Recent advances and current challenges in endoscopic resection with the full-thickness resection device

Endoscopic full-thickness resection(EFTR)has emerged as a viable technique in the management of mucosal and subepithelial lesions of the gastrointestinal tract(GIT)not amenable to conventional therapeutic approaches.While various devices and techniques have been described for EFTR,a single,combined fullthickness resection and closure device(full-thickness resection device,FTRD system,Ovesco Endoscopy AG,Tuebingen,Germany)has become commercially available in recent years.Initially,the FTRD system was limited to use in the colorectum only.Recently,a modified version of the FTRD has been released for EFTR in the upper GIT as well.This review provides a broad summary of the FTRD,highlighting recent advances and current challenges.
