背景：超声内镜引导下细针穿刺（EUS-FNA）在消化道肿瘤的治疗中至关重要。然而，教学和学习这项技术仍然具有挑战性，由于缺乏成本效益models.Material和方法：这是一个前瞻性的实验研究，使用一个完整的猪上消化道离体器官包，放置在一个埃尔兰根主动模拟器介入内镜（EASIE-R），并准备一个囊肿和两个固体肿块（2厘米）。入组了5名EUS-FNA经验不足的研究员，对每个病变交替进行10次手术。记录总时间、成功尝试次数、针视图丢失次数和内镜操作次数，并按手术进行独立技能评级。我们比较了前15个程序与最后15个为each fellow.Results：研究员成功地进行了所有程序在2至40分钟，需要1至6次尝试。所有患者（5/5）的总用时均有所改善（P
Background: Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is essential in the management of digestive cancers. However, teaching and learning this technique remain challenging due to the lack of cost-effective models.Material and methods: This was a prospective experimental study using a complete porcine upper gastrointestinal ex-vivo organ package, placed in an Erlangen Active Simulator for Interventional Endoscopy (EASIE-R), and prepared with one cyst and two solid masses (2cm). Five fellows inexperienced in EUS-FNA were enrolled, performing 10 procedures on each lesion, alternatively. The total time, number of attempts for success, of needle view losses, and of scope handling were recorded, associated with an independent skills rating by procedure. We compared the first 15 procedures with the last 15 for each fellow.Results: The fellows successfully performed all procedures in 2 to 40 minutes, requiring 1 to 6 attempts. All (5/5) improved their total time taken (P
