Objective assessment of gynecologic laparoscopic skills using the LapSimGyn virtual reality simulator

Abstract

The LapSimGyn VR simulator package demonstrates construct validity on both the basic skills module and the procedural gynecologic module for ectopic pregnancy. Learning curves can be obtained, but to reach the maximum performance for the more complex tasks, 10 repetitions do not seem sufficient at the given task level and settings. LapSimGyn also seems to be flexible and widely accepted by the users.

EVA: Laparoscopic Instrument Tracking Based on Endoscopic Video Analysis for Psychomotor Skills Assessment

“…EVA showed good construct validity both for 2D and 3D metrics. Time, path length, and depth are common parameters, which have been validated in many clinical studies [11,[44][45][46][47][48]. Average speed and acceleration are less widespread metrics, but also showed good discriminative scores [11,44,49].…”

Construct validity of the LapSim virtual laparoscopic simulator within a urology residency program

“…14 They were able to demonstrate a difference between their groups for total time for all tasks and a difference in tissue damage for the lifting and grasping and cutting tasks when they compared the groups after the first and second testing sessions. However, at the tenth testing session, the differences between the various skill levels were no longer statistically significant.…”

“…This is reasonable if we consider that these two parameters are essential for the automatic and immediate assessment they intend to carry out. (Sherman et al, 2005) Yes (Ro et al, 2005) No at the first exposure to simulator (Langelotz et al, 2005) Yes, but time and path metrics only (Hassan et al, 2005) Yes, more patent in second (Eriksen & Grantcharov, 2005) Yes (Woodrum et al, 2006) Yes, but only some parameters (Larsen et al, 2006 …”
