Keith S. Gersin

About

Keith S. Gersin is a leading bariatric surgeon whose research has significantly advanced the safety and efficacy of metabolic surgery. His work primarily focuses on optimizing Roux-en-Y gastric bypass (RYGB) techniques, with key contributions in reducing postoperative complications. Gersin’s landmark 2017 study on robotic gastric bypass demonstrated that the robotic approach may lead to fewer complications compared to traditional laparoscopy, a finding that has garnered over 70 citations and influenced surgical practice. He has also systematically investigated the impact of gastrojejunal anastomotic technique on outcomes, showing how specific methods affect rates of marginal ulcer formation, anastomotic bleeding, and stricture development—critical insights for improving patient recovery. Additionally, his research on RYGB following failed fundoplication provides valuable guidance for complex revisional cases. With multiple highly cited papers, Gersin’s work has helped shape evidence-based standards in bariatric surgery, making him a respected authority in the field whose findings directly enhance surgical decision-making and patient care.
