| Core Tip |
Endoscopic ultrasound (EUS)/EUS-elastography simulation reduces the learning curve. In this study, the mechanical properties of polyvinyl alcohol hydrogel were standardized to simulate digestive organs and lesions. Polyvinyl alcohol hydrogel (PVA)-hydrogels with stable mechanical properties were obtained; the density depended on the molecular weight (MW) and its concentration (C), the PVA-hydrogels with the highest density showed less tensile strength. All lesions were visible by EUS/EUS-Elastography; those that were homogeneous and heterogeneous were created with hydrogels of higher density (MW2, C9 and C10) and lower (MW1, C1 and C2), respectively. In conclusion, PVA-hydrogels are appropriate for simulating organs and digestive lesions, facilitating practice and reducing risk. |
