Robotic versus standard open pancreatectomy: a propensity score-matched analysis comparison

Interest in robotic pancreatectomy has been greatly increasing over the last decade. However, evidence supporting the benefits of robotic over open pancreatectomy is still outstanding. This study aims to assess the safety and efficacy of robotic pancreatectomy compared with the conventional open surgical approach. Propensity score-matched (1:1) was used to balance age, sex, BMI, ASA, tumor size, and malignancy of 17 robotic pancreaticoduodenectomies (PD), 12 pancreatic enucleations (PE), and 28 distal pancreatectomies (DP); and was compared with the open standard approach. Robotic PD was associated with longer operative time (594 vs. 413min; p=0.03) and decreased blood loss (190 vs. 394ml; p=0.001). Robotic PE showed a lower mean length of hospital stay (8.4 vs. 12.8days; p=0.04) and, in addition, robotic DP showed less blood loss (175 vs. 375ml; p=0.01), less severe morbidities (7.14 vs. 17.9%; p=0.02), and a reduced mean length of hospital stay (8.9 vs. 15.1; p=0.001). Overall, conversion rate was 4 (7%). Robotic pancreatectomy is as safe and effective as the standard open surgical approach with reduced blood loss in PD and DP, length of hospital stay in PE and DP, and severe morbidity in DP.
