Abstract
BackgroundIntussusception is a form of ileus of the intestines in which an oral intestinal segment slides into the adjacent aboral intestinal segment, causing obstruction of the bowel.MethodsWe analysed the medical records of 126 cattle with intussusception of the small intestine.ResultsDemeanour and appetite were abnormal in 123 cattle. Non‐specific signs of pain occurred in 26.2%, signs of visceral pain in 46.8% and signs of parietal pain in 56.4%. Intestinal motility was decreased or absent in 93.7% of the cattle. The most common findings of transrectal palpation were rumen dilation (37.3%) and dilated small intestines (24.6%). In 96% of the cattle, the rectum was empty or contained little faeces. The principal laboratory findings were hypokalaemia (89.6%), hypocalcaemia (76.5%), base excess (72.9%), hypochloraemia (71.8%), azotaemia (62.1%) and haemoconcentration (61.1%). The main ultrasonographic findings were reduced or absent intestinal motility (98.2%) and dilated small intestines (96.0%). A diagnosis of ileus was made in 87.8% and a diagnosis of ileus attributable to intussusception was made in another 9.8%. Right‐flank laparotomy was carried out in 114 cattle. Fifty‐six (44.4%) cows were discharged.ConclusionsClinical findings of intussusception in cattle are often non‐specific. Ultrasonography may be required to diagnose ileus.
