A novel reusable endoscope (Olympus Corp, Tokyo, Japan) with an integrated motor (Fig. 1A) was developed for rotating a disposable short spiral overtube mounted on the insertion tube portion. The drive motor located in the endoscope handle is activated by foot pedals and controls the direction and speed of rotation of a coupler located in the middle of the endoscope’s insertion tube (Figs. 1B and C). The rotation coupler is the only portion of the endoscope that rotates; the distal and proximal portions of the insertion tube do not rotate.
