Syndrome de l'intestin irritable: un diagnostic d'exclusion. [Irritable bowel syndrome: an exclusion diagnosis?].

The irritable bowel syndrome has been considered a diagnosis of exclusion and multiple diagnostic procedures were often performed in order to exclude an organic disorder. Nowadays, studies show that in young patients, who match the clinical criteria of irritable bowel syndrome and show no alarm features, the prevalence of underlying organic disorders is low, or at least not higher than in the general population. Based on these findings, current recommendations suggest that no extra diagnostic tests have to be performed in those patients, apart from the serological tests in search of celiac disease, which are recommended for patients presenting an irritable bowel syndrome with diarrhea or a mixed-type irritable bowel syndrome.
