Brief Summary

The aim of this study is to find out whether basic laparoscopic skills training (FLS tasks) on a standard pelvic trainer using conventional 2D visualization is at least equally effective in terms of skills improvement compared to practicing with 3D visualization. Furthermore, the progress in basic laparoscopic skills improvement for each visualization modality will be analyzed.

Detailed Description

An increasing number of operations are done minimal invasively. For example, appendectomy, cholecystectomy, bariatric procedures, colorectal resections as well as hysterectomy and many other gynecologic procedures, are routinely performed laparoscopically.

Laparoscopy requires psychomotor skills that may be difficult to learn and result in prolonged learning curves. In order to become familiar with the 2-dimensional visualization and to learn and improve laparoscopic skills, training is needed. As traditional training in the operating room is expensive and comprises an increased operating risk for the patient, various training alternatives outside the operating room have been developed and shown to be effective in translating the thereby acquired skills to the operating room. Besides training on live animals or cadavers, there are virtual reality simulators, augmented reality simulators and different box trainers. Each of these training devices has specific advantages and limitations. However, some types could be superior to others in terms of training effectiveness. For instance, with implementation of 3D visualization during laparoscopic interventions which facilitates spatial perception, the question arises as to whether training of basic laparoscopic skills using conventional 2D visualization is at least equally effective compared to training with 3D visualization.
