Robotic-assisted surgery for left-sided colon and rectal resections is associated with reduction in the postoperative surgical stress response and improved short-term outcomes: a cohort study.

There was a significant trend towards an increasing proportion of overweight and obese patients BMI ≥ 25 kg/m2 in the minimally invasive approaches compared to OS (OS 67.3% LS 74.2% RAS 80.8%, p = 0.004).
