title: Adult intussusception.
abstract: Intussusception occurs when one segment of bowel telescopes into an adjacent segment, resulting in obstruction and possible ischemic injury. The disorder is rare in adults. Most cases of adult intussusception have a demonstrable lead point. Benign and malignant tumors are the cause of intussusception in nearly two-thirds of adult cases. The diagnosis is often elusive because of the vague, chronic nature of the clinical presentation. Symptoms are usually suggestive of intermittent, partial intestinal obstruction. Barium studies or computed tomographic scans can be helpful in making the diagnosis. Surgery is required because of the high incidence of underlying pathology.
