Abstract
Background and Aims: Endoscopic submucosal dissection is an invaluable technique for resection of gastrointestinal tumors. However, resection of large lesions by means of ESD can be very time consuming. The aim of this study was to evaluate the feasibility of a grasp-and-snare ESD technique using a novel tissue-anchoring device. Material and Methods: In 10 domestic pigs artificial gastric lesions of 2.6-3.4 cm were created using high-frequency electrocautery. Animals were kept under general anaesthesia during the procedures.
