About

Katerina Neumann is a leading colorectal surgeon and researcher whose work is reshaping surgical care for patients with Crohn’s disease and other colorectal conditions. Her primary research areas include minimally invasive surgery—particularly robotic and laparoscopic approaches—and enhanced recovery after surgery (ERAS) protocols. Neumann’s most impactful contribution is the first meta-analysis and systematic review comparing robotic ileocolic resection to laparoscopic and open surgery for Crohn’s disease, a landmark study that has already garnered 6 citations since its 2025 publication. This work provides critical evidence to guide surgical decision-making and improve patient outcomes. In a large multicenter retrospective study involving 5,503 patients, she also demonstrated how ERAS protocols influence postoperative outcomes across robotic, laparoscopic, and open colorectal surgery, earning 3 citations. Neumann’s research is notable for its rigorous methodology and direct clinical relevance, helping surgeons optimize both technique and recovery pathways. Her work is increasingly cited as a foundation for evidence-based practice in colorectal surgery, making her a rising authority in the field.
