Pioneering complex biliary surgeries with the Revo-i robotic surgical system: initial cases of choledochal cyst and...

Robotic surgery systems, including the Korean-developed Revo-i surgical robotic system (Meerecompany Inc.), have expanded from routine cholecystectomies to complex hepatobiliary and pancreatic (HBP) procedures. We report two cases: one of choledochal cyst excision with Roux-en-Y hepaticojejunostomy, and another of extended cholecystectomy for gallbladder cancer, both performed entirely robotically using Revo-i. Both patients recovered without immediate postoperative complications and were discharged on postoperative day 7. These cases are the first to demonstrate the technical feasibility of fully robotic complex HBP surgeries with Revo-i, including the first reported choledochal cyst excision and extended cholecystectomy. Further experience and research are needed to confirm the safety and broader applicability of this system in HBP surgery.
