OBJECTIVE: Evaluate the diagnostic and therapeutic utility, safeness, efficacy and complications of double balloon enteroscopy (DBE) METHODS: This prospective, descriptive study of DBE took place between July 2010 and November 2011 at Gastroenterology Service of Hospital Nacional Guillermo Almenara Irigoyen-EsSalud. 33 DBE were performed in 30 patients with a double balloon enteroscope: EN-450T5 Fujinon, under conscious sedation and with previous bowel preparation. All of them signed an informed consent. RESULTS: The mean hemoglobin was 9.16 gr. /dl. 16 patients (53%) had capsule endoscopy previous to the exam. The most frequent indication for DBE was gastrointestinal bleeding of obscure origin. The per-oral route was used in 66.7% of the cases reaching a maximum distance of 206 cm. The mean examination time was 137 minutes. The most frequent finding was vascular ectasia. The diagnostic yield was 57.6% (similar to other published series). The therapeutic usefulness is equal to 45.4%. The therapeutic procedure most used was argon beam plasma (ABP). As published by other authors the exam was well tolerated by all patients with no complications after the procedure CONCLUSIONS: DBE is a secure, useful and efficient technique for the exploration and treatment of small bowel disease, mainly in the cases of gastrointestinal bleeding of unknown origin.
