Robotic Completion Radical Cholecystectomy with Fluorescence Guidance

Abstract

The application of minimally invasive surgery (MIS) techniques in the treatment of hepatobiliary malignancies offers advantages of shorter length of stay, quicker functional recovery, and decreased need for postoperative opioids. However, MIS completion radical cholecystectomy for incidentally diagnosed gallbladder cancer can be challenging due to a reoperative field and lack of tactile feedback. This video demonstrates the utility of the robotic platform and highlights the ways in which it assists surgeons in overcoming these limitations. These include (1) versatile wristed instruments and excellent visualization that facilitate a thorough regional lymphadenectomy; and (2) built-in fluorescence imaging technology that can be used with intravenous indocyanine green (ICG) to confirm porta hepatis anatomy in a reoperative field. ICG pharmacokinetics enable fluorescence angiography 15–20\xa0s after ICG injection and fluorescence cholangiography 15–20\xa0min after ICG injection as the dye accumulates in the biliary system. Systematic and intentional application of these techniques allows for the safe performance of robotic completion radical cholecystectomy following sound oncologic principles, with excellent perioperative outcomes.
