POSTER ABSTRACTS: THERAPEUTIC: P-THER-02: A realistic, simple, inexpensive endoscopic ultrasound-guided biliary drainage training model using three-dimensional printing bile duct and mixed gelatin material

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided biliary drainage (EUS-BD) is one of the advance therapeutic EUS procedures that require a learning curve. Several training models and biliary duct prototype have been developed, but each has its own merits and limitations. The authors have created a mixed gelatin model with three-dimensional (3D) bile ducts that is feasible, realistic, durable, and inexpensive. MATERIAL AND METHODS: The models combined with a mixed-gelatin material and 3D printing of different type biliary systems. They are applicable for multiple usage during training in punctures, aspirations, stents placement, and removal technique. Evaluation of the models regarding its overall applicability, quality of EUS images, and four steps of EUS-BD procedure (needle puncture, guidewire manipulation, tract dilation, stent placement) was noted. RESULTS: A single mixed gelatin model can be applied at least four punctures with sustainable good quality. Preliminary surveys demonstrated that good ratings such as bile duct can be identified clearly, and needle puncture, dilate, and stenting can be performed with realistic resistance feeling. The echogenicity and ultrasonography imaging were comparable to human visceral organs. In addition, there was no need to concern about hazard control and dangers from animal-related disease. CONCLUSION: A 3D printing bile duct with mixed gelatin model for EUS-guided biliary drainage is cost-effective, feasible, realistic, and safe
