Short‐term outcomes between robot‐assisted and open pancreaticoduodenectomy in patients with high body mass index: A propensity score matched study

BACKGROUND: High body mass index was considered as a risk factor for minimally invasive surgery. The short‐term outcomes of robot‐assisted pancreaticoduodenectomy (RPD) remain controversial. This study aims to investigate the feasibility and advantage of RPD in patients with high body mass index compared to open pancreaticoduodenectomy (OPD). METHODS: Clinical data of 304 patients who underwent pancreaticoduodenectomy from January 2016 to December 2019 in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine was collected. Patients with BMI >25 kg/m(2) were included and divided into RPD and OPD group. After PSM at a 1:1 ratio, 75 patients of OPD and 75 patients of RPD were recorded and analyzed. RESULTS: The RPD group showed advantages in the estimated blood loss (EBL) (323.3 mL vs. 480.7 mL, p = 0.010), the postoperative abdominal infection rate (24% vs. 44%, p = 0.010), the incidence of Clavien‐Dindo III‐V complications (14.7% vs. 28.0%, p = 0.042) over OPD group. CONCLUSION: RPD shows advantages in less EBL, lower incidence rate of Clavien‐Dindo III‐V complications over OPD in overweight and obese patients. RPD was confirmed as a safe and feasible surgical approach for overweight or obsess patients.
