild to moderate colic pain.

25
Q

What are the treatment options for right dorsal displacement?

A

Medical or surgical management, dependent on the pain level.

26
Q

What is the most common displacement?

A

Right dorsal displacement.

27
Q

What are the primary locations for impactions in the large intestine?

A
  1. Junction of right dorsal colon.
  2. Junction of transverse colon.
  3. Pelvic flexure.
28
Q

What are the signs of a impaction in the large intestine?

A
  1. Acute changes in diameter.
  2. Physical obstruction.
  3. Mild to intermittent colic signs.
29
Q

What are the signs of a impaction in the cecum?

A
  1. Motility issues.
  2. Secondary hospitalization.
  3. Mild to intermittent colic signs.
    *Needs to be closely monitored, due to the risk of rupture.
30
Q

What are the treatment options for an impaction in the large intestine?

A

Usually treated medically, but occasionally surgically

31
Q

What is a volvulus?

A

Longitudinal twist of the colon.
*Usually clockwise.

32
Q

What is the cause of volvulus?

A

Thought to be secondary to gas accumulation in the colon.

33
Q

What results from volvulus?

A
  1. Ischemia.
  2. Severe, unrelenting pain.
34
Q

What group of horses is overrepresented in volvulus cases?
