Integration and Validation of Hysteroscopy Simulation in the Surgical Training Curriculum
Mohamed Elessawy, Moritz Skrzipczyk, Christel Eckmann-Scholz, Nicolai Maass, Liselotte Mettler, Veronika Guenther, Marion van Mackelenbergh, Dirk O. Bauerschlag, Ibrahim AlkatoutThe primary objective of our study was to test the construct validity of the HystSim hysteroscopic simulator to determine whether simulation training can improve the acquisition of hysteroscopic skills regardless of the previous levels of experience of the participants. The secondary objective was to analyze the performance of a selected task, using specially designed scoring charts to help reduce the learning curve for both novices and experienced surgeons.
Evaluation of the HystSim™-virtual reality trainer: an essential additional tool to train hysteroscopic skills outside the operation theater
Felix Neis, Sara Brucker, Melanie Henes, F. Andrei Taran, Sascha Hoffmann, Markus Wallwiener, Birgitt Schönfisch, Nicole Ziegler, Angelika Larbig, Rudy Leon De WildeMinimally invasive surgery is a major pillar of gynecological surgery. However, there are very few training opportunities outside the operation theater (OR) due to the cost and equipment requirements of organ simulators, virtual reality trainers (VRT) are promising tools to fill this gap.
Advancing Hysteroscopy Skills: Essure® Procedure Virtual Reality Simulator Training
H.W. Schreuder, R.G. Wolswijk, J.E. Persson, I. Ihse, et al.To demonstrate the educational benefits of the Essure® Simulator among physicians seeking to enhance their in-office hysteroscopic skills. The Essure Simulator is a virtual reality-based procedural training platform developed for use on a standard laptop computer. This technology monitors, and realistically simulates, the Essure procedure and offers physicians an innovative teaching opportunity.
A virtual reality simulator for hysteroscopic placement of tubal sterilization micro-inserts: the face and construct validity
J.A. Janse, S. Veersema, F. Broekmans, H.W.R. SchreuderThis study investigated the validity of a virtual reality simulator for hysteroscopic tubal sterilization. Initially performed laparoscopically, the hysteroscopic sterilization method is becoming increasingly popular. An adequate training model could enhance one’s skills prior to the start of performing the procedure on the real patient.
Hysteroscopic Sterilization Using a Virtual Reality Simulator: Assessment of Learning Curve
J.A. Janse, S. Veersema, F. Broekmans, H.W.R. SchreuderThe learning curve is represented by improvement per procedure. Two-way repeatedmeasures analysis of variance was used to analyze learning curves. Effect size (ES) was calculated to express the practical significance of the results (ES R 0.50 indicates a large learning effect). For all parameters, significant improvements were found in novice performance within nine repetitions. Large learning effects were established for six of eight parameters (p , .001; ES, 0.50–0.96). Novices approached expert level within 9 to 14 repetitions. The learning curve established in this study endorses future implementation of the simulator in curricula on hysteroscopic skill acquisition for clinicians who are interested in learning this sterilization technique.
Hysteroscopic Placement of Tubal Sterilization Implants: Virtual Reality Simulator Training
Panel P, Bajka M, Cotin S.Responses to realism, educational potential and general opinion were excellent, proving face validity. Significant differences between novices and experts were assessed for 7 of the 15 metrics analyzed, proving construct validity.
Effectiveness of Simulation Training in Improving the Operative Performance of the Essure® Procedure
Chavan NR, Santandreu O, Jacobs AJ. Dept. of Obstetrics & Gynecology, Flushing Hospital Medical Center, Flushing, New YorkWe prospectively followed two consecutive cohorts of patients undergoing the Essure® procedure over a 1 year period from Feb’11 through Jan’12 - 58 cases before and 78 cases after implementation of the EssureSim™ (VirtaMed AG, Switzerland) simulation program, among residents (n = 14) and attending physicians (n = 44). The time to deployment (time from entering endocervical canal to microinsert placement) was significantly shorter after simulation training, as was the total operating room (OR) time. These cases had a significantly lower frequency of requiring > 2 essure coils for successful insertion.
Evaluation of a New Virtual-Reality Training Simulator for Hysteroscopy
PD Dr. med. Michael Bajka, Dr. Stefan Tuchschmid, Daniel Fink, Prof. Dr. Gabor Szekely, PD Dr. Matthias HardersFace validity has been established for a new hysteroscopic surgery simulator. Potential trainees and trainers assess it to be a realistic and useful tool for the training of hysteroscopy. Further systematic validation studies are needed to clarify how this system can be optimally integrated into the gynecological curriculum.
Establishing Construct Validity of a Virtual-Reality Training Simulator for hysteroscopy via a Multimetric Scoring System
PD Dr. med. Michael Bajka, Dr. Stefan Tuchschmid, Daniel Fink, Prof. Dr. Gabor Szekely, PD Dr. Matthias HardersThe aims of this study are to determine construct validity for the HystSim™ virtual reality (VR) training simulator for hysteroscopy via a new multimetric scoring system (MMSS) and to explore learning curves for both novices and experienced surgeons.
Preliminary Experience with Virtual Reality Simulation vs. Animal Model for Hysteroscopic Myomectomy Training
L.R. Glazerman, S.R. Hart, M. Bajka, D. Fink, R.R. BassalyThe HystSim™ Virtual Reality hysteroscopic trainer was felt to be at least equal to the ‘‘gold standard’’ pig bladder model for training in hysteroscopic myomectomy with the additional advantages of reproducibility and measurement of results. Further studies comparing modalities and relating results to operating room performance are warranted.
Reference Center HELIOS hospital group, GermanyThe HELIOS Hospital Group consists of 110 acute and rehabilitation facilities with about 34.000 beds and more than 69.000 employees. The departments for urology and gynecology train a large group of residents each year until they complete their education as medical specialists. In 2011, HELIOS included VirtaMed's virtual reality simulators into their standard curriculum for residents in training. E.g. in each urology department, a simulator is placed at the disposal of each clinic for six weeks each year. During this time, the head physician conducts a training program. In his or her first year, every surgeon who wants to conduct transurethral resection has to perform 50 documented procedures on the simulators.
