A mare subjected to laparotomy to treat a large colon volvulus had the large colon transected close to the cecocolic ligament followed by anastomosis using end-to-end technique. Despite intensive care, worsening of the clinical signs occurred during the first 24 hours after surgery including pain, enterogastric reflux and grievance of the endotoxemia symptoms. Euthanasia was performed. During necropsy, no signs of failure of the anastomosis and peritonitis were found but a strangulated segment of jejunum was observed adjacent to the cecocolic fold and compressed by the body of the cecum and the reminiscent rigth ventral colon. This finding was associated with the worsening of the clinical signs during the post-operative period. This report indicates that an adaptation in the large colon resection technique reducing the cecocolic space may be beneficial in avoiding such complication.
