Abstract
Single or double balloon enteroscopy is able to visualize the small bowel well but is not readily available due to the cost and procedural expertise required. A novel dynamic rigidizing overtube is now available to assist with difficult colonoscopy. In its flexible state, the overtube material is soft and pliable, but in its rigid state becomes 15 times stiffer when a vacuum is applied. This aids in stability and minimizing loop formation. The aim of this study was to assess feasibility and safety of this novel device for use in performing antegrade and retrograde enteroscopy.
