Equine colic: real veterinary case reports
Colic — any sign of abdominal pain in a horse — is the single most common life-threatening equine emergency and the leading cause of death in adult horses worldwide. The term covers everything from a mild gas distension that resolves with a walk to a strangulating obstruction that requires emergency surgery within hours. Classic signs are pawing, flank-watching, rolling, sweating, refusing food, and frequent attempts to lie down or stretch out.
The decision tree the vet works through is consistent: heart rate, gut sounds, gastric reflux on nasogastric tube, rectal exam, and ± abdominocentesis. The crucial early call is medical vs. surgical — strangulating lesions (small-intestinal strangulation by a pedunculated lipoma in older horses; large-colon volvulus in postpartum mares) have a sharply better outcome the earlier surgery happens. "Wait and see" with a deteriorating horse is the most common avoidable cause of death.
What vets typically check for
- Vital signs — heart rate over 60 bpm signals a serious case; over 80 is critical.
- Auscultation of all four quadrants — silent abdomen suggests significant disease.
- Nasogastric intubation — > 2 L of reflux suggests small intestinal obstruction.
- Rectal exam — palpate for distended bowel loops, displacements, masses.
- Abdominocentesis if intra-abdominal disease suspected; serosanguineous fluid = surgical.

- Equine veterinarians' care priorities regarding vaccination, colic, lameness and pre-purchase scenarios.
Equine veterinary journal · 2026 · Netherlands
A study looked at what equine (horse) veterinarians think is most important when caring for horses and satisfying their clients. They found that in situations like colic (a painful digestive issue) and lameness (problems with movement), the quality of care was the top priority. When it came to buying a horse, professionalism was more important than in other situations. Overall,
- Short- and Long-Term Outcomes in Horses Following Laparoscopic Nephrosplenic Space Ablation.
Journal Article · 2026 · Italy
This study looked at 48 horses that had a surgery called laparoscopic nephrosplenic space ablation, which is done to help prevent a common issue where part of the large intestine gets displaced, causing colic. Most of the horses recovered well, with 91.7% going home without complications, although 8.3% did experience colic after the surgery. A year after the surgery, about 83.3
- Evaluation of oxidative stress and antioxidant defense biomarkers in healthy and colic horses: correlation with type of colic and outcome.
Journal of veterinary internal medicine · 2026 · Italy
A group of 61 horses suffering from colic were studied to understand how oxidative stress affects their health and survival. The research found that horses with colic had different levels of certain biomarkers compared to healthy horses. Specifically, higher levels of a biomarker called AREase were linked to better survival rates, while lower levels of total antioxidant capacit
- Iatrogenic cecal perforation after abdominal drain placement on a horse.
The Canadian veterinary journal = La revue veterinaire canadienne · 2025 · France
A 16-year-old French saddlebred horse showed signs of colic and was diagnosed with a serious intestinal issue that required surgery. After initially recovering, the horse developed complications, including severe discharge from the surgical site and signs of infection. An abdominal drain was placed, but it accidentally punctured the cecum, leading to another surgery. Fortunatel
- Return of showjumping horses to sporting activity after colic surgery.
Equine veterinary journal · 2025 · Italy
A group of showjumping horses that had colic surgery were evaluated to see how well they returned to competition afterward. Out of 96 horses that underwent surgery, 78% were able to compete again, and most of them performed at the same or even higher level than before. After two years, about 64% of these horses were still alive and competing. This suggests that many showjumping
- How to perform abdominocentesis and interpret abdominal fluid in equine patients.
Journal of the American Veterinary Medical Association · 2025
This study explains how to safely collect fluid from a horse's abdomen while the animal is standing and sedated. A healthy horse was used to demonstrate the procedure, which involves preparing a small area on the abdomen, applying a local anesthetic, and then using a special needle or cannula to collect the fluid. The collected fluid is tested for various parameters, such as pr
Frequently asked questions
- Should I walk a colicky horse?
- Brief walking can help mild gas colic and prevents the horse from injuring itself rolling — but never delay calling the vet to walk a horse that's clearly painful. Don't force-walk an exhausted horse; let it rest while keeping it safe.
- When does colic need surgery?
- When pain persists despite analgesics, heart rate keeps climbing, there's significant nasogastric reflux, or a rectal exam finds an abnormality consistent with a strangulating lesion. The earlier surgery happens after a strangulating diagnosis, the dramatically better the outcome — survival drops every hour you wait.
- How do I prevent colic?
- Consistent feeding times, gradual feed changes, plenty of turnout, free access to clean water, regular dental care, and an effective parasite control programme based on faecal egg counts. Sudden changes in any of these are the most common avoidable triggers.
