About
Dr. Timothy M. Ullmann is a surgeon-scientist whose research focuses on advancing minimally invasive surgical techniques, particularly in robotic-assisted endocrine and foregut surgery. His major contributions center on demonstrating the safety and efficacy of robotic approaches in complex, high-risk procedures. In a landmark study of 303 consecutive patients, Dr. Ullmann identified key risk factors for perioperative complications in robotic-assisted unilateral adrenalectomy, providing critical guidance for patient selection and surgical planning. His work on robotic reoperative anti-reflux surgery is equally impactful, showing that unlike traditional laparoscopic reoperations—which carry significantly higher morbidity—the robotic approach achieves low perioperative complication rates with high symptom resolution. This finding has important implications for patients requiring revision surgery after failed primary procedures. With over 67 citations across his most-cited works, Dr. Ullmann’s research is helping to establish robotic surgery as a safe and effective option for challenging reoperative cases, expanding the boundaries of what is possible in minimally invasive surgery and improving outcomes for complex surgical patients.
