Area of Science:

  • Gastroenterology
  • Surgical Simulation
  • Medical Education

Background:

  • Endoscopic submucosal dissection (ESD) training requires effective bridging methods between theoretical knowledge and practical application.
  • Novel artificial tissue simulators offer a potential solution for enhancing ESD procedural skills.
  • Evaluating the feasibility and realism of artificial tissue models is crucial for their adoption in training.

Purpose of the Study:

  • To develop and evaluate a novel artificial simulator for endoscopic submucosal dissection (ESD) training.
  • To assess the feasibility and perceived realism of the artificial tissue model for ESD training.
  • To determine the impact of the simulator on fellows' confidence in performing specific ESD techniques.

Main Methods:

  • Eight gastroenterology fellows participated in an ESD training program utilizing an artificial tissue simulator.
  • Participants rated the difficulty of ESD procedures (lesion marking, pre-cutting, incision, dissection, hemostasis) before and after simulator training.
  • A post-training questionnaire assessed the simulator's realism and feasibility for ESD training.

Main Results:

  • Simulator training significantly increased fellows' confidence in lesion marking (p=0.026) and submucosal dissection (p=0.037).
  • Hemostasis remained the most challenging technique post-training.
  • Trainees found the simulator realistic for lesion marking and feasible for lesion marking and submucosal dissection.

Conclusions:

  • The novel artificial tissue simulator is a feasible tool for endoscopic submucosal dissection (ESD) training.
  • The simulator effectively bridges the gap between instructional videos and animal model training.
  • This reusable and inexpensive model can facilitate wider dissemination of ESD techniques.
