A retrospective review of small intestinal intussusception in 126 cattle in Switzerland.
Background: Intussusception 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.
Methods: We analysed the medical records of 126 cattle with intussusception of the small intestine.
Results: Demeanour 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.
Conclusions: Clinical findings of intussusception in cattle are often non-specific. Ultrasonography may be required to diagnose ileus.
