“…Tal trabalho contou com uma avaliação do desenvolvimento de uma habilidade não muito pesquisada e valorizada na prática do ensino dos estudantes de medicina: a incisão, tendo em vista uma diversidade de trabalhos que estão voltados para o ensino de suturas, por exemplo. Nesse sentido, é importante incentivar o desenvolvimento e o aprimoramento de diversas habilidades cirúrgicas e, preferencialmente, desde a graduação [3][4][5]9 .…”

“…Alguns desses procedimentos são utilizados em situações de emergência e devem ser do domínio técnico de todos, visando a não expor os pacientes a riscos desnecessários 3 . Dessa forma, tendo em vista que a maioria dos estudantes não recebe treinamento satisfatório para procedimentos cirúrgicos básicos durante a graduação, é necessária a implementação de um programa de ensino dessas técnicas seguindo as novas tendências de substituição do uso de animais em pesquisas e treinamentos 4,5 . Então o presente estudo pretende desenvolver modelos experimentais alternativos no treinamento de incisões cirúrgicas para treinamento de estudantes de Medicina.…”

Summary Purpose: to develop a course with an experimental alternative model on surgical incision for medical students without training. Methods: 10 male and 10 female students of the 2nd and 3rd years of medical school, without previous surgical training, participated. After an instructive class on surgical incisions, they underwent training in four alternative models: ham with cheese; banana; orange and bacon. In each model were executed linear incisions, circular, square and elliptical. The following were evaluated: the ability to perform a complete or incomplete incision, number of lesions in the fruits when the bark was completely sectioned or with exaggerated depth, and the time required to perform the task. The students were evaluated with the same exercises twice, with the gap of one week, in which they trained at home for approximately 15 minutes per day. The data from the evaluation were annotated in a standard form and statistically compared by the tests of Friedman and test T, being the data of each student control of his own. Results: Regarding the evolution in the time of the incisions, there was a non-significant decrease in the mean, of 29.8 sec. To 28.0 sec. (P = 0.11175). The same occurred with the number of lesions, which dropped from 9.95 to 8.70 (p = 0.8231). When the complete incisions were analyzed, there was a statistically significant increase in the means, which went from 12.55 to 17.85 (p = 0.0008), while the incomplete ones fell from 14.35 to 9.45 (p = 0.0017). Conclusion: The incision training with alternative models was efficient in gaining cognition and skills in all parameters analyzed, with a statistically significant gain in precision and dexterity in performing the incisions.

“…The ethical issues about teaching and learning on human patients, economical concerns, and mainly the patients referred to our hospitals are sicker and have more complex diseases, have limited the attending surgeons in assisting residents to learn surgical techniques and skills in the operating theater [2][3][4][5] . Thus, many academic-hospitals have turned toward laboratory-based training programs and have prompted the use of many organic and synthetic materials for bench surgical training [6][7][8][9] . High fidelity bench models are the "most realistic" to learn surgical skills 10 .…”

PURPOSE:To present lyophilized esophageal segments that can be used to learn surgical skills. METHODS:Four esophagus were harvested from four non-esophagus related research dogs at the moment of euthanasia. Each esophagus was trimmed in 3 cm long segments. They were lyophilized and stored during 30 days. The day programmed for surgical skills practice, they were rehydrated. RESULTS:Sixteen segments have been used. After rehydrating, all the segments kept their normal anatomic shape and structural integrity. One incision was made on every esophageal segment and sutured with running stitches of 3-0 polyglactin 910. There were no complications, such as tissue tears, nor esophageal hardening. CONCLUSIONS:The lyophilized esophagus is a high fidelity, practical, reproducible, portable, low-cost bench model. It allows general surgery apprentices to learn how to handle an esophagus, as well as to perfect their surgical and suture abilities before applying them on real patient's esophagus.

“…However, ethical/legal and economical issues in the use of human cadavers, live laboratory animals and virtual reality simulators have prompted the use of numerous bench models made of organic or synthetic materials [1][2][3][7][8][9][10][11] . Most of these bench models are focused to trainees in general surgery, but few bench models are available for cardiothoracic fellows.…”

PURPOSE:To present a new low-cost high fidelity bench model of cryopreserved trachea that can be used to learn surgical skills from medical students to cardiothoracic surgery fellows. METHODS: Ten tracheas were harvested from ten non-trachea related research dogs at the moment of euthanasia. Each trachea was trimmed in six or seven rings segments. They were cryopreserved and stored during 60 days. The day programmed for surgical skills practice, they were thawed to room temperature. RESULTS: Forty segments have been used. After defrosting, all the segments kept their normal anatomic shape and structural integrity. Two incisions were made on every tracheal segment and sutured with running or separate stitches with 5-0 polypropilene. There were no complications such as cartilage ruptures, neither tears on the mucosae, the cartilages nor the membranous posterior membrane. CONCLUSIONS: The cryopreserved trachea is a high fidelity, practical, reproducible, portable, low-cost bench model. It allows cardiothoracic fellows to learn how to handle a trachea, as well as to perfect their surgical and suture abilities before applying them on a real patient's trachea. Key words: Trachea. Cryopreservation. Learning. Dogs. RESUMO OBJETIVO: Apresentar novo modelo de traquéia criopreservada de baixo custo e alta fidelidade que pode ser usado tanto por estudantes de medicina como por cirurgiões cardiotorácicos no aprendizado e desenvolvimento de suas habilidades cirúrgicas. MÉTODOS: Foram coletados amostras de dez traquéias de dez cães utilizados para pesquisa após a eutanásia. Cada segmento de traquéia foi dividida em seis ou sete anéis, criopreservadas e armazenadas durante 60 dias. No dia programado para a prática cirúrgica os segmentos foram descongelados a temperatura ambiente. RESULTADOS: Foram utilizados 40 segmentos no estudo. Após o descongelamento todos os segmentos mantiveram sua forma anatômica e sua integridade estrutural. Foram realizadas duas incisões em cada segmento traqueal que foram suturadas em padrão continuo ou com pontos separados utilizando sutura de polipropileno 5-0. Não houve nenhuma complicação como a ruptura da cartilagem, rasgos na mucosa, cartilagem ou na membrana membranosa posterior. CONCLUSÕES: O modelo de traquéia criopreservada é altamente fidedigno, prático, reproduzível, portátil e de baixo custo. Permite que os cirurgiões cardiotorácicos aprendam como manipular a traquéia, assim como aperfeiçoar suas habilidades cirúrgicas antes de sua aplicação em traquéias de pacientes reais.
