Rectal tear with hematoma after accidental breeding as a cause of peritonitis and recurrent colic in a mare.

Received: Revised: Accepted: March 14, 2013 September 20, 2013 January 17, 2014 Rectal tears are relatively common in horses after rectal examinations for diagnosis of gastrointestinal disorders or reproduction. We present the case of a mare that was freely bred and started with colic 8 hrs later. A rectal tear was produced by accidental rectal penetration of the stallion penis with a secondary septic peritonitis. Conservative medical treatment was made. Four days after the accident, the mare presented repetitive colic episodes that were associated with a huge hematoma that almost close the rectum lumen and caused feces retention.
