About

Bruno V. Mattos is a pioneering hepatobiliary and pancreatic surgeon whose work is redefining the boundaries of minimally invasive oncology. His research centers on advanced robotic techniques for complex liver, bile duct, and pancreatic resections, with a particular focus on hilar cholangiocarcinoma and pancreaticoduodenectomy. Mattos’s major contributions include the development and refinement of the robotic artery-first approach during pancreaticoduodenectomy and the precise excision of the mesopancreas, procedures that enhance oncologic clearance while reducing operative morbidity. His landmark 2020 paper on robotic resection of hilar cholangiocarcinoma (30 citations) established a new standard for treating this challenging malignancy. More recently, his 2024 study on 150 consecutive robotic pancreaticoduodenectomies demonstrated that increasing surgical complexity correlates with decreasing complication rates, a finding that directly supports the safe expansion of robotic programs. With additional work on the Glissonian approach during robotic mesohepatectomy, Mattos continues to push the envelope of what is achievable with minimally invasive surgery, offering patients safer, more effective options for traditionally open procedures.
