ABSTRACT
Introduction: the elevated risk of complications and technicalcomplexity of endoscopic submucosal dissection (ESD) has limitedits implementation in our medical system.Objective: to design and evaluate a training program forlearning the ESD technique.Methods: four endoscopists with no experience with ESD underwenta 4-step training program: 1) review of the existing literature,didactic material, and theoretical aspects of ESD; 2) ESDtraining in an ex-vivo animal model; 3) ESD training in an in-vivoanimal model (supervised by ESD expert); and 4) ESD performancein a patient. A standard gastroscope and an ESD knife (IT,Flex or Hook-knife Olympus®) were employed. The classical ESDtechnique was performed: rising of the lesion, circumferential incision,and submucosal dissection.Results: ex-vivo animal model: 6 x swine stomach/esophaguscost < 100 euro; 6 x ESD: antrum (n = 2), body (n = 3) andfundus/cardia (n = 1); size of resected specimen: 4-10 cm; ESDduration: 105-240 minutes; therapeutic success: 100%; complications:perforation (1/6: 16%) sealed with clips. In-vivo animalmodel: 6 ESD (antrum/body of stomach: 4; esophagus: 2); size:2-5 cm; duration: 40-165 minutes; success: 100%; complications:0%. Patient: ESD of a gastric lesion located in theantrum/body; size: 3 cm; duration 210 minutes; a complete resectionwas achieved; no complications.Conclusions: the results of the present study support the usefulnessof this model for learning ESD in our system(AU)
