Evaluation of Surgical Simulator for Practicing a Vascular Anastomosis

For many years, surgical training has been considered an apprenticeship, where the training experiences of residents, have been in real operative settings on living patients. We propose a study to demonstrate that - a low-fidelity simulation of an aorta-proximal vein graft anastomosis as in heart bypass surgery, using anatomical replicates (a special hydrogel polymer with properties similar to human vascular tissue) - is an effective, low-cost simulator for learning this surgical skill, and will provide the trainee with the ability to perform a better anastomosis in a shorter period of time.

Hypothesis: Practicing an aorto-saphenous vein anastomosis on a low-fidelity surgical simulator will advance the trainees' learning curve. This will allow trainees to produce a higher quality anastomosis in a shorter period of time, than a group that only learns by watching a video and will lead to enhanced patient safety.

Inclusion criteria

• 1st year surgical resident at The University of Western Ontario
• Anastomosis naive - the subject must not have performed a human vascular anastomosis in the past (it is acceptable if they have observed one being performed in the past)

Exclusion criteria

• Completed a human vascular anastomosis as the primary operator/surgeon in the past
