“…Some authors have demonstrated that box trainers are an effective alternative to virtual reality simulators, demonstrating that they have equal or better didactic effect when compared to virtual reality simulators [23][24][25][26]. Amongst other arguments, it has also been suggested that haptic feedback in VRS may not be as realistic as the one provided by box trainers [27].…”

Background: Practice on Virtual Reality simulators (VRS) have been shown to improve surgical performance. However, VRS are expensive and usually housed in surgical skills centres that may be inaccessible at times convenient for surgical trainees to practice. Conversely, box trainers are inexpensive and can be used anywhere at anytime. This study assesses "take-home" Box Trainers (BT) as an alternative to VRS.Methods: After baseline assessments (two simulated laparoscopic cholecystectomies, one on a VRS and one on a BT) 25 surgical trainees were randomised to two groups. Trainees were asked to practice 3 basic laparoscopic tasks for 6 weeks (BT group using a "take-home" box trainer; VR group using VRS in clinical skills centres). After the practice period all performed two LC, one on a VRS and one on a BT; (i.e. post-training assessment). VRS provided metrics (total time (TT), number of movements (NOM) instrument tip path length (PL)) and expert video assessment of cholecystectomy in a BT (GOALS score) were recorded. Performance during pre-and post-training assessment was compared.Results: The BT group showed a significant improvement for all VRS metrics (p=0.008) and the efficiency category of GOALS score (p=0.03). Only TT improved in the VRS group and none of the GOALS categories demonstrated a statistically significant improvement after training.

IntroductionLaparoscopic trainers have gained recognition for improving laparoscopic surgery skills and preparing for operations on humans. Unfortunately, due to their high price, commercial simulators are hard to obtain, especially for young surgeons in small medical centers. The solution might be for them to construct a device by themselves.AimTo make a relatively cheap and easy to construct laparoscopic trainer for residents who wish to develop their skills at home.Material and methodsTwo laparoscopic simulators were designed and constructed: 1) a box model with an optical system based on two parallel mirrors, 2) a box model with an HD webcam, a light source consisting of LED diodes placed on a camera casing, and a modeling servo between the webcam and aluminum pipe to allow electronic adjustment of the optical axis.ResultsThe two self-constructed simulators were found to be effective training devices, the total cost of parts for each not exceeding $100. Advice is also given for future constructors.ConclusionsHome made trainers are accessible to any personal budget and can be constructed with a minimum of practical skill. They allow more frequent practice at home, outside the venue and hours of surgical departments. What is more, home made trainers have been shown to be comparable to commercial trainers in facilitating the acquisition of basic laparoscopic skills.

“…Virtual trainer was primarily a measurement tool but was not determinating the effectiveness of training [20]. A similar approach was presented by other authors, who recognized the measuring value of virtual trainers, but they questioned the practical advantages due to the still insufficient scope of reflecting reality in virtual circumstances [21].…”

IntroductionSurgical education has become one of the most important directions in modern surgery evolution. To meet growing need for appropriate training in laparoscopic and, even more importantly, classic surgical skills, a curriculum involving contemporary tuition methods is needed. Advanced, structuralised training, which includes advanced technologies like virtual reality training, video coaching and motivative aspects of competition, seems to be important for an adequate education programme.Material and methodsIn academic years 2009/2010 and 2010/2011 the Department of General, Endocrine and Transplant Surgery of the Medical University of Gdansk together with the Pomeranian Foundation for Progress in Surgery organized 4480 h of training in that area of classic (2744) and laparoscopic (1736) skills. Both groups were involved in the programme of training in which the two most important aspects were reliable evaluation of the results and effective motivation to work. Skill evaluation at different stages of the programme were based on completion time and quality measurements. Apart from that, at the end of the course, the participants completed a questionnaire on their subjective perspective on this innovative curriculum, the quality and stability of the skills they obtained.ResultsIn both arms of the programme (laparoscopic and classic) a statistically significant improvement was obtained as early as after the second and third sessions in half of the exercises. The acquired skills were stable over time, as proved by the plateau of completion time achieved in 11 out of 12 exercises. The results of the post-training questionnaire revealed that the participants were very satisfied with the structuralised form of training and appreciated the motivational role of competition.ConclusionsContemporary surgical training should be organized as a systematic, well-evaluated and goal-oriented programme similar to the one proposed by our team. The use of contemporary training aids should be utilized in training of every surgical skill, not only laparoscopy. This form of training, associated with the component of competition, enables good and stable results to be achieved, as well as high satisfaction of trainees.
