Résumé
The study involves the testing of a novel laparoscopic training model by surgeons of various levels of experience. 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. 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). Ninety-five 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 < 0.0001) and intermediates (58/80 vs 29.1/80; p = 0.0004), and intermediates scored higher than novices (29.1/80 vs 11.7/80; p = 0.014). Novices took more time to complete the task compared to intermediates (10 min vs 7.87 min; p < 0.0001) and experts (10 min vs 6.98 min; p < 0.0001). No correlation between time taken and score obtained was seen (r = -0.06, r = 0.01, r = -0.2 for novice, intermediate, and expert groups). By differentiating between groups of variable experience, the model demonstrated construct validity. It offers an inexpensive model that can be utilized in low-cost laparoscopic simulation.

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
Ninety-five 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 < 0.0001) and intermediates (58/80 vs 29.1/80; p = 0.0004), and intermediates scored higher than novices (29.1/80 vs 11.7/80; p = 0.014). Novices took more time to complete the task compared to intermediates (10 min vs 7.87 min; p < 0.0001) and experts (10 min vs 6.98 min; p < 0.0001). No correlation between time taken and score obtained was seen (r = -0.06, r = 0.01, r = -0.2 for novice, intermediate, and expert groups).
CONCLUSION
CONCLUSIONS
By differentiating between groups of variable experience, the model demonstrated construct validity. It offers an inexpensive model that can be utilized in low-cost laparoscopic simulation.
