title: Signalment, history, and outcome of cats with gastrointestinal tract intussusception: 20 cases (1986-2000).
abstract: OBJECTIVE
  To determine signalment, history, and outcome of cats with gastrointestinal tract intussusception and to identify physical examination, diagnostic imaging, surgical, histologic, and necropsy findings in affected cats.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  20 cats with intussusception.
  
  
  METHODS
  Medical records were evaluated for information on signalment; history; physical examination, diagnostic imaging, surgical, histologic, and necropsy findings; and outcome.
  
  
  RESULTS
  Ten cats were < 1 year old, and 9 were >or= 6 years old. Anorexia (14/17), lethargy (12/17), and vomiting (12/17) were the most common reasons for examination. Dehydration (13/18), poor body condition (12/18), signs of abdominal pain (8/18), and an abdominal mass (8/18) were the most common physical examination findings. Abdominal radiography revealed intestinal obstruction in all 10 cats in which it was performed; abdominal ultrasonography revealed intussusception in all 7 cats in which it was performed. The most common intussusception was jejuno-jejunal (8/20), and no intussusceptions were found proximal to the duodenum. Eleven of 13 cats that underwent laparotomy required intestinal resection and anastomosis. Histologic examination revealed intestinal lymphoma or inflammatory bowel disease in 7 of 8 cats >/= 6 years old and idiopathic intussusception in 7 of 8 cats < 1 year old.
  
  
  CONCLUSIONS
  Results suggested that in cats, intussusception has a bimodal age distribution, is most commonly jejuno-jejunal, often requires surgical resection and anastomosis, is often associated with alimentary lymphoma or inflammatory bowel disease in older cats, and is readily diagnosed by means of ultrasonography.
