Obscure Gastrointestinal Bleeding (Occult or Overt) Clinical Trial
Official title:
Randomized Controlled Trial of Wireless Capsule Endoscopy in the Evaluation of Obscure Gastrointestinal Bleeding
This study compares wireless capsule endoscopy (patients swallow a pill-size camera that
sends pictures of the intestine to a recorder worn on their belt) to an x-ray study (called
dedicated small bowel contrast radiography) in patients who have bleeding from the
gastrointestinal tract without a source of the bleeding identified on routine endoscopic
examinations of the esophagus (food pipe), stomach, small intestine, and large intestine.
The investigators hope to determine if the capsule is a better test in terms of decreasing
further bleeding, decreasing the need for further diagnostic testing, and decreasing the
need for blood transfusions and time spent in the hospital.
