Simulator training improves practical skills in therapeutic GI endoscopy: results from a randomized, blinded,...

Area of Science:

• Gastroenterology
• Medical Education
• Surgical Simulation

Background:

• Therapeutic endoscopic procedures are complex and carry higher risks for less-experienced practitioners.
• There is limited evidence on the effectiveness of training methods for these procedures.

Purpose of the Study:

• To evaluate the impact of knowledge-based teaching versus hands-on simulation-based skills training.
• To assess training efficacy in four key therapeutic endoscopic procedures.

Main Methods:

• A single-blind, randomized controlled trial was conducted with participants in a nationally accredited therapeutic endoscopy course.
• Participants were assessed on knowledge (multiple-choice questionnaire) and practical skills (checklists, global score) before and after interventions.
• Interventions included knowledge-based teaching and/or one-half day of hands-on skills training; a control group received no skills training.

Main Results:

• Knowledge-based teaching alone did not significantly improve practical skills or knowledge scores.
• Hands-on skills training led to significant performance improvements in polypectomy, upper GI bleeding control, and esophageal dilation.
• No significant performance differences were observed for percutaneous endoscopic gastrostomy (PEG) tube insertion.

Conclusions:

• Intensive hands-on, simulation-based endoscopic skills training demonstrably improves procedural performance.
• Knowledge-based teaching alone is insufficient for measurable skill enhancement in therapeutic endoscopy.
• The collaborative nature of PEG tube insertion may influence performance outcomes independent of specific training.
