A Comparative Study of the Ergonomic Risk to the Surgeon During Vesicoscopic and Robotic Cross-Trigonal Ureteric Reimplantation

A systematic review of ergonomic and muscular strain in surgeons comparing robotic to laparoscopic approaches

Robotic-assisted laparoscopic surgery has become more common in recent years with multiple benefits to patients. However, it poses musculoskeletal risks to surgeons, and given their long careers, it is vital to prolong surgeons' longevity. This review aims to evaluate ergonomic impact and methods of ergonomic assessment in surgeons performing traditional and robotic-assisted laparoscopic surgery. To evaluate the ergonomics and how different body areas were being affected by robotic and laparoscopic surgeons, we performed a systematic review of studies following PRISMA guidelines and focussing on muscular and ergonomic assessment of laparoscopic surgeons. Electronic Ovid Medline and Embase databases were searched on the 15th of June 2023. 16 studies were identified, involving 508 surgeons. 530 traditional laparoscopies and 535 robotic-assisted laparoscopies were included. Mixed methods, including surface electromyography (sEMG) and Borg CR10 physical exertion scale, were used to assess muscular activation and fatigue. Whilst individual studies produced conflicting results, overall sEMG and BORG CR10 scales showed that in TLS the deltoid, triceps, biceps and wrist muscles are most commonly activated. In addition, in RALs, lower back, trapezius and finger muscles were activated most commonly. Muscle activations as a whole were generally lower in robotic-assisted laparoscopy. Survey tools such as NASA-TLX confirmed that overall RALS was less fatiguing than TLS for the majority of surgeons. This review explored the ergonomic risks faced by surgeons performing both traditional laparoscopic and robotic surgery. Further research, including standardised methodology and continuous ergonomic assessment, are warranted to ensure robotic surgery remains safe.

The impact of surgical set-up of endoscopic two surgeon four hand anterior skull base surgeries on surgeons' ergonomics

BACKGROUND

The impact of different surgical set-ups of endoscopic two surgeon four hand anterior skull base surgeries on surgeons' ergonomics remain unclear. This study aims to explore the effect of surgeon, patient and surgical screen positioning on surgeons' ergonomics using the Rapid Entire Body Assessment (REBA) tool.

METHODS

A total of 20 different surgical positions of anterior skull base surgery were simulated and the ergonomic impact on surgeons' neck, truck, leg and wrist were measured using the validated Rapid Entire Body Assessment (REBA) tool. To investigate the ergonomic effect of different surgical setups, the operating surgeon, assisting surgeon, patient head, camera and screen positions were positioned differently in each surgical position.

RESULTS

The lowest REBA Score recorded is 3 whereas the highest score is 8. The REBA scores for the majority of positions are 3 highlighting that these positions are ergonomically favorable. Position 12 is the least ergonomically favorable position with a total REBA score of 19. In this position, operating surgeon is positioned to the right of the patient, assisting surgeon to the left of patient, patient head in central position with camera held by operating surgeon and one screen is placed to the right of patient. Positions 13 and 17 are the most ergonomically favorable positions with a total REBA score of 12. In these positions, the patient's head is positioned to the center, two screens were utilized, and the surgeons were positioned on either side of the patient. The utilization of 2 screens with a central patient head position with the surgeons placed on either side of the patient contribute towards a more ergonomically state in these positions.

CONCLUSIONS

Certain positional behaviors are better at reducing musculoskeletal injury risk when compared to other. Positions with two screens and central head positions are more favourable ergonomically and surgeons should consider this set-up to reduce musculoskeletal injuries during anterior skull base surgery.

Robotic assisted surgery reduces ergonomic risk during minimally invasive colorectal resection: the VOLCANO randomised controlled trial

PURPOSE

Minimally invasive surgery benefits patients but poor operating ergonomics causes musculoskeletal injuries in surgeons. This randomised controlled trial aims to assess whether robotic-assisted surgery with the open-console Versius® system can reduce surgeons' ergonomic risks during major colorectal resections.

METHODS

Prospectively registered at ClinicalTrials.gov (NCT05262296) in March 2022. Adult patients requiring a minimally invasive colorectal resection were potentially eligible. Photographs taken at 2-min intervals were analysed using the objective Rapid Entire Body Assessment (REBA) posture analysis scale to calculate intraoperative surgeon ergonomic risk. Secondary outcomes included team communication (Oxford NOTECHS II), surgeon cognitive strain (modified NASA-TLX scale), and clinical outcomes.

RESULTS

Sixty patients were randomised in a 2:1 ratio (40 robot, 20 laparoscopic). Mean age was 65yrs and 34 (57%) were male. Body Mass Index did not differ between the 2 groups (overall mean 29.0 ± 5) and there were equal proportions of left and right-colonic resections. REBA was significantly lower in the robotic arm (median robot REBA score 3 vs lap REBA 5 [p < 0.001]), equating to an injury risk category drop from "medium" to "low risk". There were no significant differences in team communication, operative duration, or patient outcomes. Surgeon cognitive strain was lower in robotic cases (mean robot 32.4 ± 10.3 vs lap 45.6 ± 14.3 [p < 0.001]).

CONCLUSIONS

This trial demonstrates that robotic surgery with an open-console system reduces ergonomic risk scores and cognitive strain during colorectal resections, with no apparent detriment to team communication. This may therefore be a safe & feasible solution to the increasing problem of work-related musculoskeletal injuries in surgeons.

The Role of the Versius Surgical Robotic System in the Paediatric Population

The uptake of robot-assisted surgery has continuously grown since its advent in the 1990s. While robot-assisted surgery is well-established in adult surgery, the rate of uptake in paediatric surgical centres has been slower. The advantages of a robot-assisted system, such as improved visibility, dexterity, and ergonomics, could make it a superior choice over the traditional laparoscopic approach. However, its implementation in the paediatric surgery arena has been limited primarily due to the unavailability of appropriately sized instruments as per paediatric body habitus, therefore, requiring more technologically advanced systems. The Versius surgical robotic system is a new modular platform that offers several benefits such as articulated instruments which pass through conventional 5 mm ports, compact arms for easier manoeuvrability and patient access, the ability to mimic conventional port placements, and adaptive machine learning concepts. Prior to its introduction to paediatric surgery, it needs to go through a careful pre-clinical and clinical research program.

Work-Related Musculoskeletal Complaints in Surgeons

The aim of the present study was to examine the prevalence of work-related musculoskeletal complaints and potential risk factors among Romanian surgeons. Ninety-five surgeons of different specialties (62.11% males) completed a questionnaire about work-related musculoskeletal complaints (WMSCs). Ninety-one surgeons (95.78%) experienced WMSCs at least in one body part in the last year. Most surgeons reported pain in four body parts (33.68%). The most common WMSCs were reported on the lower back (74.73%), followed by complaints in the neck region (55.79%), shoulder and upper back (46.32%), knee (31.58%), wrist-hand (16.84%), elbow (14.74%), hip (11.58%) and ankle-foot (4.21%). Surgeons rated their pain more severe on upper back, lower back and knees. A higher percentage of male surgeons reported upper back pain (χ²₍₁₎ = 5.818, p = 0.015). Significant age differences were found between the reported pain sites (F_8,278 = 2.666, p = 0.008); the surgeons reporting wrist-hand pain were younger than those reporting neck, shoulders, elbows, dorsal and lumbar pain. Surgeons with significantly less experience in years reported significantly more WMSCs in wrist-hand, hip and ankle-foot regions compared with those more experienced (p < 0.05). Surgeons are at high risk of developing work-related musculoskeletal complaints, which affects both their professional and personal life. Further studies are needed to identify all risk factors and ergonomic strategies to reduce the prevalence and the negative impact of WMSCs.
