Abstract
Effective endoscopy training begins by assessing the trainee's experience and identifying their skill level: beginners, learners, independent practitioners, or experts. Beginners focus on basic tasks, such as cecal intubation, while advanced trainees refine efficiency and complex techniques. Training prioritizes conscious competence through deliberate practice, reflection, and verbalizing actions; this enhances mindfulness and procedural expertise. Clear communication, standardized terminology, and constructive feedback ensure safety, confidence, and skill retention. SMART objectives-specific, measurable, achievable, relevant, and timely-help structure sessions for skill development and mastery. Simulation-based models support training at all the levels. Beginners benefit from cost-effective low-fidelity bench models and virtual reality (VR) simulators, which offer realistic tactile feedback and customizable scenarios. Studies have shown that both low- and high-fidelity models can effectively teach basic skills, although VR is preferred for foundational training. Advanced trainees utilize animal-based models for therapeutic interventions, three-dimensional printed models for pathology-specific practice, and hybrid models that combine VR and physical elements for enhanced realism. Augmented reality and haptic feedback systems refine advanced skills, but face developmental and cost challenges. Mentored live patient models excel in real-world decision-making, but raise ethical concerns. Training is tailored to individual needs, and competency-based training ensures mastery at each stage, from beginners to advanced practitioners.
