Intussusception in adults--report of 3 cases.

Intussusception in the adult is rare. The cases reported here illustrate the usual clinical development of the condition: incomplete, subacute, or chronic subobstruction. Intussusception is usually associated with a localized lesion, mostly a small bowel benign tumor, and a colonic malignant tumor. Diagnosis is effected using barium enema, ultrasonography, or CT scanning. Treatment of intussusception requires surgical intervention.
