| Abstract |
Background/Aims
The most frequent indication of double balloon endoscopy (DBE) is obscure gastrointestinal bleeding (OGIB). The aim of the study was to evaluate the clinical factors predicting the detection of bleeding focus by DBE in patients with overt OGIB. Methods: Twenty eight patients (male：female=16：12, 13-82 years) with overt OGIB who underwent DBE were enrolled. Medical records were reviewed and analyzed. Results: Bleeding focus was found in 21 patients (75.0%). Age, gender, time interval between the last blood passage and DBE, transfusion amount, hemodynamic instability, and the number of past bleeding episodes were not different between patients whose bleeding focus was found by DBE and those whose bleeding focus was not found. Duration of bleeding was significantly longer in patients whose bleeding focus was found by DBE than those whose bleeding focus was not found (196.8⁑238.5 vs. 15.5⁑13.7 days, p=0.04). Conclusions: Duration of bleeding may be a useful clinical parameter which predicts the detection of bleeding focus by DBE in overt OGIB. (Intestinal Research 2006;4:95-100) |
