Case report: Ileo-jejunal entrapment in a uterine mesometrium rent of a non-pregnant mare

Abstract

A ten-year-old, non-pregnant Arabian mare presented with acute uncontrollable abdominal pain. A diagnosis of small bowel compromise was made on clinical and trans-abdominal ultrasonographic examination. Euthanasia was elected by the owner and the necropsy examination revealed herniation and venous infarction of five meters of distal jejunum and the entire ileum within a 7.5 cm rent in the right mesometrium of the uterus. Small bowel entrapment in a mesometrial rent is rare in domestic animals with few case reports in the literature, but interestingly has been relatively well-characterized in primiparous and multiparous women. Entrapment in a mesometrial rent may be considered as a differential diagnosis for acute small bowel compromise and colic in non-pregnant and pregnant mares.
