Abstract
BACKGROUND: Double-balloon enteroscopy (DBE) is a safe and useful procedure for managing small bowel bleeding. However, there are limited studies regarding the preferable timing of DBE and its impact on long-term outcomes. AIM: We aimed to evaluate the association between the timing of DBE and the long-term outcomes of patients suspected of having overt small bowel bleeding who underwent DBE. METHODS: We retrospectively reviewed a prospectively collected database of patients who underwent DBE procedures between May 2004 and April 2016. The electronic medical records were reviewed, and interviews were conducted via mail and telephone. RESULTS: One-hundred sixty-five patients could be followed up. The bleeding source was detected during the initial DBE (DBE-positive group) for 102 patients. Sixty-three patients had no definite lesion during the initial DBE (DBE-negative group). Urgent DBE (DBE within 24 h after the last bleeding episode) was performed more often for the DBE-positive group (50/102; 49.0%) than for the DBE-negative group (10/63; 16.1%) (p < 0.0001). Nine patients in the DBE-positive group underwent curative surgery after diagnosis. Among the remaining DBE-positive patients, 38 of 93 (40.9%) had recurrent bleeding during 2675 days of follow-up. Twenty-one of 63 patients (33.3%) in the DBE-negative group had recurrent bleeding during 2490 days of follow-up. There was no significant difference between the two groups in terms of intervals without rebleeding (p = 0.17). CONCLUSION: Urgent DBE at the initial bleeding episode was useful for detecting lesions. However, the rebleeding rate was not dependent on the initial DBE results.
