A novel maneuver for colonic polypectomy at the 6-o'clock position.

For effective colonic polypectomy, the polyp has to be positioned in the 5 ± 7− o clock position in the field of view. This has traditionally been achieved by chan− ging the patient s position or by twisting the shaft of the scope, or both [1]. How− ever, rotating a heavily sedated patient is not easy, and twisting the scope exerts a force on the shaft, the position of which has to be maintained by continually ap− plying torque.
