To determine if practicing an aorto-saphenous vein anastomosis on a low-fidelity surgical simulator allows trainees to produce a higher quality anastomosis in a shorter period of time, than a group that only learns by watching a video.

Condition Intervention
Education, Medical
Device: Surgical simulator to practice vascular anastomosis

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double-Blind
Primary Purpose: Educational/Counseling/Training
Official Title: Benefits of a Surgical Skills Lab Vascular Anastomosis Simulator: A Randomized Controlled Trial

Further study details as provided by Lawson Health Research Institute:

Primary Outcome Measures:
  • Quality of final vascular anastomosis based on validated scale

Secondary Outcome Measures:
  • Global rating of operative skill based on validated scale (final anastomosis)
  • Time taken to complete final anastomosis
  • Time taken to complete initial and final anastomosis (experimental group only)
  • Anastomotic leakage for final anastomosis
  • Anastomotic patency for final anastomosis

Estimated Enrollment: 40
Study Start Date: May 2006
Estimated Study Completion Date: September 2007
Detailed Description:

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.
