This study examines the influence of monoscopic vs. stereoscopic visualization in novice trainees performing the MISTELS, a validated laparoscopic skill evaluation system consisting of 5 distinct tasks. We hypothesize a difference in performance based on visualization modality. First and second year medical students (n=31) performed the MISTELS battery of tasks using either monoscopic or stereoscopic visualization displays. Regression analysis indicates performance was not correlated to participant manual dexterity or visual spatial ability (p>;0.05). Monoscopic visualization was shown to produce significantly better performance in the peg transfer task alone (p=0.001), with visualization modality producing no significant difference in performance of the remaining tasks (p>;0.05). Qualitatively, 57.1% of participants believed their performance was aided by stereoscopic visualization. Most participants rated the peg transfer task the least difficult task (60%), and the intracorporeal knot‐tying task the most difficult (65.9%). These results suggest the intrinsic difficulty of the MISTELS tasks may exceed a novice user's skill, rendering no benefit with additional 3D cues in naïve surgical trainees, and may serve to increase cognitive load, potentially decrease skill acquisition and learning.
