About
Ralph Peterli is a pioneering bariatric and upper GI surgeon whose work has fundamentally shaped modern metabolic surgery. His research centers on the comparative effectiveness of surgical techniques for severe obesity and complex hiatal hernia repair, with a particular focus on optimizing patient outcomes through rigorous clinical trials. Peterli is best known for leading the landmark SM-BOSS trial, which provided long-term evidence establishing Roux-en-Y gastric bypass and sleeve gastrectomy as durable, effective procedures, directly influencing international treatment guidelines. His work has garnered thousands of citations, reflecting its profound impact on clinical practice. Beyond bariatrics, he has advanced the field of robotic surgery, notably through the prospective RATHER-study, which demonstrated the safety and feasibility of robot-assisted repair for complete upside-down stomach hernias—a technically demanding condition. Peterli’s contributions extend to mentoring a generation of surgeons and shaping evidence-based standards in minimally invasive surgery. His career exemplifies how high-quality, patient-centered research can transform surgical care and improve lives.
