Introduction: The methods described for the study of the small bowel have been of difficult accomplishment and low diagnostic certainty. The Endoscopic Capsule (EC) and Double Balloon Enteroscopy (DBE), can be helpful in the study and treatment of the patient with occult digestive bleeding. Objective: To determine the diagnostic yield of EC and DBE in patients with occult digestive bleeding. Methods and patients: 50 patients with occult digestive bleeding were evaluated, in 24 patients EC was the method of choice and in 26 patients DBE. Findings by means of endoscopic capsule M2A Given Imaging and double balloon enteroscopy were compared. Results: A cause of bleeding was found in 56.52% of patients using EC and in 42, 30% of patients with DBE (p=0,04). Both studies were well tolerated. No adverse effects were reported. Biopsies (n: 1), argon plasma coagulation (n: 7), sclerosis with adrenalin (n: 1) were performed when using DBE. Conclusion: The diagnostic yield of EC and DBE was similar in detecting injuries causing occult bleeding. The advantage of DBE is the possibility of applying therapeutic endoscopic procedures.
