Mesenteric Volvulus in a Bennett's Wallaby (notamacropus Rufogriseus)

Abstract A 2-year-old pet Bennett's wallaby was presented for decreased appetite and constipation of a week's duration. Initial radiographs showed no evidence of obstruction and the wallaby was managed medically for potential gastrointestinal stasis. The wallaby did not improve with medical management and began to regurgitate. Repeat radiographs, abdominal ultrasound and abdominal effusion analysis lead to a clinical suspicion of upper gastrointestinal obstruction. A mesenteric volvulus extending from the mid duodenum to the distal jejunum was found during exploratory laparotomy. Mesenteric volvulus has been previously reported in macropod species but not in Bennett's wallabies.
