Formaldehyde-free Embalmed Cadavers as a Training Tool in a Multimodal Structured Curriculum in Laparoscopic Surgery:...

Area of Science:

• Surgical Education
• Minimally Invasive Surgery Training
• Medical Simulation

Background:

• Developing laparoscopic surgery skills is crucial for general surgery residents.
• This study assesses formaldehyde-free preserved cadavers for advanced laparoscopic skill acquisition.
• Existing basic skills are a prerequisite for this advanced training.

Purpose of the Study:

• To evaluate the efficacy of formaldehyde-free preserved cadavers in laparoscopic surgery skill development.
• To compare formaldehyde-free cadavers with traditional skill acquisition models.
• To determine the impact of prior experience on skill acquisition outcomes.

Main Methods:

• A single-center, single-blind, randomized educational intervention trial.
• Participants underwent theoretical and practical modules with pre-testing on intracorporeal enterorrhaphy.
• Trainees were randomized into three groups: skill acquisition models, silicone models, or formaldehyde-free cadavers, followed by post-testing.

Main Results:

• No significant difference in GOALS and OSATS scores between training groups, indicating comparability.
• Participant's educational level significantly impacted pre- and post-test results (MANOVA, P < 0.05).
• N = 37 participants were included in the study.

Conclusions:

• Formaldehyde-free cadavers provide comparable laparoscopic surgery skill development to other simulation methods.
• This preservation technique is effective for minimally invasive surgery training.
• The formaldehyde-free cadaver model accelerates the learning curve for inexperienced individuals.
