Abstract
BackgroundMinimally invasive liver surgery (MILS) is increasingly performed via the robot-assisted approach but may be associated with increased costs. This study is a post-hoc comparison of healthcare cost expenditure for robotic liver resection (RLR) and laparoscopic liver resection (LLR) in a high-volume center. MethodsIn-hospital and 30-day postoperative healthcare costs were calculated per patient in a retrospective series (October 2015–December 2022). ResultsOverall, 298 patients were included (143 RLR and 155 LLR). Benefits of RLR were lower conversion rate (2.8% vs 12.3%, p = 0.002), shorter operating time (167 min vs 198 min, p = 0.044), and less blood loss (50 mL vs 200 mL, p < 0.001). Total per-procedure costs of RLR (€10260) and LLR (€9931) were not significantly different (mean difference €329 [95% bootstrapped confidence interval (BCI) €-1179–€2120]). Lower costs with RLR due to shorter surgical and operating room time were offset by higher disposable instrumentation costs resulting in comparable intraoperative costs (€5559 vs €5247, mean difference €312 [95% BCI €-25–€648]). Postoperative costs were similar for RLR (€4701) and LLR (€4684), mean difference €17 [95% BCI €-1357–€1727]. When also considering purchase and maintenance costs, RLR resulted in higher total per-procedure costs. DiscussionIn a high-volume center, RLR can have similar per-procedure cost expenditure as LLR when disregarding capital investment.
