About

Dr. Chet W. Hammill is a leading figure in minimally invasive and robotic-assisted surgery, with a research focus on optimizing surgical outcomes and cost-effectiveness. His landmark work includes a pivotal 2018 study comparing robotic-assisted versus laparoscopic unilateral inguinal hernia repair, which provided a comprehensive cost analysis that has been cited 85 times, shaping modern surgical decision-making. Dr. Hammill also demonstrated the viability of robotic-assisted Roux-en-Y gastric bypass in community hospital settings, a 2011 study with 84 citations that helped pave the way for broader adoption of advanced bariatric techniques. Beyond these high-impact contributions, he has explored rare oncologic cases, such as his detailed case report on incidental angiosarcoma of the pancreas—a tumor accounting for just 0.1% of pancreatic malignancies—highlighting his commitment to advancing knowledge in challenging, low-incidence diseases. With a career marked by rigorous outcomes research and a dedication to translating innovation into practice, Dr. Hammill’s work has earned over 180 citations, establishing him as a key voice in the evolution of robotic surgery and surgical oncology.
