For the acquisition of skills in laparoscopic surgery, practices in experimental labs are gaining increasing relevance. Activities in experimental labs include Pelvitrainers, virtual reality simulators, and experimental animals (frequently pigs). However, the best model for surgical formation is the performance of interventions on cadavers. The Thiel method gives the body elasticity, which allows the performance of laparoscopic procedures.


An observational prospective study was performed on surgeons attending to two courses of laparoscopic bariatric surgery on cadavers embalmed by the Thiel method. A questionnaire was given to the participants (students and professors) when finishing the course. Similarities between the procedures performed on cadavers and on patients were investigated. The satisfaction degree was also analyzed.


The students recognized that the Thiel cadaver presents elasticity and aspect similar to the patient, and the practice on cadavers is considered the best method for the formation in laparoscopic bariatric surgery. The assistants were extremely satisfied with the acquired skills and considered that these courses should be included in the formation programs for bariatric surgery. The results of the survey on professors agreed with the students in considering the practice on cadavers as the best method for the formation in laparoscopic bariatric surgery. However, they highlighted as drawbacks of the Thiel cadaver, the absence of bleeding, and excessive elasticity of the tissues.


The participants (students and professors) to the courses of laparoscopic bariatric surgery on cadaver Thiel recognize that these are the most similar model to real conditions in bariatric surgery.
