Imagine a surgeon could rehearse a delicate liver or pancreas operation on a perfect replica of your body before you ever go under the knife. A new review examines three high-tech training tools that aim to make this possible. It finds that 3D-printed models offer an incredibly realistic feel of a patient's unique anatomy, but they can't simulate how living tissue behaves. Virtual reality lets surgeons practice a procedure over and over in a risk-free digital space, but the sense of touch isn't quite real yet. Augmented reality projects holographic guides into the real surgical field, helping bridge planning and action, though it can be mentally overwhelming for the surgeon. It's crucial to understand this is a narrative review—it describes the characteristics of these emerging tools but doesn't provide any data on whether they actually lead to better surgeons or safer operations. The authors point out that future work needs to prove these simulations translate to real-world skill.

This narrative systematic review synthesizes advancements in simulation-based training modalities for laparoscopic hepatobiliary and pancreatic surgery. The review describes characteristics of three technologies: three-dimensional printing provides tactile fidelity for patient-specific anatomy replication but lacks dynamic physiological responses; virtual reality enables risk-free procedural repetition and AI-driven skill optimization but struggles with haptic authenticity; augmented reality bridges preoperative planning and intraoperative execution through real-time holographic navigation but faces challenges in cognitive load management.
No quantitative outcomes, effect sizes, or comparative effectiveness data are reported. The review does not include patient or trainee outcomes, validation data for transfer-to-practice metrics, or information about study populations, sample sizes, or follow-up periods. Safety and tolerability data are not reported.
Key limitations include the narrative nature of the review without quantitative synthesis or certainty assessment. The authors note that future advancements should prioritize hybrid simulation ecosystems integrating biomechanical realism with adaptive virtual interfaces, validated transfer-to-practice metrics, and ethical frameworks for emerging technologies.
For clinical practice, this review provides a descriptive overview of technological characteristics but offers no evidence regarding the effectiveness of these simulation modalities for improving surgical skills or patient outcomes. The findings should be interpreted cautiously as they represent a synthesis of technological features rather than validated training outcomes.
