Ileo-ceco-rectal Intussusception Requiring Intestinal Resection and Anastomosis in a Tawny Eagle (Aquila rapax).

A 23-year-old male tawny eagle (Aquila rapax) was examined because of sudden onset of lethargy, regurgitation, and hematochezia. An intestinal obstruction was suspected based on radiographic findings, and an ileo-ceco-rectal intussusception was confirmed by coelioscopy. A 14.3-cm section of intestine was resected before an intestinal anastomosis was done. Coelomic endoscopic examination confirmed a postsurgical complication of adhesions between the intestinal anastomosis and the dorsal coelomic wall, resulting in a partial luminal stricture and requiring surgical removal of the adhesions. Rectoscopy was useful in diagnosing a mild luminal stricture related to the second surgery. Complete recovery was observed 2 months after surgery. Lack of further complications in the 2 years after surgery demonstrates good tolerance of intestinal resection and anastomosis of a large segment of bowel in an eagle. This report is the first reported case of intussusception in an eagle and emphasizes the potential use of endoscopic examination in the diagnosis as well as in the management of complications.
