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.

Barrett's adenocarcinoma may occur in multiple sites, and recurrence and metachronous lesions are the major problems with endoscopic resection. Therefore, early detection of such lesions is ideal to achieve complete resection and obtain improved survival rates with minimally invasive treatment. Laser imaging systems allow multiple modalities of endoscopic imaging by using white light laser, flexible spectral imaging color enhancement (FICE), blue laser imaging (BLI), and linked color imaging even at a distant view. However, the usefulness of these modalities has not been sufficiently reported regarding Barrett's adenocarcinoma. Here, we report on a patient with three synchronous lesions followed by one metachronous lesion in a long segment with changes of Barrett's esophagus, all diagnosed with this new laser endoscopic imaging system and enhanced by using FICE and/or BLI with high contrast compared with the surrounding mucosa. Laser endoscopic imaging may facilitate the detection of malignancies in patients with early Barrett's adenocarcinoma.
