BACKGROUND: Laparoscopic liver resection (LAPR) is safe and feasible with a better postoperative course as compared to open resections. Robot-assisted liver surgery (ROBR) is a potential alternative to LAPR. In this study we compare outcomes between ROBR and LAPR. METHODS: Forty patients underwent ROBR and 223 LAPR for various indications. The surgical outcomes of two institutions, each with a specific advanced experience in laparoscopic and robotic surgery, were reviewed. RESULTS: The major hepatectomy rate was significantly higher in LAPR (16.6% vs 0%, p = 0.011) while a parenchyma-preserving approach was favoured in ROBR (55% vs 34.1%, p = 0.019). More nodules were resected in the ROBR group (1.97 ± 1.4 vs 1.57 ± 1.1, p = 0.04). Overall conversion rate was 8/40 (20%) in the ROBR and 17/223 (7.6%) in the LAPR group (p = 0.034). Mean blood loss was 330 ± 303 ml and 174 ± 133 ml for the ROBR and LAPR groups, respectively (p = 0.001) CONCLUSIONS: Despite higher conversion rates and blood loss, robot-assisted surgery may allow the resection of more liver lesions, especially those located in the postero-superior segments, facilitating parenchyma-saving surgery with a comparable complication rate with respect to LAPR.
