Surgical Management of Enterocutaneous Fistula in a Mare

Enterocutaneous fistulas are reported to be sequelae of congenital umbilical hernia or penetrating trauma to the equine patient's abdomen. An enterocutaneous fistula is considered to be the least common clinical presentation in a horse with incarcinated umbilical hernia, and may be life-threatening if not managed timely. This case report describes an enterocutaneous fistula in a mare as a sequela to congenital umblical hernia. The mare had an uneventful recovery after surgical repair and delivered a healthy foal on subsequent follow-up. The report highlights the need to repair congenital umbilical hernias (regardless of the size), if they do not resolve by the age of 6 to 12 months.
