Enhancing Colonoscopy Training Through Simulation-Based Training: Designing and Evaluating an Interactive Graphical...

Area of Science:

• Medical Simulation
• Surgical Training
• Gastroenterology

Background:

• Colonoscopy is crucial for colon cancer prevention, reducing risk by up to 90%.
• High miss rates for cancerous polyps (up to 20%) are linked to surgeon inexperience.
• Existing colonoscopy simulators lack essential real-time feedback, hindering effective training.

Purpose of the Study:

• To design a graphical user interface (GUI) to enhance colonoscopy training.
• To address the limitations of current simulators, specifically the lack of real-time feedback.
• To improve the learning curve and performance of medical residents in colonoscopy procedures.

Main Methods:

• A two-phase study involving 10 semi-structured interviews with experts.
• A usability study with 10 participants to evaluate the developed GUI.
• Incorporation of real-time and post-training feedback features within the GUI.

Main Results:

• Simulators were found to inadequately mimic patient colonoscopies and lack real-time feedback.
• Medical residents reported difficulties with scope navigation and loop reduction.
• User testing indicated satisfaction with the GUI, with feedback on polyp detection, cecal intubation time, and force being perceived as valuable.

Conclusions:

• The developed GUI offers a promising solution for improving colonoscopy training.
• Real-time and post-training feedback are critical components for enhancing trainee performance.
• This GUI has the potential to significantly improve polyp detection and overall colonoscopy outcomes.
