About

Stacy A. Brethauer is a leading bariatric surgeon whose research focuses on optimizing surgical outcomes for severe obesity, with a particular emphasis on revisional procedures, cost-effectiveness, and the comparative benefits of robotic versus laparoscopic techniques. Her highly cited work on the conversion of sleeve gastrectomy to Roux-en-Y gastric bypass (116 citations) provides critical guidance for managing patients with inadequate weight loss or complications after initial surgery. She has also made significant contributions to understanding the economic landscape of bariatric surgery, with a study analyzing the cost of these procedures using a national inpatient sample (91 citations). A central theme of her research is the evaluation of robotic surgery; her work comparing totally robotic Roux-en-Y gastric bypass to standard laparoscopic approaches (77 citations) has been instrumental in defining the clinical outcomes and resource utilization associated with this advanced technology. Additionally, she has contributed to patient safety through the development of an algorithm for emergency robotic surgery conversions. With over 300 total citations, Dr. Brethauer’s research directly informs surgical decision-making, healthcare policy, and the safe, effective adoption of new technologies in bariatric surgery.
