“…Existing literature [3][4][5][6][7][8] focuses largely on descriptions of techniques, simulation model fidelity, and validation of assessment techniques but not necessarily on the study of instructional techniques or educational gains achieved. Limited experience with laboratory-based vascular anastomosis instruction has demonstrated immediate improvements in final product quality for junior resi-dents 9 and has correlated certain measures of laboratory performance with live operating room performance. 10 Laboratory-based training of skin-flap creation has been shown to improve scores on a written examination, but effect on technical skill was not measured.…”

“…However, some of these models may be adopted for a more general usage by changing the size of the particular model. Tubes of different artificial material like silicone, Gore-Tex, latex and PTFE have been used for vascular anastomosis training [3,5,7,11,13]. However, there may be some expense with vascular tube grafts if unsatisfactory amounts are found as leftovers from the operating room.…”

“…We use individualised verbal feedback during anastomotic suturing and after the anastomosis is performed by discussing every single stitch with the trainee to objectify the grade of anastomosis leakage. However, several other methods to assess the operative performance have been described, such as grading possible anastomotic leakage or the motor handling of the surgical instruments quantitatively [3,5,19]. These methods can be used as required.…”

“…These methods can be used as required. Laboratory-based surgical skills training, including vascular anastomosis training, has been demonstrated to improve surgical performance substantially [20]. In this context, it has been previously stated that verbal feedback from an expert instructor leads to lasting improvements in technical performance when learning new surgical skills [21].…”

Description and evaluation of a bench porcine model for teaching surgical residents vascular anastomosis skills

et al. 2010

BackgroundNumerous models, of variable quality, exist to impart the complex skills required to perform vascular anastomosis. These models differ with regard to the kinds of materials used, as well as their sizes, the time needed for their preparation, their availability, and the associated costs. The present study describes a bench model that uses formalin-fixed porcine aorta, and its evaluation by young surgical residents during a recent skills course.FindingsThe aortic segments used were a by-product of slaughtering. They were fixed and stored after harvesting for eventual use. Ten young surgical residents participated, and each performed one end-to-side vascular anastomosis. The evaluation was a questionnaire maintaining anonymity of the participant containing questions addressing particular aspects of the model and the experiences of the trainee, along with their ratings concerning the need for a training course to learn vascular anastomosis techniques. The scoring on the survey was done using a global 6-point rating scale (Likert Scale). In addition, we ranked the present model by reviewing the current literature for models that address vascular anastomosis skills.The trainees who participated were within their first two years of training (1.25 ± 0.46). A strong agreement in terms of the necessity of training for vascular anastomosis techniques was evident among the participating trainees (5.90 ± 0.32), who had only few prior manual experiences (total number 1.50 ± 0.53). The query revealed a strong agreement that porcine aorta is a suitable model that fits the needs for training vascular anastomosis skills (5.70 ± 0.48). Only a few bench models designed to teach surgical residents vascular anastomosis techniques were available in the literature.ConclusionsThe preparatory and financial resources needed to perform anastomosis skills training using porcine aorta are few. The presented bench model appears to be appropriate for learning vascular anastomosis skills, as rated by the surgical trainees themselves.

“…O ensino de anastomoses vasculares é um tema já validado em programas de residência em cirurgia vascular, pois esta técnica é uma das primordiais para o dia-a-dia da especialidade (8)(9) . Entretanto, a anastomose arteriovenosa latero-lateral é pouco ensinada em graduação, portanto, avaliar a curva de aprendizado desta técnica em graduandos em medicina, configura uma inovação do uso do modelo de bancada com línguas bovinas.…”

Introdução: A anastomose arteriovenosa latero-lateral é um procedimento complexo para acadêmicos de medicina, pois requer treinamento repetitivo. Objetivo: Comparar o aprendizado de alunos do quinto e décimo semestres da graduação de medicina, após treinamento de anastomose arteriovenosa latero-lateral, em modelo para treinamento que utiliza línguas bovinas. Materiais e Métodos: Estudo realizado na Universidade Nove de Julho, São Paulo, SP, Brasil, com a participação de 20 graduandos de medicina (dois grupos de dez alunos, de quinto e décimo semestres). No primeiro dia os alunos assistiram aula sobre a técnica da anastomose arteriovenosa latero-lateral e realizaram o procedimento, sendo avaliados dez critérios quanto à realização do procedimento. Os grupos treinaram durante quatro sessões de duas horas e foram novamente submetidos à mesma avaliação. As notas médias foram analisadas pelo teste T de Student. Resultados: O grupo de quinto semestre obteve média de 3 pontos na avaliação 1 e 5 pontos na avaliação 2 (p = 0,08393). O grupo de décimo semestre obteve média de 5 pontos na avaliação 1 e 7 pontos na avaliação 2 (p = 0,08393). Conclusões: Comparando o desempenho dos alunos de quinto e décimo semestre, após treinamento específico da anastomose vascular proposta, houve melhora na nota dos dois grupos, mas não houve significância estatística quando os valores foram comparados.
