OBJECTIVE: Obscure gastrointestinal bleeding from jejunal and ileal lesions remains undiagnosed using traditional imaging techniques (radiologic, endoscopic). This prospective study compares the diagnostic detection rate of small-bowel lesions using wireless video capsule endoscopy (VCE) with the detection rate using double-balloon enteroscopy (DBE) in patients with obscure gastrointestinal bleeding (OGIB). Tolerance, adverse events, endoscopic interventions, and prognosis were described as secondary aims. METHODS: Thirty-five consecutive patients with obscure gastrointestinal bleeding were evaluated (22 males and 13 females; mean age 63.2 yr; range, 19-86 yr). The detection rates of the Given M2A wireless VCE and DBE were compared. RESULTS: Small-bowel abnormalities were detected using VCE in 28 (80%) of the 35 patients with OGIB, compared with 21 (60%) of the 35 patients using DBE (p = 0.01). Both examinations were well tolerated, but VCE was more acceptable to patients. No major adverse event occurred after either examination. Biopsies (n = 27), argon plasma coagulation (n = 19), tattoo injection (n = 8), and polypectomy (n = 2) were feasible with DBE when indicated in 27 of the 35 patients (77%). During a median (range) follow-up period of 5 (2-12) months, 26 (74%) patients remained clinically stable and did not require blood transfusions after DBE procedures. Eighteen (51%) of those who remained clinically stable had received APC therapy. CONCLUSIONS: High detection rates of the causes of OGIB are feasible with VCE and DBE. Although the detection rate of VCE was superior, our results indicate that the procedures are complementary; an initial diagnostic imaging employing VCE might be followed by therapeutic and interventional DBE.
