What is Laparoscopic Ambidexterity in Left-Handed Trainees about?

## Introduction: There is a paucity of objective data about the advantages or disadvantages of handedness in surgery. given the need for ambidexterity in laparoscopic surgery, our study aimed to identify the patterns in handedness and performance on basic laparoscopic tasks. ## Methods: A retrospective analysis of intern laparoscopic performance on bimanual tasks was assessed for delta time (differences in task time between the dominant and nondominant hand) between left-hand and right-hand dominant interns. ## Results: Data were analyzed for 16 residents. 25% were left-handed dominant (4/16) and 75% were right-handed dominant (12/16). of the left-handed surgeons, 75% (3/4) operated primarily with their right hand. there was a significant difference between the time to task completion in task 2 of left-handed and right-handed residents with median (iqr) time 94 s (90.25-97) and 127 s (104.25-128.5), respectively (p value = 0.02). no significant difference was seen between left-handed and right-handed residents on task 1 (50 s versus 49 s) and task 3 (51 s versus 59.5 s). in all three tasks, however, left-handed dominant residents had smaller variability (iqr 4.5-8 s versus 7-24.25
