[Digestive diseases, intestinal infections and intussusception].

There is an improvement in the knowledge of intussusception's pathophysiology. It is due to the development of new rotavirus vaccines, while initially Rotashield was taken off the market because of several cases of intussusception. We report etiopathogenic and epidemiological data, and we describe the diseases associated with an increase risk of intussusception. Intestinal infections (viral or bacterial) are suspected in idiopathic intussusception. Secondary intussusceptions can develop in various intestinal diseases because of intestinal motility abnormalities.
