What Is Colon Torsion In Horses?

Burks, DVM, DABVP. Large colon torsion is a rotation of the colon on its axis. The colon is not tethered to the body wall in any fashion, with the only mesentery connecting the dorsal and ventral colons. Its blood supply is from the cranial mesenteric artery, which supplies 80-90% of the equine intestinal tract.

What causes colon torsion in horses?

Twisting of the colon may be initiated by presence of impacted material or excessive intraluminal gas, or newly created space in the abdomen (such as the case post-foaling). Torsion may occur in either hypomotile or hypermotile states. Torsion may be clockwise (more common) or anticlockwise.

What is colon torsion?

The term cecocolic refers to the cecum and the ascending colon. Torsion is the twisting of the bowel, which may produce the obstruction and strangulation of the involved loop of bowel.

What are the signs of a twisted gut in horses?

The pain often originates from the intestine but it can come from other abdominal organs such as the liver or ovaries. Typical signs are pawing with front legs, kicking up with back legs, turning to look at the flanks, lying down, rolling, and sweating.

How do horses get torsion?

Causes of Twisted Gut
A gassy intestine, whether from diet, parasites or obstruction, can cause the intestine to raise in the abdomen and twist on itself. Certain tumors in the abdomen may be connected to the intestines and other structures in the abdomen, over time causing pressure and creating torsion.

Can a twisted colon fix itself?

A Word From Verywell
Cecal volvulus is an uncommon cause of bowel obstruction that most often occurs in adults. Cases of cecal volvulus can be recurrent (come and go) and resolve spontaneously on their own, but they may also be or become acute and lead to a partial or complete bowel obstruction.

Can a twisted colon be fixed?

If the obstruction is caused by a twisting of the sigmoid area of the large intestine, a doctor may try to straighten out the twisting segment with lighted instruments (such as a proctoscope or sigmoidoscope) or a barium enema. But surgery is sometimes needed to fix twisting of the intestine.

How serious is a twisted colon?

The twisting causes bowel obstructions that may cut off the blood supply to areas of the bowels. A volvulus is a medical emergency that needs surgical treatment. If left untreated, the parts of the bowels that are not receiving enough blood will start to die.

Can a horse poop with a twisted gut?

My regular vet examined my horse but couldn’t tell if his intestines had twisted — something much more serious than colic. A horse’s gut can twist if he rolls enough during colic. If it twists 180 degrees, it’s possible to empty the colon and it’ll usually fall back into place.

How do you treat a twisted gut in a horse?

A twisted intestine requires immediate surgery to reposition the intestine and remove any portion of the intestine that is damaged due to restricted blood flow. In addition, both the small and large intestine can become displaced in the abdominal cavity causing both pain and restricted blood flow.

How do you prevent a twisted gut in horses?

Reduce the risk of large colon torsion by:
Providing regular, quality dental care. Avoiding feeding sugar beet. Minimising the number of horses on a premises, or managing horses in smaller groups. Avoiding sudden changes in the amount of hay or haylage a horse is fed.

Is bloat and torsion the same thing?

Bloat, also known as gastric torsion, and also as gastric dilation volvulus (GDV) syndrome, is a life-threatening disorder that happens when a dog’s stomach fills with gas and becomes twisted. It mainly occurs in deep-chested breeds.

How long can horses live with colic?

The overall survival rate for colic horses over the 10-year study period was 68% (SE: 1.2%; CI: 66–71%; 1087/1588). In the medical group, 1093 horses, short-term survival was 87% (SE: 1.0%; CI: 85–89%; 946/1093).

What is the difference between torsion and volvulus?

Intestinal torsion describes the twisting of the bowel on its longitudinal axis, causing luminal obstruction, whilst intestinal volvulus describes a rotation about the mesenteric axis. Both may occur concurrently.

What helps a twisted colon?

If volvulus is found, the doctor may use the sigmoidoscope to untwist the colon. However, if the colon is twisted tightly or if the blood flow has been cut off, immediate surgery will be needed. Surgery involves restoring the blood supply, if possible, to the affected part of the sigmoid colon.

Is twisted intestine fatal?

Twisted intestines may become blocked (obstructed) or may become injured when the twisting cuts off the intestine’s blood supply. If the blood supply is cut off for a prolonged period, some or all of the intestine may die, which can be fatal.

Is a twisted bowel painful?

Symptoms of a bowel obstruction or a small bowel obstruction
Bowel obstruction symptoms of a bowel obstruction can be painful and distressing. You may experience the following symptoms: Severe abdominal pain, cramps and bloating. Decreased appetite or inability to eat.

What are the signs of a twisted colon?

Symptoms

• Crampy abdominal pain that comes and goes.
• Loss of appetite.
• Constipation.
• Vomiting.
• Inability to have a bowel movement or pass gas.
• Swelling of the abdomen.

Do twisted bowels always need surgery?

If volvulus is found, the doctor may use the sigmoidoscope to untwist the colon. However, if the colon is twisted tightly or if the blood flow has been cut off, immediate surgery will be needed. Surgery involves restoring the blood supply, if possible, to the affected part of the sigmoid colon.

Can stress cause twisted bowel?

Psychological stress is known to cause bowel dysfunction. Psychological stress-associated gastrointestinal symptoms include, but are not limited to nausea, vomiting, abdominal pain and alteration in bowel habits [1].

Can a horse live with a displaced colon?

Horses with strangulating large colon volvulus have been reported to have a relatively low rate of survival[13]. However, another study reported a survival rate of 83%, which is likely due to early recognition and surgical correction of the strangulating volvulus[11].
