Enterovesical fistulas in crohn disease

Abstract

Fistulous communication between the intestinal tract and the bladder is uncommon in Crohn disease. Only 2 per cent of patients afflicted with this disease present with bladder symptoms. Five patients with a mean age of thirty years presented with a prolonged history of bowel disease but a short history of urinary symptoms. Only three patients presented with pneumaturia and fecaluria. None of the fistulas could be demonstrated radiographically. Cystoscopy disclosed the fistulous site as well as acute and chronic inflammation of the bladder. Small-bowel resection with excision of the fistula, partial bladder resection, and diverting ileostomy were performed as a first stage. Ileostomy closure was done two to four weeks later.
