Azathioprine is More Effective than Mesalazine at Preventing Recurrent Bowel Obstruction in Patients with Ileocecal Crohn’s Disease

Background Patients with subocclusive Crohn’s disease (CD) who received azathioprine (AZA) therapy had lower re-hospitalization rates due to all causes and for surgical management of CD compared to those treated with mesalazine during a 3-year period. We investigated whether AZA also was effective for prevention of recurrent bowel obstruction.
