Surgical treatment of persistent colic in a horse caused by an anomalous vascularized fibrous band.

This case report documents an unusual case of persistent colic in a horse caused by an anomalous vascularized band of tissue running between the visceral surface of the liver and the mesentery of the large colon at the level of the sternal/diaphragmatic flexures. The horse was presented with a history of exhibiting signs of mild persistent colic that were suspected to be caused by displacement of the large colon. Volvulus of the large colon was identified during exploratory celiotomy. The band of tissue was transected, and the displacement corrected. The horse made an uneventful recovery.
