Recurrent pneumonia and colobronchial fistula from Crohn’s disease: Infliximab alters and simplifies surgical management

Abstract

We report a rare case of right-sided colobronchial fistula in a 47-year-old, severely malnourished male with a history of regional enteritis and recurrent right lower and middle lobe pneumonias medically managed with the addition of the immunomodulator infliximab prior to surgery. On admission, evaluation of sputum cultures and chest radiograph pattern of pneumonia led to the suspicion of colobronchial fistula. This diagnosis was confirmed by abdominal CT enteroclysis. This patient's pneumonia was initially treated with empiric antibiotics, then focused antibiotics based on culture results. The treatment for the regional enteritis and the secondary colobronchial fistula consisted of immunosuppression with infliximab, bowel rest, and total parenteral nutrition. The patient was discharged on a limited course of prednisone and received maintenance therapy with 3mg/kg IV infliximab infusions for four additional treatments with dramatic improvement in his clinical condition. Surgical therapy consisted of only bowel resection; no thoracic surgery or lung resection was necessary. The patient has had a dramatic improvement in his clinical condition and is currently disease-free on no maintenance therapy. The use of TNF-blocking agents such as infliximab may simplify the surgical approach in patients with complicated fistulous Crohn's disease.
