ABSTRACT
BackgroundWithin the competencies in education for general surgery residents, the development of Laparoscopic Surgery Skills is of the utmost importance. We evaluated the usefulness of cadavers preserved with a formaldehyde-free solution in the acquisition/development of Skills for Laparoscopic Surgery once basic skills have been developed.MethodsThis is a single-center, single-blind, randomized educational intervention clinical trial. Participants took a theoretical and practical module on the acquisition of skills in laparoscopy and took a pre-test focused on intracorporeal enterorrhaphy. Subsequently, they were randomized by blocks into 3 branches continuing their training in skill acquisition models, silicone models, or Formaldehyde-free solution preserved corpses, and finally they performed a post-test. Two blind experts evaluated participants using the GOALS and OSATS scales for laparoscopic surgery.ResultsN = 37 participants were obtained. No relationship was found between the branch and the results of the GOALS and OSATS tests in pre and post-test, which implies comparability between the training methods. Also, the Pillai’s Trace statistical test for the MANOVA (0.95, F(12, 54) = 4.0988, P < 0.05) and (0.66, F(2, 31) = 30.18, P < 0.05) indicates that the educational level of the participant does have a statistically significant association with the results obtained in the pre- and post-test.ConclusionsEducation and development of laparoscopic surgery skills using cadavers preserved with the presented formaldehyde-free solution is comparable to other simulation models for the acquisition of skills in minimally invasive surgery. Also, this tool improves the learning curve in subjects with no prior experience.
