Background:
The advantages of robotic hepatectomy (Rob-H) over laparoscopic hepatectomy (Lap-H) remain unclear. This study compares the outcomes between Rob-H and Lap-H in a single-center setting.
Methods:
A retrospective analysis was conducted on patients who underwent minimally invasive liver resection between 2014 and 2023. Patient demographics, perioperative parameters, and postoperative outcomes were reviewed. Propensity score matching (PSM) was employed to reduce selection bias.
Results:
A total of 2999 patients were included in this study. 2375 patients underwent Lap-H and 624 patients underwent Rob-H. After PSM, 42 patients who underwent right hemihepatectomy. The results showed that, compared to the Lap-H group, the Rob-H group had lower intraoperative blood loss (P = 0.016). A total of 108 patients who underwent left hemihepatectomy were included. The Rob-H group had shorter operative time (P = 0.005), lower intraoperative blood loss (P = 0.049).For 108 patients who underwent right posterior segmentectomy, the Rob-H group showed shorter operative time (P < 0.001), less intraoperative blood loss (P = 0.012), shorter Pringle duration (P = 0.008).
Conclusion:
Compared with the Lap-H group, intraoperative blood loss and operative time were lower in the Rob-H group, and the results were consistent with previous studies, suggesting that the robotic platform overcome the limitations of laparoscopic liver resection.
