Original Contributions



To determine the physical and mental impact on the primary surgeon, by the patient’s and surgical staff’s dispositions at the operating table, during laparoscopic vertical sleeve gastrectomy.

Materials and Methods

This is a randomized and controlled study that included 18 laparoscopic sleeve gastrectomy procedures performed by two surgeons in a private and academic hospital. The cases were randomized for the American or French position. After surgery, the National Aeronautics and Space Administration - Task Load Index (NASA-TLX) and the Body Part Discomfort (BPD) scales were applied to the primary surgeon.


An increased workload and more discomfort were reported when using the French position. The NASA-TLX was 28 ± 8 vs. 57 ± 18 (p = 0.001), and the BPD was 2 vs. 8 (p = 0.001).


The American position resulted in a lower physical and mental impact on the surgeon when performing a laparoscopic sleeve gastrectomy.
