First report of surgery for congenital biliary dilatation using the hinotori™ Surgical Robot System (with video)

Abstract

AbstractRobot‐assisted surgery for congenital biliary dilatation has been evolving primarily with the da Vinci® Surgical System. The hinotori™ Surgical Robot System, developed in Japan, received approval for gastroenterological surgery in 2022. We present the inaugural case of congenital biliary dilatation surgery utilizing the hinotori™ system. A 57‐year‐old woman was referred to our institution for evaluation and treatment of common bile duct dilatation classified under Todani Type Ia congenital biliary dilatation. Robotic resection of the extrahepatic bile duct and hepaticojejunostomy with Roux‐en‐Y were performed. The operation lasted 292 min with minimal blood loss (10 mL). The patient had an uneventful postoperative course and was discharged 10 days after surgery. Robotic surgery using the hinotori™ system for congenital biliary dilatation can be safely performed.
