Patients and methods
Between September 2000 and March 2004, 178 enteroscopies, including 89 anterograde and 89 retrograde procedures, were performed on 123 patients in Jichi Medical School Hospital, Japan, using the Fujinon double-balloon endoscopy system (Fuji Photo Optical Co., Ltd., Saitama, Japan). In some patients, more than 1 enteroscopy was performed for endoscopic treatment of small-intestinal lesions or endoscopic assessment after the treatment. Double-balloon endoscopy was approved by the ethics committee
Success rates of inserting the double-balloon endoscope in the small intestine
The rates of successful insertion of the double-balloon endoscope into the small intestine by the anterograde approach and the retrograde approach were assessed separately. Insertion beyond the ligament of Treitz and endoscopic observation of the jejunum was achieved by the double-balloon method in all 89 anterograde insertion procedures, and the maximum depth of insertion was beyond the ileocecal valve into the ascending colon in 2 cases. The average depth of insertion estimated from the
Discussion
The need for endoscopic examination of the small intestine has been well established, and the advent of capsule endoscopy is undoubtedly a significant breakthrough for visual diagnosis of the small intestine because it enables easy access to the entire small intestine.9, 10 In addition, we have established a new method of enteroscopy, the double-balloon method, that also allows direct access to the entire small intestine; the clinical value of this new method was evaluated in this study. The
