title: [Duodenosigmoidal fistula in a patient with Crohn's disease].
abstract: The development of enteral fistulas - internal and external - is common in Crohn's disease with a frequency of about 45 % in large series of patients. Most internal fistulas arise in the small bowel, but internal large bowel fistulas occur in about one fourth of all patients with fistulas in Crohn's disease. Colonic gastroduodenal fistulas do occur, but are very rare. Of the 35 cases of colonic-duodenal fistulas that we found in the literature, most have been described to involve either a previous ileocolostomy site or the ascending or transverse colon. There are only three cases displaying sigmoidoduodenal fistulas. To these we add a fourth case with this report. A 42-year-old woman presented with upper abdominal pain, loss of appetite and regurgitations with a foul smell as well as abdominal gas complaints. A duodenosigmoidal fistula was diagnosed by local application of contrast and the fistula tract was excised in typical fashion by resection of the colonic fistula and primary closure of the duodenum. The patient experienced a good recovery with relief of symptoms.
