Open Lobectomy Simulator Is an Effective Tool for Teaching Thoracic Surgical Skills

Simulation has long been appreciated and used in professional industry training. The effectiveness of high-fidelity, low-cost simulators in such settings has led to its integration into surgical education for skill development. Simulation may possibly have a role in surgical specialty training. Replicas of a human torso with a posterolateral thoracotomy incision were constructed from poultry netting and casting fiberglass, and used to house a previously prepared bovine lung. After reviewing computerized instructional material, student volunteers were asked to perform a lobectomy with the assistance of a thoracic surgeon, who also evaluated the subjects. Objective data were collected from knowledge-based examinations and technical skills evaluation scales. Statistical analysis was performed with the Student's t test. The initial success rate was 88.9% (16 of 18). Significant improvements were appreciated in both subjective and objective measures by the third week with weekly repetition. The average operative time was reduced to 34.8 +/- 5 minutes from 48.5 +/- 4.9 minutes (p = 0.01). The average task-specific score was 7.8 +/- 0.8 (versus 5.6 +/- 2.1; p = 0.05), and students achieved an average global performance score of 28.6 +/- 3.8 (p = 0.01). Scores on knowledge-based examinations also significantly improved. This open lobectomy simulation can be used to effectively teach thoracic surgery techniques. Our results prove the effectiveness of simulation training in thoracic surgery. Additional studies will determine whether simulation is effective for different training levels in thoracic surgery.

Computer-Based Simulation Training in Surgery

Computer-based simulation training methods have emerged in mainstream residency training in response to evolving educational demands. These methods include surgical virtual reality (VR), computer driven full patient simulation, and screen-based simulations, of which immersive virtual environments reflect the most recent area of development. Over a single decade, surgical VR has progressed from demonstration of concept to a practical training tool, with a body of validation literature for part-task VR trainers that supports their expanded use, as well as the development of more robust and capable systems to satisfy the need for procedural training. Patient simulation is gradually entering surgical residency training for crisis resource management and team training that might not otherwise be feasible outside clinical settings. In the future, simulation of patient care in virtual environments may constitute a similar experience without the resource demands associated with full patient simulation. Collectively, the use of computers to create simulated learning experiences for surgeons is representative of an experiential learning model that has been far more developed in other undertakings, but which will certainly be more relied on in surgical training in the future.

Simulation training in video-assisted urologic surgery

The current system of surgical education is facing many challenges in terms of time efficiency, costs, and patient safety. Training using simulation is an emerging area, mostly based on the experience of other high-risk professions like aviation. The goal of simulation-based training in surgery is to develop not only technical but team skills. This learning environment is stress-free and safe, allows standardization and tailoring of training, and also objectively evaluate performances. The development of simulation training is straightforward in endourology, since these procedures are video-assisted and the low degree of freedom of the instruments is easily replicated. On the other hand, these interventions necessitate a long learning curve, training in the operative room is especially costly and risky. Many models are already in use or under development in all fields of video-assisted urologic surgery: ureteroscopy, percutaneous surgery, transurethral resection of the prostate, and laparoscopy. Although bench models are essential, simulation increasingly benefits from the achievements and development of computer technology. Still in its infancy, virtual reality simulation will certainly belong to tomorrow's teaching tools.
