Patients with Crohn’s disease (CD) may require small bowel resections. Unfortunately, some of these patients may develop post-operative small bowel obstructions (SBO). Many clinicians perceive ileal resections dramatically increase the risk of developing SBO in the future, but the incidence and risk factors to developing SBO are poorly described. The primary aim of this study is to document the incidence and factors associated with the development of SBO not related to recurrence of disease in CD patients that undergo ileal resection.
