A novel endoscopic technique and device for bimanual rectosigmoidal ESD

Aims Colorectal endoscopic submucosa dissection (ESD) is demanding and associated with a substantial risk of perforation. Key to increasing effectiveness and safety is to apply countertraction during resection. In this study, we present a novel endoscopic device developed to facilitate rectosigmoidal ESD by combination of rigid instruments and flexible endoscopy.
