N2 - Background and Objectives: EUS training is recognized to have a substantial learning curve. To date, few dedicated training programs for EUS have been described. The swine model has been highlighted as a realistic tool to enhance EUS training. Studies extensively describing EUS swine anatomy are lacking in the current literature. The article aims to describe both radial and linear EUS pancreatobiliary swine anatomy. Materials and Methods: Four live pigs were endoscoped under general anesthesia using both radial and linear array echoendoscopes. Relevant images and videos were recorded. Results: It was possible to effectively image aorta, crus of the diaphragm, celiac trunk, superior mesenteric artery, pancreas, common bile duct, gallbladder, portal vein, kidneys, spleen, and hepatic hilum. Images were comparable to human EUS findings, with some remarkable differences. The pancreas was relatively larger in swine and in contrast to humans has three segments (duodenal, splenic, and connecting lobe). Conclusions: The swine model was a highly realistic teaching model for linear and radial pancreatobiliary EUS and a useful tool for training in the setting of in vivo hands-on sessions.
