Abstract
BACKGROUND: We compared surgeons' workload, physical discomfort, and neuromusculoskeletal disorders (NMSDs) across four surgical modalities: endoscopic, laparoscopic, open, and robot-assisted (da Vinci Surgical Systems). METHODS: An electronic survey was sent to the surgeons across an academic hospital system. The survey consisted of 47 questions including: (I) Demographics and anthropometrics; (II) The percentage of the procedural time that the surgeon spent on performing each surgical modality; (III) Physical and mental demand and physical discomfort; (IV) Neuromusculoskeletal symptoms including body part pain and NMSDs. RESULTS: Seventy-nine out of 245 surgeons completed the survey (32.2%) and 65 surgeons (82.2%) had a dominant surgical modality: 10 endoscopic, 15 laparoscopic, 26 open, and 14 robotic surgeons. Physical demand was the highest for open surgery and the lowest for endoscopic and robotic surgeries, (all p < 0.05). Open and robotic surgeries required the highest levels of mental workload followed by laparoscopic and endoscopic surgeries, respectively (all p < 0.05 except for the difference between robotic and laparoscopic that was not significant). Body part discomfort or pain (immediately after surgery) were lower in the shoulder for robotic surgeons compared to laparoscopic and open surgeons and in left fingers for robotic surgeons compared to endoscopic surgeons (all p < 0.05). The prevalence of NMSD was significantly lower in robotic surgeons (7%) compared to the other surgical modalities (between 60 and 67%) (all p < 0.05). CONCLUSIONS: The distribution of NMSDs, workload, and physical discomfort varied significantly based on preferred surgical approach. Although robotic surgeons had fewer overall complaints, improvement in ergonomics of surgery are still warranted.
