[The Short-Term Outcome of Robotic Liver Resection-A Single Institutional Experience].

Introduction: Robotic liver resection(RLR)has been covered by insurance since 2022. We report our short-term outcomes of RLR performed in Kansai Rosai Hospital.

Patients And Method: Between May 2022 and November 2023, 35 patients underwent RLR. Control 789 patients who received laparoscopic liver resection(LLR)between January 2010 and November 2023 were included for comparison.

Results: No significant differences were noted between non-anatomical RLR and anatomical RLR groups with respect to blood loss, Pringle rate, conversion rate, biliary fistula and hospital stay, respectively. Difficulty score was higher(4.07 vs 7.71 p<0.0001)and console time was longer(212 vs 331 min p=0.0035)in anatomical RLR group than non-anatomical RLR group. No significant differences were noted between RLR and LLR groups with respect to patient age, gender, Child-Pugh, liver damage and diagnosis, respectively. Anatomical LR rate was higher(18/17 vs 534/255, 48.6 vs 32.3%, p=0.0454)and open conversion rate was lower(0 vs 0.5%, p=0.0296)in RLR group than LLR group. No significant differences were noted between RLR and LLR groups with respect to blood loss, postoperative mortality, morbidity and hospital stay, respectively.

Conclusion: Although further studies are still needed to confirm the benefit of RLR, RLR is safe, minimally invasive, and effective approach to the management of liver tumor.
