Virtual pelvic anatomy and surgery simulator: an innovative tool for teaching pelvic surgical anatomy.
Pelvic three-dimensional (3-D) anatomy is complex and can be difficult to visualize. We have developed an alpha-version virtual anatomic model that will facilitate a) student learning of anatomy b) resident preparedness for operation, c) surgical planning for complex, multidisciplinary procedures. This educational module is composed of the virtual anorectum, an anatomically accurate, interactive model of the anorectum and pelvic viscera based on co-registered human computed tomographic (CT) and magnetic resonance (MR) images. It also consists of a physical model fabricated from the same data-set using stereolithography. Usability and functionality was assessed in a sample of surgical trainees. Feedback demonstrated that the module is an efficient adjunct to medical education and surgical planning. Ultimately, we envision a deformable virtual model that allows residents and surgeons to rehearse complex surgical procedures by performing virtual surgery, thereby improving preparedness for real operations. Such a model will be integrated into a colorectal surgery educational curriculum, and in the future may represent a unique method of competency testing.
