Aims: The primary aim of this study was to compare the performance of surgical novices using an articulating
laparoscopic needle holder (FlexDex®) against standard non-articulating laparoscopic needle holders. The
secondary aim was to explore participant�??s perception on instrument ergonomics by means of subjective surveys.
Methods: This was a prospective randomized cohort study. Medical students (n=40) with no previous
laparoscopic experience were randomized into Group-1 (n=20) which used standard instruments or Group-2
(n=20) which used the FlexDex®. Both groups performed 10 repetitions of a validated assessment task. Times
taken and error rates were measured.
Results: Following 10 attempts, Group-1 demonstrated a mean time of 217.9 seconds and mean error rate of
6.2, while Group-2 showed a mean time of 339.3 seconds and mean error rate of 9.3. There was a statistically
significant difference in the mean times (P<0.001) and error rates (P<0.010).
Conclusion: Participants using the FlexDex®demonstrated inferior performance compared to the group
utilizing standard laparoscopes. Overall, both groups showed improved mean times after each attempt, which
illustrated a learning experience. These results may indicate a longer or more challenging learning curve
associated with the FlexDex® in novel users.
