Contrast enhanced ultrasound (CEUS): A new safe, bedside method of differentiating fibrotic from
inflammatory ileal strictures in Crohn’s Disease
Background:
In patients with Crohn’s disease (CD) complicated by ileal stricture, both acute inflammation and chronic fibrosis
contribute to luminal narrowing and obstruction. The ability to differentiate between reversible inflammation that responds to
medical therapy and a predominantly fibrotic stricture that requires surgical resection holds important clinical implications.
CEUS is a non-invasive, inexpensive, radiation-free and fast modality that provides a functional assessment of ileal strictures.
Methods:
CEUS was performed on 12 pediatric patients with CD complicated by ileal strictures. Contrast enhancement
kinetics of the distal ileum were assessed, including wash-in slope, peak intensity, time to peak intensity and area under the
curve. This quantifiable kinetics reflect the dynamic pattern of blood perfusion in the examined tissue. The same technique was
also applied to healthy jejunal bowel, thus allowing each patient to act as their own internal control.
Results:
CEUS of the distal ileum that revealed a narrowed lumen, thickened submucosa, decreased peristalsis as well as lower
wash-in slope, time to peak, peak intensity and area under the curve as compared to jejunal kinetics would favor a fibrotic
rather than inflammatory obstruction that was further verified at the time of surgery and by histology.
Summary: CEUS is a non-invasive, inexpensive, radiation-free and fast mode of imaging that provides a functional assessment
of ileal strictures in patients with CD that may help guide the medical and surgical management of stricturing small bowel
disease.
