Robotic single-site cholecystectomy with indocyanine green fluorescence for duplicated gallbladder.

Symptomatic gallbladder (GB) duplication is a rare congenital anomaly that poses a significant surgical challenge due to anatomical variability, increasing the risk of bile duct injury or retained GB syndrome. We present the case of a 58-year-old woman with symptomatic cholelithiasis in a duplicated GB, who underwent a robotic single-site cholecystectomy using the da Vinci SP ® system. Intraoperative indocyanine green (ICG) fluorescence imaging was instrumental in delineating the biliary tree, enabling the successful resection of both GBs and their respective cystic ducts and arteries without complications. The articulated instruments of the robotic platform provided the dexterity required for precise dissection, particularly as one GB was partially embedded in the liver parenchyma. This case demonstrates that robotic single-site cholecystectomy with ICG fluorescence imaging is a safe, feasible and effective approach for managing GB duplication, enhancing anatomical identification to minimise surgical risks in aberrant biliary anatomy.
