Fabrizio Michelassi, M.D, F.A.C.S., E.S.A. (Hon.), S.I.C. (Hon.), S.A.C.P.N.E. (Hon.) is the Lewis Atterbury Stimson Professor of Surgery and Chairman of Surgery at Weill Cornell Medicine and Surgeon-in-Chief at NewYork-Presbyterian/Weill Cornell Medical Center. A world-renowned gastrointestinal surgeon with a strong expertise in the surgical treatment of gastrointestinal and pancreatic cancers as well as inflammatory bowel disease, Dr. Michelassi has contributed new insight in the surgical treatment of pancreatic and colorectal cancers, ulcerative colitis and Crohn’s disease though research and participation to multiple clinical trials. His experience and expertise in treating Crohn’s disease led him to develop a novel bowel-sparing procedure, now known as the Michelassi strictureplasty, designed to avoid sacrificing large amounts of bowel at the time of surgery and facilitating quiescence of the acute disease affecting the diseased intestinal loops.
