Evaluation of a Novel Low-Cost Laparoscopic Training Model for Core Laparoscopic Skills

Abstract The study involves the testing of a novel laparoscopic training model by surgeons of various levels of experience. Type of Study: Study of a diagnostic test Level of Evidence: II Background There has been an increasing requirement for low-cost simulation. Our aim was to evaluate the construct validity of a low-cost model for teaching core laparoscopic skills. Methods The Double-Glove model was made from 2 latex gloves, one placed in the other. The inner glove was filled with water and 3 ovals were drawn on the outer glove. Participants were required to dissect the middle oval out without perforating the inner glove or leaving the line border of the middle oval. The task was assessed using a previously validated scoring system (minimum -120; maximum 80). Results 95 participants completed the task: 40 novices, 45 intermediates, and 10 experts. The model revealed statistical significance between the three groups. Experts scored higher than novices (58/80 vs 11.7/80; p  Conclusion By differentiating between groups of variable experience, the model demonstrated construct validity. It offers an inexpensive model that can be utilised in low-cost laparoscopic simulation.
