Endoscopic submucosal dissection for a rectal tumor behind a rectal fold with novel two-step utilization of a traction device Colorectal endoscopic submucosal dissection (ESD) can be challenging depending on the location of the lesion [1,2].A tangential endoscopic approach is key to success.Herein, we describe successfully performing ESD for a rectal cancer using a novel means of achieving a tangential endoscopic approach ( Video 1).A 63-year-old man was referred to our hospital for endoscopic treatment of a rectal neoplasm.Colonoscopy revealed a
