| [ Summary ] | Endoscopic insertion into the distal small intestine has been a goal for endoscopists. We have developed a new insertion method for enteroscopy, the double balloon method, which enables endoscopic scrutiny of the entire small intestine with interventional capabilities. Double balloon endoscopy uses a flexible overtube with a balloon at its tip to prevent the stretching. The inflated balloon at the tip of the overtube anchors the intestine in place. Being anchored by the balloon, the intestinal tract does not stretch even where there are bends or loops. Consequently, insertion of the endoscope shaft does not stretch the intestine, and the force is effectively transmitted to the endoscope tip. Thus, the endoscope can be advanced into the deep portion of the small intestine. Details of the principles and techniques for insertion of the double balloon endoscopy are described in this report. |
