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.

Up to 5% of patients with recurrent gastrointestinal (GI) bleeding remain undiagnosed by EGD and colonoscopy, the presumed source of bleeding in these patients being the small intestine. T...
Capsule endoscopy studies are used for the diagnosis of small bowel mucosal lesions. Since capsule endoscopy depends on the small intestinal peristaltism, the food intake - especially the ...
The purpose of this study is to conduct a cost-effectiveness analysis of wireless capsule endoscopy in the investigation of patients with overt obscure gastrointestinal bleeding. To inform...
The introduction of video capsule endoscopy in 2000 has provided a convenient and minimally invasive imaging method for the whole small bowel. Capsule Endoscopy is used to investigate a nu...
Wireless video capsule endoscopy (VCE) is a non-invasive technology that looks into small intestine and gives images of its lumen as the wireless capsule passes through it. It is used wide...
Small-bowel capsule endoscopy is advocated and repeat upper gastrointestinal (GI) endoscopy should be considered for evaluation of recurrent or refractory iron deficiency anemia (IDA). A new device...
Capsule endoscopy can be used to identify the early stage of small bowel Crohn's disease (CD). We evaluated significant small bowel capsule endoscopy (SBCE) findings that can lead to early diagnosis o...
This prospective, multicenter study evaluated small-bowel capsule endoscopy (CE) for the longitudinal assessment of mucosal inflammation in subjects with Crohn's disease (CD).
An effective bowel cleanse can improve the imaging quality of video capsule endoscopy (VCE). We aimed to further investigate the optimal small bowel cleanse method by comparing the efficacy of 4 L of ...
Non-invasive, endoscopic imaging by use of VIDEO CAPSULE ENDOSCOPES to perform examination of the gastrointestinal tract, especially the small bowel.
Radiography using air, oxygen, or some other gas as a contrast medium.
Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument along either natural body pathways such as the digestive tract, or through keyhole incisions to examine the interior parts of the body. With advances in imaging, endoscope, and miniaturization of endosurgical equipment, surgery can be performed during endoscopy.

Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Barrett’s esophagus is a condition in which the tissue lining the esophagus—the muscular tube that carries food and liquids from the mouth to the stomach—is replaced by tissue that is similar to the intestinal lining. This process is ca...
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism ...
