Fístula enterocutânea em equino - relato de caso.

Abstract

Enterocutaneous fistulas are formed by abnormal communication between the intestinal wall and the skin surface resulting in the passage of fecal content to the outside. Most often, enterocutaneous fistulas result from untreated umbilical hernias, in which only one edge of the intestinal loop is affected, known as Richter's hernia. The mare reported was treated with the presence of an open wound that drained fluid in the abdominal region and a history of a congenital umbilical hernia. A herniorrhaphy was performed using the closed technique and resection of the fistulated tissue. After a few days, the fistula recurred mildly and a second surgery was performed for correction. The muscle tissue was friable and after a few days there was dehiscence of the stitches and evisceration. Emergency surgery was performed to wash and reposition the intestinal loops and a polypropylene mesh to close the abdominal cavity. However, after a few days, the mare died due to probable septic peritonitis. Monitoring umbilical hernias in horses is essential to avoid possible complications such as enterocutaneous fistulas. The lack of reports and descriptions in the literature makes more studies necessary on the topic and forms of management for fistula treatment.
