Improving performance under mirror-image conditions during laparoscopic surgery using the Broadview camera system.

Area of Science:

• Minimally Invasive Surgery
• Surgical Education
• Human Factors Engineering

Background:

• Mirror-image conditions in surgery can impair surgeon performance and lead to errors.
• Quantitative assessment of surgical difficulty under mirrored views is crucial for improving training and technology.

Purpose of the Study:

• To quantitatively evaluate the performance challenges faced by surgeons during laparoscopic procedures under mirror-image conditions.
• To identify technological solutions, such as camera systems, that can mitigate these challenges and enhance surgical outcomes.

Main Methods:

• Assessed surgical performance using the Hiroshima University Endoscopic Surgical Assessment Device (HUESAS) in 12 novices and 10 experienced surgical residents.
• Measured deviation with integrated time, approaching time, and peak velocity under coaxial (0°) and mirror-image (180°) conditions, with and without the Broadview camera system.

Main Results:

• Experienced residents outperformed novices at 0°, but both groups showed significantly worse performance at 180° compared to 0°.
• The Broadview camera system significantly improved all HUESAS assessment metrics at 180° for both novice and experienced surgeons (P < 0.0001).

Conclusions:

• Laparoscopic surgery under mirror-image conditions presents quantifiable performance deficits.
• The Broadview camera system offers a viable solution to enhance surgeon performance and reduce difficulty in mirror-image laparoscopic surgery.
