Robotic Liver Resection: Report of Institutional First 100 Cases

Backgrounds: Liver surgery has developed progressively during the last 10 years, especially in minimally invasive approaches. Robotic surgery seemed to overcome laparoscopic limitations with 3D visualization, the increased degrees of freedom given with Endowrist instruments, tremor filtering, better dexterity, and improved ergonomics for the surgeon. Methods: This work was a retrospective analysis of our first 100 robotic hepatectomies from March 2020 to July 2022. Patient demographics characteristics and intra- and postoperative outcomes were analyzed. Results: A total of 59 males and 41 females, with a median age of 68 years, underwent a robotic liver resection. The indications for robotic liver resections were malignant lesions in 86% of patients. Anatomical resection (AR) was undertaken in 27% of cases and non-anatomical resection (NAR) in 63% of cases. None of the patients were converted to the ‘open’ approach. Postoperative complications were as follows: 1% of biliary leakage, 5% of ascites, 6% of pulmonary infections, and 3% of other sites’ infections. CONCLUSIONS Our results showed the satisfactory experience of a tertiary HPB center with its first 100 robotic liver resections. The opportunity to make the robotic approach routinary provided global growth of a surgical team, improving the quality of patient outcomes.
