Assessing visualization in robotic-assisted surgery: demystifying a misty lens.

Area of Science:

• Minimally Invasive Surgery
• Surgical Technology
• Medical Imaging

Background:

• Robotic-assisted surgery (RAS) offers advancements but faces challenges.
• Suboptimal visualization, particularly lens occlusion, remains an issue in RAS.
• Understanding factors contributing to visual distortion is crucial for improving surgical outcomes.

Purpose of the Study:

• To determine the prevalence of suboptimal vision in minimally invasive RAS.
• To identify factors associated with lens occlusion events during robotic surgery.
• To analyze the impact of active instrumentation on visual clarity.

Main Methods:

• Observation of 45 minimally invasive robotic surgeries using Da Vinci XI across general, urology, and OB/GYN subspecialties.
• Monitoring and recording lens occlusion events, defined as visual distortion from debris.
• Tracking lens cleanings and active instrumentation, with statistical analysis of duration-based variables.

Main Results:

• Surgeons experienced visual distortion for 41.4% of operative time.
• Lens occlusion occurred every 24.5 minutes, while cleaning happened every 36.5 minutes.
• Electrocautery devices were significantly more active during occlusion events (37.9%).

Conclusions:

• Suboptimal vision is a significant challenge in robotic-assisted surgery, often exceeding the time needed for lens cleaning.
• The frequent use of electrocautery may contribute to lens occlusion, impacting surgical visualization.
• Further research is needed to explore the effects of occluded visualization on surgical performance and patient outcomes.
