About

Marianna Zeichen is a leading figure in minimally invasive colorectal surgery, with a particular focus on advanced robotic and laparoscopic techniques. Her research centers on improving surgical outcomes for complex conditions, including diverticular disease, colorectal obstructions, and parastomal hernias. Dr. Zeichen’s most impactful work, cited 55 times, examines the comparative efficacy of laparoscopic versus robotic management for colovesical fistulas—a severe complication of diverticulitis—demonstrating her commitment to refining surgical approaches for challenging pathologies. She has also pioneered the use of self-expanding metallic stents as a bridge to minimally invasive surgery for acute colorectal obstruction, a strategy that reduces mortality associated with emergency procedures. Further expanding the boundaries of robotic surgery, Dr. Zeichen has advanced the robotic retro-rectus repair technique for parastomal hernias, offering patients a less invasive option with improved recovery. Her cumulative work, with papers garnering over 90 citations, underscores her significant contributions to evidence-based surgical innovation, making her a respected authority in the field of colorectal surgery and a key voice in the adoption of robotic platforms for complex abdominal wall and pelvic reconstructions.
