EUS-guided cystogastrostomy is a well-established advanced endoscopic technique with steep-learning curve which necessitates an ex-vivo simulator that would allow for adequate training. The aim of this study to evaluate the feasibility model in allowing training using lumen-apposing metal stent (LAMS).The was created by ROEYA Training Center, Egypt, native porcine tissue create fluid collections simulating both cystic and solid lesions. It designed tested advance while hydrogel added on-site. evaluated prospectively five sessions involving 17 international experts. task successfully deploy LAMS drain cyst. After simulator, experts were asked fill questionnaire assess their experience. primary endpoint overall satisfaction as tool.All satisfied tool train endoscopists technique. 76.5% (n = 11) thought be moderately realistic. Proper visualization reported 94.1% All believed lesions either slightly like or very similar real graded "easy" difficulty 11 experts.In all parameters assessed, useful future This preliminary suggests aforementioned can used on risk-free environment.
