ATH-06 First clinical experience with speedboat Rs2, a new multimodality device for colonic submucosal dissection

IntroductionThe ‘Speedboat-RS2’ (Creo-Medical/Wales/UK) is the first multi-modality device, incorporating bipolar-radiofrequency energy for cutting, microwave energy for coagulation, an integrated needle for submucosal injection, and a rotatable blade with a heat insulated hull.MethodsA prospective database from June 2018 to Jan 2019 was analyzed including 20 consecutive patients (mean age: 69.7±15.18 years, 50% males) with 20 colorectal Lateral Spreading Tumours/LSTs. Two operators performed all colonic endoscopic submucosal dissections/ESDs.ResultsSixteen procedures were performed under conscious sedation and 4 general anaesthesia (Olympus/CF-HQ290ZL/13.2 mm tip diameter). Median lesion size was 4 cm (range 1–9 cm). The LSTs and procedural characteristics are described in table 1.
