Fistulae between bowel loops (ileoileal, ileocecal, ileosigmoid, enterovesicular, enterocutaneous, cologastric, and coloduodenal) can occur in patients with progressive Crohn disease. Surgical intervention may be required; left untreated, fistulae can cause complications such as unexplained diarrhea, abdominal pain, or abscess formation. Occasionally, medical management with oral metronidazole or ciprofloxacin can be used to treat underlying infections and symptoms until more definitive medical or surgical planning can be established.
