               extensive experience in robotic pancreatectomy enabled us to successfully implement a robotic surgical
               platform for biliary and hepatic surgery. We started with simple procedures such as peripheral anterolateral
               segmentectomy and left lateral hepatectomy, then gradually progressed to more complex procedures such as
               formal left hepatectomy, caudate lobe resection, and formal right hepatectomy, ultimately achieving the
               most challenging procedures, including robotic resection of hilar cholangiocarcinoma. To the best of our
