An adequate level of training for technically competent colonoscopic polypectomy.

Area of Science:

• Gastroenterology
• Medical Education
• Surgical Skills Training

Background:

• Technical competence in colonoscopic polypectomy (CP) among trainees is not well-defined.
• The learning curve for achieving proficiency in CP requires further investigation.

Purpose of the Study:

• To investigate the learning curve for colonoscopic polypectomy (CP) among trainee endoscopists.
• To determine the number of procedures required for trainees to achieve technical competence in CP.

Main Methods:

• Compared CP times and en bloc resection rates of experienced endoscopists with those of trainees.
• Defined trainee success as en bloc resection within twice the median time of experts.
• Established technical competence at an 80% success rate for trainees.

Main Results:

• Trainees achieved an 80% success rate after approximately 250 procedures.
• Trainee CP time decreased and en bloc resection rates improved with experience.
• Experience was an independent predictor of successful CP.

Conclusions:

• Approximately 250 colonoscopic polypectomy procedures are needed to achieve technical competence.
• Dedicated education and training programs for CP are recommended for trainees.
