Small bowel active inflammatory skip segments with strictures in the distal ileum in keeping with the patient's known Crohn disease.  

Strictures in patients with Crohn are defined as small bowel segments that show luminal narrowing with associated proximal/upstream bowel dilation (over 3 cm in caliber). The dilation can be graded as mild (3-4 cm) or severe (>4 cm).

In cases like this one, when strictures are associated with active inflammatory changes, conservative medical treatment is the first option.
