Plain-English summary

A 7-year-old Thoroughbred mare had surgery to find out what was causing her colic, which is a type of belly pain in horses. During the surgery, the vets discovered that part of her large intestine was stuck in a small opening called the epiploic foramen, making it impossible to fix without surgery. To help, they cut a part of the intestine called the pelvic flexure and rearranged the intestines to create more space, allowing them to fix the affected areas. After removing the damaged parts of the intestines, they stitched everything back together. The surgery was successful in treating her condition.

Abstract

A 7-year-old Thoroughbred mare underwent exploratory celiotomy for diagnosis and treatment of colic. An irreducible herniation of the large colon through the epiploic foramen was found. To reduce the hernia, the pelvic flexure was transected and the ends of the large colon were closed. The intercolonic mesentery was divided, and unaffected left ventral colon was moved into the epiploic foramen, providing sufficient space so that affected left dorsal colon could be reduced. The affected left ventral colon was then reduced and the diseased portion of both colons was resected. The colons were resected. The colons were rejoined with an end-to-end anastomosis.
