Abstract No. 387: Simulation training in percutaneous image-guided interventions

Abstract

Users will gain familiarity with key technical aspects and necessary steps required for percutaneous image-guided interventions, namely the placement of an abscess drainage catheter. Current limitations in resident work hours, though essential for physician health and decision-making, has unfortunately resulted in decreased hands on procedural and operative experience. This paradigm shift has resulted in the need for accurate simulation modules to allow the training physician to both learn the steps of procedures as well as develop comfort in its technical aspects. We have developed a software application that simulates the sequential steps required for percutaneous image-guided interventions. The program was written in the Adobe Flash environment to construct an interactive graphical display interface (GUI) to enhance the user experience. Our training module simulates the deployment of a CT-guided drainage catheter. Briefly, a video of an actual abscess drainage case was recorded after obtaining patient consent. The video was subsequently edited and imported into our software program, which also utilizes a list of images that a user can select from the computer screen. Each image, which represents a key step in the procedure, is temporally synchronized to its appropriate position in the video. For instance, an image of a biopsy grid may be associated with video playback demonstrating the technique of localizing proper site of percutaneous access. The list of images is randomized, and the simulation will only proceed forward if the end user selects the correct chronologic sequence of steps. Lastly, a narrative is provided throughout the video to provide more details on each step. Simulation technologies play an integral role in medical training and practice. We have developed a training module that simulates the sequential steps required in the placement of a CT-guided percutaneous drainage catheter.
