| [ Summary ] |
The insertion of endoscopes into the distal small intestine has been a goal for endoscopists. We have developed double balloon endoscopy (DBE), which enables endoscopic scrutiny of the entire small intestine with interventional capabilities. The principle of DBE is that by holding the intestinal wall with a balloon attached to the distal end of a soft overtube, the endoscope can be inserted further without intestinal extension.
DBE was originally developed for exploration and intervention in the small intestine. It has been shown to be useful for cases where it is difficult to maneuver the colon as well. In Nov. 2005, a new type of DBE (EC-450BI5) was released by the Fujinon Corp. It has a 152 cm working length and a 2.8 mm working channel. Using this new type of DBE, we can easily reach to the cecum even in difficult to maneuver colons. We have also applied it endoscopic therapy such as colonic endoscopic submucosal dissection (ESD). In addition to the general uses of DBE in the small intestine, such new applications of DBE and complications experienced, are also described. |
