This randomized controlled trial evaluated the impact of a multifunctional operative support arm on short-term outcomes in 100 women aged 25-40 undergoing laparoscopic surgery for pelvic endometriosis, hydrosalpinx, or benign ovarian cysts. The study found that the device significantly reduced surgeon-reported fatigue by -0.66 on a 0-10 scale (p < 0.001) compared to conventional support, while clinical outcomes remained similar between groups.
Key findings
- Surgeon-reported fatigue decreased by -0.66 with the device compared to conventional support (p < 0.001).
- No significant differences in operative duration, length of stay, or postoperative infection rates were observed.
- Staff reported higher ventilation, temperature control, and comfort scores with the device.
Why it matters
The findings suggest that ergonomic improvements in surgical support can enhance surgeon comfort without compromising clinical outcomes, potentially leading to better performance and reduced fatigue during procedures.
