Variables affecting surgeons' use of, and preferences for, instrumentation in veterinary laparoscopy.

OBJECTIVE: To investigate the impact of variables on use and preference of common laparoscopic instruments. STUDY DESIGN: Online survey. SAMPLE POPULATION: Surgeons (n = 140) with 3 years or more laparoscopic experience. METHODS: Electronic survey distributed via specialty group LISTSERVEs and Facebook groups. Responses collected included surgeon attributes, preferences, and surgical practice data. Statistical analysis was performed using Fishers exact, ANOVA, Tukey Kramer honestly significant difference (HSD) test, linear regression, and logistic regression. RESULTS: Ninety-eight of 140 respondents answered instrument-related questions and the completion rate of these questions was 76%: 48% of females and 49% of males responded to the survey. The median glove size of respondents was size 7 (range, 5.5 to 8.5). Closing laparoscopic Babcock forceps (p = .018), rotating cup biopsy forceps (p = .003), and manipulating endoscopic staplers (p < .001) were more difficult for surgeons with smaller glove sizes. The median difficulty score for the endoscopic stapler was 4/10 and the median percentage of time this was found difficult was 25%. Reusable instruments were preferred over disposable single-use instruments. The pistol grip was preferred for grasping and retracting (54/98, 55%) and fine dissection (46/96, 48%), while the axial grip was preferred for suturing and knot tying (61/98, 62%). CONCLUSION: Surgeons with smaller glove sizes (<6.5) experience more difficulty when using common laparoscopic instruments. The endoscopic stapler was the most difficult to use. CLINICAL SIGNIFICANCE: When purchasing laparoscopic instrumentation, surgeons should review all available options in handle size and design to improve ergonomics during minimally invasive procedures.

Variables associated with the prevalence of self-reported work-related musculoskeletal disorders in veterinary laparoscopic surgeons.

OBJECTIVE: To investigate the relationship between physical attributes and difficulty performing laparoscopic maneuvers with the prevalence of self-reported musculoskeletal injury. STUDY DESIGN: Online survey. SAMPLE POPULATION: Surgeons (n = 140) with 3 or more years of laparoscopic experience. METHODS: Electronic survey distributed via LISTSERVEs and Facebook groups. Responses collected included surgeon attributes, presence of musculoskeletal injuries, and surgical practice data. Statistical analysis was performed using the Shapiro-Wilk test, linear regression, logistic regression, and Wilcoxon rank sum tests. RESULTS: A total of 52 of the 140 respondents reported a musculoskeletal injury with 38 specifying at least one injury (72%). Neck strain was the most prevalent reported musculoskeletal injury (18/52, 34.6%), followed by shoulder tendinopathies (16/52, 30.8%), arm/hand tendonitis (8/52, 15.4%), carpal tunnel (7/52, 13.5%), back pain (4/52, 7.7%) and arm/hand arthritis (1/52, 1.9%). Women were significantly more likely to report a musculoskeletal problem than men (p = .011) with the odds of women reporting a musculoskeletal injury 2.59 times greater than men. Women and surgeons with smaller glove sizes were significantly more likely to report shoulder tendonitis (p = .034, p = .1) and neck strain (p = .009, p = .001). Respondents with a musculoskeletal problem experienced significantly more difficulty using rotating cup biopsy forceps (p < .001) and perceived this as difficult a greater amount of time (p = .006). CONCLUSION: Female surgeons report more musculoskeletal injuries than their male counterparts. Surgeons with musculoskeletal injuries experience more difficulty performing particular laparoscopic maneuvers. CLINICAL SIGNIFICANCE: Improving ergonomics for women and surgeons with smaller glove sizes must be prioritized to improve surgeon health and laparoscopic instrument use.
