INTRODUCTION: Simulated laparoscopy training is limited by its low-quality image. A high-definition (HD) laparoscopic training box was developed under the present necessity of simulating advanced surgery. OBJECTIVE: To describe and test a new HD laparoscopic training box for advanced simulation training. METHODS: We describe the features and image quality of the new training box. The simulator was tested and then evaluated by a group of 76 expert surgeons using a 4-item questionnaire. To assess the effectiveness of training using this simulation box, 15 general surgery residents were trained to perform a laparoscopic jejuno-jejunostomy in a validated simulation program. They were assessed with objective rating scales before and after the training program, and their results were compared with that of experts. RESULTS: The training box was assembled using high-density fiberglass shaped as an insufflated abdomen. It has an adapted full-HD camera with a LED-based illumination system. A manually self-regulated monopod attached to the camera enables training without assistance. Of the expert surgeons who answered the questionnaire, 91% said that the simulation box had a high-quality image and that it was very similar to real laparoscopy. All residents trained improved their rating scores significantly when comparing their initial versus final assessment ( P < .001). Their performance after completing the training in the box was similar to that of experts ( P > .2). CONCLUSIONS: This novel laparoscopic training box presents a high-resolution image and allows training different types of advanced laparoscopic procedures. The simulator box was positively assessed by experts and demonstrated to be effective for laparoscopy training in resident surgeons.
