Feasibility and safety of robotic liver resection for huge (≥10cm) hepatocellular carcinoma in a single centre: A propensity score-matched single-surgeon study.

Abstract

The applicability of robot-assisted resection for huge hepatocellular carcinoma (HCC) of ≥10cm remains contentious with limited available data. This retrospective analysis involved 337 patients who underwent robotic liver resection for HCC by a single surgeon. Propensity score matching (PSM) was employed to compare perioperative indicators between patients with regular and huge HCC. The regular HCC group exhibited a shorter median operative duration than the huge HCC group. The IWATE criteria revealed higher scores in the huge HCC group than in the regular HCC group. No significant differences were observed between the two groups in Pringle time, drainage tube removal, duration of hospital stays, blood loss volume, blood product transfusion, margin status, conversion rate to open surgery, bile leakage, in-hospital mortality, and reoperation rate. Robotic liver resection is feasible for huge HCC, with effective perioperative risk management potentially improving outcomes for subsequent minimally invasive surgeries.
