Colecistectomía laparoscópica por un solo puerto. Modelo ex vivo de entrenamiento / Laparoendoscopic single site surgery (less) cholecystectomy. Ex vivo training model

Objetivo: Describir un modelo ex vivo de entrenamiento para colecistectomía laparoscópica mediante abordaje por una sola incisión (LESS). Método: Se utilizó el complejo hepatobiliar ex vivo del Sus scrofa domesticus, los cuales fueron colocados en cajas negras convencionales, se tomó en cuenta si el modelo era capaz de permitir las prácticas de cada uno de los pasos del procedimiento. Se determinó el impacto de la práctica en la superación de dificultades al evaluar el desempeño de dos cirujanos en cinco sesiones consecutivas, teniendo como parámetro el tiempo empleado en completar la tarea. Resultados: En el modelo descrito es posible reproducir cada uno de los pasos de la colecistectomía laparoscópica a través de una sola incisión, permitió a los residentes la práctica y superación de dificultades propias de la técnica, lo cual se hizo evidente con la disminución del tiempo empleado. Conclusión:El modelo propuesto permite el entrenamiento del equipo quirúrgico en colecistectomía laparoscópica mediante abordaje por una sola incisión(AU)

Objective: To describe an ex vivo model for training LESS cholecystectomy. Method: The hepatobiliary complex of Sus scrofa domesticus placed in conventional "black boxes" was used. The capability of the model to allow practice of each step of the procedure was evaluated. We determined the impact of the practice in overcoming technical difficulties assessing the performance of two surgeons in five consecutive sessions, the time required to complete de task was evaluated. Results: It is possible to perform each step of LESS cholecystectomy in the proposed training model. It allows post-graduate residents practice and overcoming related difficulties.Conclusion: The proposed training model allows the practice of LESS cholecystectomy(AU)

ESD Hands-on Course Using Ex Vivo and In Vivo Models in South Korea

Endoscopic submucosal dissection (ESD) is an established treatment for gastric neoplasias especially in regions with a high volume of gastric cancer. Although ESD has many advantages over endoscopic mucosal resection, ESD is technically more difficult and can result in severe complications. Therefore establishment of an effective training system is required to help endoscopists climb the ESD learning curve. Although a standard training system for ESD remains to be established, some centers are incorporating ex vivo and/or in vivo animal models to provide a safe and effective means of ESD training. However, it is unknown if these animal models are more effective than other programs. Moreover the efficacy of the animal model may vary according to socio-economic status and the volume of gastric cancer. In this article we introduce the basic and advanced ESD training model using the ex vivo and in vivo animal model from South Korea and review the associated literature from other regions.
