In 2010, we performed full-thickness resection (FTR) using the over-the-scope clip (OTSC) system (Ovesco Endoscopy GmbH, Tübingen, Germany) [1]. The key aspects of this technique are to apply the clip to the target lesion and then to resect above the ensnared lesion. However, these maneuvers require several separate accessories. Therefore, a new device to perform FTR was developed. Herein we de...
