A comparison of robotic versus laparoscopic distal pancreatectomy: Propensity score matching analysis

Background The aim of this study was to assess the perioperative and pathologic outcomes of robotic distal pancreatectomy compared with a laparoscopic approach. Methods A total of 121 robotic distal pancreatectomies and 992 laparoscopic distal pancreatectomies were retrospectively evaluated, comparing the demographic, perioperative and pathologic outcomes. After 1:2 propensity score matching (PSM) with 11 demographic variables, the factors were analysed again. Results Following PSM, 104 robotic distal pancreatectomy patients were compared with 208 laparoscopic distal pancreatectomy patients. The operation time and proportion of spleen preservation were not different between the groups. The rates of open conversion were lower, whereas the hospital costs were higher in the robotic group. Other perioperative outcomes and pathologic factors did not differ between the groups. Conclusions Although robotic distal pancreatectomy is more expensive, this operation is feasible, with a higher probability of proceeding with the planned operation and with low open conversion rate.

Automated summary

Robotic distal pancreatectomy is more expensive but feasible, with a higher likelihood of completing the planned operation and a lower open conversion rate.
