“…The growing practice of laparoscopy and minimally invasive surgery (MIS) in small [1,2] and large animals [3,4] has uncovered two critical facts: first, MIS requires prior simulation using appropriate models for the acquisition of basic, advanced, and specific skills for each surgery; and second, even though there are simulators for deliberate practice [5], there are not enough devices on which to train and perform the minimum simulation required to acquire the skills necessary to perform a given surgery [6]. Training for the acquisition of basic and advanced skills needs reliable devices in which the skills required to complete the actual procedure can be transmitted to the operating room [7][8][9], reducing the risks for the real patient and a curriculum supporting the training schedule [9].…”

This study aims to assess the acquisition of surgical skills for laparoscopic ovariectomy (LOE) in dogs by veterinary surgeons with no experience in minimally invasive surgery using the CALMA Veterinary Lap-trainer simulator (CVLTS) in an experimental and analytical setting. Veterinary surgeons with no experience in minimally invasive surgery (MIS) (experimental, n = 5), and MIS experts (experts, n = 3) were evaluated. Experimental and expert group participants watched an instructional video (initial time) before practicing the LOE on uterine tissues and ovaries freshly reconstituted after elective ovariohysterectomy (initial time evaluation). Then, the experimental group practiced five training sessions on the composite simulator with permanent feedback and then performed the LOE again (final time evaluation). Surgical performances in initial and final evaluations were video recorded and further evaluated by three external MIS experts using Global objective assessment of laparoscopic skills (GOALS) and LOE-specific rating scales (SRSs) in a double-blinded schedule. In addition, a hands movement assessment system (HMAS) attached to the back of the hands was used to quantitatively measure completion time, angularity, and movement smoothness. Data were analyzed with one-factor ANOVA and Tukey’s contrast test. No statistically significant differences were found between the novice group’s performance after training and the expert group’s performance according to the GOALS (p < 0.01) and SRS (p < 0.05) scores. Moreover, the novices had significantly improved time, number of movements, and angularity in the final time compared with the initial time (p < 0.05), with no significant differences compared to the expert group (p > 0.05). LOE training using a composed simulator resulted in significantly improved laparoscopic skills and time, number, and angularity of movements data, providing evidence of the usefulness and reliability of CVLTS in training LOE.
