[Chronic inflammatory bowel disease and pulmonary involvement].

Pulmonary manifestations associated with chronic inflammatory bowel diseases (IBDs) are a factor of morbidity and mortality. This respiratory involvement can manifest in various ways (airways, interstitial, etc.) and remains rare, but is probably underestimated. Subclinical respiratory involvement is frequently found in IBD patients. Airway involvement with bronchiectasis is the most frequent respiratory manifestation. Management is based on a multidisciplinary approach (pulmonologist and gastroenterologist) and depends on the etiology.
