Procedural simulation is an innovative educational method that provides a safe environment for learning diagnostic digestive endoscopy techniques. It complements traditional apprenticeship-based clinical training, thereby reducing risks to patients. Since the introduction of simulators at the Simulation Center in Marrakech, this approach has been integrated into gastroenterology resident training.

The objective of this study was to evaluate the effectiveness of procedural simulation-based learning for residents in diagnostic digestive endoscopy.

This prospective cross-sectional study involved 13 first- and second-year gastroenterology residents aged 26 to 28 years. Training was conducted at the Simulation Center using low-fidelity simulators under the supervision of experienced instructors. The training protocol included repeated and progressive practical sessions, followed by two types of assessments. Self-assessment was performed by the residents before and after training. External assessment was conducted by instructors to evaluate technical skills, including endoscope handling, navigation, and anatomical recognition, as well as behavioral competencies.

Results showed that all 13 residents reported significant improvement in technical skills in the self-assessment, with an average gain of 45 percent. Instructor evaluation confirmed notable progress in mastering technical gestures, with improved performance in both upper and lower endoscopy. The average satisfaction score among participants, measured on a scale from 1 to 5, was 4.3 ± 0.6, indicating high perceived effectiveness and usefulness of the training. Instructors also noted improvement in relational skills and professional behavior. Only one resident reported minimal progression, perceiving no change in skills after the training.

In conclusion, procedural simulation is an effective educational method that allows gastroenterology residents to rapidly acquire the technical skills required for diagnostic digestive endoscopy. Residents demonstrated significant progress in a safe learning environment with high satisfaction, supporting the systematic integration of procedural simulation into gastroenterology training programs.
