Bariatric Surgical Simulation: Evaluation in a Pilot Study of SimLife, a New Dynamic Simulated Body Model.

Area of Science:

• Surgical Education
• Medical Simulation
• Bariatric Surgery Training

Background:

• High demand for bariatric surgery necessitates effective surgeon training.
• Bariatric surgery's technical demands create a learning curve with potential for increased morbidity.
• Preclinical simulation training can mitigate the clinical impact of the surgical learning curve.

Purpose of the Study:

• To conduct a face validation study of the SimLife dynamic cadaveric model for surgical skills acquisition.
• To assess the realism, learner satisfaction, and learning potential of the SimLife model.
• To evaluate the model's suitability for simulated bariatric surgery (sleeve and Roux-en-Y gastric bypass).

Main Methods:

• The SimLife model utilizes a fresh, frozen/thawed cadaver.
• It features a patented module providing pulsatile vascularization with simulated blood (37°C) and ventilation.
• The study involved 24 surgical residents and chief residents from French university departments.

Main Results:

• The cadaveric model received high ratings for overall satisfaction (8.52), realism (8.91), and anatomical correspondence (8.64).
• Learners rated the model's effectiveness as a learning tool at 8.78.
• The study demonstrated strong positive feedback from participants regarding the model's features.

Conclusions:

• The SimLife model provides a highly realistic platform for surgical simulation.
• It enables effective training and objective performance evaluation for young surgeons.
• This cadaveric model is a valuable tool for preparing surgeons for complex bariatric procedures.
