The Virtual Rectum: Augmented and Virtual Reality in Colorectal Surgical Learning

A BSTRACT Augmented reality (AR) and virtual reality (VR) are rapidly transforming medical education by providing immersive, interactive, and experiential learning environments. AR overlays digital information onto the real world, while VR creates fully simulated environments that allow learners to engage with complex medical concepts in a safe and controlled setting. These technologies enable the visualization of three-dimensional anatomical structures derived from imaging modalities such as magnetic resonance imaging and computed tomography, improving spatial understanding and knowledge retention compared with traditional two-dimensional learning materials. AR and VR platforms facilitate anatomy learning, surgical simulation, clinical skills training, and interprofessional education. Virtual simulations allow students and trainees to practice procedures, refine technical skills, and develop clinical decision-making without risk to patients. Furthermore, VR-based simulators provide real-time feedback, performance tracking, and haptic interaction, enhancing competency development. Despite challenges such as high cost, technological limitations, and curricular integration, AR and VR hold significant promise for improving accessibility, skill acquisition, and the overall quality of medical education.
