Colorectal cancer is one of the most common cancers in the United States. Endoscopic Submucosal Dissection (ESD) is an emerging minimally invasive technique that allows complete en-bloc resection and a much lower recurrence rate at long-term follow-ups. However, performing colorectal ESD is technically demanding since the colorectal wall is thin and constantly moving, and potentially higher rates of complications (e.g., bleeding and perforations), and there is lack of a sufficient number of expert instructors for ESD training in Western countries. One approach to reducing this gap is to design an ESD surgical simulator as part of a training curriculum. The aim of our study is to design a virtual endoluminal surgical simulator with visual and haptic feedback along with assessment metrics based on a cognitive task analysis (CTA) approach. The simulator allows trainees to attain competence in a controlled environment with no risk to patients and can assess the trainees’ performance. Training tasks are built based on physics-based computational models of human anatomy with tumors. I will present a CTA-based approach to design a virtual ESD simulator that involves high-fidelity anatomical organ modeling, physics-based tool-tissue interactions, and performance metrics.
