The model consists of three main components: a reusable silicone rubber stomach and duodenum (The Chamberlain Group, Great Barrington, MA), a 3D printed ampullary mount to which the chicken heart is attached, and a 3D printed base to stabilize the duodenum and to act as a guide to allow repeated insertion and extraction of the mount. The base allows the simulated ampulla to enter the duodenum perpendicular to the wall of the model through a 14mm opening. The mount has a 2.5mm pancreatic duct and a 4mm bile duct. The model allows for successful completion of ampullectomy procedural steps, including passing an ERCP scope through the pylorus to the ampulla, identification of the ampulla, positioning the snare over the ampulla, performing snare resection, specimen retrieval, pancreatic duct cannulation, and pancreatic stent insertion.
