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.nacrack.com/quick-save-PPSS-Group-Covert-Stab-Body-Armour-limited-save/
