[Clinical aspects and diagnosis of jejunal diverticulosis].

Jejunal diverticulosis consists of multiple acquired jejunal herniations of the mucosa and submucosa with an incidence of 1.3 to 2.3%. Clinical symptoms are rare. Numerous and large diverticulae, however, can cause severe abdominal complaints. Etiologically factors always consist of a motility disorder with bacterial overgrowth and rise of intraluminal pressure. An enteroclysis helps to determine the diagnosis. Plain x-rays and a CT of the abdomen are other helpful radiological tools.
