The value of wireless capsule endoscopy in patients with complicated celiac disease

Abstract

Background: Celiac disease may be complicated by symptoms that raise the suspicion of small-intestinal malignancy. The objective is to evaluate wireless capsule endoscopy (WCE) in complicated celiac disease.

Methods: This is a prospective study at a university referral center. There were 47 patients. The indications for WCE were abdominal pain (57%), cancer surveillance (23%), blood in the stool, or persistent iron deficiency (19%).

Results: Findings were consistent with celiac disease in 87%: atrophy (68%), fissuring (62%), and mosaic pattern (19%), extending to the ileum in 34%. Unexpected findings were ulceration in 45% (n = 21), cancer (1), polyps (1), stricture (1), submucosal mass (1), ulcerated nodular mucosa (2), and intussusception (1) were seen in 60%.

Conclusions: WCE has a high yield in complicated celiac disease, by identifying mucosal abnormalities and by excluding adenocarcinoma.
