Study Supports Preventative Surgery to Reduce Recurring Entrapment Colic 

Horse owners worry over recurring colic is justified 

When a horse suffers nephrosplenic entrapment, a specific type of displacement colic, the risk of it happening again can be elevated. For high-performance horses, that means more than pain and emergency bills; it can disrupt training schedules and competition plans. A preventative surgery called laparoscopic closure of the nephrosplenic space has been widely used for years, but until now, no one knew how long the benefits lasted. Dr. Nicola Cribb, Department of Clinical Studies, Ontario Veterinary College (OVC), discusses new research from a five-year study at the OVC.

What is nephrosplenic entrapment colic?

Nephrosplenic entrapment colic is a condition where a section of the large intestine, usually the large colon, moves into the natural gap between the spleen and the left kidney. That gap is called the nephrosplenic space. Some horses can have a deeper or wider space, and if an excess of gas builds up in the large colon, it can cause displacement and the colon may slip into this trough and become trapped. 

The result can be painful abdominal distension, gas accumulation, and obstruction of normal gut movement as well as enlargement of the spleen. If untreated, the condition can become life-threatening.
