Study Objective To evaluate the Essentials in Minimally Invasive Gynecology (EMIG)- Fundamentals of Laparoscopic Surgery Laparoscopic Simulation System and the EMIG Hysteroscopy Simulation System for face validity and functionality in a pilot testing environment. Design A prospective controlled pilot study. Setting Three teaching institutions in the US Southwest. Subjects Twenty-seven residents and gynecologists, with 22 fitting who fit 1 of 4 categories of exposure to hysteroscopic and laparoscopic surgery and surgical simulation. Eleven were postgraduate year 1 and 5 postgraduate year 3, 1 was American Board of Obstetrics & Gynecology certified, and 5 were either fellows in-training or had completed a fellowship in minimally invasive gynecologic surgery. Interventions After completing a screening survey, each subject was exposed to a structured orientation to the 2 simulation systems and then tested with proctor supervision on the 5 laparoscopic and 2 hysteroscopic exercises. A short 5-point Likert questionnaire designed to determine face validation and question clarity was administered to each subject at sites 2 and 3. Measurements and Main Results Face validity was high for each of the 7 exercises (means ranged from 4.8 to 4.9 of 5), and subjects considered instructions to be clear (means from 4.7 to 4.9). The recorded exercise times generally reduced with increasing levels of training, although the sample sizes were not designed to determine significance given the pilot design. Similarly, exercise errors were generally less frequent with increasing experience. The systems, including the devices and recording mechanisms, performed well, and proctor evaluation and training were satisfactory. Conclusion The EMIG laparoscopic and hysteroscopic simulations systems were considered to have good face validity and appear to be suitable for a construct validation trial to confirm their utility in distinguishing among trainees and practitioners with a wide spectrum of endoscopic surgical experience. The recording and specimen storage mechanisms will allow for multiple proctors to rate a candidate's performance, thereby enhancing evaluation consistency and quality.
