Background and Aims: The endoscopic powered resection (EPR) device (EndoRotor, Interscope Inc, Northbridge, Mass, USA) is a novel nonthermal device that can be used for polyp and tissue removal in the GI tract. Here, we review the EPR device and illustrate its use for resection of scarred or fibrotic lesions in the GI tract. Methods: In this article and accompanying video, we describe the EPR device features, provide step-by-step instructions for device setup, and review case examples in which the EPR device was used for scarred polyp resection. We also review the current literature describing the use of the EPR device for scarred or challenging polyps. Results: Four lesions with scarring or fibrosis were successfully resected with the EPR device, either with the EPR device alone or as an adjunct to conventional resection methods. No adverse events occurred. A follow-up endoscopy was available in 1 case, which demonstrated no endoscopic or histologic evidence of residual or recurrent lesion. Conclusions: The endoscopic powered resection device can be used alone or as an adjunct to facilitate resection of lesions with significant fibrosis or scarring. This device serves as a useful addition to endoscopists’ toolbox in the management of scarred lesions where other modalities might be technically challenging to use.
