Abstract
Background/Aims
Patients with obscure gastrointestinal bleeding are a diagnostic and therapeutic challenge. Double-balloon enteroscopy is the useful method to visualize the entire small bowel. The aim of this study is to evaluate the usefulness of the double-balloon enteroscopy in patients with gastrointestinal bleeding. Methods: Between March 2004 and August 2004, eight patients were referred for obscure gastrointestinal bleeding. Routine gastrointestinal and colonoscopy were not diagnostic in all patients. Results: The double-balloon endoscopy system was used to perform 12 enteroscopies (6 by the antegrade approach and 6 by the retrograde approach). In four patients, whole small bowel was examined. Duration of bleeding ranged from several days to 10 years. The source of bleeding was identified in 6 (75%) of 8 patients. Interestingly, source of bleeding was more found patients with long bleeding duration and with history of multiple transfusion due to low hemoglobin level less than 10 g/dL. In three patients, lesion was within the range of gastrointestinal and colonoscopy. Conclusions: Double-balloon enteroscopy is a useful method in patients with obscure gastrointestinal bleeding. This is preliminary report and further studies are required to reach a conclusion. (Intestinal Research 2004;2:102-106)
