Purpose
To compare results of capsule endoscopy with those of barium enteroclysis or CT enteroclysis.
Methods
Retrospective review of hospital records revealed 65 patients who had an enteroclysis and small bowel capsule endoscopy. The diagnostic yield of capsule endoscopy was compared with the enteroclysis using Fisher’s exact test.
Results
The main indications were obscure gastrointestinal bleeding (n = 37) and suspected Crohn disease (n = 17). Radiologic studies included CT enteroclysis (n = 30), and fluoroscopic barium enteroclysis with carbon dioxide (n = 18) or with methylcellulose (n = 17). Capsule endoscopy had a higher diagnostic yield (8/17) compared to barium–methylcellulose cellulose enteroclysis (1/17) (P = 0.02). The diagnostic yield of capsule endoscopy was not significantly different compared with barium–carbon dioxide (12/18 vs. 10/18) enteroclysis or with CT enteroclysis (9/30 vs. 8/30). Vascular lesions were better assessed with capsule endoscopy. However, the CT enteroclysis found more lesions in patients with chronic abdominal pain.
Conclusion
Barium–carbon dioxide enteroclysis and CT enteroclysis have similar diagnostic yields for small bowel disease compared to capsule endoscopy. Barium methylcellulose has an inferior diagnostic yield.
