    In this paper, the development of an assisting system for laparoscopic surgical training is presented. With this system, we expect to facilitate the training process at the first stages of training in laparoscopic surgery and to contribute to an objective evaluation of surgical skills. To achieve this, we propose the insertion of multimedia contents and outlines of work adapted to the level of experience of trainees and the detection of the movements of the laparoscopic instrument into the monitored image. A module to track the instrument is implemented focusing on the tip of the laparoscopic tool. This tracking method does not need the presence of artificial marks or special colours to distinguish the instruments. Similarly, the system has another method based on visual tracking to localize support multimedia content in a stable position of the field of vision. Therefore, this position of the support content is adapted to the movements of the camera or the working area. Experimental results are presented to show the feasibility of the proposed system for assisting in laparoscopic surgical training

    Las técnicas laparoscópicas se han convertido en patrón oro en muchos procedimientos quirúrgicos, pero implican un proceso de adquisición de destrezas más complejo que en el caso de la cirugía abierta. En esta fase formativa, los simuladores virtuales tienen un papel muy importante puesto que permiten evaluar de forma objetiva la ejecución de una tarea quirúrgica mediante la extracción automática de métricas. Este trabajo de investigación presenta un análisis de las métricas calculadas por el simulador virtual SINERGIA con el fin de poder llevar a cabo una evaluación objetiva de las destrezas laparoscópicas básicas
