Robotic versus laparoscopic distal pancreatectomy for pancreatic adenocarcinoma in obese patients

摘要

BACKGROUND: Robotic distal pancreatectomy (RDP) is associated with a lower conversion rate and less blood loss than laparoscopic distal pancreatectomy (LDP). LDP has similar oncological outcomes as open surgery in PDAC. The aim of this study was to compare perioperative and oncological outcomes in obese patients with RDP versus LDP for PDAC. MATERIALS AND METHODS: Retrospectively, all obese patients who underwent RDP or LDP for PDAC between 2012 and 2022 at 12 international expert centres were included. RESULTS: out of 372, 81 patients were included. All baseline features were comparable between the two groups. RDP was associated with decreased blood loss (495mlLDP vs. 188mlRDP; p = 0.003), lower conversion rate (13.5%RDP vs. 36.4%LDP; p = 0.019) and lower rate of Clavien-Dindo ≥3 complications (13.5%RDP vs. 36.4%LDP; p = 0.019). Overall and disease-free survival were comparable. CONCLUSIONS: In obese patients with left-sided PDAC, the robotic approach was associated with improved intraoperative outcomes and fewer severe complications.
