Introduction: Endoscopic simulators have been demonstrated to improve endoscopic technical skills for gastroenterology trainees. However, the precise learning curves for the development of endoscopic technical skills in a simulator-enhanced fellowship training curriculum has not been previously reported or validated. Here, we present the experience and learning curves of two first-year adult gastroenterology fellows working with the Thompson Endoscopic Skills Trainer (TEST).

Methods: This was a longitudinal quality improvement initiative involving two first-year fellows at the ACGME-accredited University of Texas MD Anderson Cancer Center adult gastroenterology fellowship program, who incorporated the routine use of the TEST into their endoscopy training curriculum over the course of their fellowship training. The TEST has 5 exercises to develop and supplement the endoscopic skills of retroflexion, polypectomy, torque, scope tip control, and navigation and loop reduction. Each fellow completed 20 sessions over a 6 week period, which were scored based on the TEST instructions. Each exercise had 10 objectives worth 10 points each, and 5 minutes were given to complete all 10 objectives. Each extra second remaining would add 1 point to the score. Each fellow completed 1-3 sessions per day.

Results: After 20 sessions, each fellow’s total score on the TEST increased approximately 250% percent (Figure 1 & Table 1). As more sessions were completed by each fellow, overall scores increased and amount of time needed to complete the exercises also decreased, demonstrating improvement in endoscopic technical ability.

Discussion: Formal incorporation of endoscopic simulators such as the TEST facilitated sustained improvement in endoscopic skill over the course of the first year of gastroenterology fellowship. The results of this unique learning curve study support the role of endoscopic simulator-based training in allowing trainees to safely and effectively enhance their endoscopic technical ability in conjunction with traditional patient-centered endoscopy training. Ongoing studies will seek to further validate these findings throughout fellowship training and among additional trainees.
