Background:
Standard laparoscopy (SL) is responsible for musculoskeletal disorders in surgeons because of poor ergonomic positions, which could be reduced by robot-assisted laparoscopy (RAL) owing to the surgeons' seated position. One of the aims of the ROBOGYN-1004 study (NCT01247779) was to evaluate surgeons' workloads during real-time procedures of gynecological oncological surgery.
Methods:
Patients with gynecological cancer eligible for minimally invasive surgery were recruited from 13 French centers between December 2010 and December 2015. Physical workload was evaluated using the Borg scale every hour over the surgery duration and the perception of workload evaluated using NASA-TLX at the end of surgery.
Results:
A total of 369 patients were recruited, of whom 176 underwent RAL and 193 underwent SL (per-protocol analysis). Posture during SL was significantly more challenging for all body parts except the back. There was an increase in discomfort over time (up to 4 h) for the hands and arms, neck, and legs in SL compared with RAL. Perceived physical activity and abilities were rated higher in SL than in RAL (p < 0.01), whereas perceived personal performance was higher in SL (p < 0.01). Perceived physical effort during surgery was lower in RAL than in SL.
Conclusions:
RAL improves the perception of physical workload. Compared with SL, the perceived effort is lower in RAL regardless of the complexity of the surgery.
