Dr. Michelassi's bio

This content was provided by Dr. Michelassi "A prolific author of more than 270 papers, book chapters and abstracts, Dr. Michelassi has contributed new insight in the surgical treatment of pancreatic and colorectal cancers, ulcerative colitis and Crohn's disease. He has pioneered the development of important new techniques that ensure better outcomes and improved quality of life for patients with rectal cancer and ulcerative colitis. These techniques have resulted in a greater percentage of patients avoiding permanent stomas and maintaining urological and sexual function. His recognized expertise in the surgical treatment of pancreatic cancer has led many patients to seek his counsel; in turn, Dr. Michelassi has contributed new knowledge to this field through 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. He has edited a book on "Operative strategies in inflammatory bowel disease" and has produced eleven instructional movies for surgeons on the surgical treatment of complications of Crohn's disease and ulcerative colitis. Internationally renowned as an outstanding clinician, researcher and teacher, Dr. Michelassi has been invited to be a visiting professor at close to 50 national and international institutions. He has delivered more than 40 named lectures and keynote addresses. He is Associate Editor of the Annuals of Surgical Oncology and serves on the editorial board of five prestigious medical journals including: The Journal of Gastrointestinal Surgery, Surgery, The British Journal of Surgery, Annals of Surgery and the World Journal of Surgery.
