Successful use of a novel dynamic rigidizing overtube in a patient with looping during colonoscopy.

Video 1This video is our description of use of the novel dynamic rigidizing overtube in a challenging colonoscopy case in which looping was causing significant bradycardia and inability to advance the colonoscope to the cecum. The rigidizing overtube, through sequential cycles of its flexible and rigidized state, allowed for easy movement of the colonoscope to the cecum.
