Participants (n = 124) included medical students, residents, fellows, and attending surgeons from general surgery, gynecology, and urology in 3 Canadian universities. They were classified in groups based on laparoscopic experience: novice, intermediate, competent, and expert. Participants (n = 124) were tested on the LTS, and 74 were tested on both the LTS and the MISTELS. A user satisfaction questionnaire was completed after each performance.
LTS metrics showed a progressive improvement in total scores according to academic level as well as level of laparoscopic experience (P < .001). Good correlation was found between the LTS and the MISTELS (r = .79). Level of user satisfaction was highest with LTS.
Based on laparoscopic experience and academic level, the LTS has a comparable discriminating capability for level of performance with that of the MISTELS. The higher degree of user satisfaction attributed to the LTS could justify its use as a training and assessment tool for surgical specialties.
