[Evidence, Availability and Future Visions in Simulation in General and Visceral Surgery].

Practice makes perfect - a saying that everyone has certainly heard. Surgeons of all levels of training can demonstrably practice to some extent on simulators. This training outside the operating theatre and independent of patients makes sense, both ethically and financially. Although the effectiveness of simulation in surgery has been proven several times, simulation training is not a mandatory part of surgical specialist training in Germany. Simulation covers a very wide range in terms of application, effort and costs. This review is intended to give an overview of the systems and their areas of application and the target group. The focus lies on the commonly available systems and possible advantages and disadvantages. Practical skills are in the foreground and all three pillars of general and visceral surgery - conventional techniques, laparoscopy and robotics - are taken into account. However, simulators alone do not achieve cost-benefit effectiveness. The full potential of such an investment can only be exploited with a site-specific, structured training concept in which simulation training according to the post-graduate year and appropriate allocation to surgeries in the operating room are closely interlinked. It should always be possible to train basic skills on site. The significant additional costs for complex simulation systems are possible, depending on the financial resources, or should be purchased in a network or for national courses. The techniques of immersive virtual reality in combination with artificial intelligence and deformation algorithms will certainly play a decisive role for the future of simulation, whereby the use of the available systems must be a primary goal. The integration of simulation into specialist training should be striven for, not least in order to justify the costs.
Competing Interests: Tobias Huber has a non financial research cooperation regarding simulation in laparoscopic camera navigation with Surgical Science Sweden. Tobias Huber receives funding from BMBF, DFG, UM Mainz, Liver Foundation, Gutenberg Lehrkolleg Mainz, Alexander Karl Stiftung Mainz. Florentine Hüttl receives funding from the German Society of Surgery. Peter Grimminger is a Proctor for Intuitive Surgical. Hauke Lang, Laura Hanke, Lukas Vradelis and Nils Sommer declare no conflict of interest. Shown Simulators have been supported by intramural educational funding of the university medical center Mainz and Alexander Karl-Stiftung, Mainz, Germany.
