Abstract

Purpose: Beginning with the graduating class of 2018, the American Board of Surgery (ABS) requires that residents complete the ABS Flexible Endoscopy Curriculum, Fundamentals of Endoscopic Surgery (FES). This curriculum includes both didactic and simulator training. In the ideal setting residents gain proficiency using simulation prior to performing endoscopies in the clinical setting. This new requirement creates an increased demand for endoscopic simulators in all General Surgery residency programs. Due to the cost prohibitive nature of virtual reality simulators an economic alternative is needed.

Methods: A mechanical simulator was created from inexpensive items easily acquired at a hardware store and in the hospital. Total cost of the simulator was approximately $120 USD. To validate the simulator, experienced endoscopists completed a training session with the device. A seven-question Likert scale survey (1 - strongly disagree to 5 - strongly agree) was completed after the session evaluated the simulated experience versus live upper endoscopies and the device's ability to meet the goals of the FES curriculum.

Results: Eight proficient endoscopists completed the training session and survey and agreed that the device closely replicated live colonoscopies and would meet all training requirements in the FES curriculum. Mean responses to all seven survey questions ranged from 3.8-4.4.

Conclusion: This device is a cost-effective method for simulating live upper endoscopies and is appropriate for use in FES training.
