[Enterocutaneous fistula formation in a dog as a result of colonic foreign body perforation].

A 5-year-old female Poodle was presented with a 3-month history of recurrent abscess and fistula formation on the right abdominal wall. Radiographic and ultrasonographic examinations demonstrated an enterocutaneous fistula formation secondary to foreign body perforation of the colon. Additionally, the diagnosis of a pyometra was made. Twenty-four hours after surgical therapy (ventral midline coeliotomy, foreign body removal, closure of the colon perforation, abdominal lavage and drainage, revision of the fistula) the patient was euthanized due to sepsis and incipient multiorgan dysfunction.
