A novel approach to managing a challenging form of equine colic could save the lives of many horses and also save horse owners the cost and uncertainty of major surgery, say University of Florida veterinary researchers.

The approach, developed by , a professor of and his team, relies heavily on a surgeon鈥檚 judgment during surgery to assess the viability of strangulated small intestine, an obstruction that impedes blood flow..

If the affected tissue shows improvements in intestinal color and muscle activity after corrective measures, the organ has an excellent chance of recovering function, and costly surgery to remove the intestinal obstruction is avoided, the researchers say.

鈥淚n general, the treatment for small intestinal strangulation isn鈥檛 as successful as for many other forms of colic,鈥� said Freeman, who also is the director of the college鈥檚 Island Whirl Equine Colic Laboratory. 鈥淭he question we always ask is, do we need to remove this piece of intestine or not?鈥�

Freeman and his colleagues concluded that if certain criteria are met, in many cases, the answer would be no.

Their research appeared last fall in the Equine Veterinary Journal and was presented in July at the 11^th annual Equine Colic Research Symposium in Dublin.

The findings are based on a review of data from 35 cases that used the technique involving horses treated at two university veterinary hospitals between 1996 and 2011.

鈥淚 was very interested in this issue, so in each case, I recorded the severity of the small intestinal changes,鈥� Freeman said. 鈥淚 started off with a grading system, which was tweaked and modified along the way.鈥�

Gradually, the team came up with the system UF is using today in equine clinical cases.

鈥淥nce we have established the degree of intestinal injury, we can now say: This is the cutoff. If it鈥檚 worse than this, we will have to remove that part of the intestine, but if it鈥檚 better, we can leave it in place,鈥� Freeman said.

All horses in the study were discharged after recovery, with only a few developing serious but manageable complications. Many horses survived more than10 years, and some survived for up to15 years.

鈥淭hese long-term survival data are very encouraging and might exceed what have been reported previously for this type of colic,鈥� he said. 鈥淭his study shows that in many cases, these horses can do very well with the affected intestine left in place.鈥�

Also collaborating in the research were D.J. Schaeffer, D.V.Sc., Ph.D., from the University of Illinois College of Veterinary Medicine, and Orlaith B. Cleary, M.V.B., a former large animal surgery resident at UF who now practices in Ontario, Canada.
