Robotic gastrojejunal anastomosis decreases surgeon cognitive workload while maintaining technical precision in bariatric surgery.

• Robotic platform significantly lowers surgeon frustration (p = 0.03) and cognitive load scores in primary (p = 0.001) and complex cases (p < 0.0001).
• Task-specific precision improves with robotics, showing fewer incorrect suture placements (p = 0.03) and missed knot throws (p = 0.004).

Robotic assistance stabilizes performance and reduces stress during complex procedures, leading to better outcomes.
