Study International Multicentric Pancreatic Left Resections (SIMPLR): Does Surgical Approach Matter?

Simple Summary: Nowadays: minimal invasive distal pancreatectomy is becoming the standard approach for this procedure. Nevertheless, empirical evidence is still needed to validate the advantages associated with the various surgical approaches. This international retrospective multicenter cohort study conducted at three high-volume centers for HPB surgery attempted to compare the perioperative and oncological outcomes of the three primary surgical techniques-open, laparoscopic, and robotic-using propensity score matching analysis. The laparoscopic approach demonstrated notable benefits, including shorter operative times, lower blood loss, and reduced duration of both ICU and hospital stays. Furthermore, the robotic approach exhibited a significantly lower incidence of POPF. Notably, all three techniques demonstrated comparable levels of oncological safety, morbidity, and mortality. Background: Minimally invasive surgery is increasingly preferred for left-sided pancreatic resections. The SIMPLR study aims to compare open, laparoscopic, and robotic approaches using propensity score matching analysis. Methods: This study included 258 patients with tumors of the left side of the pancreas who underwent surgery between 2016 and 2020 at three high-volume centers. The patients were divided into three groups based on their surgical approach and matched in a 1:1 ratio. Results: The open group had significantly higher estimated blood loss (620 mL vs. 320 mL, p < 0.001), longer operative time (273 vs. 216 min, p = 0.003), and longer hospital stays (16.9 vs. 6.81 days, p < 0.001) compared to the laparoscopic group. There was no difference in lymph node yield or resection status. When comparing open and robotic groups, the robotic procedures yielded a higher number of lymph nodes (24.9 vs. 15.2, p = 0.011) without being significantly longer. The laparoscopic group had a shorter operative time (210 vs. 340 min, p < 0.001), shorter ICU stays (0.63 vs. 1.64 days, p < 0.001), and shorter hospital stays (6.61 vs. 11.8 days, p < 0.001) when compared to the robotic group. There was no difference in morbidity or mortality between the three techniques. Conclusion: The laparoscopic approach exhibits short-term benefits. The three techniques are equivalent in terms of oncological safety, morbidity, and mortality.
