The Gastric Model is designed to simulate essential procedural steps for both sleeve gastrectomy and gastric bypass. The model includes a stomach with varying wall thicknesses to facilitate training with different staple sizes. This includes an over exaggerated thick lateral wall, allowing users to troubleshoot incorrect staple size selection. 

For sleeve gastrectomy, it supports port placement, mobilisation of the greater curvature, identification of the diaphragmatic hiatus, posterior mobilisation, bougie placement, creation of the stapled sleeve gastrectomy, endoscopy, and closure of the fascia and skin. 

For gastric bypass, the model supports port placement, mobilization of the greater curvature, identification of the diaphragmatic hiatus, creation of a gastric pouch, creation of the biliopancreatic (BP) limb, jejunojejunostomy, gastrojejunostomy, and endoscopy.
