Abstract
INTRODUCTION: Most liver resections performed in the United States are open. With the ever-increasing role of robotic surgery, our study's role is to assess national outcomes based on the surgical approach. METHODS: We performed a retrospective analysis of the 2015 National Readmission Database (NRD). We selected patients undergoing open, laparoscopic, and robotic hepatectomy. Propensity score matching was performed to match the three groups in terms of demographics, hospital characteristics, and resection type. Our primary outcome was 6-month readmission rates and associated costs. RESULTS: 3,872 patients were included in the analysis (open = 3,420, laparoscopic = 343, and robotic = 109). Robotic liver resection has lower 6-month readmission rates (18.3%) than the laparoscopic (26.7%) and open (30%) counterparts. The robotic approach was more cost-effective ($127,716.56 ± 12,567.31) than the open ($157,880.82 ± 18,560.2) and laparoscopic approach ($152,060.78 ± 8,890.13) in terms of the total cost which includes cost per readmission. CONCLUSIONS: There is a financial benefit of using robotics in terms of cost, hospital length of stay, and readmission rates in patients undergoing liver resection, cost.
