[Crohn's disease of the duodenum associated with acute acalculous cholecystopathy].

Since the initial description of Crohn's disease (CD) located in the distal ileum, great number of cases has been observed, and we know that this disease can occur in any part of the digestive tube, from mouth to anus. The duodenal involvement is rare and no more than two hundred cases have been observed. A case of Crohn's disease located in the duodenum, with a severe acalculus cholecystitis, without intestinal involvement is presented. Radiological study showed a stenotic process in the first, second and third duodenal portion, later on confirmed by endoscopy. This was confirmed at surgery, when a gastrojejunostomy with truncal vagotomy, cholecystectomy, besides duodenum and liver biopsies were performed. The patient is asymptomatic four years after surgery. It is considered that bile reflux, resulting from involvement of Vater papilla by CD, is responsible factor of the biliary pathology.
