 Abstract
 PDF
- Esophagogastroduodenoscopy (EGD) is a fundamental diagnostic and therapeutic modality for various gastrointestinal diseases. As endoscopic techniques evolve, mastering the step-by-step process of EGD—including insertion, navigation, and systematic observation—is essential for ensuring patient safety and diagnostic accuracy. This video article provides a comprehensive, narrated demonstration of the techniques involved in EGD, from patient preparation to scope control and anatomical orientation. It emphasizes key technical details such as endoscope handling, the role of hand movements in scope navigation, and systematic evaluation of the esophagus, stomach, and duodenum. All demonstrations were performed using a simulation model (UGI Endoscopy Simulator; MEDICAL IP, Korea) with an Olympus GIF-HQ290 endoscope. This educational video serves as a practical guide for trainees seeking to refine their technique and increase procedural efficacy.

Abstract
- Background
Integrating structured colonoscopy training into general surgery residency programs remains both a logistical and educational challenge. This study evaluated the feasibility and educational outcomes of a standardized colonoscopy training curriculum for surgical residents using objective competency assessments and trainee perceptions.
Methods
A retrospective mixed-methods analysis was conducted among general surgery residents who participated in a standardized colonoscopy training program between 2022 and 2025. Faculty assessed objective procedural competency using the Direct Observation of Procedural Skills framework across three domains: basic manipulation, anatomical understanding, and insertion & advancement. Trainee perceptions regarding the training environment, procedural difficulty, and perceived educational value were evaluated using a post-training survey.
Results
Objective competency data from 369 residents were analyzed. Residents demonstrated high performance in the basic manipulation and anatomical understanding domains following completion of the training program. In contrast, scores in the insertion & advancement domain were comparatively lower, suggesting greater technical difficulty. Post-graduate year (PGY)-3 residents achieved significantly higher scores than PGY-2 residents in this domain (p=0.015), whereas performance in the other domains was comparable between the groups. Post-training survey responses indicated that most residents considered the training duration and group size appropriate, and more than 94% reported that the program would be beneficial for their future clinical practice.
Conclusions
A standardized colonoscopy training curriculum implemented during surgical residency was feasible and was associated with high levels of competency in fundamental endoscopic skills. However, insertion and advancement techniques remained more challenging for junior trainees, suggesting that additional practice opportunities targeting complex insertion skills may improve future training programs.
