[Diverticulosis--diverticulitis].

Diverticular disease is a common disorder in the western world. The course of the illness is benign: At least 75% of all patients with diverticular disease remain asymptomatic life long. 10-20% develop clinical symptoms, usually painful diverticulitis. Diverticular disease is diagnosed clinically in most cases. Computed tomography (CT) has replaced contrast enema as the diagnostic procedure of choice for acute diverticulitis. Most patients with uncomplicated diverticulitis can be treated as outpatients Bowel rest, intravenous fluid therapy, broad spectrum antibiotics are treatment modelities if a patient has been hospitalized. Close follow-up is mandatory, especially in patients treated as outpatients. Failure to improve with conservative medical therapy warrants a diligent search for complications and surgical consultation. Surgery may be nessasary in a few of hospitalized patients. Commonly, the operation is performed in a single-stage procedure. Once the acute setting has passed, a colonoscopy should be electively performed to exclude competing diagnoses particularly colonic cancer.
