A Contemporary Review of Robotic Resection for Hepatocellular Carcinoma

Background: Robotic hepatectomy represents an appealing treatment modality for resectable hepatocellular carcinoma (HCC). A contemporary review of robotic hepatectomy compared to laparoscopic/open hepatectomy is necessary. Methods: We performed a literature review to identify studies between 2018-2024 comparing robotic to laparoscopic/open hepatectomy for HCC with measurable outcomes. Results: A total of 10 studies were identified, including 943 patients undergoing robotic hepatectomy compared to 1678 patients undergoing laparoscopic/open hepatectomy. Generally, while similar short/long-term survival was noted across all resection modalities, robotic hepatectomy was associated with longer operative time, shorter length of stay, and less post-operative complications. An additional 4 studies were evaluated in the context of HCC, reviewing the prognostic value of robotic hepatectomy margins, robotic hepatectomy in the context of metabolic syndrome, "huge" (>10 cm) HCCs, and robotic hepatectomy vs. microwave ablation. Conclusions: Robotic hepatectomy is a safe alternative to laparoscopic/open hepatectomy for HCC that provides similar oncological/long-term outcomes, while potentially decreasing post-operative complications and length of stay.
