Evaluation in a Multimodal Structured Curriculum of Laparoscopic Surgery

Plain-language summary

Development of Laparoscopic surgery skills for general surgery residents are considered competencies of major importance. Different tools are used for this purpose, including synthetic models, virtual reality, animal models and human cadaveric specimens preserved by freezing.Cadaveric models share the anatomical similarity, however have some clear disadvantages including the biological risk and the alteration of the mechanical properties of the bodies preserved by this technique, such as tissue rigidness, lack of elasticity and consistency, and the impossibility of achieving adequate pneumoperitoneum. However, we previosly devoleped a formaldehyde free solution for anatomical preservation. Hence. we propose a a single-center, single-blind, randomized educational intervention clinical trial. Research participants who meet the inclusion criteria have a theoretical and practical module on the acquisition of skills in laparoscopy and take a pre-test focused on intracorporeal enterorrhaphy. Subsequently, they are randomized by blocks into three groups: Negative Control, Positive Control, and Intervention, continuing their training in skill acquisition models, silicone models, or Formaldehyde-free solution preserved corpses, respectively. Finally they are evaluated with a post-test. Two blind experts will evaluate participants using the GOALS and OSATS scales for laparoscopic surgery.
