A 6-year old American La Mancha Doe presented for abdominal distention, recumbency, and hypothermia. On presentation, she was obtunded with a severe metabolic alkalosis that was nonresoponsive to fluid supplementation. An abdominal ultrasound examination revealed a distended abomasum. A proximal duodenal or pyloric obstruction was presumed based on sonographic findings and lack of response to medical therapy. An exploratory celiotomy was performed revealing no obstruction of the duodenum or pylorus. Approximately six liters of impacted feed were removed from the abomasum. A diagnosis of idiopathic abomasal impaction was made. The goat recovered with minimal complications, and is reportedly doing well several months after discharge from the hospital. Abomasal impaction is rarely reported in goats. A similar syndrome in Suffolk sheep has been described, but is most often not associated with a successful outcome. This case report describes successful surgical treatment of an abomasal impaction in an adult goat.
