Résumé

Background: Endoscopic ultrasound-guided fine-needle aspiration ă (EUS-FNA) is essential in the management of digestive cancers. However, ă teaching and learning this technique remain challenging due to the lack ă of cost-effective models. ă Material and methods: This was a prospective experimental study using a ă complete porcine upper gastrointestinal ex-vivo organ package, placed in ă an Erlangen Active Simulator for Interventional Endoscopy (EASIE-R), and ă prepared with one cyst and two solid masses (2cm). Five fellows ă inexperienced in EUS-FNA were enrolled, performing 10 procedures on each ă lesion, alternatively. The total time, number of attempts for success, ă of needle view losses, and of scope handling were recorded, associated ă with an independent skills rating by procedure. We compared the first 15 ă procedures with the last 15 for each fellow. ă Results: The fellows successfully performed all procedures in 2 to 40 ă minutes, requiring 1 to 6 attempts. All (5/5) improved their total time ă taken (P<0.001), number of times when the EUS view of the needle was ă lost (P<0.05), scope handling (P<0.005), and skills rating (P<0.001), ă whereas 4/5 (80 %) improved their number of attempts. The overall ă evaluation showed a significant decrease (P<0.001) in the total time ă taken (11.2 +/- 7.8 vs 4.3 +/- 2.2 minutes), number of attempts (2.6 +/- ă 1.2 vs 1.2 +/- 0.7), number of times when the EUS view of the needle was ă lost (2.3 +/- 2 vs 0.5 +/- 0.7), and need for scope handling (1.1 +/- ă 1.7 vs 0.1 +/- 0.2). We also observed an improvement in skills rating (5 ă +/- 1.9 vs. 7.7 +/- 1.1). ă Conclusion: This newly designed ex-vivo model seems to be an effective ă way to improve the initial learning of EUS-FNA, by performing 30 ă procedures.
