Comparison of efficacy between robotic and open hepatectomy: a systematic review and meta-analysis of propensity...

This meta-analysis evaluates and contrasts the diagnosis and perioperative results involving RLR (robotic liver resection) and open OLR (open liver resection). The researcher used systematic search criteria of databases including MEDLINE, PubMed, Google Scholar, and the Cochrane Library for relevant literature published between January 2000 and January 2025. Eight non-randomized controlled trials were included, each using propensity score matching (PSM), involving 1192 patients. Among them, 557 patients received robotic laparoscopic resection (RLR), while 635 patients underwent open laparoscopic resection (OLR). Undergoing RLR was found to lead to longer surgical times, according to the analysis; however, patients undergoing RLR experienced notably shorter hospital stays compared to those undergoing open liver resection. No significant variations were noted regarding blood loss between the groups, incidence of bile leakage, complication rates, R0 resection margins, or 90-day mortality. RLR demonstrates surgical results similar to those of OLR. Key advantages include shorter hospitalization times and lower complication rates.
