BACKGROUND Dieulafoy lesions consist of aberrant submucosal arteries, which can cause severe GI bleeding. The predominant location of Dieulafoy lesions is the upper GI tract. OBJECTIVE To our best knowledge, this is the first systematic study on the frequency of bleeding from Dieulafoy lesions in the small bowel and the efficacy of enteroscopic therapy regarding primary hemostasis and long-term follow-up. DESIGN Multicenter, retrospective, observational study. SETTING Nine Austrian centers doing double-balloon enteroscopy or single-balloon enteroscopy. PATIENTS This study involved 284 consecutive patients who were referred for double-balloon enteroscopy or single-balloon enteroscopy because of suspicion of mid-GI bleeding. INTERVENTION A total of 317 double-balloon enteroscopy and 78 single-balloon enteroscopy procedures were performed in 284 patients with suspected mid-GI bleeding. MAIN OUTCOME MEASUREMENTS Demographic, clinical, procedural, and outcome data were collected. RESULTS A Dieulafoy lesion in the small bowel was identified as the source of mid-GI bleeding in 3.5% of patients, with a mean of 1.5 enteroscopy sessions required per diagnosis. In 9 cases the Dieulafoy lesion was found by enteroscopy from an oral approach, and in 1 patient the lesion was found by an anal approach. In all patients primary endoscopic hemostasis was successful. Eight of 10 patients were free from rebleeding episodes (median follow-up 14.5 months, interquartile range 10.0-17.5 months). In 2 of 10 patients, rebleeding occurred, and a surgical intervention was necessary. LIMITATIONS Retrospective study. CONCLUSION Bleeding from Dieulafoy lesions of the small bowel seems to occur more frequently than previously estimated. Most of these lesions are located in the proximal jejunum and can be managed successfully by enteroscopy. After successful endoscopic hemostasis, rebleeding episodes occur in only 20% of patients.
