The weight of BMI in impacting postoperative and oncologic outcomes in pancreaticoduodenectomy is attenuated by a robotic approach

This study was undertaken to observe the effect of body mass index (BMI) on perioperative outcomes and survival when comparing robotic vs ‘open’ pancreaticoduodenectomy. With IRB approval, we prospectively followed 505 consecutive patients who underwent either robotic or ‘open’ pancreaticoduodenectomy from 2012 to 2021. For illustrative purposes, patients were separated based on the Center for Disease Control and Prevention BM I table but regression analysis was utilized to identify significant relationships involving BMI. Data are presented as median (mean ± SD). Significance was determined atp ≤ 0.05. 205 and 300 patients underwent ‘open’ and robotic pancreaticoduodenectomy, respectively. Neither sex nor age correlated with BMI in patients undergoing ‘open’ nor robotic operation. Operative duration correlated with increasing BMI in each operational approach, which was stati stically significant for those receiving the ‘open’ operation (p = 0.02). There were statistically significantly fewer lymph nodes harvested with rising BMI in patients that had an ‘open’ operation (p = 0.01), but no such difference was found in patients undergoing the robotic approach. Length of stay (LOS) and in-hospital mortality were statistically significantly associated with rising BMI when an ‘open’ operation was undertaken (p = 0.02 andp = 0.0002, respectively) but not when the robotic platform was utilized. Patients with higher BMI had signi...
