Double balloon endoscopy in two hundred fifty cases for the diagnosis and treatment of small intestinal disorders

Abstract.

Double balloon endoscopy is based on a new insertion mode in which two balloons at the distal ends of both an endoscope and an overtube are operated in combination. We have performed 419 enteroscopic examinations in 250 patients using the Fujinon double balloon endoscopy system between September 2000 and October 2005. Total enteroscopy was successfully achieved by the combination of both oral and anal approaches in 55 out of 71 cases in whom total enteroscopy was intended. Of 250 patients, ulcerative and/or erosive lesions were found in 49 cases and tumors/polyps were found in 49 cases. We also found 26 cases of vascular lesion, including angiodysplasia. Endoscopic treatments, including hemostasis using either clipping devices or electro coagulation, polypectomy, endoscopic mucosal resection, balloon dilation, and stent placement was successfully carried out. Double balloon enteroscopy is both feasible and useful technique for the diagnosis as well as treatment of small intestinal disorders.
