[Incarcerated umbilical hernia with enterocutaneous fistula in a calf].

A 3-week-old heifer was referred to the clinic for a suspected fistula of the urachus. Clinical examination revealed the calf to be in moderate condition with an umbilical hernia and an enterocutaneous fistula. Although in calves the abomasum is usually involved in the fistula, it became clear at surgery that this calf had a fistula of the small intestine. The treatment and surgical technique used are discussed.
