r study, DBE was conducted in 130 patients. Of these patients, 115 had previously undergone CE, which had found potential bleeding site in 63 of these patients and negative results in the other 52 patients. The DBE results showed a bleeding site in two-thirds (41 pts) of the patients who had the same reading by CE, and one-third (16 pts) in the group who had clean CE. DBE was also able to treat all nearly all the bleeding sites found.

Overall, the two procedures were considered moderately effective in detecting sources of intestinal bleeding. Efficacy rates for DBE and CE were comparable in detecting ulcers, blood vessel abnormalities that cause bleeding and large masses, but DBE was more effective in detecting mucosal and submucosal polyps. DBE was also a more lengthy process, averaging 94 minutes, whereas CE averaged 44 minutes. As opposed to CE, DBE did not read the entire small bowel in a single procedure, but it did detect abnormalities in one-third of patients with negative CE results.

"Both procedures offer value to patients with unknown sources of intestinal bleeding or other small bowel problems, and should be used to help evaluate a patient's health," said Shahab Mehdizadeh, M.D., of Cedars-Sinai Medical Center and lead study author. "Clearly, DBE has the advantage of being able to treat problems. But we believe that based on the results of this study, CE should continue to be used as a valuable regular screening test for bowel abnormalities, while DBE will be a better procedure for conformation and treatment of small-bowel problems."
