Background and study aims Endoscopic submucosal dissection (ESD) requires advanced skills to perform safely without complications. The current study evaluated the usefulness of a novel three-dimensional (3D) imaging system in ESD using porcine stomachs. Methods Four endoscopists (two trainees and two experts) performed eight ESD procedures using both 3D and 2D images. https://www.roneverhart.com/2018-NISSAN-SENTRA-Windshield-Wiper-Arm-with-Blade-Frameless-Pair-Left-and-Right/
