Optimal laparoscopic ergonomics in gynaecology

Prevalence of musculoskeletal pain among gynecologic surgeons performing laparoscopic procedures: A systematic review and meta-analysis

OBJECTIVE

Musculoskeletal discomfort is associated with repetitive movements and constrained body positions. The current meta-analysis was performed to determine the global prevalence of musculoskeletal symptoms among gynecologic surgeons who perform laparoscopy.

METHODS

Sources included Embase, MEDLINE, PubMed, CINAHL, Web of Science Core Collection, Cochrane Central Register of Controlled Clinical Trials, and Google Scholar. Articles published between 1980 and 2022 were considered. Studies that assessed self-reported musculoskeletal symptoms were included. Relevant data were extracted and tabulated.

RESULTS

Twelve studies met the inclusion criteria. In a pooled sample of 1619 surgeons, the estimated prevalence of musculoskeletal symptoms was 82% (95% confidence interval [CI], 70%-89%; I² , 92%). Female sex was a risk factor, as identified by a pooled odds ratio of 4.64 (95% CI, 2.63-8.19; I² , 0%) compared with male surgeons. Among surgeons who reported musculoskeletal symptoms, 30% (95% CI, 14%-52%; I² , 95%) sought treatment and 3% (95% CI, 2%-6%; I² , 0%) required work hour modifications.

CONCLUSION

The current meta-analysis provides preliminary evidence of a high prevalence of musculoskeletal symptoms among gynecologic laparoscopic surgeons. Future research is needed to explore the underlying risk factors and interventional strategies to mitigate this risk.

The effectiveness of ergonomics interventions in reducing upper limb work-related musculoskeletal pain and dysfunction in sonographers, surgeons and dentists: a systematic review

The aim of this systematic review was to summarise the effects of ergonomics interventions on work-related upper limb musculoskeletal pain and dysfunction, and on productivity in sonographers, surgeons and dentists. A total of 31 studies were included. All studies reported effects on upper limb pain. Nine studies reported effects on dysfunction and only two studies reported effects on productivity. Moderately strong evidence in reducing upper limb pain was found for instigation of microbreaks into long duration surgical procedures, and the use of wider, lighter handles in dental instruments. Moderate evidence was also found for use of prismatic glasses and favourable positioning in reducing upper limb pain. Weak, inconsistent or no evidence was found for all other ergonomics interventions in reducing upper limb pain and dysfunction and increasing productivity. The lack of high quality research, particularly in sonographers and in the outcome of productivity, should be addressed. Practitioner summary: This systematic review investigates the effectiveness of ergonomics interventions on upper limb pain, dysfunction and productivity in sonographers, dentists and surgeons. Instigation of microbreaks during long duration procedures and the use of wider, lighter instrument handles were most effective in reducing upper limb work-related pain.

Muscle activation during traditional laparoscopic surgery compared with robot-assisted laparoscopic surgery: a meta-analysis

BACKGROUND

The repetitive and forceful motions used by operating surgeons increase the risk of developing musculoskeletal disorders. Most ergonomists consider the surgical environment to be incredibly harsh for its workers. Traditional Laparoscopic Surgery (TLS) in particular has a number of physical and mental challenges associated with it, and while Robotic-Assisted Laparoscopic Surgery (RALS) provides several features that improve upon TLS, some surgeons have still reported musculoskeletal symptoms they attribute to RALS. In this paper, we endeavored to systematically review muscle activation for both TLS and RALS, to compare the modalities and present the results as a meta-analysis.

METHODS

A literature search was conducted using Pubmed, Embase, and Cochrane databases in November 2018 with the following inclusion criteria: full text was available in English, the paper contained original data, EMG was one of the primary measurement techniques, and the paper included EMG data for both TLS and RALS. Results from studies were compared using standardized mean difference analysis.

RESULTS

A total of 379 papers were found, and through screening ten were selected for inclusion. Sample populations ranged from 1 to 31 surgeons, and a variety of study designs and metrics were used between studies. The biceps were the only muscle group that consistently and significantly demonstrated lower muscle activation for RALS for all included studies.

CONCLUSIONS

The results may support the belief that RALS is ergonomically superior to TLS, shown through generally lower muscle activation scores. However, these results must be interpreted with caution due to the heterogeneity between the studies and multiple potential sources for bias within studies. This analysis would be strengthened with a higher number of homogenous, high-quality studies examining larger sample sizes.

Human Factors Evaluation of Surgeons' Working Positions for Gynecologic Minimal Access Surgery

STUDY OBJECTIVE

To investigate work-related musculoskeletal disorders (WRMSD) in gynaecological minimal access surgery (MAS), including bariatric (plus size) patients DESIGN: Mixed methods (Canadian Task Force classification III).

SETTING

Teaching hospital in the United Kingdom.

MEASUREMENTS

Survey, observations (anthropometry, postural analysis), and interviews.

RESULTS

Work-related musculoskeletal disorders (WRMSDs) were present in 63% of the survey respondents (n = 67). The pilot study (n = 11) identified contributory factors, including workplace layout, equipment design, and preference of port use (relative to patient size). Statistically significant differences for WRMSD-related posture risks were found within groups (average-size mannequin and plus-size mannequin) but not between patient size groups, suggesting that port preference may be driven by surgeon preference (and experience) rather than by patient size.

CONCLUSION

Some of the challenges identified in this project need new engineering solutions to allow flexibility to support surgeon choice of operating approach (open, laparoscopic or robotic) with a workplace that supports adaptation to the task, the surgeon, and the patient.
