    Lobectomía video-asistida por puerto único utilizando un nuevo modelo de simulación ex vivo perfundido
    (2016) Ávila Sepúlveda, Rubén; Achurra Tirado, Pablo; Tejos, Rodrigo; Varas Cohen, Julián; Solovera Rozas, María; Salas Villarroel, Patricio; Pontificia Universidad Católica de Chile. Escuela de Medicina
    La simulación puede proporcionar una solución para adquirir habilidades avanzadas en cirugía torácica, sin embargo, hasta la fecha de publicación de este artículo no hay informes sobre un modelo ex vivo perfundido. Desarrollamos un modelo de bajo costo y alta fidelidad utilizando una muestra ex vivo en bloque de corazón y pulmón de un cerdo. El cerdo se usó previamente en un experimento no torácico, por lo que extrajimos el pulmón y el corazón para este modelo basado ex-vivo para reducir el uso de animales. El costo del modelo completo es de 70 USD y se puede reutilizar muchas veces cambiando el tejido ex vivo, por lo que este modelo puede ayudar a reducir los costos y el uso de animales asociados a esta cirugía de alta complejidad.

    MicrosimUC: Validation of a Low-Cost, Portable, Do-It-Yourself Microsurgery Training Kit
    (2021) Navia, Alfonso ; Tejos, Rodrigo ; Canahuate, Sebastian ; Machuca, Eduardo ; Searle, Susana ; Cuadra, Alvaro ; Dagnino, Bruno
    Background Microsurgery depends largely on simulated training to acquire skills. Courses offered worldwide are usually short and intensive and depend on a physical laboratory. Our objective was to develop and validate a portable, low-cost microsurgery training kit.

    Video-based guided simulation without peer or expert feedbackis not enough : a randomized controlled trial of simulation based training for medical students
    (2021) Tejos, Rodrigo; Crovari Eulufi, Fernando; Achurra Tirado, Pablo; Ávila, Rubén; Inzunza, Martín; Jarry, Cristián; Martínez C., Jorge; Riquelme Pérez, Arnoldo; Alseidi, Adnan; Varas, Julián
    Background Feedback is a pivotal cornerstone and a challenge in psychomotor training. There are different teaching methodologies; however, some may be less effective. Methods A prospective randomized controlled trial was conducted in 130 medical students to compare the effectiveness of the video-guided learning (VLG), peer-feedback (PFG) and the expert feedback (EFG) for teaching suturing skills. The program lasted 4 weeks. Students were recorded making 3-simple stitches (pre-assessment and post-assessment). The primary outcome was a global scale (OSATS). The secondary outcomes were performance time, specific rating scale (SRS) and the impact of the intervention (IOI), defined as the variation between the final and initial OSATS and SRS scores. Results No significant differences were found between PFG and EFG in post-assessment results of OSATS, SRS scores or in the IOI for OSATS and SRS scores. Post-assessment results of PFG and EFG were significantly superior to VLG in OSATS and SRS scores [(19.8 (18.5–21); 16.6 (15.5–17.5)) and (20.3 (19.88–21); 16.8 (16–17.5)) vs (15.7 (15–16); 13.3 (12.5–14)) (p \0.05)], respectively. The results of PFG and EFG were significantly superior to VLG in the IOI for OSATS [7 (4.5–9) and 7.4 (4.88–10) vs 3.5 (1.5–6) (p \0.05)] and SRS scores [5.4 (3.5–7) and 6.3 (4–8.5) vs 3.1 (1.13–4.88) (p \0.05)], respectively. Conclusion The video-guided learning methodology without any kind of feedback is not enough for teaching suturing skills compared to expert or peer feedback. The peer feedback methodology appears to be a viable alternative to handling the emerging demands in medical education.
