Several dots are used for marking the periphery of the lesion about 5 mm outside the edge of the target lesion. The attendees first use a dual knife to mark the periphery (a). The mucosa outside the markings is first cut with a dual knife after which a circumferential incision is made around the lesion (b). Subsequently, dissection is performed using the insulated-tip (IT-2) knife (c). The Coagrasper is used when visible vessels or bleeding are observed (d). The target lesion is then resected and removed from the model (e) leaving a resected mucosa (f)
