Double-balloon enteroscopy [DBE] in patients presenting with obscure gastrointestinal bleeding [OGIB]

ABSTRACT

Background and study aims: obscure gastrointestinal bleeding [OGIB] is defined as bleeding of unknown origin that persists or recurs after an initial negative investigation. Identifying the source of OGIB represents a diagnostic challenge that is frequently focused on visualizing the small intestine. Conventional diagnostic methods, such as push enteroscopy, small-bowel follow-through, radionuclide scanning, and angiography, each exhibit inherent limitations. Double balloon enteroscopy [DBE] was designed specifically to evaluate the entire small bowel. DBE allows for better visualization, biopsy of the identified lesions and application of therapeutic techniques. This study sought to assess the role of DBE in the diagnosis and management of patients with OGIB
