The Endocuff Vision device (EVD) is a cap that can be mounted to the tip of a standard endoscope. The EVD has small flexible branches on its outside. The branches turn out during withdrawal. By that the branches are getting in contact with colonic wall. This mechanism leads to a more stabilized position of the colonoscope in the bowel. It is hypothesized that resection circumstances may be improved by using an EVD. In addition, stabilizing the scope during resection may result in a reduced time effort. Until now no controlled trials exist investigating the effect of EVD on the time effect during polyp resection. Therefore a randomized controlled trial needed comparing standard polypectomy versus polypectomy using the EVD during routine colonoscopy procedures.
