Inguinal enterocutaneous fistula in a dog.

A two-year-old Jack Russell terrier presented with a chronic history of weight loss and the recent development of a discharging wound in the left inguinal region that was confirmed by ultrasound and contrast radiography to be an enterocutaneous fistula. One day following admission the dog displayed signs of abdominal pain and the general condition deteriorated. At exploratory coeliotomy there was evidence of septic peritonitis and a segment of jejunum was found firmly adhered to the left inguinal canal. The affected jejunal segment was excised and an end-to-end anastomosis performed. A penrose drain was placed in the inguinal wound which was subsequently managed with open drainage. The inguinal wound healed successfully by second intention and the dog returned to normal body condition. The left testis became atrophic and castration was performed several weeks later. To the authors' knowledge this is the first veterinary case report of an inguinal enterocutaneous fistula.
