Endoscopic Full-Thickness Resection of a Colonic Lateral Spreading Tumor
Abstract:
The Full-Thickness Resection Device (FTRD; Ovesco Endoscopy, Tübingen, Germany) combines endoscopic full-thickness resection (EFTR) of gastrointestinal lesions with closure and cutting of the tissue in one integrated procedure. It provides en-bloc resection with an integral wall specimen for histopathological evaluation. This resection technique is partially filling of the gaps between the current procedures of choice in endoscopy (endoscopic mucosal resection and endoscopic submucosal dissection) and surgery. We present the case of an EFTR procedure performed for a periappendicular lateral spreading tumor.
