Abstract
Introduction: Live surgery demonstrations have been widely used in surgical education. However, they cannot be used to demonstrate trauma surgery due to the emergency situation and lack of informed consent. The aim of this study was to conduct a live demonstration of trauma surgery with a porcine model to increase educational opportunities in trauma surgery.
Methods: Live demonstration was conducted at the Center for Development of Advanced Medical Technology (CDAMtec) , Jichi Medical University, Japan. An experienced trauma surgeon instructed three trainees during a live demonstration using pre-planned injuries in a porcine model. A six-point Likert Scale was used on a written survey to determine the value of the program to the viewers. Free-form written comments were also obtained from the participants. Live images of the surgical field were transmitted to a lecture room by a closed wireless LAN with interactive bidirectional audio capability.
Results: Eighty-three participants viewed this live demonstration and completed the questionnaire. Participants were highly satisfied with the live demonstration (mean survey scores: 4.6-5.1/6) , and gave very positive feedback concerning the educational value of this program. Nine free-form comments were submitted, which revealed that the participants felt they could acquire concrete skills for trauma surgery.
Discussion: Live demonstrations for trauma surgery using a porcine model are a feasible and effective educational tool to demonstrate technical procedures and non-technical skills, with possible added advantages regarding the ethical considerations of performing a live surgery demonstration.

A live animal training program is offered to medical students seeking more advanced surgical education. This program requires active participation in all aspects, from planning to implementation.　The program provides medical students with a valuable opportunity to develop their interest in surgical care and to acquire advanced surgical techniques through a step-by-step approach. Additionally, they have the chance to develop various types of non-technical skills by assuming different roles within a team. Instructors offer support for their learning.　Peer learning allows medical students to learn from and discuss with each other, enabling them to acquire a broad range of knowledge and skills. Simultaneously, students are expected to understand the importance of a team approach by participating in this program from the perspectives of various medical professions. Moreover, the program contributes to the formation of their professional identity.
