    Abstract:
    BACKGROUND: Double balloon endoscopy (DBE) is a new endoscopic method with the capability for complete observation of whole small bowel. This study evaluated the feasibility and usefulness of DBE for the diagnosis and therapy of small bowel diseases in patients with distorted intestinal anatomy by previous surgeries. PATIENTS AND METHODS: From January 2005 to August 2007, 15 patients with Roux-en-Y anastomosis underwent DBE in Asan Medical Center. Eight were men and the median age was 57 years (range, 40 to 68 y). Indications of DBE were suspected small bowel bleeding, chronic diarrhea, and recurrent acute pancreatitis. The main outcome measurements included completeness of the observation of afferent loop and DBE findings. RESULTS: Because 1 patient underwent DBE twice separately owing to recurrent bleeding, a total of 16 cases were analyzed. The observation of afferent loop was complete in 13 (81%) of 16 cases. The overall diagnostic yield of DBE was 69% (11/16). Out of 11 cases in which DBE detected abnormalities, 6 (55%) showed definite lesions and 5 (45%) probable lesions. Of the 11 cases in which abnormalities were found, 7 (64%) showed lesions in afferent loop. Of the 6 cases in which definite lesions were found, 4 (67%) showed lesions in afferent loop. Therapeutic endoscopic procedures were performed in 4 cases, which include argon plasma coagulation, foreign body removal, and endoscopic nasobiliary drainage. CONCLUSIONS: DBE in patients with distorted intestinal anatomy such as Roux-en-Y anastomosis is a useful tool for the management of small bowel lesions, especially those in the afferent loop.
