Abstract: Sixty two patients with small bowel bleeding underwent double balloon endoscopy (DBE).Clinical features were compared between patients with positive DBE findings (50 cases) and those with negative findings (12 cases).Results revealed that the causes of melena were discovered in 75.0％(21/28) patients via oral approach,while the lesions were found in 81.8％ (18/22) patients with hematochezia via anal approach ( P ＜ 0.01 ). Duration of bleeding was longer and number of bleeding episodes was higher in patients with positive DBE findings than those with negative findings (P ＜ 0.05 or P ＜ 0.01 ).The time interval between the latest bleeding and DBE was significantly shorter in patients with positive DBE findings (P ＜ 0.05).Positive diagnostic rate was significantly higher in patients with three or more bleeding episodes than those less than three times (92.5％ vs.11.1％,P ＜ 0.01 ).DBE performed within seven days or less increased the positive diagnostic rate significantly than that after seven days (97.1％ vs.59.3％,P＜0.01).
