“…Despite all these advantages, there are limiting factors such as the 3R principle, ethics, or the association with legal problems in some countries, which results in microsurgical models in synthetic material being offered to replace the above (24)(25)(26) . Far from opposing this idea, we consider that any experimental program should start with synthetic models and end with live animal models, since they are the ones that most closely resemble human surgery and represent an essential step that gives the surgeon confidence and technical skill (4,10,27) .…”

Objective. To describe a basic training program in microsurgery and to analyze the learning curve through the process, including improvement in operating times and functional outcome.Materials and methods. Our learning program included basic, transitional, and experimental models. The experimental model included tail vein cannulation, intestinal resection and anastomosis, dissection, division and anastomosis of the cava and aorta. Wistar rats (66.7% male; 406.9 ± 38.9 grams) were used. The program adhered to the 3R principle and obtained animal welfare committee approval.Results. Mean tail vein cannulation time was 2.4 ± 1.2 minutes. Mean intestinal resection and jejunocolic anastomosis time was 14.8 ± 2.7 minutes and 10.4 ± 3 minutes, respectively. All anastomoses were functionally valid. Mean vessel dissection time was 22.9 ± 7.7 minutes, aortic artery anastomosis was 17.2 ± 7.1 minutes, and vena cava anastomosis was 25.9 ± 7.3 minutes. 66.7% of vena cava anastomoses were functionally valid vs. 88.9% for the aorta. The time required for all procedures decreased after the third attempt, except for vena cava anastomoses, which remained similar in all 9 procedures. Conclusions. Our model demonstrated that the procedures were suitable for trainer progression in terms of surgical time and functional outcome. Microsurgical training would benefit from standardized programs to optimize results.

“…Frente a todas estas virtudes, existen cuestiones limitantes como, el principio de las 3R, la ética o la asociación con problemas legales en algunos países, resultando que los modelos de microcirugía en material sintético se ofrezcan para sustituir a los anteriores (24)(25)(26) . Lejos de oponernos a esta idea, consideramos que todo programa de experimentación debería empezar por modelos en material sintético para terminar con modelos de animales vivos, ya que son los que más se asemejan a la cirugía humana y suponen un paso esencial que aporta seguridad y destreza técnica al cirujano (4,10,27) .…”

ResumenObjetivo. Describimos un programa de formación básica en microcirugía y analizamos la curva de aprendizaje a través del proceso, incluyendo la mejora en los tiempos operatorios y en el resultado funcional del procedimiento.Material y métodos. Nuestro programa de aprendizaje incluye modelos básicos, de transición y experimentales. Dentro del modelo experimental se incluyeron: canulación de la vena de la cola, resección y anastomosis intestinal, disección, sección y anastomosis de la cava y la aorta. Se emplearon ratas Wistar (66,7% machos; 406,9 ± 38,9 gramos), el programa se adhirió al principio de las 3R y obtuvo la aprobación del comité de bienestar animal.Resultados. l tiempo medio de canulación de la vena de la cola fue de 2.4 ± 1,2 minutos. El tiempo medio de resección intestinal y anastomosis yeyunocólica de 14.8 ± 2,7 minutos y 10.4 ± 3 minutos, respectivamente. Todas las anastomosis fueron funcionalmente válidas. El tiempo
