In Europe and North America, most cases of non-infantile intussusception are associated with intestinal neoplasm. At the University College Hospital, Ibadan, Nigeria, the majority of cases of intussusception seen are ileocecocolic and cecocolic types. These are usually not associated with intestinal neoplasm and simple reduction is all that is required.Intussusception occurring in other segments of the intestinal tract is found to be associated with intestinal neoplasm, mesenteric lymphadenopathy, and ascaris worms. The very mobile cecum and ascending colon found in this population may be related to the high incidence of ileocecocolic and cecocolic intussusception.Indications for resection of intussusception include presence of intestinal neoplasm, irreducibility, gangrenous bowel, and chronicity.

Records of dogs that had abdominal ultrasonography and surgical or pathological diagnosis of intestinal intussusception between February 1992 and June 1997 were reviewed retrospectively. Ultrasound images were reviewed with respect to appearance of the intussusception, suspected location, evidence of predisposing cause and concurrent lesions. Ten intussusceptions were found, affecting a variety of breeds. The mean (range) age of affected dogs was 2.5 (0.3 to seven) years (four females and six males) and the reported duration of clinical signs, 48 (one to 150) days. Intussusceptions were jejunojejunal (five dogs), ileocolic (three), caecocolic (one) and colocolic (one). A concentric ring sign was identified ultrasonographically in each dog and anatomical location predicted correctly in five instances. Additional ultrasonographic findings associated with intussusceptions included intestinal neoplasm in two dogs, enlarged abdominal lymph nodes in two, multiple mesenteric cysts in one and intestinal foreign body in a further dog. Thus, ultrasonography enables accurate diagnosis of intestinal intussusception and is a useful method for searching for concurrent or predisposing lesions.

The medical records of seven cats with intestinal intussusception that were diagnosed by abdominal ultrasonography and exploratory laparotomy were reviewed. In transverse ultrasonographic sections the intussusception appeared as a target-like mass consisting of one, two or more hyperechoic and hypoechoic concentric rings surrounding a C-shaped, circular or non-specific shaped hyperechoic centre. Part of the intestine representing the inner intussusceptum, located close to the hyperechoic centre and surrounded by concentric rings, was also detected. In longitudinal sections the intussusception appeared as multiple hyperechoic and hypoechoic parallel lines in four cases and as an ovoid mass in three cases. In one case the ovoid mass had a 'kidney' configuration. Additional ultrasonographic findings associated with intestinal intussusception included an intestinal neoplasm in one cat. The results of the present study demonstrate that the ultrasonographic findings of intestinal intussusception in cats bear some similarities to those described in dogs and humans, are relatively consistent, and facilitate a specific diagnosis.
