Feasibility and outcomes of robotic colorectal cancer surgery in patients with high body mass index.

Although the median lymph node yield was highest in the robotic cohort (17, range 12–27), followed by the laparoscopic cohort (16, range 14–28), and lowest in the open cohort (15, range 13–28), this difference did not reach statistical significance ( p = 0.108).

Preoperative T stage showed borderline significance reflecting a greater proportion of early stage tumours (T1–T2) in the robotic cohort and a higher prevalence of T4 lesions in the open cohort.
