New trainer for video-assisted thoracic surgery lobectomy

Background: Only a few simulators are available which offer training in video-assisted thoracic surgery (VATS). We have developed a VATS training model for surgeons. Methods: The simulator consists of a training module housing three disposable components: the lung (made of polyurethane), the bronchus, and the artificial circulatory pulmonary vessels (made of polyvinyl chloride), connected to a pump. VATS procedures were videotaped and evaluated using a checklist assessment method. Results: This unique module has been tested at several VATS seminars in Japan. In the questionnaire, training participants strongly agreed that the trainer was helpful and prepared them well for VATS lobectomy prior to performing actual surgery. Evaluation of the dexterity score for thoracoscopic surgery with our simulator correlated with the surgeons' experience with actual surgery. Technical factors were well taught using this model. Conclusions: Our unique trainer may enhance the skill of VATS surgeons at a national level.
